Hemp-Based Plastic Shows Promise As Environmentally Friendly Alternative To Traditional Packaging Materials, Study Finds

CBD is widely used for personal wellness. In the not so distant future, it could be used for the well-being of the environment.

By Phillip Smith, American Hemp Monitor

Many of the ubiquitous plastics we use for everything from water bottles to food containers to substrates for flexible electronics are made from petroleum-based materials such as polyethylene terephthalate (PET), which not only consume large amounts of fossil fuels, but also break down into tiny particles called “microplastics.” These particles leach chemicals, including PET, into the air, water and food, and are linked to inflammation and cell damage.

Hemp, or more specifically, the hemp-derived cannabinoid CBD, may offer a viable alternative. In a recent study published in the journal Chem Circularity, a team of scientists and engineers demonstrated a hemp-derived thermoplastic that can stretch 16 times its original length. The material has a high “glass transition temperature,” a quality that allows plastics to remain dry and durable when boiling hot water.

Scientists have been looking for green alternatives to PET, but most plant-based polymers cannot match hemp’s glass transition temperature and are more expensive to produce. Additionally, the production of bio-based plastics typically requires high-temperature catalysts, and large-scale production is impractical due to challenges in catalyst removal and final product purification.

“Few plastics made from natural resources have this quality,” they said. he said Gregory Sotzing, analyze author and professor in the UConn Department of Chemistry.

“Today’s polycarbonate is made with bisphenol-A, a known endocrine disruptor. The hope here is that cannabidiol (CBD) will replace the bisphenol-A found in today’s processed plastics,” he added.

“Our work has established CBD-based polycarbonates as a sustainable replacement for used thermoplastics such as PET,” said co-author Mukerrem Cakma of Purdue University. “We have developed a rigorous processing science framework that combines molecular architecture with melt processability, orientation development and extensibility without compromising manufacturability.”

To compete with PET, substitutes need medium- and high-temperature stability and melt processability, or the ability to easily melt, deform and shape a material, which the team has achieved for the first time in a hemp-based polycarbonate. To do this, by testing the processing parameters that provide the appropriate structure and properties for wide use and establishing guidelines for the industrial processing of the material.

“This polycarbonate, as a smooth film, has a very high contact angle with water. We didn’t expect our polyCBD-carbonate to have a higher contact angle than most polyolefins,” Sotzing said, adding that materials with this property could be used as nanoparticles for drug delivery and catheter coatings.

And they can be recycled.

“We can chemically recycle it with a base, where the polyesters can be depolymerized using a base to break them down to the starting materials. We don’t need enzymes,” Sotzing said. “What happens is it will hydrolyze or break the polymer chain, and the CBD can be recovered.”

There is currently not enough CBD produced worldwide to completely replace PET for plastics, but that only means that more hemp would need to be grown to supply the demand when it emerges. It would be one more application of this incredibly versatile plant that already provides oils, fibers, seeds and cannabinoids, intoxicating and otherwise.

“We came together on this project to try to replace conventional petroleum-based plastics with something found in nature. We’re finding new ways to use the whole plant. That’s what was done with oil, because they found a way to use every little drop, even down to the sludge that turns into asphalt,” Sotzing said. “Now, we’re doing that with hemp as well. There’s a lot of useful things inside that plant.”

We don’t really deal with a lot of mites because of our IPM program

Published

Flora Farms Pest Management Program it is built to reduce to nothing depending on the harvestso the plant ends up clean. Luke Allenbrand, Flora Farms’ crop leader, leads an integrated pest management program that focuses on prevention. “We don’t honestly deal with a lot of mites because of the IPM program, because of the predatory mites that we’ve put down as a precaution,” says Luke. “It allows us to have a much cleaner garden in the back half.” Preventative work keeps spray volumes relatively low because the curative side of the program rarely needs to be heavy.

“Actually, we are at the lowest number of these sprays that we have. The milliliters that we are using are numbers that do not exist to be a prevention,” says Luke. “But as soon as you see an uptick of those mites or anything, we bring it up to a therapeutic amount, which is still a small milliliter. And as long as you’re on a fast track with it, you see them disappear within 10 days.” The targets are spider mites, which feed on the plant’s THC and terpene production and degrade the flower.

Tested solutions
The three products used by the company are derived from agricultural and food use. “We actually apply about three insecticides that are very common around the agricultural and food grade of these products, using a suite of IPM, Venerate and Grandevo, insecticides that will deal with these mites,” says Luke. The application is intermittent rather than constant. “We usually use a 5-day spray cycle so we can have rest periods in between, so it’s not just a consistent density of that spray,” says Luke. He sees progress against mites in the gaps between the successions.

However, at some point, the spraying stops. “We finish the spray cycle by day 40. We usually don’t want to spray anywhere after day 40. At that point, you’re going to damage the product,” says Luke. “And at that point, we’ll put predatory mites in. It really helps us get to that final push point by day 59, 60 of that harvest. So we actually have a lot less of our spray in that late period. So it’s a much better tasting product.” Predatory mites take over the job of spraying, leaving nothing on the flower.

