Process Scale UP in the Cannabis/Hemp Industry
Darwin Millard, Committee Vice Chair, ASTM International
Darwin Millard provides 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.
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.
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.
Environmentally conscious manufacturing has never been more important; for the survival of both the planet and your business. The internet makes CBD product comparisons quick and efficient, so consumers can interrogate every aspect of your product and processes before deciding to make a purchase. Sustainability credentials are now a primary decision making factor for your customers.
Water jacketed vessels are a cost-effective way of achieving more consistent blends than is possible manually
For business of all sizes, improving resource use and efficiency is a great place to start. This will reduce waste and improve your environmental impact, and has the added benefit of improving your return on investment!
I always recommend investing in stainless steel equipment for manufacturing and distributing CBD oils. Stainless steel is one of the most environmentally efficient raw materials, because of its durability and ability to be recycled. Vessels last an extremely long time, and even once their service life is over, they should never enter the waste stream. Many of our US customers transport their CBD products around the world in stainless steel vessels, which can then either be shipped back for re-use, or re-used at the recipient site.
In terms of finding your ideal equipment supplier, those who have won awards for their environmental initiatives are the cream of the crop; they can be a real asset to your business and will often collaborate on sustainability-themed social content, which is really valuable to get in front of your customers.
Once you’ve investigated the credentials of suitable suppliers, how do you make sure their blending equipment will perfectly meet your needs?
Here are my recommended four points for consideration:
Adding Toggle Clamps keeps your products airtight and reduces the chance of contamination in transit
Vessel Capacity: Vessel capacity must be considered in two ways; maximum and minimum working capacity. Standard vessels have their capacity listed as ‘brim full’ – suppliers tell you the total overall volume of space in the vessel. However, maximum capacity must allow for 10-20% free space below ‘brim full’, so that if product is being mixed and stirred, there is no overspill. For example; to blend 75L batches of CBD oil, it’s generally recommended to purchase a 100L mixing vessel.
Vessel Bottom Shape: Standard vessels have flat bottoms, which makes it difficult to drain them to completely empty. An experienced supplier such as Pharma Hygiene Products has the capability to modify standard vessels, to include a sloped bottom at 3 degrees, which reduces leftover product pooling when draining your oils. Vessels can also be custom-made with a cone or dish shaped bottom, whereby a valve can be positioned in the centre of the base to allow full draining, to reduce waste and increase profitability.
Stainless Steel Grade: Stainless steel blending vessels for CBD oils are generally offered in 304 or 316L pharmaceutical-grade material. A simple description of the difference is that 316L grade contains an extra 2% molybdenum, for additional corrosion-resistance. Increased regional and international legislation concerning CBD products has come hand-in-hand with tighter interrogation of hygiene practices. Contaminant-free materials such as stainless steel are ideal to ensure international pharma-quality compliance for your business’ blending processes. Critically, at Pharma Hygiene Products a comprehensive range of compliance certification is available to confirm the grade of material, to prove surface smoothness, and to guarantee that no cross-contamination from BSE or CJD diseases occurs.
Lastly, don’t forget to let your supplier know in advance if you have any special requirements for your product or vessel. Some common examples include:
Temperature control – Adding a water jacket to your vessel is a simple solution for heating, cooling or maintaining the temperature of your product as it blends.
Toggles and seals – For airtight, contaminant-free transportation.
Viewing holes – For easy visual inspection whilst blending.
Your equipment supplier can be a real financial and reputational asset, so be sure to do your homework before making an investment!
Commercial real estate took a dive last year as companies began to work from home, but changing regulatory environments have opened doors to a new industry in need of property: cannabis. Growing rapidly at both the medical and adult use levels, cannabis businesses have been eager to move into vacant buildings, quickly buying up space as more states adjust their laws regarding cannabis.
Cannabis businesses cannot go at it blindly, however. Legal cannabis firms of all sizes – from the smallest startup to the biggest enterprise – will face regulatory challenges, traceability requirements, process control standards and, ultimately, the right technology to keep them moving forward in this promising industry.
Use data to keep track of plants, patients and regulations
As a highly regulated industry, cannabis companies could be investigated at any time. Regulatory authorities may, at the very least, request proof that they are compliant with state restrictions. Cannabis enterprises will only be able to quickly and easily provide that proof if they have immediate access to accurate historical data. With that information, they can generate the necessary reports at a moment’s notice and maintain a reliable audit trail.
Cultivation is where the tracking process begins.
Historical data is also useful for both growers looking to evaluate why certain plants are more successful than others and for sellers looking to improve their customer experience. By tracking everything from mother plants to clones, growers can build a strong genetics profile and gain a powerful competitive edge. Historical data also aids sellers, who can use it to enhance their digital storefronts and keep track of customer information, shopping history and other details that could improve the e-commerce experience.
