Cannabis Manufacturing Considerations: From Raw Materials to Finished Goods

By David Vaillencourt, Kathleen May
No Comments

Facility layout and design are important components of overall operations, both in terms of maximizing the effectiveness and efficiency of the process(es) executed in a facility, and in meeting the needs of personnel. Prior to the purchase of an existing building or investing in new construction, the activities and processes that will be conducted in a facility must be mapped out and evaluated to determine the appropriate infrastructure and flow of processes and materials. In cannabis markets where vertical integration is the required business model, multiple product and process flows must be incorporated into the design and construction. Materials of construction and critical utilities are essential considerations if there is the desire to meet Good Manufacturing Practice (GMP) compliance or to process in an ISO certified cleanroom. Regardless of what type of facility is needed or desired, applicable local, federal and international regulations and standards must be reviewed to ensure proper design, construction and operation, as well as to guarantee safety of employees.

Materials of Construction

The materials of construction for interior work surfaces, walls, floors and ceilings should be fabricated of non-porous, smooth and corrosive resistant surfaces that are easily cleanable to prevent harboring of microorganisms and damage from chemical residues. Flooring should also provide wear resistance, stain and chemical resistance for high traffic applications. ISO 22196:2011, Measurement Of Antibacterial Activity On Plastics And Other Non-Porous Surfaces22 provides a method for evaluating the antibacterial activity of antibacterial-treated plastics, and other non-porous, surfaces of products (including intermediate products). Interior and exterior (including the roof) materials of construction should meet the requirements of ASTM E108 -11, Standard Test Methods for Fire Tests of Roof Covering7, UL 790, Standard for Standard Test Methods for Fire Tests of Roof Coverings 8, the International Building Code (IBC) 9, the National Fire Protection Association (NFPA) 11, Occupational Safety and Health Administration (OSHA) and other applicable building and safety standards, particularly when the use, storage, filling, and handling of hazardous materials occurs in the facility. 

Utilities

Critical and non-critical utilities need to be considered in the initial planning phase of a facility build out. Critical utilities are the utilities that when used have the potential to impact product quality. These utilities include water systems, heating, ventilation and air conditioning (HVAC), compressed air and pure steam. Non-critical utilities may not present a direct risk to product quality, but are necessary to support the successful, compliant and safe operations of a facility. These utilities include electrical infrastructure, lighting, fire detection and suppression systems, gas detection and sewage.

  1. Water
Microbial monitoring methods can include frequent/consistent testing

Water quality, both chemical and microbial, is a fundamental and often overlooked critical parameter in the design phase of cannabis operations. Water is used to irrigate plants, for personnel handwashing, potentially as a component in compounding/formulation of finished goods and for cleaning activities. The United States Pharmacopeia (USP) Chapter 1231, Water for Pharmaceutical Purposes 2, provides extensive guidance on the design, operation, and monitoring of water systems. Water quality should be tested and monitored to ensure compliance to microbiological and chemical specifications based on the chosen water type, the intended use of the water, and the environment in which the water is used. Microbial monitoring methods are described in USP Chapter 61, Testing: Microbial Enumeration Tests 3and Chapter 62, Testing: Tests for Specified Microorganisms 4, and chemical monitoring methods are described in USP Chapter 643, Total Organic Carbon 5, and Chapter 645, Water Conductivity 6.Overall water usage must be considered during the facility design phase. In addition to utilizing water for irrigation, cleaning, product processing, and personal hygiene, water is used for heating and cooling of the HVAC system, fogging in pest control procedures and in wastewater treatment procedures  A facility’s water system must be capable of managing the amount of water required for the entire operation. Water usage and drainage must meet environmental protection standards. State and local municipalities may have water usage limits, capture and reuse requirements and regulations regarding runoff and erosion control that must also be considered as part of the water system design.

  1. Lighting

Lighting considerations for a cultivation facility are a balance between energy efficiency and what is optimal for plant growth. The preferred lighting choice has typically been High Intensity Discharge (HID) lighting, which includes metal halide (MH) and high-pressure sodium (HPS) bulbs. However, as of late, light-emitting diodes (LED) systems are gaining popularity due to increased energy saving possibilities and innovative technologies. Adequate lighting is critical for ensuring employees can effectively and safely perform their job functions. Many tasks performed on the production floor or in the laboratory require great attention to detail. Therefore, proper lighting is a significant consideration when designing a facility.

Proper lighting is a significant consideration when designing a facility.

Environmental factors, such as temperature, relative humidity (RH), airflow and air quality play a significant role in maintaining and controlling cannabis operations. A facility’s HVAC system has a direct impact on cultivation and manufacturing environments, and HVAC performance may make or break the success of an operation. Sensible heat ratios (SHRs) may be impacted by lighting usage and RH levels may be impacted by the water usage/irrigation schedule in a cultivation facility. Dehumidification considerations as described in the National Cannabis Industry Association (NCIA) Committee Blog: An Introduction to HVACD for Indoor Plant Environments – Why We Should Include a “D” for Dehumidification 26 are critical to support plant growth and vitality, minimize microbial proliferation in the work environment and to sustain product shelf-life/stability. All of these factors must be evaluated when commissioning an HVAC system. HVAC systems with monitoring sensors (temperature, RH and pressure) should be considered. Proper placement of sensors allows for real-time monitoring and a proactive approach to addressing excursions that could negatively impact the work environment.

  1. Compressed Air

Compressed air is another, often overlooked, critical component in cannabis operations. Compressed air may be used for a number of applications, including blowing off and drying work surfaces and bottles/containers prior to filling operations, and providing air for pneumatically controlled valves and cylinders. Common contaminants in compressed air are nonviable particles, water, oil, and viable microorganisms. Contaminants should be controlled with the use appropriate in-line filtration. Compressed air application that could impact final product quality and safety requires routine monitoring and testing. ISO 8573:2010, Compressed Air Specifications 21, separates air quality levels into classes to help differentiate air requirements based on facility type.

  1. Electrical Infrastructure

Facilities should be designed to meet the electrical demands of equipment operation, lighting, and accurate functionality of HVAC systems. Processes and procedures should be designed according to the requirements outlined in the National Electrical Code (NEC) 12, Institute of Electrical and Electronics Engineers (IEEE) 13, National Electrical Safety Code (NESC) 14, International Building Code (IBC) 9, International Energy Conservation Code (IECC) 15 and any other relevant standards dictated by the Authority Having Jurisdiction (AHJ).

  1. Fire Detection and Suppression

“Facilities should be designed so that they can be easily expanded or adjusted to meet changing production and market needs.”Proper fire detection and suppression systems should be installed and maintained per the guidelines of the National Fire Protection Association (NFPA) 11, International Building Code (IBC) 9, International Fire Code (IFC) 10, and any other relevant standards dictated by the Authority Having Jurisdiction (AHJ). Facilities should provide standard symbols to communicate fire safety, emergency and associated hazards information as defined in NFPA 170, Standard for Fire Safety and Emergency Symbols 27.

  1. Gas detection

Processes that utilize flammable gasses and solvents should have a continuous gas detection system as required per the IBC, Chapter 39, Section 3905 9. The gas detection should not be greater than 25 percent of the lower explosive limit/lower flammability limit (LEL/LFL) of the materials. Gas detection systems should be listed and labeled in accordance with UL 864, Standard for Control Units and Accessories for Fire Alarm Systems 16 and/or UL 2017, Standard for General-Purpose Signaling Devices and Systems 17 and UL 2075, Standard for Gas and Vapor Detectors and Sensors 18.

