Clean, ecologically sound production methods are the ideal for any cultivation or farming activity. Taking from the earth only what is needed to grow the crop and leaving behind little in the way of chemicals and land/water loss is the goal; with cannabis grow facilities, it can also be a reality.
This type of production does require some capital investment into state-of-the-art equipment and facilities, with standards that are equal to or even surpass current EPA and USDA regulations. While cannabis growing does not yet have access to the organic certification, that doesn’t mean growers can’t abide by and even go beyond the rules, to grow clean, healthy and environmentally sound cannabis.
There are a few essential elements required to make this kind of operation a reality.
Ecologically advanced use of power
For any indoor facility, one of the key elements is lighting. Using as energy efficient a system as possible is key. The best option at the moment is LEC lighting, which provides a spectrum of light that is very close to natural. This makes checking on plant progress more realistic and, with the inclusion of UV-B in the spectrum, can improve yields as well. In addition, the LEC bulbs have a long life—up to 2 years—which means lower maintenance costs as well.
Another aspect of growing that tends to use a lot of power is the cooling system. A standard HVAC system will be power intensive, so alternative ones like water chilled climate control systems are just as effective and 30% more power efficient. These systems are also able to reuse wasted power by feeding it back into the system, creating an additional 10% energy reduction. In addition, when the outdoor air temperature dips below 45 degrees, a water chilled system can switch to using the outside air, creating 60—70% in energy savings.
Efficient management of water resources
Cultivators depend heavily on water to ensure that the plants are hydrated and able to absorb the nutrients they need to grow and thrive. The result for many however is an excessive waste of water. This is a problem when a grow facility is leveraging municipal water resources. A water meter helps to manage and track usage but to ensure that it is used as efficiently as possible, a “top feeding” method of usage ensures minimal water waste (5% or less).
Effective waste management
Wastewater is a byproduct of any water intensive cultivation method but there again, managing the systems to ensure that what water isn’t reused and becomes “gray water” is still as clean as possible is the ideal. A high-quality filtration system keeps sediment, chlorine and other harmful elements out of the water supply — and out of the municipal sewage system. Further, by using organic matter throughout the growing process, the wastewater that is produced will meet every federal standard for organic food production.
All plant waste in a grow facility—for example: stems and fan leaves—is disposed of according to state and local laws. With cannabis plants, that requires a certain level of security, including locked dumpsters that are only unlocked and placed outside when the removal trucks arrive on site.
Organic farming practices
Using OMRI (Organic Materials Review Institute) listed soil is an essential part of clean, environmentally friendly growing. To ensure the proper nutrients are available for each harvest, once a crop is gathered, the soil is transferred to a local landscape company to compost and reuse.
Pesticides need to obviously be avoided and all fertilizers need to be USDA approved as organic and all nutrients need to be certified by OMRI to ensure they don’t contain any synthetic materials.
Considering all of these aspects is essential to creating an ecologically friendly grow facility with tremendous yields that are clean and safe for the end consumer, as well as minimizing the impact to the earth.
The edible cannabis market in Canada is still green. Delayed by a year from the legalization of dried flower, the edibles and extracts market poses significant opportunities for manufacturers. Edibles and extracts typically have higher profit margins than dried flower (“value-added” products) and consumer demand appears to be high and rising. So, what is causing trouble for cannabis companies trying to break into edibles and extracts? Below are four observations on the market potential of edibles in Canada.
Canada’s Edibles Market: The Numbers
In 2020, Canada – the largest national market in the world for cannabis products – grew more than 60%, largely as a result of the introduction of new products introduced in late 2019, often called “Cannabis 2.0,” which allowed the sale of derivative products like edibles. Deloitte estimates that the Canadian market for edibles and alternative cannabis products is worth $2.7 billion, with about half of that amount taken up by edibles and the rest distributed amongst cannabis-infused beverages, topicals, concentrates, tinctures and capsules. More recently, BDSA forecasts the size of the Canadian edibles market to triple in size by 2025 to about 8% of the total cannabis dollar sales.