In addition to customer details, sellers must also keep track of patient information when selling in a medical-only environment. Prescriptions need to be carefully managed to ensure that patients only receive products that they have been approved to purchase and use.
Utilize process control to foster scalable and repeatable processes
Process control is another vital component that every cannabis grower, manufacturer, processor and distributor must possess. They need scalable and repeatable processes to prevent steps from being bypassed, ensuring that every finished product matches the same high-quality standards. If there are no stopgaps in place, steps could be missed if employees are rushing to meet a deadline or simply think that a particular test or check isn’t needed. Those kinds of mistakes can be hugely detrimental to any cannabis company and may waste product, diminish profits and turn off customers.
A plant tagged with a barcode and date for tracking
Similarly, visibility and control over inventory is a top priority for any business, but it reigns supreme in the cannabis space. Managers should always, at all times, know where the product is as it moves throughout the warehouse, or risk costs and waste. By directly tying scanners and barcodes to the right technology, organizations can ensure that all product is accounted for and easily located using real-time data.
Build a foundation for scalability
Cannabis businesses don’t have the time to manually keep track of these aspects, and it wouldn’t even be possible as they grow and expand their operations. As they evolve, so too will the list of software requirements that are needed to operate smoothly, reliably and efficiently.
Cannabis processors have traditionally invested in seed-to-sale technology, relying on barcodes to track products throughout their lifecycle. While it is critical for cannabis enterprises to keep a strong level of control over lot tracking, this type of software is very limited. Cannabis firms would therefore be better served by an ERP solution with a single data source that provides centralized, real-time access to vital business information.
ERP technology can also help cannabis businesses better manage their production schedule, material requirements planning, accounting, purchasing, inventory management and document generation. The key, however, is to choose the right technology, avoiding ERP solutions that rely on customizations and bolt-ons, which will impede an organization’s ability to scale. Cannabis businesses should instead use technology that makes all of its features, enhancements and extensibility available to all customers, ensuring that every user has access to the same benefits.
Freya Farm, a pesticide-free cannabis producer and processor located in Conway, Wash., was recently forced to issue a recall after the chemical o-Phenylphenol, listed under CA Prop 65, was found on its products. Testing traced the antimicrobial compound, known to cause cancer, back to the FDA-compliant food grade gloves used by Freya during packaging.
The reason this could happen with FDA-compliant, food grade gloves needs urgent attention. The production and manufacturing of food contact gloves is largely unsupervised, with limited and infrequent checks on gloves imported into the US. After initial approvals, non-sterile, FDA-compliant food grade gloves are not subject to ongoing controls. This may lead to lower grade and cheap raw materials being used in sub-standard production facilities and processes.
Why “Food Safe” Gloves Aren’t Always Safe
The quality and safety of disposable gloves are limited to Letters of Compliance and Guarantee on the general make and model of the glove, not necessarily the glove you are holding in your hand. There are few controls on the consistency of raw materials, manufacturing processes and factory compliance for both food contact and medical examination grade gloves. Therefore, the opportunity exists for deliberate or accidental contamination within the process of which the Preventive Controls Qualified Individual (PCQI) may not be aware.
In the words of Freya Farm, “Nothing ruins your day like testing your product, confident it will be clean, only to find it contaminated with some crazy, toxic chemical.” In tracing the issue, the gloves were the last thing Freya Farm tested, as they never suspected something sold as food safe could be the culprit.
A recall of this type can be expensive, as fines range up to $200,000. Since this incident, Freya Farm has implemented a responsible sourcing policy for gloves using supplier Eagle Protect to protect its products, people and brand reputation.
Glove inspection includes five factors of quality controls
Eagle Protect, a global supplier of PPE to the food and medical sectors, is currently implementing a unique proprietary third-party glove analysis to ensure a range of their gloves are regularly checked for harmful contaminants, toxins and pathogens. This Fingerprint Glove Analysis mitigates the risk of intentional or accidental physical, chemical or microbiological glove contamination by inspecting five factors: the use of safe ingredients, cross-contamination potential, cleanliness, structural integrity and dermal compatibility.
Harmful toxins and contaminants in gloves have been identified in many peer reviewed scientific studies. This is now a real issue for companies producing consumer products, especially in industries such as organics and cannabis whose products must be handled by gloves and test clean.
Three key areas that can be tested for in a glove analysis to ensure safe product handling include:
Dermal compatibility tests for toxins and chemicals will flag any toxic chemical, such as o-Phenylphenol
GCMS testing for consistent quality and safety of glove raw materials
Cleanliness tests for pathogens inside and outside the surfaces of gloves – particularly pathogens also required in cannabis testing, such as E. coli and Salmonella, mold and fungus and pesticides.