Product and Process Flow

Product and process flow considerations include flow of materials as well as personnel. The classic product and process flow of a facility is unidirectional where raw materials enter on one end and finished goods exit at the other. This design minimizes the risk of commingling unapproved and approved raw materials, components and finished goods. Facility space utilization is optimized by providing a more streamlined, efficient and effective process from batch production to final product release with minimal risk of errors. Additionally, efficient flow reduces safety risks to employees and an overall financial risk to the organization as a result of costly injuries. A continuous flow of raw materials and components ensures that supplies are available when needed and they are assessable with no obstructions that could present a potential safety hazard to employees. Proper training and education of personnel on general safety principles, defined work practices, equipment and controls can help reduce workplace accidents involving the moving, handling, and storing of materials. 

Facilities Management

Facilities management includes the processes and procedures required for the overall maintenance and security of a cannabis operation. Facilities management considerations during the design phase include pest control, preventative maintenance of critical utilities, and security.

Damage from whiteflies, thrips and powdery mildew could be prevented with an appropriate PCP

A Pest Control Program (PCP) ensures that pest and vermin control is carried out to eliminate health risks from pests and vermin, and to maintain the standards of hygiene necessary for the operation. Shipping and receiving areas are common entryways for pests. The type of dock and dock lever used could be a welcome mat or a blockade for rodents, birds, insects, and other vermin. Standard Operating Procedures (SOPs) should define the procedure and responsibility for PCP planning, implementation and monitoring.

Routine preventative maintenance (PM) on critical utilities should be conducted to maintain optimal performance and prevent microbial and/or particulate ingress into the work environment. Scheduled PMs may include filter replacement, leak and velocity testing, cleaning and sanitization, adjustment of airflow, the inspection of the air intake, fans, bearings and belts and the calibration of monitoring sensors.

In most medical cannabis markets, an established Security Program is a requirement as part of the licensing process. ASTM International standards: D8205 Guide for Video Surveillance System 23, D8217 Guide for Access Control System[24], and D8218 Guide for Intrusion Detection System (IDS) 25 provide guidance on how to set up a suitable facility security system and program. Facilities should be equipped with security cameras. The number and location of the security cameras should be based on the size, design and layout of the facility. Additional cameras may be required for larger facilities to ensure all “blind spots” are addressed. The facility security system should be monitored by an alarm system with 24/7 tracking. Retention of surveillance data should be defined in an SOP per the AHJ. Motion detectors, if utilized, should be linked to the alarm system, automatic lighting, and automatic notification reporting. The roof area should be monitored by motion sensors to prevent cut-and-drop intrusion. Daily and annual checks should be conducted on the alarm system to ensure proper operation. Physical barriers such as fencing, locked gates, secure doors, window protection, automatic access systems should be used to prevent unauthorized access to the facility. Security barriers must comply with local security, fire safety and zoning regulations. High security locks should be installed on all doors and gates. Facility access should be controlled via Radio Frequency Identification (RFID) access cards, biometric entry systems, keys, locks or codes. All areas where cannabis raw material or cannabis-derived products are processed or stored should be controlled, locked and access restricted to authorized personnel. These areas should be properly designated “Restricted Area – Authorized Personnel Only”.

Future Expansion

The thought of expansion in the beginning stages of facility design is probably the last thing on the mind of the business owner(s) as they are trying to get the operation up and running, but it is likely the first thing on the mind of investors, if they happen to be involved in the business venture. Facilities should be designed so that they can be easily expanded or adjusted to meet changing production and market needs. Thought must be given to how critical systems and product and process flows may be impacted if future expansion is anticipated. The goal should be to minimize down time while maximizing space and production output. Therefore, proper up-front planning regarding future growth is imperative for the operation to be successful and maintain productivity while navigating through those changes.

Reducing Cross Contamination in Your Lab

By Nathan Libbey
No Comments

Cross Contamination

Cross Contamination – noun – “inadvertent transfer of bacteria or other contaminants from one surface, substance, etc., to another especially because of unsanitary handling procedures. – (Mariam Webster, 2021). Cross contamination is not a new concept in the clinical and food lab industries; many facilities have significant design aspects as well as SOPs to deliver the least amount of contaminants into the lab setting. For cannabis labs, however, often the exponential growth leads to a circumstance where the lab simply isn’t large enough for the number of samples processed and number of analytical instruments and personnel needed to process them. Cross contamination for cannabis labs can mean delayed results, heightened occurrences of false positives, and ultimately lost customers – why would you pay for analysis of your clean product in a dirty facility? The following steps can save you the headaches associated with cross contamination:

Wash (and dry) your hands properly

Flash back to early pandemic times when the Tik Tok “Ghen Co Vy” hand washing song was the hotness – we had little to no idea that the disease would be fueled mostly by aerosol transmission, but the premise is the same, good hand hygiene is good to reduce cross contamination. Hands are often the source of bacteria, both resident (here for the long haul; attached to your hands) and transient (easy to remove; just passing through), as they come into contact with surfaces from the bathroom to the pipettor daily (Robinson et al, 2016). Glove use coupled with adequate hand washing are good practices to reduce cross contamination from personnel to a product sample. Additionally, the type of hand drying technique can reduce the microbial load on the bathroom floors and, subsequently tracked into the lab. A 2013 study demonstrated almost double the contamination from air blade technology versus using a paper towel to dry your hands (Margas et al, 2013).

Design Your Lab for Separation

Microbes are migratory. In fact, E. coli can travel at speeds up to 15 body lengths per second. Compared to the fastest Olympians running the 4X100m relay, with an average speed of 35 feet per second or 6 body lengths, this bacterium is a gold medal winner, but we don’t want that in the lab setting (Milo and Phillips, 2021). New lab design keeps this idea of bacterial travel in mind, but for those labs without a new build, steps can be made to prevent contamination:

  • Try to keep traffic flow moving in one direction. Retracing steps can lead to contamination of a previous work station
  • Use separate equipment (e.g. cabinets, pipettes) for each process/step
  • Separate pre- and post-pcr areas
  • Physical separation – use different rooms, add walls, partitions, etc.

Establish, Train and Adhere to SOPs

Design SOPs that include everything- from hygiene to test procedures and sanitation.

High turnover for personnel in labs causes myriad issues. It doesn’t take long for a lab that is buttoned up with cohesive workflows to become a willy-nilly hodgepodge of poor lab practices. A lack of codified Standard Operating Procedures (SOPs) can lead to a lab rife with contaminants and no clear way to troubleshoot the issue. Labs should design strict SOPs that include everything from hand hygiene to test procedures and sanitation. Written SOPs, according to the WHO, should be available at all work stations in their most recent version in order to reduce biased results from testing (WHO, 2009). These SOPs should be relayed to each new employee and training on updated SOPs should be conducted on an ongoing basis. According to Sutton, 2010, laboratory SOPs can be broken down into the following categories:

  • Quality requirements
  • Media
  • Cultures
  • Equipment
  • Training
  • Sample handling
  • Lab operations
  • Testing methodology
  • Data handling/reporting/archiving
  • Investigations

Establish Controls and Monitor Results

It may be difficult for labs to keep tabs on positivity and fail rates, but these are important aspects of a QC regimen. For microbiological analysis, labs should use an internal positive control to validate that 1) the method is working properly and 2) positives are a result of target analytes found in the target matrix, not an internal lab contamination strain. Positive controls can be an organism of choice, such as Salmonella Tranoroa, and can be tagged with a marker, such as Green Fluorescent Protein in order to differentiate the control strain. These controls will allow a lab tech to discriminate between a naturally contaminated specimen vs. a positive as a result of cross-contamination.

