Sustainability in Cannabis Packaging: Balancing Preservation and Environmental Impact

By Jack Grover

Even a cursory review of cannabis reveals that the market has been notoriously wasteful, polluting the environment with chemical fertilizers, misused pesticides, contaminated plants, and—perhaps most problematically—thoughtlessly excessive packaging.

The industry is in dire need of sustainable practices, and the easiest way to start an impactful new trend is from the outside in: a.k.a., adjusting how you’re parceling your products.

Honing in on sustainable packaging isn’t just a good move for the environment. It’s also more cost-effective, less labor-intensive and allows you to provide consumers with the best possible version of your flower—no matter how far through the supply chain it’s had to travel before hitting retail shelves.

Cannabis has progressed: It’s time for its packaging to do the same

By the time legalization began sweeping the nation, the industry already had several decades of experience operating underground. With that discretion came a lot of built-in habits around not attracting attention, and for packaging, the focus was solely on not looking like a cannabis product.

An overabundance of plastic isn’t cutting it anymore—not only when it comes to environmental friendliness, but for the integrity of the product itself.

Today, increased legalization grants operators the freedom to expand without the fear of being seen, and as a result, there’s no longer any excuse for wasteful packaging to be the industry’s norm. Glass jars, Ziplocks and an overabundance of plastic isn’t cutting it anymore—not only when it comes to environmental friendliness, but for the integrity of the product itself.

“I’ve been designing packaging in the cannabis industry since 2013, and a lot of trends have come and gone. We used to put flower in plastic Rx jars and paper envelopes. In general, there was a lot of waste: excess boxes and jars that all get thrown away,” says Legacy’s Chief Cannabis Officer Ryan Hedrick. “And when consumers pull the products out of those containers, your marketing doesn’t remain intact. The box gets thrown away, and now they’re just carrying around a labelless jar. Not only is it bad for the environment, but it isn’t helping you promote your brand at all.”

How sustainable storage optimizes curing and shelf life of flower

As for the curing process, Hedrick used to use airtight buckets, which both took up a lot of room and wasn’t at all effective for maintaining cannabis’s ideal humidity levels. He’s since switched to passive atmospheric packaging, which utilizes increasingly popular technology to keep humidity—and sustainability—in mind. “The buckets weren’t letting any moisture out. On top of that, you can imagine how much room 165 five-gallon buckets takes up in a grow space,” Hedrick says.

The same goes for long-term storage. With humidity-controlled bags, operators can rest assured that their product will maintain its efficacy, because as soon as that pack is sealed, the humidity level is guaranteed to stay the same.

Cannabis brand Lava Leaf Organics relies on passive atmospheric packaging for efficient storage—mainly because of the reduction in carbon footprint and increase in terpene preservation.

“When we think about the energy involved in packaging and shipping large amounts of heavy glass jars compared to TerpLoc bags, it was an easy decision for us,” said Lava Leaf Organics CEO Tony Martinez.

“The bags are recyclable, and compared to glass jars with child-resistant lids, they’re much better at preserving terpenes. Using sustainable packaging allows us to put our best foot forward and to better control our customer’s brand experience.”

Tips for making sustainable storage work for you

Sustainable storage is an environmentally-responsible move for the cannabis industry to make, but when weighing the pros and cons of a big switch like this, operators should also keep in mind how positively it will impact their end product, consumer’s experience, and, subsequently, their industry-wide reputation.

Some product packaging examples in the market today

Placing your products in eco-friendly bags is just the start. There are definitely more tips and tricks operators can take advantage of to prolong the use of sustainable materials and ensure they’re leaving as small a footprint as possible. For example, Hedrick’s team reuses their passive atmospheric packaging for maximum efficiency—especially when it comes to bulk storage or curing.

“We mark all of our storage bags with the original strain, so we can reuse that bag for the same strain as long as it passes testing along the way. When I do so, I take a mixture of SaniDate and water to make sure everything is sanitized and clean,” Hedrick said. “That allows me to reuse them for about 3-4 months’ worth of curing and storage. You can reuse a bucket in that same way, but when it’s time to replace it, you’re still spending another $15-$17.”

Sustainable, humidity-controlled packaging is also ideal for testing consistency. If you send in five buckets of the same strain to be tested, you run the risk of them all sitting at wildly different humidity levels, which means some might pass, and others might be rendered trash.

All of the environmental benefits aside, using sustainable packaging just makes cents—literally. “Essentially, I’m saving a minimum of half a million in packaging every year. That’s my entire staff’s salary for two months. That’s incredible, impactful, significant savings that can make a huge difference for a business trying to expand.”

Too Many Cannabis Firms Put Sustainability in Last Place

Cannabis has long been considered a green industry by the masses.

As a standalone item, the cannabis plant is very environmentally friendly. This is particularly true when it comes to hemp, a variety of the cannabis plant with a huge range of environmental benefits. An extremely versatile and robust crop, hemp uses far less land and water than other common crops and even captures carbon dioxide and regenerates soil. Approximately 20,000 products can be made from its seed, fiber and flower, from biodegradable plastics to food supplements, meaning all in all – it is an environmentally and economically sustainable crop

Yet as with most things, when cultivated in mass, the cannabis plant isn’t quite so green anymore. With its high demand for water, land and artificial lighting, cannabis cultivation can actually leave a large environmental footprint (this does however, pale in comparison to the food industry).