For cannabis producers responsible glove sourcing is vital, especially as the COVID-related demand for single-use gloves exceeds supply, with poor quality, counterfeit and even reused gloves flooding the market. For producers with a product that rests very much on its quality, it’s important to focus on quality and not just cost when procuring gloves.
The culture of the cannabis industry is filled with passion that many envy, and for valid reasons. The roots of the cannabis plant go back thousands of years. As of this writing, there are no documented human deaths that were caused by a phytocannabinoid overdose. However, it is not all rainbows and unicorns.
Before breaking ground, fundraising, proper facility design, competitive application and permitting requirements are just the start. Once operating, businesses struggle to stay current with regulations that continue to evolve. Cannabis cultivators struggle to scale while mitigating pest infestations, which is a part of life in the conventional agricultural industry. A lack of consistent products frustrates consumers, while regulators and policy makers continue to struggle on the best way to regulate a commodity that has seemingly endless demand. The reality is dizzying!
However, amidst all of the challenges and opportunities, a continually overlooked tool stands out: a Quality Management System (QMS). Merriam-Webster defines a system as “an organized set of doctrines, ideas, or principles usually intended to explain the arrangement or working of a systematic whole.”
A QMS documents processes, procedures and responsibilities that ultimately direct an organization’s activities to meet customer and regulatory requirements as well as continually improve its effectiveness and efficiency. In other words – it steers innovation through the collection of data while ensuring products are safe for the consumer. For further reading, the American Society for Quality (ASQ), now over 70 years old, is an excellent resource and provider of resources and formal training programs that are recognized and revered around the world.
Step 1: Define your stakeholder requirements
This all starts with knowing your stakeholder (e.g., customer, regulatory body) requirements. For simplicity’s sake, let’s start with your customer; at a fundamental level, they expect safe, consistent and reliable products that impart a certain experience.
How does that translate into specifications? Let’s look at them one at a time.
What does “safe” mean? For an edible, safe means the product is free of physical, chemical and microbial hazards. Knowing what potential impurities could be in your product requires understanding your raw materials (inputs) and the manufacturing process. To take a deeper dive, some of the aspects of safety and quality, product specifications and testing considerations are discussed in this recent Cannabis Industry Journal article by Dr. Roggen and Mr. Skrinskas here.
An example of a compliant label in Oregon
What does “consistent” mean? This builds off and complements the safety profile. It could mean a consistent fill level, an acceptable range of cannabinoid concentration, and so on. For example, in the US Pharmacopeia’s peer-reviewed article about quality attributes of cannabis inflorescence (commonly known as flower or bud), they recommend 20% as the acceptable variance in cannabinoid content. For a product labeled as having 25% THC, the product will actually test to between 20% and 30%. This may be surprising, and discomforting for some, but the reality is that products on the market consistently fail to meet label claims.
What does “reliable” mean? That could mean that you always have inventory of certain products on the shelves at your dispensary. Defining “always” as a SMART goal – perhaps it means that you will have your top 3 products in stock at least 90% of the time. Customers need to feel like they can rely on your business to provide them with the products they want. Take the time to capture the data on what your customers want and work to satisfy their needs and you’ll watch your business really accelerate.
Step 2: Build your processes to meet these expectations
This is where your written standard operating procedures (SOPs), forms and records come into play. Your SOPs serve to memorialize your operations for consistency. Most SOPs in the cannabis industry are not written by the actual operators of a process. Rather, they are written by the legal and compliance team without review by the operators to confirm that what they are stating reflects operational reality. The audience needs to be the operators. Without effective SOPs that are utilized by your employees, your business will struggle to meet the established specifications. Cannabis businesses in Colorado, the oldest regulated adult-use cannabis market in the United States, continue to see 1 in 8 of their products fail final product testing! Cannabis businesses that understand their processes, document them in SOPs and have records to prove they follow their SOPs (see Step 3) are able to reduce errors that ultimately lead to costly rework and product failures.
Consistency in quality standards requires meticulous SOPs
Step 3: Monitor and improve
You have your requirements, you have your process, but how do you know that they are being adhered to? By the time you have results from a third-party lab, it’s too late. Look internally. Records and logs that show preventive maintenance was performed, room and canopy temperature and humidity checks, inventory reports, production records, extraction equipment report and employee training records shouldn’t be filled out only to be filed away. These records are data, which is your most valuable tool. Unfortunately, records are one of the most overlooked assets in today’s cannabis business. A team independent from operations (typically a Quality Unit) should be regularly reviewing these for inconsistencies and trends that can alert you to catastrophic failures before they occur.
Initially, the additional expenditure and learning curve may make this seem like an added burden, but keep in mind that succeeding in today’s cannabis industry requires long-term customer retention. By biting off one piece at a time, you can slowly implement a QMS that will improve your business, increase customer satisfaction, and ensure your brand is a staple for years to come. Remember, quality and compliance is a journey, not a “set it and forget it” situation.