Labs should, in addition to having good QC practices, keep track of fail rates and positivity rates. This can be done as total lab results by analysis, but also can be broken down into customers. For instance, a lab fail rate for pesticides averages 4% for dried flower samples. If, during a given period of review, this rate jumps past 6% or falls below 2%, their may be an issue with instrumentation, personnel or the product itself. Once contamination is ruled out, labs can then present evidence of spikes in fail rates to growers who can then remediate in their own facilities. These efforts in concert will inherently drive down fail rates, increase lab capacity and efficiency, and result in cost savings for all parties associated.

Continuous Improvement is the Key

Cannabis testing labs are, compared to their food and clinical counterparts, relatively new. The lack of consistent state and federal regulation coupled with unfathomable growth each year, means many labs have been in the “build the plane as you fly” mode. As the lab environment matures, simple QC, SOP and hygiene changes can make an incremental differences and drive improvements for labs as well as growers and manufacturers they support. Lab management can, and should, take steps to reduce cross contamination, increase efficiency and lower costs; The first step is always the hardest, but continuous improvement cannot begin until it has been taken.

Quality Systems 101: CAPA Programs Drive Improvement & Prevent Costly Mistakes

By David Vaillencourt

PlantTag

No business is perfect, especially when humans are part of the equation. But, how do you tackle fixing quality issues as they arise? The goal of this article is to shed some light on the value of a CAPA program and why many states are making them mandatory for cannabis businesses.

Let’s consider the following situations:

  • Analytical lab results for a production batch test above the limit for a banned pesticide or microbial contamination
  • You open a case of tincture bottles and some are broken
  • A customer returns a vape pen because it is leaking or ‘just doesn’t work’

Do you…

  • Document the issue?
  • Perform some sort of an investigation, asking questions of the people involved?
  • Ask for a retest? Then, if the test comes back positive, move on?

Let’s go through each one of these and understand why the suboptimal answer could be costing your business money:

You don’t document the issue

I hear excuses for skipping on documentation all the time.

  • “It’s not a big deal”
  • “It was a one off”
  • “The glasses probably broke in transit”
  • “They are cheap and easily replaceable”
  • “It’s not worth the time”
Tracking and documenting supplier shipments can help you identify supply chain issues.

In the situation of a couple of broken bottles in a shipment, what if it was the seventh time in the last two months? If you haven’t been documenting and tracking the issue, you have no way of knowing if it was a single occurrence. Remember when you were surprised that your filling team did not have enough bottles? Those broken bottles add up. Without documenting the incident, you will never know if it was truly a one-time mistake or the sign of a deeper issue. The reality is, it could be sloppy handling on the production line, issues with the shipper or even a sign of poor quality coming from the supplier.

Have you ever compared the number of fills vs the number of bottles ordered? How much money have you already lost due to those broken bottles adding up? Do you have the ability to answer this question?

You perform an investigation

Let’s say a customer returns a leaky vape pen. You perform an investigation by asking the production workers what they think went wrong. They say that it’s very difficult to get the seal for the cartridge into place. Their supervisor tells them to try harder, refunds the customer and moves on. But, why is it difficult to get the seal into place? Is it a design flaw? Should a special tool be used to assemble the cartridge properly? Without getting to the root cause of why the seals are leading to leaking cartridges, you are doomed to have repeat issues. Numerous studies have found that less than one in twenty dissatisfied customers will complain, and that approximately one in ten will simply leave for another brand or provider. How much is this unresolved issue truly costing your business?

Asking for a retest and if it passes, releasing the product and moving on.

labsphoto
In Colorado, 15% of the final tested cannabis flower products continue to fail.

Suppose a major producer of cereal received test results for its most popular cereal that were positive for levels of heavy metals that research has shown to be linked to cancer or developmental issues in children. Now, suppose the company stated that it was an isolated incident and a retest showed that the product met acceptable limits. Further investigation showed no paperwork, save for a couple of emails and a phone call between the lab and the producer. Would that give you peace of mind? This is known as “testing into compliance” and was the subject of a landmark lawsuit in 1993 that Barr Laboratories lost.

For many the answer would be a hard NO. But this happens every day. In Colorado, 12.5% of cannabis batches failed final product testing in 2018 and 2019. That’s one in eight batches! What happened to those products? Good question.

Enter: CAPA (Corrective Action and Preventive Action) programs! For people with a background in quality and GMPs (Good Manufacturing Practices), CAPA is a household name. And, it’s quickly becoming a requirement that cannabis regulatory bodies are looking at. Colorado was the first state to explicitly require CAPA programs for all license holders effective January of this year and has provided a free resource for them. But, for the large majority of people, including those in the cannabis industry, it’s just another acronym.

What does a CAPA program do?

The benefits are numerous but two major ones are:

An effective tool for investigating the true root cause

First of all, a CAPA program provides the framework for a tool for investigation – as Murphy’s Law posits – things go wrong all of the time. Whether you have a manual, labor-intensive process or a highly automated operation, the equipment is programmed, maintained and monitored by humans. The logical sequence of problem solving within a CAPA program allows you to thoroughly investigate and determine the root cause of the issue. With a complete understanding of root cause, you are then able to eliminate it and prevent future occurrences – not just in the one area investigated, but in all similar situations throughout the company.

System for continuous improvement

Gathering info from a customer complaint like batch or product IDs can be crucial in a CAPA system

Anyone who is in the market for a new car lately can appreciate the technological advances. In the 1980s, it was air bags and ABS brakes (those of you that drive in snowy climates and remember having to pump your brakes can appreciate technological advancements). Bluetooth technology for hands-free communication and radio control is another example of continuous improvement in cars.

This is one of the biggest predictors and differentiators between profitable and successful companies with satisfied clients and one that is barely scraping by. The cost of poor quality adds up!

Key inputs in a CAPA system 

If the output is an improved system and lower cost of quality, we need to make sure we’re considering the potential inputs. 

Information that feeds into your CAPA system:

Customer complaints

Every complaint must be recorded. Gather as much information as possible, but at a minimum: the product type/SKU, the customer name and date of purchase. If possible, the batch or product ID.

This is not necessarily to identify products for a recall, but to prevent…

Laboratory test results

This should not be restricted to final product testing, but include any in-process inspections. Say you have a product repeatedly failing final testing, what if it’s actually been consistently failing or very close to failing at the very first in-process inspection? It’s also important to work with your laboratory to understand their method validation process, including the accuracy, precision, robustness, etc.

Infrastructure & environmental controls/monitoring

Most people consider “environmental controls” to be things like temperature and humidity control. While that is true, it can also include pest and contamination control. Poorly designed infrastructure layouts are major contributors to product cross contamination as well.

Supplier information

Undetected supply chain issues (remember the broken bottles?) can add up fast! CAPAs for suppliers cannot just include supplier monitoring, but improvement in how you communicate your needs to your suppliers. It’s easy to overlook non-cannabis raw materials as sources of microbiological and chemical contamination. Conduct a risk assessment based on the type of contact with your product and the types of contamination possible and adjust your supplier qualification program accordingly.

Are you ready to recognize the benefits of a CAPA program?

One more major benefit of CAPA programs to mention before we go is … Preventive via predictive analytics.

In Colorado, 15% of the final tested cannabis flower products continue to fail, mostly due to mold and mildew. A quality system, with effective data capture that is funneled into a CAPA program can easily reduce this by 75%. For even a small business doing $2M per year in revenue, that equates to a revenue increase of nearly $200,000 with no additional expenses.

Whether you are operating in the State of Colorado or elsewhere, a CAPA and Recall program will provide immense value. In the best case, it will uncover systemic issues; worst case, it forces you to fix mild errors. What are you waiting for?

Challenges with Process Scale Up in Cannabis/Hemp Extraction

By Darwin Millard
No Comments

What makes scaling up your process so difficult?