What’s more, many firms do not properly understand how to correctly treat and apply chemical fertilizers and pesticides, and use a machine gun approach to growing their crops. This can result in unnecessary bleed waste, which in turn can kill micro-organisms and contaminate soil, water and other vegetation. Packaging has also been cited as particularly environmentally unfriendly in the cannabis industry, with several organizations using single use plastic for their products, due to the strict guidelines attached to packaging products of a medical or pharmaceutical nature.

A field of hemp plants, (Cannabis sativa L.)

So as the CBD, medical and even adult use cannabis industries become increasingly commercialized across the globe, there is risk cannabis might start moving in the wrong direction when it comes to sustainability.

Still relatively new, the cannabis sector is nascent and exciting, with the global cannabis market size valued at $10.60 billion in 2018 and projected to reach $97.35 billion by the end of 2026. Yet as the industry grows, so too will its footprint.

I’ve seen it first-hand. The industry being hugely competitive, so for companies vying for precious investment and fighting for a spot on the stock market, often, sustainability is the last thing on their minds. In my opinion, this is wrong. Not only morally – we all play a part in looking after our planet – but it’s also a poorly calculated business decision.

It’s no secret sustainability and ESG have become a hot topic when it comes to investing. Just yesterday, Credit Suisse told CNBC that the pandemic has accelerated the trend towards sustainable investments. The bank has even introduced an exclusion strategy whereby those investing can actively exclude controversial sectors.

So with the environment firmly on investors’ minds, cannabis firms need to realize that actually, if they want to secure the support of forward-thinking shareholders, they need to consider more than just the bottom line and truly take the sustainability of their operations into account.

Outdoor growing can require less energy inputs

Luckily, there are practices which cannabis cultivators can take on board to reduce their environmental footprint. To start with – growing outdoors. This enables cannabis farmers to harness the sun’s natural power, saving them money on electricity bills and increasing energy efficiency. With cannabis being a rather thirsty plant, water use is also a major concern – although this is nothing compared to the amount of water used by cotton plants. However, it is in fact possible to design indoor operations which recycle close to 100% of the water use, including capturing the perspiration from plants – at AltoVerde this is something we are looking to implement in our upcoming Macedonian sites.

Firms keen to improve on sustainability should also cultivate in a way in which soil is fully replenished and repaired after use – this is called regenerative farming, and it’s extremely effective for maintaining and improving soil quality, biodiversity and crop yields. Another interesting concept is the use of hemp. Some farmers have started using hempcrete – a concrete-like material made from harvested cannabis plants. As if the recycling aspect wasn’t good enough, hempcrete is actually carbon negative, meaning the production of hemp for hempcrete removes more carbon from the atmosphere than it produces.

It’s been incredibly exciting to be a part of the cannabis industry and I am excited to watch its growth in the years to come. It’s taken hard work for the sector to improve its traditionally poor image and to be accepted across the globe, so now, cultivators must lead by example and stop industry from being branded as one which pollutes. By transitioning to more environmentally sustainable practices, firms will be doing their bit for the planet, attracting the investors of tomorrow and ensuring their own success for years to come.

Is Your CBD Product Verifiably Natural?

Natural product analysis using Carbon-14 is a valuable scientific tool that can be used to confirm the naturality of cannabidiol-based (CBD) ingredients by verifying the percentage of a product that is obtained from naturally-sourced ingredients. Determining the percentage of biobased content in a product allows companies to ensure their CBD ingredients are truly natural-derived, identify the presence of synthetic adulterants, and authenticate marketing and “natural” labeling claims.

Why consider natural product analysis using Carbon-14 to validate your natural CBD products?

Carbon-14 is an isotope present in naturally-sourced materials. Natural product analysis measures the percentage of Carbon-14 present in an ingredient or product. Higher percentages indicate that a product is primarily or completely made with natural-sourced ingredients as opposed to synthetic, petroleum-derived alternatives. These cheaper, synthetic alternatives created from petroleum-based sources cannot be measured using Carbon-14. A product that is all-natural and completely plant-sourced will show a result of 100% biobased content whereas a low or zero percentage will reveal a product that is partially or completely formulated with synthetic adulterants.

The structure of cannabidiol (CBD), one of 400 active compounds found in cannabis.

Why should you be concerned with verifying the naturality of your CBD products? In recent years, the popularization of CBD extract has increased its demand as an ingredient in personal care and cosmetic products. Higher costs associated with the use of natural CBD extract instead of artificial extracts leads to the use of adulterated ingredients by some manufacturers or false label claims that a product is natural when it is not.

How can you prove your products are the real deal and ensure your customers are sure they’re getting the natural ingredients they expect? Artificial ingredients derived from petrochemical sources do not contain any carbon-14 content. The results of natural product analysis reveal the percentage of a sample that is procured from natural sources, allowing manufacturers and quality assurance teams to confirm their CBD ingredients and products are not synthetic or adulterated and to strengthen claims that their product is truly natural-derived.