The definition of a Quality Management System includes ‘continuous improvement’. Look forward to a future article which will discuss the importance of tools like a CAPA Program – Corrective Action Preventive Action (which all cannabis license holders in Colorado are required to have in place as of January 1, 2021) and how they complete your QMS, keeping you compliant and mitigating your business risks!
Any brewmaster from the more than 7,000 U.S. craft breweries will tell you one of two things: That their art is a science, or that their science is an art. The answer might depend upon the brewer’s individual approach, but a combination of experience, process, precise measurement and intuition is exactly what’s required to create great beer. In a very similar way, the cannabis industry has its own version of the brewmaster: Extraction technicians.
A cannabis extraction technician deploys knowledge from multiple science disciplines to apply industrial solvents, heat and pressure to plant matter through a variety of methods with the aim to chemically extract pure compounds. Extraction techs use their passion for the cannabis and hemp plants, combined with chemistry, physics, phytobiology and chemical engineering to help create a result that’s not quite art, but not quite completely science. By manipulating plant materials, pressure, heat and other variables, the extraction technician crafts the building block for what will become an edible, tincture or extract.
Similarly, brewmasters use their knowledge of multiple science disciplines like chemistry and microbiology, as well as different brewing processes and a variety of ingredients to develop creative recipes that result in consistent, interesting beers. The brewmaster’s work is both science and art, as well. And they also manipulate plant materials, pressure, heat and other variables to achieve their desired results.
Author Jeremy Diehl collects cannabis extract from equipment for testing
“I would certainly consider brewing to be an art and a science, but it takes a very disciplined approach to create consistent, yet ever evolving beers for today’s craft market,” says Marshall Ligare, PhD. Research Scientist at John I. Haas, a leading supplier of hops, hop products and brewing innovations. “We work to ensure brewers can create something different with every new beer, as well as something that helps create an experience as well as a feeling.”
In both brewing and extraction, the art comes in the subjective experience of the craftsman and his or her ability to curate the infinite possibilities inherent in each process. However, both are a science in their requirement of establishing production methodologies that guarantee a consistent, reliable product experience every time to win customer loyalty (and regulatory compliance). In the same way hops determine recipes for beer flavors, the cannabis plant determines extraction recipes, especially considering the role that terpenoids play in the quality, flavor and effects of the end product.
The development of new and appealing cannabis products is beginning to mimic the vast variety of craft beers now found all over the world. In the same way beer connoisseurs seek out the perfect stout, lager or IPA, discriminating cannabis consumers now search for that gem of a single-origin, specialty-strain vaporizer oil or irresistible dab extract.
“I see an exciting new day for quality-focused, craft extraction that tells a story, not only of where the cannabis plant might have been grown and how, but also the care that was taken in the processing of that strain into smokable or edible oil,” says John Lynch, Founder of TradeCraft. “Imagine the impact in the marketplace when product-makers figure out how to do seasonal one-offs where engaged connoisseurs are willing to pay a premium for the art behind limited releases.”
In the same way hops determine recipes for beer flavors, the cannabis plant determines extraction recipes
In either process, you’re essentially creating art with science. Each process works with different strains. Each is concerned with chemical and flavor profiles. Each has its own challenges. In both worlds, quality depends upon consistency. You’re creating art, but you need to replicate that art over and over – which can only occur with strict control of the process. Brewmasters seek control of things like yeast quantity and health, oxygen input, wort nutritional status and temperature, among other things. In their pursuit, extraction technicians seek to control temperature, pressure and flow rate–as well as all the ways these variables interact with each other. What enables this control in both efforts is the equipment used to achieve results.
“A modern brewhouse is very much like a scientific laboratory,” Ligare says. “Brewers treat their setup with the same care and attention a scientist gives to their lab equipment, and are equally concerned with precision, cleanliness and the purity of the result. With each new beer, they want to develop a process that can be controlled and replicated.”
The key to creating a precise process is to use instrument-grade extraction machinery that performs to specifications – and allows you to repeat the process again and again. The value of using high-quality instrumentation to manage and monitor either the brewing or extraction process cannot be overstated. Although it seems counterintuitive, this is where the “craft” comes into play for both brewing and cannabis extraction. Precise instrumentation is what allows the brewer or extraction “artist” to manipulate and monitor the conditions required to meet recipe standards. Along with the quality of the ingredients (hops, cannabis, hemp, etc.), the quality of the equipment utilized to create the product is one critical element impacting the end result. “Imagine the impact in the marketplace when product-makers figure out how to do seasonal one-offs where engaged connoisseurs are willing to pay a premium for the art behind limited releases.”