There are many factors that can lead to the challenges people face when scaling up their processes. These challenges are not unique to the cannabis/hemp industry, but they are exacerbated by the consequences generated from decades of Reefer Madness. In my time operating in the cannabis/hemp space, 15+ years, I have seen established equipment vendors and sellers of laboratory supplies, like Sigma-Aldrich (now Millipore-Sigma), Fisher-Scientific, Cerilliant, Agilent, and others, go from reporting individuals inquiring about certified reference materials to setting up entire divisions of their companies to service the needs of the industry. Progress. But we are still a fledgling marketplace facing many challenges. Let’s look at a few specific to process scale up.

Darwin Millard will deliver a presentation on this topic during the Cannabis Extraction Virtual Conference on June 29. Click here to learn more.Equipment Availability: Lack of available equipment at larger and larger process scales can severely impact project timelines. Making not only equipment acquisition difficult, but also limiting the number of reputable equipment manufacturers you can work with.

Non-Linear Expansion: NEVER assume your process scales linearly. Perhaps one of the most avoidable mistakes during process scale up. You will quickly find that for many processes you cannot just put in a larger unit and expect a proportional increase in output. This is because as process equipment increases so to must utilities and other supporting infrastructure, but not only that, process vessel geometry, proportions, and design are contributing factors to process efficiency as your scale of operations increases.

Hazardous Material Quantities: Just as important to the process as the equipment are the solvents and reagents used. As your scale of operations increases so does your demand and production of hazardous materials; solvents including carbon dioxide (CO2), ethanol, and liquid petroleum gases (LPG) like Butane and Propane are obvious hazards, but so too are the refrigerants used in the chillers, fuels used to power generators, steam created to heat critical systems, and effluents and wastewater discharged from the process and supporting systems. Not every municipality wants thousands of gallons of flammable substances and hazardous waste being generated in their backyard…

Contractor/Vendor Misrepresentation: Finding out in the middle of you project that your contractor or equipment vendor has never set up a system at this scale before is never a good feeling. Unfortunately, contractor and vendor misrepresentation of qualifications is a common occurrence in the cannabis/hemp space.

If all this was not bad enough, all too often the consequences of improper planning and execution are not felt until your project is delayed or jeopardized due to misallocation of funds or undercapitalization. This is especially true when scaling up your production capacity. Now let’s look at some ways to avoid these mistakes.

The Rule of 10

Construction drawings for a piece of process equipment.

When scaling up your process, NEVER assume that a simple linear expansion of your process train will be sufficient. It is often the case that process scale up is non-linear. Using the Rule of 10 is one way of scaling up your process through a stepwise iterative approach. The Rule of 10 is best explained through an example: Say you are performing a bench-top extraction of a few grams and want to scale that up to a few thousand kilograms. Before jumping all the way to your final process scale, start by taking a smaller jump and only increase your bench-top process by a factor of 10 at a time. So, if you were happy and confident with your results at the tens of grams scale, perform the same process at the hundreds of grams scale, then the thousands of grams scale, tens of kilograms scale, and so forth until you have validated your process at the scale of operations you want to achieve. By using the Rule of 10 you can be assured that your process will achieve the same yields/results at larger and larger scales of operation.

Scaling up your process through an iterative approach allows you to identify process issues that otherwise would not have been identified. These can include (but by no means should be considered an exhaustive list) improper heat transfer as process vessels increase in size, the inability to maintain process parameters due to inadequately sized utilities and/or supporting infrastructure, and lower yields than expected even though previous iterations were successful. However, this type of approach can be expensive, especially when considering custom process equipment, and not every processor in the cannabis/hemp space is going to be in the position to use tools like the Rule of 10 and instead must rely on claims made by the equipment vendor or manufacture when scaling up their process.

The Cannabis/Hemp Specific Process Equipment Trap

How many times have you heard this one before: “We have a piece of process equipment tailor-made to perform X,Y,Z task.”? If you have been around as long as I have in the cannabis/hemp space, probably quite a few times. A huge red flag when considering equipment for your expansion project!

Unless the equipment manufacturer is directly working with cannabis/hemp raw materials, or with partners who process these items, during product development, there is no way they could have verified the equipment will work for its purported use.

GMP compliant phytocannabinoid processing facility underconstruction.

A good example of this are ethanol evaporation systems. Most manufacturers of evaporators do not work with the volumes of ethanol they claim their systems can recover. So how did they come up with the evaporation rate? Short answer – Thermodynamics, Heat Transfer, and Fluid Mechanics. They modeled it. This much surface area, plus this much heat/energy, with this much pressure (or lack thereof), using this type of fluid, moving through this type of material, at this rate of speed, gets you a 1000-gal/hr evaporator or some other theoretical value. But what is the real rate once an ethanol and cannabis/hemp solution is running through the system?

For a straight ethanol system, the theoretical models and experimental models are pretty similar – namely because humans like alcohol – extensive real-world data for ethanol systems exist for reference in designing ethanol evaporators (more accurately described as distillation systems, i.e. stills). The same cannot be said for ethanol and cannabis/hemp extract systems. While it is true that many botanical and ethanol systems have been modeled, both theoretically and experimentally, due to prohibition, data for cannabis/hemp and ethanol systems are lacking and the data that do exist are primarily limited to bench-top and laboratory scale scenarios.

So, will that 1000-gal/hr evaporator hit 1000-gal/hr once it is running under load? That’s the real question and why utilizing equipment with established performance qualifications is critical to a successful process scale up when having to rely on the claims of a vendor or equipment manufacturer. Except this is yet another “catch 22”, since the installation, operational, and performance qualification process is an expensive endeavor only a few equipment manufacturers servicing the cannabis/hemp market have done. I am not saying there aren’t any reputable equipment vendors out there; there are, but always ask for data validating their claims and perform a vendor qualification before you drop seven figures on a piece of process equipment on the word of a salesperson.

Important Takeaways

Improper design and insufficient data regarding process efficiencies on larger and larger scales of manufacturing can lead to costly mistakes which can prevent projects from ever getting off the ground.

Each aspect of the manufacturing process must be considered individually when scaling your process train because each element will contribute to the system’s output, either in a limiting or expansive capacity.

I go further into this topic in my presentation: Challenges with Process Scale Up in the Cannabis/Hemp Industry, later this month during Cannabis Industry Journal’s Extraction Virtual Conference on June 29th, 2021. Here I will provide real-world examples of the consequences of improper process scale up and the significance of equipment specifications, certifications, and inspections, and the importance of vendor qualifications and the true cost of improper design specifications. I hope to see you all there.

Until then. Live long and process.

Five Things Every Cannabis Business Needs Before They Open

By Tim Allen
No Comments

When it comes to small business opportunities these days, few phrases give people the old dollar-sign-eyes more than “legal cannabis”.

From states like Michigan where it’s been approved for both medicinal and adult use, to places like South Carolina where legalization has been a popular topic for ballots and voters, cannabis is slowly turning into one of America’s biggest businesses.

You don’t need us to tell you that – Investopedia reports that (as of Nov. 2020) over 340,000 American jobs were devoted to the handling of plants at various stages along the retail cycle, and the industry was estimated at over $13 billion as of 2019.

Not bad for a plant that’s still technically illegal under federal law, huh?

If you’ve read this far, it probably means you’re hoping to be among the lucky ones who can strike it rich with their own cannabis business. A noble undertaking, but are you really prepared to make your mark? In a field as competitive – and occasionally complicated – as cannabis can be, you really need to lead with your best foot forward, and make sure you’re as well prepared for the various challenges of a fairly new industry as possible.

With that in mind, below is a list of the five things you’ll need to double-check and make sure you actually have access to before embarking on your new business venture.