Biological control
Biological control has two forms. “We usually use them, they’re called crazy mites, and honestly, it’s crazy to see,” says Luke. “Actually, I’ve seen some of the ones in a close-up photo kill a bug, some of the cocoons actually drive away, and even attack the spider mites themselves. Very beneficial. Callias are also slow. They’re little bags that we hang on plants and they’re very beneficial to us.” Different predators work at different speeds, which is why the program runs more than one.

Missouri’s testing regime is the context in which growers operate. Each plant is tested for pest control chemicals and must pass before the product goes ahead. “Other crops and other black market shops or smoke shops in Missouri don’t have to worry about the testing we have to do,” Luke says. “Everything we use here is natural. Each of our pest management is a lot of essential oils that fight these mites. Everything we would put on a plant is food grade.” The test covers foreign chemicals, heavy metals, and anything else that an unregulated supply should never consider.

The whole arc is from biology to chemistry and back to biology. “We go from predatory mites to a food-grade spray regimen, and then back to predatory mites at the end. That way, these plants will have time to finish with no chemicals, nothing,” says Luke. “The rest of that life cycle, about 15 to 20 days, is the most natural it will have. No spraying at all during that, just to push predatory mites off that end, so there’s no residual mite damage on those plants.”

California Bill To Legalize Marijuana Dispensary Drive-Thru Windows Advances In Senate After Clearing Full Assembly

Published

By

It has been passed by a California Senate committee and passed by the Assembly bill that would allow marijuana dealers to offer car windows to serve customers.

The measure, which cleared the Senate Business, Careers and Economic Development Committee on a 7-3 vote Monday, says licensed cannabis retailers and micro-businesses with storefronts can sell marijuana products “in a motor vehicle to a customer in a drive-through located on the premises.”

Under Assemblywoman Gail Peller’s (D) AB 2697, cannabis businesses would need permission from the local jurisdictions in which they operate to add a drive-thru.

The sponsor told committee members before the final vote that the bill will “expand access to legal cannabis products while strengthening our ability to compete with the illegal market.”

Annie Aubrey of Chuck’s Wellness Center, a retailer in Placerville, testified that the legislation is “about improving access.”

“A large portion of our customers use cannabis as medicine, including seniors, veterans and people living with chronic conditions that affect mobility, the population that this regulated system seeks to serve,” he said. “For many, even simple tasks like getting out of a vehicle or navigating a retail space can be physically difficult or prohibitive…A drive-thru option removes that barrier, giving patients and consumers access to what they need in a way that’s dignified and consistent with their healthcare needs.”

Amy O’Gorman Jenkins of the California Cannabis Operators Association said the legislation will provide “operational flexibility” in a highly regulated system.

“It doesn’t expand who can access cannabis,” he said. “It allows retailers, with local approval, to serve existing patients and customers more efficiently.”

Jenkins also argued that this measure could improve security.

“Currently, road traction transactions are already allowed. This means that workers regularly have to leave a safe premises while transporting the product, and sometimes they have to deposit cash in parking lots,” he said. “AB 2697 provides an additional mechanism for obtaining product, but requires a fixed and secure transaction point, keeping employees inside and reducing exposure to theft.”

Pellerin, the bill’s sponsor, previously said that “California cannabis retailers lack a common and accessible transaction channel for consumers that so many other retailers in California offer, including fast food, pharmacies, banks and even liquor stores.”

“Cannabis consumers with mobility issues or other disabilities have limited options for obtaining cannabis without having to get out of their vehicles. And while home delivery is legal, there are restrictions on service areas,” he said. “Allowing cannabis sellers to add a secure ride option, if allowed by their local jurisdiction, will improve the consumer experience, increase the security of cannabis sellers and help expand California’s legal cannabis market.”

The California Association of Narcotics Officers opposes the proposal, however, as a representative, Ryan Sherman, testified that it would make it more difficult for dispensary workers to check the IDs of customers who are of legal age or to spot signs of current intoxication at drive-thru windows.

“This bill prioritizes speed of sale over public safety while undermining existing protections designed to prevent illegal sales and protect public safety,” he argued.

Under current policy during the COVID pandemic, dispensaries can already offer street pickup.

The invoice that moving forward in the legislature would mandate that auto sales “be made through a fixed panel security window with a security drawer or similar secure transfer mechanism that is part of a building located within the premises.”

California regulators recently approved emergency rule changes to the state’s marijuana licensing process. to make it easier for companies to receive benefits In line with the Trump administration’s latest move to federally regulate medical cannabis.

While Gov. Gavin Newsom (D) recently He took credit for helping lead the state’s push to legalize marijuana and discussed his limited experience with cannabis use.

In October, however, Newsom vetoed a bill that would have It allowed micro-marijuana companies to ship medicinal cannabis directly to patients Through common carriers like FedEx and UPS, he said the proposal would be “too burdensome and complex to manage.”

Newsom signed a bill earlier this month streamlining research into marijuana and psychedelics.

In September, the governor also signed a measure pause on the recent tax increase on marijuana products.

Separately, the state attorney general says Indian tribes cannot independently participate in the marijuana trade with licensed cannabis businesses without obtaining their own commercial license from state officials.

California officials have recently been rewarded nearly $30 million in grants for marijuana-focused academic research projects.