Natural product analysis can authenticate the natural content of your CBD products. Validating naturality with Carbon-14 testing strengthens label and marketing claims and confirms your products and ingredients are completely natural and do not contain cheap synthetic adulterants. By verifying the percentage of our product that comes from natural sources as opposed to artificial, petrochemical sources, you can guarantee your product is genuinely made with natural CBD extract.

According to a press release, Drug Plastics & Glass, a packaging company that specializes in cannabis bottles and closures, announced new tools for their customers to calculate their carbon footprint. The company launched six new sustainability calculators with the goal to help their customers get more informed about their carbon footprint.

According to Jeff Johnson, director of marketing and business development for Drug Plastics, they want to show how small, incremental changes can have a lasting impact on a company’s environmental sustainability.“From switching to more eco-friendly resin and eliminating flame treatment, to calculating the savings gained from choosing PET plastic over glass, or eliminating collateral packaging, these calculators show how making simple changes can have a big impact on the environment,” says Johnson.

Here are some of their sustainability calculators they recently launched:

  • PCR PET Resin Sustainability Calculator: Reduce greenhouse gases by making new products from PCR PET removes plastic from the environment by converting PET plastic discarded by the consumer back into resin that can be used again.
  • Flaming Elimination Calculator: Conserve fossil fuels by opting out of the flame treatment process traditionally used to ensure water-based adhesive labels and silk screening would adhere properly to HDPE, LDPE, and PP bottles. Today, this is not always necessary.*
  • Bag Reduction Calculator: Determine the individual savings when you move to single bagging instead of double bagging bottles and closures inside the carton.
  • Concentrate Elimination Calculator: Switch from white pigmented bottles to those made with resin in its natural color state and eliminate CO2
  • Glass to PET Conversion Calculator: PET requires less energy to produce and saves on transportation costs.
  • Glass to HDPE Conversion Calculator: See the sustainable improvements in weight, transportation costs, and durability when you use HDPE instead of glass.

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

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

The European Green Deal and Circular Economy Action Plan

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

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

How Hemp Could Help Europe Achieve Neutral Emissions

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

Image: National Hemp Association

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

Watching Europe with an Eye on Regulation and Liability Risks

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

Hempcrete blocks being used in construction

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

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

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

 

From Produce to Cannabis: The Future of Indoor Agriculture

Throughout the United States, a majority of cannabis for medical and adult use is grown indoors, which requires a tremendous amount of energy and is generally inefficient. State regulators and cultivators alike are beginning to notice the benefits of greenhouse and outdoor-grown cannabis, primarily for energy efficiency and environmental sustainability.

Terra Tech, a publicly traded company, cultivates environmentally sustainable produce through its subsidiary, Edible Garden, in Belvidere, New Jersey. Utilizing Dutch hydroponic cultivation methods, integrated pest management and computer-controlled automation, Edible Garden grows certified organic herbs such as thyme and basil in their greenhouses in New Jersey.

Edible Garden is certified by the Global Food Safety Initiative (GFSI), which provides internationally recognized benchmarks and guidance for managing food safety and meeting standards. According to Ken VandeVrede, chief operating officer of Terra Tech, the company plans to take these cutting-edge practices and standards from cultivating produce to the cannabis industry to grow quality, sustainable and safe cannabis in states where it is currently legal.

The company is actively making its operations more environmentally sustainable via greenhouse cultivation, Dutch style hydroponics, shipping locally, and integrated pest management. “We plan on implementing guidance from our two years of GFSI certification and our organic certification along with all of our practices from the food side and bring them to cannabis; for us, it is just another plant,” says VandeVrede. With the help of computer automation, he says they can cultivate cannabis at the commercial scale, creating more homogeneity by removing human elements and utilizing environmental controls. Through computer automated blackout curtains in their greenhouses, they plan to minimize energy usage by using natural sunlight when possible.

“The procedures are very similar across industries so we are creating our own internal standards for cannabis cultivation,” says VandeVrede. “We are trying to be at the forefront of the industry and set the standard for growing cannabis, because right now, there are no standards in place.”

Terra Tech has already started its move into the cannabis industry via its subsidiary, IVXX LLC, which makes medical cannabis extracts for dispensaries in California. The company has also broken ground on cultivation and production facilities in Nevada and dispensaries in California, and submitted an application for licenses in Maryland. “Terra Tech is doing everything with vertical integration in mind; we will control the cultivation, bringing experience from our agricultural background to cultivate high quality and high yield cannabis, making oil and extracts with it to sell in our dispensaries,” adds VandeVrede.

Looking to the future of cannabis cultivation, Terra Tech’s plan is to keep environmental sustainability at top of mind. “As a company we are growing indoor, but moving toward greenhouse cultivation across the board”, says VandeVrede. “Our focus on expansion will be [include] greenhouse-grown cannabis, which is a lot more efficient, saving us money but more importantly reducing our overall carbon footprint.” With more companies adopting these sustainable farming practices, the industry might soon usher in a new era of environmentally friendly cannabis cultivation.