The right shelving & equipment

You see this a lot with smaller businesses as well as, er, ‘independent growers’. A lot of people assume that they can just buy some greenhouse shelves, line the walls of their business with it, and call it a day, right?

Offering rare or unique cannabis strains is a great way to differentiate

This approach leads to problems more often than not. Even above and beyond the inherent concerns of helping your plants grow safely (and productively!), the sort of equipment you use should reflect the sort of business you’re trying to run. A cannabis retail outlet, for example, is going to need different sorts of shelves and tables than a dispensary or growing facility, as the work being done is completely different.

It will take a little research, but it helps that a lot of businesses these days are starting to offer shelving specifically designed for various cannabis operations. Check to see if any of the big warehouse suppliers near you have gotten into the cannabis game yet – Shelving Inc, Metro, and Rack & Shelf are a few of the bigger shelving names with cannabis offerings as of this writing.

Strong branding

Long gone are the days when all you needed to be successful in cannabis was a booth at the shady flea market, a pun name and a big sign that said “Head Shop” to throw off the authorities.

Far too many cannabis businesses launch themselves headlong into a business plan without stopping to think of a good name, or just settling for the first one they think of. With as crowded as the playing field is quickly becoming, it might honestly be worth it to pay someone to help you come up with a decent logo and branding – it’ll go a long way towards helping you stand out against everyone else using a green font. Places online like High Hopes specifically offer these services for cannabis businesses, so you know they’ll be able to figure out what you’re about more quickly.

An understanding of your consumer base

The exact sort of work your cannabis business performs is going to affect what your potential customer base can be – and vice versa.

Brands are embracing contemporary design more and more

Early on in the planning stages, make sure to figure out exactly who you’re going to sell your products to, as this will inform nearly every other decision your business makes. Do you want to sell directly to the customer, or to work as a distributor for CBD/cannabis retail outlets? Are you prepared to manage and run your own storefront, or are you just going to rent warehousing space to sell your plants to other retailers? If so, do you know who the businesses are in your area that you could work with? Or, if you are planning on entering the retail space, do you know how many other cannabis businesses could be operating in your desired geographical area? Finding an audience may be the hardest part of opening any business, but it’s important work.

Banking that understands your industry

Maybe the biggest drawback to being involved in an industry as comparatively new as cannabis, is that a lot of the old methods of doing business aren’t quite available to you. Many financial institutions of various sizes are limited in the ways they can help finance cannabis businesses, from not understanding the regulations and needs of your industry, all the way to being unable to assist cannabis businesses with banking in the first place.

Finding the right banking services can be challenging

It might be advantageous to look into banks, credit unions or financing companies in your area that specifically offer banking services (like business accounts and the like). A few examples include Aery Group from New Mexico, or Seed to Sale in Michigan. (It’s important to note that many of these companies, such as Aery Group, can only service the state they’re located in due to different state-by-state regulations – check ahead to make sure you find a place that can help you!)

Knowledge of the needed licensing and regulatory requirements

Getting a license to open any business is a tricky prospect on a good day, but for an industry as wide-ranging and varied as cannabis, getting licensed can require a lot of homework.

Even if you’re lucky enough to be setting up shop in a state that allows for the sale of cannabis, the licensing process can vary widely from state-to-state. In New Mexico, for example, it can take months to acquire a license simply due to the amount of paperwork, research and submissions required to cement your business. Before going too far down the rabbit hole of opening your business, make sure to take the time you need to completely research and understand the various local and state regulations you’ll need to adhere to for your business to get off the ground.

Obviously, there’s going to be a lot of other hurdles and requirements that come with starting a business – but by remembering these five things, you’ll be off to a much better start than many others.

Implement These Tips to Quickly Fortify Cannabis Dispensaries

By Heather Bender
No Comments

Based on the recent string of cannabis thefts in Portland, Oregon, the spotlight is shining even brighter on the need for enhanced security measures at cannabis dispensaries throughout the country. According to the Oregon Liquor Control Commission, the Portland metro area alone has experienced more than 120 cannabis shop burglaries since March 2020, resulting in a reported total loss of more than $500,000 in cash and products.

Robbing a cannabis dispensary is as lucrative as robbing a bank. Cash is king in the shops until the Secure and Fair Enforcement (SAFE) Banking Act is passed to prohibit federal banking regulators from penalizing depository institutions that provide banking services to legitimate cannabis businesses. Until the Act is passed, it is widely known that all transactions must be done in cash—which makes cannabis dispensaries a prime target for thieves.

Dispensaries are prime targets for burglary. Defending your storefront requires a comprehensive security plan.

While many security protocols—such as product traceability systems and security cameras—are mandated by each individual state, dispensary owners should take measures to actively secure their product, protect their employees and preserve their businesses as theft increases.

One of the quickest and most cost-effective ways to fortify shop security is by implementing rolling security doors. After determining what level of security is needed, consider these four tips to help deter criminal activity and ensure the safety of both employees and products.

Tip 1 – Defend The Storefront
Designed to prevent against looting events and burglaries, heavy-duty rolling steel doors offer cannabis business owners robust security. They can be retrofitted into existing buildings, are exterior mounted and are ideal for storefront defense—including protecting glass windows, which can be expensive to replace. Unlike more common rolling grilles, thieves can’t see merchandise when the rolling door is lowered. In addition to the door giving the building a secure look, blocking sight access is key to deterring criminals.

Heavy-duty steel doors must also be lift- and pry-resistant. Manufacturers put the doors through rigorous testing, and some security doors even meet Department of Defense forced entry standards, which can provide up to an hour of protection against violent attacks against the door to gain entry. Look for rolling security doors that can withstand heavy impact and resist pry attempts with common tools, as well as doors that are lift resistant. Some manufacturers offer doors with robust slide locks and rigid heavy-duty bottom bars, enabling the doors to withstand up to 4,500 lbs of lifting effort.

Tip 2 – Protect While Allowing Visibility and Airflow
If product visibility is desired, but more robust security is needed at the storefront—beyond a security measure such as impact glass—a heavy-duty security grille is an excellent choice. Security grilles are easy to custom order and don’t require structural modifications to fit individual spaces. They are easily installed behind storefront glass, are compact enough to remain out of sight when not in use and require little maintenance.

Strong rolling service doors can protect delivery entrances well

It’s important to work with a manufacturer to select a rolling grille that provides dependable, increased security. Choose grille curtains with rods that are spaced closer together and have heavier links. Security grilles with these features are harder to lift and pry than standard rolling grilles.

Rolling security grilles are also an ideal solution to protect counters inside the dispensary. They can be easily concealed in small headspaces where there is limited ceiling room.

Tip 3 – Fortify A Store Within A Store
For cannabis dispensaries located within high-end retail shops, it is important to consider additional security measures to separate the dispensary from the rest of the store.

A metal grille can be a good barrier for a store within store

A store within a store may be subject to different hours of operation as states often dictate specific operating hours for cannabis dispensaries. Altered operating hours necessitate an easy way to secure only a small section of a larger store.

If aesthetics are of concern inside retail shops, a woven metal mesh grille will provide both beauty and security without imposing looks while securing cannabis products as customers browse throughout the store. Manufacturers offer a variety of patterns and even logo designs as a way to bring more creativity to a grille’s aesthetics—making them rolling pieces of art.

Tip 4 – Secure Deliverables
Dispensary owners sometimes overlook the fact that thieves target deliveries. Deliveries that are made at the back of the store or in receiving areas may be the most at risk. It is of utmost importance to be aware of how deliveries are timed, who is present during them, and how the product is handed off.

Robust rolling service doors provide the best security for delivery entrances and are more secure than traditional rolling sectional doors. Made from slats of formed galvanized steel, aluminum or stainless steel, these rolling doors are completely customizable to meet existing building designs and are ideal for areas with limited overhead room.