In December 2020, the Government of Canada reported that edibles made up 20% of total cannabis sales; Statistics Canada data shows that 41.4% of Canadians who reported using cannabis in 2020 consumed edibles. While sales have gone up and down over the course of the COVID-19 pandemic, there are clear indications that there is a substantial demand for edibles and extract products, which can be consumed more discreetly, with greater dosage precision and with fewer adverse effects (as opposed to smoking).
1) Complex Regulatory Standards are a Major Barrier
Cannabis edibles compound the already existing problems around the conceptualization of cannabis products regulation. How should it work? Edibles can be considered in any of the following categories:
Cannabis as a pharmaceutical with medical application. Requires strict dosage and packaging requirements;
CBD as a nutraceutical with health benefits claimed. Requires specific nutraceutical regulations be followed;
Food product to be consumed. Must comply with food safety regulations around biological, chemical, physical hazards through a risk-based preventive control program. A full supply chain and ready-to-recall based system of regulatory standards need to be followed.
Incorporating elements from each of these three regulatory regimes into a single regulatory standards body is a confusing logistical and compliance challenge for both the regulators, and the producers and retailers of the product.
In mid-2019, the Government of Canada released the Good Production Practices Guide for Cannabis. This merged cannabis-specific regulations with food safety-specific regulations. Rigorous food safety requirements were combined with equally rigorous cannabis production and processing requirements, resulting in extremely laborious, detailed and specific regulations. These span everything from building design and maintenance, to pest control, to employee sanitation, to traceability – at all levels of the process. Navigating these regulations is a challenge, especially for many smaller producers who lack the necessary resources, like automation technology, to devote to understanding and tracking compliance.
2) Low Dosage Regulations Give an Edge to the Illicit Market
When edibles were legalized, THC dosage was capped at 10mg per package. For more experienced consumers, especially those who are dealing with chronic pain and other medical needs, this limit is far too low – and the unregulated market is more than able to fill this gap. One analyst from Brightfield pointed out that the dosage restriction, in combination with other regulations, will make it harder for the edibles market to grow in Canada.
It also makes the unregulated market almost impossible to beat. Barely more than half of cannabis consumers in Canada buy exclusively from government-licensed retailers, while 20% say that they will only buy unregulated products. According to a Deloitte report, 32% of legacy cannabis consumers said that unregulated products were better quality, and 21% reported that they preferred unlicensed products because there were more options available. Almost half of respondents also reported that quality was the biggest factor that would cause them to switch to regulated sources, and 28% said that higher THC content would prompt them to switch.
3) There is a Big Price Disparity between Legal and Illicit Edibles
As a result of dosage requirements and other factors, price per gram of regulated edible product is much higher than that of flower, unregulated edibles and edibles available through regulated medical distributors.
If you take the BC Cannabis Store’s price for Peach Mango Chews as an example: a 2pc package is $5.99. Since the dosage limits at 10mg per package, that’s the equivalent of $0.60/mg or $600/gram. A quick Google search reveals that an easily available edible from a medical cannabis distributor contains 300mg of THC and sells for $19.00, a price of $63.00/gram.
That means that not only is 10mg too low a dose for many users to achieve the result they were looking for, but the dosage restriction also makes the products less attractive from both a nutrition and cost standpoint. Deloitte reportsthat higher prices is the reason that 76% of long-time cannabis consumers continued to purchase from unregulated sources. The regulated industry as a whole is missing its legal market opportunity, where consumers prefer a lower price product with a greater range of dosage availability.
4) The Range of Products Available is Too Limited for Consumers
For most of 2020, chocolate edibles were the dominant product in this category in the Canadian market, garnering 65% of all edibles sales. But is this reflective of consumer wants? Despite a demand for other kinds of edibles like the ever-popular gummies, there are still only a few edible brands that offer the range of products consumers are asking for. According to research from Headset, there are 12 manufacturers in Canada making edibles but only two of them produce gummies. In comparison, 187 brands make gummies in the United States.