In cannabis extraction, a second crucial decision is determining which solvent is the best solution for the recipe you’re using and the end result you’re hoping to achieve. This decision is a part of the “craft” of extraction, and determined according to a combination of criteria. There’s no question that each solvent has a business case it serves best, and there is ongoingdebate about which approach is best. But overwhelmingly, the solvent that best serves the most business needs is CO2 due to its inherent versatility and ability to have its density tuned to target specific compounds.
“Control is what makes or breaks any craft product,” says Karen Devereux, Vice President of Northeast Kingdom Hemp. “We’re based in Vermont and love how Vermont is known for its quality craft beer, cheese and maple syrup. We wanted to bring that craft approach to hemp extraction, and everyone knows that any craft endeavor is focused on the details and getting them right again and again. You can’t do that without controlling every aspect of the process.”
Greater control of the process can also open up worlds of discovery. The inherent “tunability” of CO₂ enables the extraction technician to target specific compounds, enhancing the potential for experimentation and even whimsy. This can lead to entirely new products much in the way a brewer can control his process to create new, interesting beers.
American portrait photographer Richard Avedon famously declared that art is “about control,” describing the artistic process as “the encounter between control and the uncontrollable.” The same can be said for beer making and cannabis extraction. The more precisely you can control variables, the more options you’ll have for yourself and your customers. The more choices you’ll have with regard to different recipes and products. And the more loyalty you’ll ultimately generate among fans of your products.
To say 2020 was a historic year is an understatement.
Arizona landed in a solid eighth place among the top ten most successful cannabis states thanks to its expansive medical cannabis program. To close out the year, voters approved Proposition 207, also known as the Smart and Safe Arizona Act (SSAA), making Arizona one of 15 states, plus Washington D.C., to legalize the adult use of cannabis, which is expected to rocket the state’s overall cannabis sales to new heights.
It’s essential to this conversation that we clarify the two sides of this rapidly growing industry. Medical cannabis is a form of treatment, the adult use and consumption of cannabis is a choice. During the pandemic, in many medical cannabis states, the medical cannabis industry was deemed an essential service and allowed to continue providing valuable medicine to patients and caregivers. As medical cannabis programs continue to provide safer therapeutic options which are complementary to or serve as an alternative to many traditional treatments and narcotics, especially opioids, patients can be confident the need for medical programs will continue. Arizona’s adult use cannabis program imposes greater limitations on quantity and potency, while also requiring higher standards for packaging. We saw a trend during the pandemic as again, many states prioritized and allowed their medical programs to continue, while limiting adult use facilities, in the same manner as other non-essential businesses.
It’s also worth noting that we have seen many inevitable changes in patient behaviors during the pandemic, including an increased need for medical cannabis. There was a patient demand for convenience, safety and no-contact services, increased online ordering, scheduling and curbside pick-up or delivery. Many of these services were already on the rise in popularity throughout the various legal states. While Arizona’s recreational program prohibits delivery until at least 2023, retail adult use consumers will expect some of these services to extend to the new market. As life after the COVID-19 pandemic continues on and the need for some of these safer more convenient options also continues, we hope to see them more permanently implemented from a legal and regulatory perspective. For now, here are the highlights we’ll see come into play in the first few months of 2021 as Arizona adopts its new adult use cannabis program.
Smart and Safe Arizona Act (Prop 207):
Legalizes the sale, possession (one ounce) and consumption of adult use cannabis for adults at least 21 years old.
Adds a 16 percent excise tax on adult use cannabis sales, in addition to the state’s 5.6 percent, totaling a 21.6 percent tax.
Allocates an estimated $300 million in Arizona revenue to be divided between community college districts, municipal police, sheriff and fire departments, fire districts, highway funds, public health programs, infrastructure, and a new Justice Reinvestment Fund.
Allocates more than $30 million annually for addiction prevention, substance treatment, teen suicide prevention, mental health programs, and justice reinvestment projects.
Provides opportunities for expungement of certain lesser cannabis-related crimes such as possession, consumption, cultivation or transportation.
But of course, state law is just one part of the equation. Adult use cannabis facilities must be licensed separately from state to local levels, including counties to cities to local municipalities, all of which may also adopt rules and requirements through zoning and land use ordinances. Swift and certain timelines established by the Smart & Safe Act dictate the speedy launch of this new program, first utilizing the existing medical cannabis infrastructure.
