Patent for Method Removing Pesticides from Cannabis Oil Filed

The new method could end health concerns currently facing the legal cannabis industry.

These days, the world of cannabis is moving decidedly in the direction of concentrates. Whether it’s dabs or vape pens, it’s clear that concentrates are the next big thing in weed.

And this transition is creating all sorts of new opportunities and possibilities. At the same time, it’s raising a number of new questions about the best way to produce high-quality concentrates.

Recently, a scientist working at cannabis company Capna Labs filed a patent for a new method aimed at removing potentially harmful pesticides from cannabis plant matter.

According to the patent application, this process would ultimately be used to improve the process of extracting cannabinoids in order to make high quality THC oils and concentrates.

Patent Filed for New Pesticide Cleaning Process

The patent for the new cleaning process was officially filed earlier this month, on April 4. Specifically, the patent lists Capna Inc., a cannabis lab company, as the applicant. And Edwin Sibal, Chief Development Officer at Capna Technologies, is listed as the inventor.

According to the patent application, the new process uses bentonite to remove a number of pesticides from cannabis plant material. As explained in the patent application, the use of bentonite is central to the new process.

Further, the process being patented by Sibal and Capna Technologies is supposed to provide a new and improved way of stripping potentially harmful pesticides out of the cannabis plant material that is then used to make oils and concentrates.

In particular, the patent application claims that this new process of using bentonite could solve problems that current extraction methods cannot address.

“Plant matter, including cannabis plant matter, may contain contaminants such as pesticides, microbes, and heavy metal,” the application says. “Pesticides are not effectively removed by ethanol extraction alone, or using butane extraction alone, or using carbon dioxide extraction alone.”

As stated in the patent application, the new process of using bentonite “addresses the unmet need for removing pesticides from plant matter . . . by novel methods that use bentonite.”

Cannabis and Pesticides

In recent years, the use of pesticides, fungicides, and fertilizers has become an important issue in the legal cannabis industry.

Specifically, there are growing concerns and worries over the safety of many of the chemicals commonly used in the cultivation and production processes.

Many times, these chemicals end up contaminating the final product, whether it’s flower, edibles, concentrates, or some other type of cannabis product.

These contaminants can be unhealthy and harmful to consumers. But it’s not just human health that is at stake. Often, these chemicals also harm the environment.

In some cases, chemicals used during the production process poison local wildlife. Similarly, they can leach into water supplies. And when that happens, it can spread toxins throughout larger regions.

More and more, states are trying to clamp down on the chemicals being used in the cannabis industry. For example, states like Colorado and California have put into place stricter rules.

Typically, these rules dictate what can and cannot be used in the production process. Similarly, other rules require more rigorous lab testing requirements to ensure that contaminants do not get through to consumers.