While some of this delay is likely due to the long licensing process in Canada and the newness of the market, there are other factors that make it challenging to bring a variety of products to market. The province of Quebec, Canada’s second-largest province, has banned the sale of edibles that resemble candies, confections, or desserts that could be attractive to children – giving yet another edge to unregulated sellers who can also capitalize on illegal marketing that copies from existing candy brands like Maynard’s.
When companies do want to introduce new products or advertise improvements to existing product lines, they are restricted by stringent requirements for packaging and marketing, making it harder to raise brand awareness for their products in both the legal and unregulated markets. Industry players are also complaining about government restrictions on consumers taste-testing products, which further compounds challenges of getting the right products to market.
In the meantime, illicit producers have also shown themselves to be savvy in their strategies to capture consumers. It is not uncommon to find illicit products packaged in extremely convincing counterfeit packaging complete with fake excise stamps. New consumers may assume the product they are purchasing is legal. Availability of delivery options for higher dosage, lower price illicit products is also widespread. All of this adds up to significant competition, even if it were easier to meet regulatory requirements.
Conclusion: Significant Room for Growth Remains Limited by Government Regulations
These four challenges are significant, but there are a number of opportunities that present themselves alongside them. A year and a half into the legalization of edibles, cannabis companies are getting a better picture of what Canadian consumers want and low dosages are proving to be desirable for Canadian consumers in some areas.
In particular, sales of cannabinoid-infused beverages far outpaced other edibles categories last year, likely tied to the availability of these products in stores over the summer of 2020. BDSA’s research has shown that, in contrast with American consumers, the lower THC dosage for cannabis beverages is an advantage for Canadian consumers. Major alcohol brands like Molson Coors and Constellation Brands are investing heavily in this growing product area – though there the dosage limits also apply to how many products a consumer can buy at a time.
At the same time, the large quantity of unsold cannabis flower sitting in storage also poses an opportunity. While its quality as a smokeable product may have degraded, this biomass can be repurposed into extracts and edibles. Health Canada has also shown some responsiveness to industry needs when it shifted its stance to allow for Modified Atmosphere Packaging (MAP), which will help improve shelf life of products.
While strict regulatory obstacles remain, challenges will continue to outweigh opportunities and the illicit market will remain a strong player in the edibles market. As regulations become clearer and producers become more accustomed to navigating the legal space, barriers to entry into the regulated cannabis market and specifically the extracts and edibles market, will decrease. Meanwhile, those getting into the edibles market will do well to be wary of the challenges ahead.
Update: Governor Ned Lamont has signed S.B. 1201 into law, officially legalizing cannabis in the state of Connecticut
On June 16, 2021, the Connecticut House of Representatives voted to pass their version of S.B. 1201, a bill that legalizes adult use cannabis. Following the House’s approval of the changes, the bill made its way back to the Senate on June 17, where they approved all changes. It now heads to the Governor’s desk, where Gov. Ned Lamont is expected to sign it into law.
With Gov. Lamont’s signature, Connecticut will become the 19th state in the country to legalize adult use cannabis. The bill is slated to go into effect on July 1, just a couple of weeks away.
Come July 1, adults in Connecticut can legally possess up to 1.5 ounces of cannabis in public and up to five ounces at their home. The bill allows for adults to grow at home, just not until 2023 unless you are an existing patient registered in the medical program.
According to the Marijuana Policy Project (MPP), the bill will expunge cannabis records for low-level crimes and puts “the bulk of excise tax revenues into a Social Equity and Innovation Fund, which will be used to promote a diverse cannabis industry and reinvest in hard-hit communities.” Half of the cannabis business licenses issued will go to social equity applicants that can receive funding, workforce training and other types of assistance from the program.