Robust Protection
By closely evaluating the levels of security needed, the layout of the building and where deliveries take place, security updates and enhancements are easily implemented with the right rolling doors. Every door is made for a specific opening, so each one is custom-made for its application. Choose a knowledgeable manufacturer that will help determine which rolling closure suits the dispensary’s needs.

Cannabis Property Coverage: Understanding Risk Management & Communication

By Bradley Rutt
No Comments
Cannabis Industry Journal

For cannabis companies, property coverage can cost as much as seven to 10 times what traditional manufacturing and retail outlets pay. That is, of course, because of the inherent hazards involved in manufacturing and selling cannabis, in a difficult insurance market.

For landlords and building owners, taking in a cannabis tenant can be tricky as well. Because of the higher theft and manufacturing risks, many underwriters are unwilling to offer coverage. And, failure by a landlord to disclose a cannabis tenant is likely to result in a denied claim. Keeping property coverage in check by implementing risk management best practices and working to expand coverage and reduce premium costs can propel a cannabis business even further.  

Moreover, some landlords and building owners will require businesses to maintain occurrence-based liability coverage, which is harder to secure when running a cannabis operation. An occurrence-based liability policy is one that covers the renter for an accident occurring during the policy period, regardless of when a claim is made.

Instead, some insurance companies will only cover cannabis business’ high risks with a claims-made policy, or one in which claims must be made during the policy period only. Landlords will often stipulate their requirement for an occurrence-based policy in their lease. That means that cannabis businesses with a claims-made policy could unknowingly be in violation of their lease.

These issues and others have allowed landlords to command premium rent from cannabis business owners who find obtaining the right property coverage difficult.

To calm the rising tide of rent and property coverage costs, cannabis business owners and operators can engage in the following risk management considerations.

 Risk Management Considerations for Facilities with a Cannabis Operation 

Carriers are more likely to provide a policy to cannabis businesses that are doing what they can to minimize their risk. Here are six ways cannabis businesses can reduce their costs, minimize exclusions and obtain broader property coverage.

  1. If you are a retailer, have a plan to prevent or respond in the event of a robbery.
  2. Install and know how to use vaults and safes properly.
  3. Install central station alarms, cameras and other safeguards. Have them tied to your phone for easy access.
  4. Depending on the nature of the operations, install and regularly test fire sprinklers on site to make sure they are in working order.
  5. Consider hiring a third party, properly-insured, armed guard to safeguard your storefront on a regular basis.
  6. Institute industry-known best practices for high-risk manufacturing processes, like oil extraction.

Insurance Considerations for Facilities with a Cannabis Operation 

Risk management is critical to controlling risk, and insurance considerations can help your cannabis business obtain broader coverage and reduce premium costs.

  1. Communicate with your insurance broker.If you’re a landlord and you want to rent to a cannabis tenant, have a conversation with your insurance carrier at least 30 days before the lease begins. Even if you do, there’s a good chance that your carrier will issue a notice of cancellation (NOC) because they don’t want to engage with cannabis risk. On the other hand, if you don’t disclose the new tenant risk, should a claim be filed, it will could be denied, and the non-disclosure could cost you your policy.
  2. Engage a broker/carrier that specializes in cannabis.In such a volatile market, it is important to work with a broker and carrier that specialize in cannabis. This will enable hidden exclusions to be removed and help you procure the best policy and pricing possible for your organization.
  3. Tell your insurance “story.”Let the carrier understand your business and its risks by telling them your “story.” Tell them what your business does well, including current risk management practices and how you’ve been able to reduce claims. This will go a long way toward potentially minimizing premium costs and exclusions and obtaining broader coverage.
  4. Get another set of eyes. Most carriers will require a lengthy application from cannabis businesses in which the carrier may require the business to comply with certain requirements like having an approved safe or vault room. Your business will be held to the requirements stipulated in the application should you sign and submit it. Ask your broker or a reliable attorney to review the contract for anything you may have missed. Some carriers will incorporate the submitted application into the policy. Any changes between policy inception and a claim could cause coverage issues.

The fast-growing nature of the cannabis industry has ushered in a new set of challenges for business owners and operators. Keeping property coverage in check by implementing risk management best practices and working to expand coverage and reduce premium costs can propel a cannabis business even further.

Why Europe May Serve as an Important Bellwether for Hempcrete Use in the United States

By Stephanie McGraw
No Comments
european union states

Hemp-based construction materials are an attractive option for achieving environmentally friendly goals in construction, including reduced emissions and conservation of natural resources. Hemp construction materials dating back to the 6th Century have been discovered in France and it has long been eyed with interest by hemp growers and manufacturers, as well as environmentalists in the United States and abroad. As the European Union moves forward with its 2019 European Green Deal, United States hemp, construction and limestone industries, as well as regulatory agencies, will be provided with an important preview of the benefits, risks and issues arising out of the use of hemp in construction.

The European Green Deal and Circular Economy Action Plan

Hemp applications in construction are gaining increased interest as the EU seeks to neutralize its greenhouse gas emissions by 2050. Much of the specifics for this transition to zero emissions are outlined in the EU’s “A New Circular Economy Action Plan,” announced on March 11, 2020. According to the EU, “This Circular Economy Action Plan provides a future-oriented agenda for achieving a cleaner and more competitive Europe in co-creation with economic actors, consumers, citizens and civil society organisations.” The plan aims at accelerating the transformational change required by the European Green Deal and tackles emissions and sustainability issues across a number of industries and products, including construction.

Construction in the EU accounts for approximately 50% of all extracted natural resources and more than 35% of the EU’s total waste generation. According to the plan, greenhouse gas emissions from material extraction, manufacturing of construction products and construction and renovation of buildings are estimated at 5-12% of total national greenhouse gas emissions. It is estimated that greater material efficiency could save 80% of those emissions. To achieve those savings, the plan announces various efforts to address sustainability, improve durability and increase energy efficiency of construction materials.

How Hemp Could Help Europe Achieve Neutral Emissions

Hemp, and specifically hempcrete, is being eyed with heightened interest as the EU enacts its plan. Indeed, recent mergers and acquisitions in the European hemp industry signal just how attractive this hemp-based product may be as international, national and local green initiatives gain momentum. But how would hemp be utilized in construction and what types of legal issues will this industry face as it expands?

Image: National Hemp Association

The primary hemp-based construction material is “hempcrete.” Hempcrete is typically composed of hemp hurds (the center of the hemp plant’s stalk), water and lime (powdered limestone). These materials are mixed into a slurry. The slurry petrifies the hemp and the mixture turns into stone once it cures. Some applications mix other, traditional construction materials with the hempcrete. The material can be applied like stucco or turned into bricks. According to the National Hemp Association, hempcrete is non-toxic, does not release gaseous materials into the atmosphere, is mold-resistant, is fire– and pest-resistant, is energy-efficient and sustainable. To that last point, hemp, which is ready for harvest after approximately four months, provides clear advantages over modern construction materials, which are either mined or harvested from old forests. Furthermore, the use of lime instead of cement reduces the CO2 emissions of construction by about 80%.

Watching Europe with an Eye on Regulation and Liability Risks

Hempcrete indeed sounds like a wünder-product for the construction industry (and the hemp industry). Unfortunately, while it may alleviate some of the negative environmental impacts of the construction sector, it will not alleviate the threat of litigation in this industry, particularly in the litigious United States. The European Union’s experience with it will provide important insights for U.S. industries.