Many Arizona consumers are under the impression that they’ll be able to walk into a dispensary on January 1, 2021 and buy cannabis. But that is not the case. They’ll have to wait until the Arizona Department of Health Services (AZDHS) completes the early applicant licensing process, which begins in January 2021. Currently, local and multistate operators are waiting for AZDHS to complete the rules and regulations for the adult use cannabis program. Here are two of the most significant steps to be navigated in the upcoming weeks:
Smart and Safe Arizona Act (Prop 207) – Step 1: The Rulemaking Process
AZDHS has been tasked with developing the rulemaking process for the Smart & Safe Act. The first draft of the adult use cannabis program rules has already been released, primarily consisting of the application requirements for the early applicant process. AZDHS collected its first round of public comments for consideration on Thursday, December 17, 2020. The exact details and parameters of the adult use cannabis program will not be finalized or known for certain until AZDHS completes the rulemaking process. We anticipate the next draft of adult use cannabis rules to be released sometime in early January.
Smart and Safe Arizona Act (Prop 207) – Step 2: The Application Process
AZDHS will begin accepting early applicants under the Smart & Safe Act on January 19, 2021, closing the process on March 9, 2021. Current medical cannabis license holders who apply for and acquire an adult use license in the early applicant process will be authorized to a dual-licensed dispensary (both medical and adult use license), as well as one offsite manufacturing facility (which may later be amended to include both medical and adult use manufacturing license), and offsite cultivation.
Early adult use license applicants are reserved for those that currently hold in good standing at least one Medical Marijuana Registration Certificate (“Medical Marijuana License”) and applicants applying to counties with no current operating dispensaries. Any county with a single operating dispensary (a medical cannabis dispensary) will be allocated an adult use license (dual license) as long as the medical license holder is in good standing for the application. All adult use licenses allocated to those counties without a current operating dispensary must keep that dispensary within that county.
AZDHS will have 60 days to process each application. Adult use licenses for counties without a current operating dispensary will be allocated through a random selection process, if more than two applications are received for that county. Additionally, upon the conclusion of the early applicant process, any adult use license that has not yet been awarded through that process, will be available to the general public and allocated through a random selection process.
This brings us to later phases of implementation of the Smart & Safe Act: within approximately six months of the adoption of the initial recreational program rules, AZDHS must develop and adopt the rules and regulations for the Social Equity Ownership Program (SEOP). The primary goal of the SEOP is to allocate 26 adult use licenses to “communities disproportionately impacted by the enforcement of previous cannabis laws.” In other words, communities disproportionately and negatively impacted by cannabis criminalization. Smart & Safe is light on the exact manner and process at this point, so Arizona voters and cannabis companies will look to AZDHS for the development and implementation of this important part of the adult use program. Stay tuned.
The cannabis industry is growing and evolving at an unprecedented pace and regulators, consumers and businesses continually struggle to keep up.
Cannabis businesses: How do you maintain an edge on the market, avoid costly mistakes?
Case Study: Costly Facility Build Out Oversights
David Vaillencourt will be joining a panel discussion, Integrated Lifecycle of Designing a Cultivation Operation, on December 22 during the Cannabis Quality Virtual Conference. Click here to register. A vertically integrated multi-state operator wants to produce edibles. The state requires adherence to food safety practices (side note – even if the state did not, adherence to food safety practices should be considered as a major facility and operational requirement). They are already successfully producing flower, tinctures and other oil derivatives. Their architect and MEP firm works with them to design a commercial kitchen for the production of safe edibles. The layout is confirmed, the equipment is specified – everything from storage racks, an oven and exhaust hoods, to food-grade tables. The concrete is poured and walls are constructed. The local health authority comes in to inspect the construction progress, who happens to have a background in industrial food-grade facilities (think General Mills). They remind the company that they must have three-compartment sinks with hot running water for effective cleaning and sanitation, known as clean-out-of-place (COP). The result? Partial demolition of the floor to run pipeline, and a retrofit to make room for the larger sinks, including redoing electrical work and a contentious team debate about the size of the existing equipment that was designed to fit ‘just right.’
Unfortunately, this is just one more common story our team recently witnessed. In this article, I outline a few recommendations and a process (Quality by Design) that could have reduced this and many other issues. For some, following the process may just be the difference between being profitable or going out of business in 2021.
The benefits of Quality by Design are tangible and measurable:
Reduce mistakes that lead to costly re-work
Mitigate inefficient operational flow
Reduce the risk of cross-contamination and product mix-ups. It happens all the time without carefully laid out processes.
Eliminate bottlenecks in your production process
Mitigate the risk of a major recall.
The solution is in the process
Regardless of whether you fall in the category of a food producer, manufacturer of infused products (MIP), food producers, re-packager or even a cultivator, consider the following and ask these questions as a team.
People
By standardizing and documenting safety procedures, manufacturers mitigate the risk of cannabis-specific concerns
For every process, who is performing it? This may be a single individual or the role of specific people as defined in a job description.
Does the individual(s) performing the process have sufficient education and training? Do you have a diverse team that can provide different perspectives? World class operations are not developed in a vacuum, but rather with a team. Encourage healthy discourse and dialogue.