DeVaughn Ward, senior legislative counsel at MPP, says the bill includes provisions to repair harm done by the prohibition of cannabis. “The Connecticut Legislature’s commitment to legalizing cannabis through a justice-centered approach is commendable,” says Ward. “For decades, cannabis prohibition and criminalization has harmed some of the state’s most vulnerable communities. This bill not only ends this failed and unjust policy, but it also includes measures that will work to repair the harm that it has caused. This state will be a model for others to follow.”
The bill includes strong protections for employees, tenants and students by limiting discriminatory actions based on positive drug tests. It also dedicates 25% of tax revenue from cannabis to go toward mental health and substance use treatment.
SC Labs, a cannabis testing company with roots in Santa Cruz, California, announced this week that they have developed a comprehensive hemp testing panel that covers a number of contaminants on a national regulatory level. In the press release, the company says they aim to fill the void of national hemp testing requirements.
The hemp testing panel they have developed purportedly meets testing standards in states that require contaminant levels below a certain action limit. The SC Labs hemp testing panel could theoretically be used for regulatory compliance testing across the country, reaching action limits and analyte levels that meet the strictest state requirements.
The panel tests for pesticides, heavy metals, microbiology, mycotoxins, residual solvents and water activity.
The panel is one sign of progress on the long road to nationally harmonized testing standards. “As an industry, we’ve been advocating for national, standardized, and transparent testing regulations for years now,” says Jeff Gray, CEO of SC Labs. “The government has been slow to respond so we decided it was time to act. As an industry, we’ve been advocating for national, standardized, and transparent testing regulations for years now. The government has been slow to respond so we decided it was time to act.”
SC Labs is headquartered in Santa Cruz, but has licenses in California, Oregon, Texas and Colorado (pending). Their California and Oregon locations are both ISO 17025-accredited and conducting THC-containing cannabis testing, as well as hemp testing.
The word “audit” evokes various emotions depending on your role in an organization and the context of the audit. While most are familiar with and loathe the IRS’s potential for a tax audit, the audits we are going to discuss today are (or should be) welcomed – proactive internal quality audits. A softer term that is also acceptable is “self-assessment.” These are independent assessments conducted to determine how effective an organization’s risk management, processes and general governance is.
“How do you know where you’re going if you don’t know where you’ve been” – Maya Angelou
Internal quality audits are critical to ensuring the safety of products, workers, consumers and the environment. When planned and performed periodically, these audits provide credible, consistent and objective evidence to inform the organization of its risks, weaknesses and opportunities for improvement. Ask yourself the question: do your clients/vendors rely on you to produce reliable, consistent and safe products? Assuming the answer is yes, what confidence do you have, and where is the documented evidence to support it?
Compliance units within cannabis businesses are typically responsible for ensuring a business stays legally compliant with state and federal regulations. This level of minimum compliance is critical to prevent fines and ensure licenses are not revoked. However, compliance audits rarely include fundamental components that leave cannabis operators exposed to many unnecessary risks.
As a producer of medical and adult-use products that are ingested, inhaled or consumed in other forms by our friends, family and neighbors, how can you be sure that these products are produced safely and consistently? Are you confident that the legal requirements mandated by your state cannabis control board are sufficient? Judging by the number of recalls and frustrations voiced by the industry regarding the myriad of regulations, I would bet the answer is no.
What questions do internal audits address? Some examples include:
Are you operating as management intends?
How effective is your system in meeting specified objectives? These objectives could include quality metrics of your products, on-time delivery rates and other client/customer satisfaction metrics.
Are there opportunities to improve?
Are you doing what you say you do (in your SOPs), and do you have the recorded evidence (records) to prove it?
Are you meeting the requirements of all applicable government regulations?