Hempcrete blocks being used in construction

Because hemp was only recently legalized in the United States with the passage of the 2018 Farm Bill, it is not included in mainstream building codes in the United States, the International Residential Code, nor the International Building Code. Fortunately, there are pathways for the consideration and use of non-traditional materials, like hempcrete, in building codes. However, construction applications of any form of hemp, including hempcrete, at this point would likely require extensive discussions with local building authorities and an application showing that the performance criteria for the building are satisfied by the material. Such criteria would include standards and testing relating to structural performance, thermal performance, and fire resistance. Importantly, the ASTM does have a subcommittee working on various performance standards for hemp in construction applications. European progress on this front would pave an important regulatory pathway for the United States, as well as provide base-line standards for evaluating hempcrete materials.

Insights into regulation and performance standards are not the only reason to watch the EU construction industry in the coming decades. Introduction of hempcrete and hemp-based building materials in the United States will likely stoke litigation surrounding these materials. Although there is no novel way to avoid the most common causes of construction litigation, including breach of contract, quality of construction, delays, non-payment and personal injury, the lessons learned in Europe could provide risk management and best-practice guidance for the U.S. industry. Of particular concern for the hemp industry should be the potential for product liability, warranty, and consumer protection litigation in the United States. The European experience with hempcrete’s structural performance, energy efficiency, mold-, pest- and fire-resistant properties will be informative, not just for the industry, but also for plaintiff attorneys. Ensuring that hempcrete has been tested appropriately and meets industry gold-standards will be paramount for the defense of such litigation and EU practices will be instructive.

The United States construction industry, and particularly hempcrete product manufacturers, should pay close attention as the EU expands green construction practices, including the use of hempcrete. The trials and errors of European industry counterparts will inform U.S. regulations, litigation and risk management best practices.

 

Priorities During the Pandemic: How to Run a Lab Under COVID-19

By Dr. Peter Krause, Udo Lampe
No Comments

During the COVID-19 pandemic, most testing laboratories have been classified as relevant for the system or as carrying out essential activities for national governments. Therefore, it is crucial to maintain activities and optimally assess the changes that are occurring, framed within the spread of the SARS-CoV-2 virus. Analytica Alimentaria GmbH, a testing laboratory with its headquarters in Berlin, Germany and a branch office in Almeria, Spain, decided to focus its management on the analysis of events and the options available, at the legal and employment level, to ensure continuity of activities and reducing, as much as possible, the damage for the parties involved: employees and company. Accredited by the International Accreditation Service (IAS) to ISO/IEC 17025:2017, Analytica Alimentaria GmbH is required to implement risk-based thinking to identify, assess and treat risks and opportunities for the laboratory. Since March 12, 2020 a crisis committee was established, formed by the six members of the company’s management, covering general management, human resources, direction of production, finance and IT. The committee meets every day and it intends to:

  • Minimize the risks of contagion
  • Be able to continue providing the service required by our clients
  • ensure that the company as a whole will survive the economic impact of the crisis
  • Take measures that are within the legality of both countries where the laboratory operates (Spain and Germany),
  • Manage internal and external communication related to the crisis

To achieve correct decision making, daily meetings of the committee were established, to review the situations that were presented day after day and the actions that should be carried out. Each decision was analysed in a prioritized, objective, collaborative and global way.

The basis of the lab’s action plan was a well-developed risk assessment. In addition to the risk of getting a droplet or smear/contact infection with the coronavirus SARS-CoV-2 (risk I) by contact with other people, psychological stress caused by changing working conditions (home office), contact options and information channels were also identified (risk II).

As a result of the risk assessment, the conclusion was that a mix of various measures is the best form of prevention:

  • Keep distance
  • Avoid “super spreader” events
  • Personal hygiene
  • Regular communication between managers and personnel about the current situation and possible scenarios

The risk assessment took both areas into account. The following assessment was developed together with an external specialist and focused on risk I:

Risk I Assessment Protective measures / hygiene plan
Organisation
Working hours and break arrangements High Limit the gathering of people and ensure a minimum distance:

  • Relocated work, break and mealtimes
  • Create fixed groups of shift-working staff
  • Time gap of 20 min. between the shifts
  • Enable home office wherever it is possible
Third party access Moderate Few but “well-known” visitors:

  • Reduce the number of visits and keep internal contacts to a minimum
  • Ensure the contact chain
  • Inform visitors about the internal rules and obtain written consent
Dealing with

suspected cases

High Isolation and immediate leave of the company:

  • Contactless fever measurement (in case of typical symptoms)
  • Leave the company or stay at home
  • If the infection is confirmed, find contact persons (including customers or visitors) and inform them about a possible risk of infection
Contact with other persons
Traffic route from home to work Moderate Avoid public transportation:

  • Take a car, bicycle or go by foot
  • Enable mobile work and teleworking
At work High Always keep a sufficient distance of 2.0 m from people:

  • If minimum distances cannot be maintained, wear protective masks or install physical barriers (acrylic glass)
  • Organize traffic routes so that minimum distances can be maintained (one-way routes, floor markings indicating a distance of 2 m)
  • Use digital meetings instead of physical ones
Sanitary facilities Moderate Remove virus-loaded droplet as often as possible:

  • Provide skin-friendly liquid soaps and towel dispensers
  • Shorten or intensify cleaning intervals
  • Hang out instructions for washing hands at the sink
  • Include instructions for proper hand-disinfection
Canteens, tea kitchens and break rooms High One person per 10 m² = minimum:

  • Reduce the number of chairs per table
  • Informative signs in every room, indicating the maximum number of permitted persons
Ventilation High Diluting or removing bioaerosols (1 µm virus-droplets):

  • Leave as many doors open as possible
  • Regular and documented shock ventilation every 30 minutes or more frequently, depending on the size of window
  • Operate ventilation and air-conditioning systems, since the transmission risk is classified as low here
Use of work equipment Moderate Use tools and work equipment for personal use:

  • Regular cleaning with changing use (PC, hand tools, coffee machine, …)
  • If possible, use gloves when using equipment for a larger number of users
Protective masks Moderate
  • Use of protective masks as an additional measure, indicating that this does not replace keeping distance
  • Recommend wearing masks in commonly used areas and explain that they do not protect yourself, but help to protect others
  • Give clear instructions (written and oral) on how to use a mask correctly and explain the use and purpose of different mask-types
  • Distribute masks freely

A number of guidelines and concrete measures addressing the risks related to health issues are already in place. Those health issues in risk group II are more closely related to the psychological effects of the crisis, however, are also more complex to mitigate. The key strategy is communication and, in particular, actively listening to all employees of the company.

Analytica’s robust company culture, based on values established in coordination with the whole staff, has been of significant help during the crisis. The some 150 staff members are organized by over 22 team coordinators. During the crisis, active communication has been intensified significantly. The crisis management team set up regular alignment meetings with all the coordinators and with individual persons with particular situations. This way, not only was it possible to explain the development of the crisis and the subsequent measures, the conversations with coordinators were also the most important source of information enabling the appropriate decisions. The coordinators, closely aligned and in sync with management, were then able to communicate with their team members with a high degree of confidence. One outcome of the communication was a measure that proved very effective in fortifying trust within the company: all measures and evaluations, as well as a chronological review, are published in a dynamic internal report and are made available, with full transparency, to all staff members. Besides the many individual and group alignment meetings (usually held by video conference), this has been a key measure to establish confidence and security within the company.

On the other hand, the company made a great effort to balance the effect of the general closure of kindergartens and schools in Spain and Germany. Each case where staff members were required to care for children at home was studied individually and agreements were established, adapting shifts and making use of time accounts, to allow childcare at home without significant loss of income.