Process
Is the process defined? Perhaps in a standard operating procedure (SOP) or work instruction (WI). This is not the general guidance an equipment vendor provided you with, this is your process.
How well do you know your process? Does your SOP or WI specify (with numbers) how long to run the piece of equipment, the specification of the raw materials used (or not used) during the process, and what defines a successful output?
Do you have a system in place for when things deviate from the process? Processes are not foolproof. Do not get hung up on deviations from the process, but don’t turn a blind eye to them. Record and monitor them. In time, they will show you clear opportunities for improvement, preventing major catastrophes.
Materials
What are the raw materials being used? Where are they coming from (who is your supplier and how did you qualify them)?
Start with the raw materials that create your product or touch your product at all stages of the process. We have seen many cases where cannabis oils fail for heavy metals, specifically lead. Extractors are quick to blame the cultivator and their nutrients, as cannabis is a very effective phytoremediator (it uptakes heavy metals and toxins from soil substrate). The more likely culprit – your glassware! Storing cannabis oil, both work in process or final product in glass jars, while preferred over plastic, requires due diligence on the provider of your glassware. If they change the factory in which it is produced, will you be notified? Stipulate this in your contract. Don’t find yourself in the next cannabis lead recall that gets the attention of the FDA.
Savings is gained through simple control of your raw materials. Variability in your raw material going into the extractor is inevitable, but the more you can do to standardize the quality of your inputs, the less work re-formulating needs to be done downstream. Eliminate the constant need to troubleshoot why yields are lower than expected, or worst case, having to rerun or throw an entire batch out because it was “hot” (either too much THC in the hemp/CBD space or pesticides/heavy metals). These all add up to significant downstream bottlenecks – underutilized equipment, inefficient staff (increase in labor cost) all because of a lack of upstream controls. Use your current process as a starting point, but implement a quality system to drive improvement in operational efficiency and watch your top line grow while your bottom-line decreases.
Consistency in quality standards requires meticulous SOPs
Have you tested and confirmed the quality of your raw material? This isn’t just does it have THC and is it cannabis, but is it a certain particle size, moisture level, etc.? Again, define the quality of your raw materials (specifications) and test for it.
Remember – ranges are your friend. It is much better to say 9-13% moisture than “about 10%”. For your most diligent extractor, 11% will be unacceptable, but for a guy that just wants to get the job done, 13% just may do!
Test your final product AFTER the process. Again, how does it stack up against your specifications? You may need to have multiple specifications based on different types of raw material. Perhaps one strain with a certain range of cannabinoids and terpenes can be expected for production.
Review the data and trend it. Are you getting lower yields than normal? This may be due to an issue with the equipment, maybe a blockage has formed somewhere, a valve is loose, and simple preventive maintenance will get you back up and running. Or, it could be that the raw biomass quality has changed. Either way, having that data available for review and analysis will allow you to identify the root cause and prevent a surprise failure of your equipment. Murphy’s law applies to the cannabis industry too.
You are able to predict and prevent most failures before they occur
You increase the longevity of your equipment
You are able to predict with a level of confidence – imagine estimating how much product you will product next month and hitting that target – every time!
Business risks are significantly mitigated – a process that spews out metal, concentrates heavy metals or does not kill microbes that were in the raw material is an expensive mistake.
Your employees don’t feel like they are running around with their hair on fire all the time. It’s expensive to train new employees. Reduce your turnover with a less stressed-out team.
Takeaways
Maintaining a competitive edge in the cannabis industry is not easy, but it can be made easier with the right team, tools and data. Our recommendations boil down to a few simple steps:
Make sure you have a chemical or mechanical engineer to understand, optimize and standardize your process (you should have one of these on staff permanently!)
Implement a testing program for all raw materials
Test your raw materials – cannabis flower, solvents, additives, etc. before using. Work with your team to understand what you should and should not test for, and the frequency for doing so. Some materials/vendors are likely more consistent or reliable than others. Test the less reliable ones more frequently (or even every time!)
Test your final product after you extract it – Just because your local regulatory body does not require a certain test, it does not mean you should not look for it. Anything that you specified wanting the product to achieve needs to be tested at an established frequency (and this does not necessarily need to be every batch).
Repeat, and record all of your extraction parameters.
Review, approve and set a system in place for monitoring any changes.
Congratulations, you have just gone through the process of validating your operation. You may now begin to realize the benefits of validating your operation, from your personnel to your equipment and processes.
One of the biggest challenges that cultivators, processors and distributors face in doing business is the requirement to track the product at every step in the production process, from seed to sale. When you add the wide range of label sizes and requirements across the supply chain, labeling can feel overwhelming. While business systems such as METRC, BioTrack, MJFreeway and others are key, integrating accurate and secure barcode labeling with those systems will streamline the end-to-end process while meeting traceability requirements. Here are some things to consider, no matter what role in the cannabis supply chain you play.
Cultivation: Where Tracking and Labeling Starts
Cultivation is where the tracking process begins – integrating barcode labeling METRC, BioTrack, MJ Freeway from the start will streamline the end-to-end process
It’s crucial to implement accurate labeling processes from the beginning, whether growing for a customer or your own vertically integrated operation. The cannabis industry is faced with strict labeling regulations for a variety of cannabis products. Start with a labeling system that can integrate with METRC, BioTrack, MJ Freeway or other seed to sale software solutions. Your barcode labeling solution should also include label approval requirements, so you have role-based access and transparency with label changes and print history in case of issues or recalls. Whatever cannabis labeling regulations your business faces, label design software helps you create compliant cannabis labels throughout the supply chain, from grower to consumer.
Radio Frequency Identification (RFID) Labeling
Select regulations require growers to leverage RFID technology to track the location of the plants in their grow houses. RFID technology also enables accurate real-time inventory analysis and helps reduce manual labor costs, as well as errors that can occur with manual counting. To accurately encode RFID tags with variable plant data, be sure you are using a barcode labeling system that can enable easy RFID tag encoding that integrates data from all your business systems. Fastening RFID tags to plants across your grow house floor enables quick and easy location tracking, and RFID reading removes the need for a manual line of sight and allows hundreds of tags to be read at the same time, speeding up shipping and receiving.
Lab Testing
After a plant is cultivated, a certain percentage is sent to a lab to be tested to ensure its proper strain, weight and compound makeup. After your product has been lab tested, leverage the data from your certificate of analysis to accurately display on your cannabis product labels, including:
Pass/fail chemical testing
Final date of testing & packaging
Identification of testing lab
Cannabinoid profile & potency levels
Efficiently display lab testing results on product labels with the use of a QR code for the consumer to review the independent lab’s certificate of analysis
Processing and Production: Tracking and Labeling After the Plant Has Been Harvested
A lot of information needs to go on a cannabis label. Whether you’re producing pre-rolls, packaged flower, edibles, beverages, topicals or cartridges, your labeling software must have the capability to create a wide variety of label sizes with barcodes that encode a large volume of data, while also being fully compliant and showing consumer appeal.
Your cannabis labeling software should do the following for you:
Support database integration to populate variable data from METRC, BioTrack, and other systems
Import high-resolution artwork and leverage with dynamic barcodes and variable data
Contain barcode creation wizards for 1D & 2D barcodes
Automate weigh & print
RGB/CMYK color matching
Feature secure label approval processes, label change tracking and print history
Offer WYSIWYG (What You See is What You Get) printing
Automatically trigger printing directly from scales and scanners when cannabis is weighed
Automatically integrating data with your barcode labeling software improves regulatory compliance, security and reduces manual processes that can lead to labeling errors
Integrate labeling with your seed to sale software solution to automatically trigger label printing by an action in your seed to sale system or by monitoring a database. By integrating your label printing system with your seed to sale traceability system, you can expect to minimize errors, increase print speeds and maximize your ROI. Your business system already holds the variable data such as product names, license number, batch or lot codes, allergens, net quantity, cannabis facts, warning statements and more. By systematically sending this data to the right label template at the right time, labeling becomes an efficient and cost-effective process.
Distribution: labeling for consumer and industry demands
The ability to manage and distribute inventory efficiently is critical in the cannabis market. Warehouses and distributors need to ensure proper storage, handling and traceability of product, from the warehouse to the truck.
Leverage your labeling software to easily create:
Packaging labels
Shipping labels
Case & pallet labels
Inventory labels
If you use the same data for your documents and labels, consider moving document printing into your label design software for greater efficiency. An advanced label creation and integration software enables label and document printing standardization by allowing multiple database records to be on one file. That means when new documents or labels come into your database, your software can seamlessly integrate.
Dispensaries can benefit from integrated seed to sale labeling for traceability, speed to market
Whether you’re a small outlet or a large dispensary, you benefit from integrated barcode labeling that starts from the beginning of the process. How? When barcode labeling software is integrated with seed to sale software, product is fully traced throughout the entire process, from tagging each plant at cultivation to identifying the consumer at point of sale, and accurately communicating that data back to METRC, BioTrack and other critical systems. Some dispensaries do package raw flower onsite, which many times means manually weighing, recording and entering the weight on the label, which is a time consuming and error-prone process. Integrating weigh and print functionality with barcode software enables dispensaries to use the action of weighing raw flower to automatically trigger the label print job. The variable weight is then accurately and automatically populated on cannabis flower package labels, creating an accurate and efficient on-demand labeling process for dispensaries. With efficient labeling processes, time spent creating, correcting, approving and printing labels will be reduced, getting product on the shelves faster.