There are potential drawbacks to internal audits. For one, as impartiality is essential in internal audits, it may be challenging to identify an impartial internal auditor in a small operation. If your team always feels like it is in firefighting mode, it may feel like a luxury to take the time to pull members out of their day-to-day duties and disrupt ongoing operations for an audit. Some fear that as internal assessments are meant to be more thorough than external assessments, a laundry list of to-do items may be uncovered due to the audit. But, these self-assessments often uncover issues that have resulted in operational efficiencies in the first place. This resulting “laundry list” then affords a proactive tool to implement corrective actions in an organized manner that can prevent the recurrence of major issues, as well as prevent new issues. The benefits of internal audits outweigh the drawbacks; not to mention, conducting internal audits is required by nearly every globally-recognized program, both voluntary (e.g. ISO 9001 or ASTM Internationals’s Cannabis Certification Program) and government required programs such as 21 CFR 211 for Pharmaceuticals.
Internal Auditing is a catalyst for improving an organization’s effectiveness and efficiency by providing insight and recommendations based on analyses and assessments of data and business processes. Additional benefits of internal audits include giving your organization the means to:
Ensure compliance to the requirements of internal, international and industry standards as well as regulations and customer requirements
Determine the effectiveness of the implemented system in meeting specified objectives (quality, environmental, financial)
Explore opportunities for improvement
Meet statutory and regulatory requirements
Provide feedback to Top Management
Lower the cost of poor quality
Findings from all audits must be addressed. This is typically done in accordance with a CAPA (Corrective Action Preventive Action) program. To many unfamiliar with Quality Management Systems, this may be a new term. As of Jan 1, 2021, this is now a requirement for all cannabis licensed operators in Colorado. Many other states require a CAPA program or similar. Continuing education units (CEUs) are available through ASTM International’s CAPA training program, which was developed specifically for the cannabis industry.
Examples of common audit findings that require CAPAs include:
Calibration – Production and test equipment must be calibrated to ensure they provide accurate and repeatable results.
Document and record control – Documents and records need to be readily accessible but protected from unintended use.
Supplier management – Most standards have various requirements for supplier management that may include auditing suppliers, monitoring supplier performance, only using suppliers certified to specific standards, etc.
Internal audits – Believe it or not, since internal audits are required by many programs, it’s not uncommon to have a finding related to internal audits! Findings from an internal audit can include not conducting audits on schedule, not addressing audit findings or not having a properly qualified internal auditor. Are you looking for more guidance? Last year, members of ASTM International’s D37 Committee on Cannabis approved a Standard Guide for Cannabis and Hemp Operation Compliance Audits, ASTM D8308-21.
If you are still on the fence about the value of an internal audit, given the option of an inspector uncovering a non-conformance or your own team discovering and then correcting it, which would you prefer? With fines easily exceeding $100,000 by many cannabis enforcement units, the answer should be clear. Internal audits are a valuable tool that should not be feared.

Process Scale Up in the Cannabis/Hemp Industry
Darwin Millard, Committee ViceChair on ASTM International’s D37.04 on Processing & Handling of Cannabis
Charlotte’s Web Holdings announced a new collaboration with the University of Colorado-Boulder and their Research and Education Addressing Cannabis and Health (REACH) Center. The University’s REACH Center will conduct a preclinical study on how hemp oil can influence sleep quality and anxiety.
The study will use Charlotte’s Web hemp products, including their full spectrum hemp formulations containing CBN, CBD and less than 0.3% THC. Monika Fleshner, PhD, Professor of Integrative Physiology and member of the Center for Neuroscience at the University of Colorado, will be the project lead and will conduct the study in her Stress Physiology Laboratory. “There is a great need for properly controlled experimental studies that are designed to test the potential neural and physiological impacts of hemp derived phytocannabinoids,” says Dr. Fleshner. “With support from CU REACH and Charlotte’s Web, our research will explore both the efficacy and mechanisms of how these substances can affect complex brain-mediated behavior, such as disturbed sleep.”