The success of the measures is shown by the continuous work of both laboratories during the crisis. Besides the personal tragedy of a possible infection, the identified risk to the company has the consequence of a (partial) quarantine due to an infected person in contact with the staff and the consequent loss of work-power which might lead, in extreme cases, to a closure of the laboratory. According to the governmental regulation in Germany, if an infection occurs (confirmed by the health department), contact persons cat. 1 (more than 15 min. contact face to face) are identified and sent to quarantine. Other contact persons, e.g. contact persons cat. 2 (same room without face to face) must be identified quickly with the collaboration of the infected person and notified and, if necessary, sent in quarantine. In this case, there is a confirmed emergency plan that maintains the laboratory’s ability to work, defining replacements and alternative work-flow strategies.

It has been part of our strategy to validate all our measures with the relevant guidance documents made available by the official competent institutions. The German Federal Office for Public Safety and Civil Protection (Bundesamt für Bevölkerungsschutz und Katastrophenhilfe) has published a guide, “Crisis Management in Companies, 9-point Checklist” especially for critical infrastructure companies in the CoVid-19 crisis.

Having been classified as a core business enterprise (Spain) and “relevant to the system” (Germany), we consider it important to use them as a reference to confirm our level of alignment with your proposal for crisis management.

An important effect, relevant to any leader in times of crisis, is that the confirmation of all points of such a checklist provides certain peace of mind regarding the question: Have we done everything we could?

HACCP

HACCP for Cannabis: A Guide for Developing a Plan

By Radojka Barycki

HACCP

Hazard Analysis and Critical Control Points (HACCP) is a systematic approach that evaluates hazards that may potentially be present in food products that can harm the consumer. The process used to manufacture the product is evaluated from raw material procurement, receiving and handling, to manufacturing, distribution and consumption of the finished product1. The documented process is what is known as HACCP plan. Although HACCP was designed to evaluate hazards in foods, it can be used to assess or evaluate hazards that may potentially be present in cannabis consumable products (edibles and vaping) that can cause harm to the consumer.

HACCP plan development requires a systematic approach that covers 5 preliminary steps and 7 principles. A systematic approach means that each step must be followed as outlined. Skipping a step will result in a HACCP plan that most likely will be ineffective to control potential hazards in the product.

The 5 preliminary steps are:

  1. Establish a HACCP team
  2. Describe the product
  3. Establish the intended use of the product
  4. Develop a flow diagram
  5. Verify the flow diagram

The 7 Principles are:HACCP

  1. Conduct a hazard analysis
  2. Identify the critical control points (CCPs)
  3. Establish critical limits (CL)
  4. Establish monitoring procedures
  5. Establish corrective actions
  6. Establish verification procedures
  7. Establish records and record keeping procedures1,2

It is important to mention that HACCP plans are supported by programs and procedures that establish the minimum operational and sanitary conditions to manufacture safe products. These programs and procedures are known as pre-requisite programs (PRP) or preventative controls1,2.

Figure 1. Flow Diagram

A multidisciplinary team must be established in order to ensure that all inputs of the product manufacturing process are considered during the hazards analysis discussions. The description of the product and its intended use provides detail information on ingredients, primary packaging material, methods of distribution, chemical characteristics, labeling and if any consumer might be vulnerable to the consumption of the product. A verified flow diagram is an accurate representation of the different steps followed during the product manufacturing process and will be used to conduct a hazard analysis. An inaccurate flow diagram will set the stage for an inadequate HACCP plan. Therefore, it is important that the HACCP team members verify the flow diagram. Figure 1 is a flow diagram for a fictional infused apple juice manufacturing plan that I will be using as an example.

The hazard analysis is the backbone of the HACCP plan. There are two elements that must be considered when conducting the hazard analysis:

  • Identification of the hazard associated with the ingredient(s) and/or the product manufacturing steps. These hazards have been categorized as: Biological, chemical (including radiological) and physical. Biological, chemical and physical hazards should be considered for each ingredient, primary packaging and process step. Also, it is important that the team is specific as to what hazard they are referring to. I often find that biological hazards are identified as “pathogens” for example. The team has to be specific on which pathogen is of concern. For example, if you are processing apple juice, the pathogens of concern are pathogenic coli and Salmonella sp. However, if you are processing carrot juice, you need to add Clostridium botulinum as a biological hazard also. If the choice of method to eliminate the hazards is pasteurization for example, the processing temperature-time combinations will differ greatly when manufacturing the apple juice vs. the carrot juice as C. botulinum is an organism that can sporulate and, therefore, is harder to kill.
  • Characterization of the hazard. This implies determining the significance of the potential hazard based on the severity of the consequence if it is consumed and the likelihood of occurrence in the ingredient or process step. Only steps in the process that has significant hazards should be considered further.
Table 1. Ingredient Hazard Analysis

In my professional experience, the hazard analysis is one of the most difficult steps to achieve because it requires the expertise of the multidisciplinary team and a lot of discussion to get to the conclusion of which hazard is significant. I find that a lot of teams get overwhelmed during this process because they consider that everything in the process may represent a hazard. So, when I am working with clients or providing training, I remind everyone that, in the bigger scheme of things, we can get stricken by a lighting in the middle of a thunderstorm. However, what will increase our chances would be whether we are close or not to a body of water for example. If I am swimming in the middle of a lake, I increase my chances to get stricken by the lighting. In comparison, if I am just sitting in my living room drinking a cup of coffee during the thunderstorm, the likelihood of being stricken by a lighting is a lot less. The same rationale should be applied when conducting the hazard analysis for manufactured products. You may have a hazard that will cause illness or death (high on the severity chart) but you also may have a program that mitigates the likelihood of introducing or having the hazard. The program will reduce the significance of the hazard to a level that may not need a critical control point to minimize or eliminate it.

Table 2. Process Hazard Analysis (1)

Clear as mud, right? So, how would this look like on the infused apple juice example? Table 1 shows the hazard analysis for the ingredients. Tables 2 and 3 show the hazard analysis for the part of the process. In addition, I have identified the CCPs: Patulin testing and pasteurization. There is a tool called the CCP decision tree that is often used to determine the CCPs in the process.

Once we have the CCPs, we need to establish the critical limits to ensure that the hazard is controlled. These limits must be validated. In the case of Patulin, the FDA has done several studies and has established 50 ppm as the maximum limit. In the case of pasteurization, a validation study can be conducted in the juice by a 3rd party laboratory. These studies typically are called thermal death studies (TDS) and provide the temperature and time combination to achieve the reduction of the pathogen(s) of concern to an acceptable level that they do not cause harm. In juice, the regulatory requirement is a 5-log reduction. So, let’s say that the TDS conducted in the infused apple juice determined that 165°F for 5 seconds is the critical limit for pasteurization. Note that the 5 seconds will be provided by the flow of the product through the holding tube of the pasteurizer. This is measured based on flow in gallons per minute.

Monitoring is essential to ensure that the critical limits are met. A monitoring plan that outlines what, how, when and who is responsible for the monitoring is required.

Ideally, the system should not fail. However, in a manufacturing environment, failures can happen. Therefore, it is important to pre-establish steps that will be taken to ensure that the product is not out of the control of the facility in the event of a deviation from the HACCP plan. These steps are called corrective actions and must be verified once they are completed. Corrective actions procedures must address the control of the product, investigation of the event, corrective actions taken so the deviation doesn’t reoccur and product disposition.

Table 4. HACCP Plan Summary

Verification activities ensure that the HACCP plan is being followed as written. Typically, verification is done by reviewing the records associated with the plan. These records include but are not limited to monitoring records, calibration records, corrective action records, and preventive maintenance records for equipment associated with the CCPs. Record review must be done within 7 working days of the record being produced.

Finally, establishing records and record keeping procedures is the last step on developing HACCP plans. Records must be kept in a dry and secure location.