Tim Orr, senior vice president of Charlotte’s Web and president of its CW Labs division, is currently working on more than twelve scientific research studies with the company. “Charlotte’s Web is committed to advancing science on the benefits and safety of CBD and other hemp phytocannabinoids through rigorous scientific investigations such as this sleep and anxiety study,” says Orr. “We’re honored to team up with CU’s REACH Center to explore the potential impacts of full-spectrum hemp extract with CBD and CBN on anxiety and sleep quality.”
Long term, Charlotte’s Web expects this study will help build the foundation for future clinical studies to “better understand how specific ratios of cannabinoids and different delivery formats are effective at supporting improved sleep quality and instilling healthier sleep architecture in humans,” reads the press release.
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
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.
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.
Anyone in the cannabis industry is well aware that theft of crops can economically devastate a grower. Security is critical, and thankfully, growers and dispensaries have many tools available to protect their investment. There is simply no excuse for not having a solid security posture to keep your business in compliance, from public-private partnerships to advanced security tools – in fact, it’s required in most jurisdictions.
In 2020, nationwide cannabis sales increased 67%, and support for legal marijuana reached an all-time high of 68%. New Frontier Data found that U.S. legal cannabis market is projected to double to $41.5 billion by 2025.
The industry’s advancement impacts numerous areas such as job and tax revenue creation and providing a wide variety of valuable opportunities. For cannabis facilities to keep up with the market expansion and experience success, they must face two significant challenges: achieving adequate security and efficient business operations. Though both can be seen as separate concerns, growers and producers must merge processes and solutions to tackle the issue as a whole.
Along with rapid growth, dispensaries face traditional security risks, such as workplace violence and retail theft, while cybersecurity risks have also become more prevalent. These potential issues make it clear that the stakes are high, and as the potential impact on a business rises, the need for real-time, predictive response increases. Insider threats are another issue plaguing the industry when you look at the rate of theft, diversion and burglary that is attributable to employees.
The cannabis market is complex: it’s expanding rapidly, has to meet essential regulatory requirements and faces high-security risks. Therefore, security needs to be looked at holistically since it can be challenging to determine where a potential threat may originate.
With security top of mind, it is critical to move away from responsive behaviors and seek ways to manage security in a manner that gets ahead of threats, prevent them before they happen and respond to them in real-time. But does a grower or retailer have the time and expertise to manage all this while keeping an eye on how security affects the business?
Remote Security Operations
The ability to comply with government regulations and protect a valuable cannabis crop at all stages of its journey from seed to sale makes security systems a mission-critical asset for cannabis growers. Security operations centers create a safer and more productive environment and provide state-of-the-art tools to protect employees, retail locations and grow facilities. But some businesses in the cannabis market may not have the resources or space to have their centralized security operations, leading them to piece-meal security together or do the best with what they can afford at the time. Running these facilities can also be prohibitively expensive.
But new options take the process of security off the table. The business can focus on the growth of its core functions. Remote security operations services allow companies to take advantage of advanced security services typically only possible in larger enterprise environments. These services are offered on a subscription basis, delivered through the cloud, and are entirely customizable to detect risks unique to your business operations while saving each company significant expense.
Centralized security operations centers leverage intelligent tools, standard operating procedures and proven analytic methods to provide cannabis facilities with the information and guidance necessary to mitigate issues like retail or grow theft before they can have a significant impact.
The integrated, holistic response center staffed by experienced operators and security experts delivers a comprehensive security and regulatory compliance method. This approach is designed to provide complete data about what is happening across a cannabis business, from seed to sale, and how individual events can impact the company as a whole. As a result, stakeholders get the security intelligence they need, without the high overhead, personnel investments and complex daily management.
For those businesses in the cannabis market looking to supplement their security operations with other workforce but may not have the budget or infrastructure to do so, remote security operations services are something you should consider. With the experts handling all the heavy lifting, leaders can focus on growth. And, right now, in the cannabis industry, the sky is the limit in terms of opportunity.
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.
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:
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:
