BACKGROUND: Invented by two Ph.D. chemists and an expert distillation engineer, Catalytic Pesticide Removal (CPR) offers a revolutionary method to remove or reduce harmful pesticides in medical cannabis extracts and oils. The methods and science are proprietary and confidential; a patent is pending.
RESULTS: Analysis was performed by Sonoma Lab Works in Santa Rosa, CA using an Agilent liquid chromatography and a Sciex triple quadrupole mass spectrometer (LCMS/MS). We tested supercritical carbon dioxide extracts in both raw and distillate forms and produced significant reductions of pyrethriums, bifenazate (FloramiteTM), spiromesifen (Forbid 4FTM), spinosad, abametic (AvidTM), and myclobutanil (Eagle 20TM). Many tests have been performed and repeated. Several representative test results are shown here:
For myclobutanil, we achieved a 98% reduction:
Bifenazate also showed good reduction in many tests. A representative example:
We also observed similar positive test results for spiromesifen, spinosad and abamectin using a variety of methods. We expect proportionally lower values (below detection) with repeated treatments and equipment improvements. Limited test data shows little to no effect on potency. We are confident that this technology can also be used to remove heavy metals.
ESTIMATED MARKET VALUE: Current cannabis sales in legal states (OR, CO, and WA) is currently around $2.6B, not counting California (Ref 1). If California is added to these states, estimated sales would be around $7.4B based on population data (Ref 2). Of this, about 30% of sales are concentrates (19%) and edibles (12%) (Ref 1). Based on this, the estimated concentrates market portion is about $1.4B. It is estimated that between 65 to 75% of the extracts market is contaminated with pesticides, mostly myclobutanil (Ref 3). If we assume 65% contamination, this corresponds to an inventory worth about $900M and equates to a market value exceeding $10M per year. This application has far reaching worldwide applications, especially in other countries where pesticide regulations are not as strict as in the US. Additional financial details and market analysis are available by request.
LICENSING AND IMPLEMENTATION: We are seeking a well-established partner to assist us in bringing this important technology to the cannabis patients and the marketplace. We have filed a provisional patent and are looking for investment partners to accelerate the rollout of this technology in legal cannabis states.
Delta 9 Labs, LLC has developed a proprietary process for pesticide and heavy-metal removal from extracts derived from cannabis. Called Catalytic Pesticide Removal (CPR), this is the only high-volume, commercial process that safely removes harmful pesticide and metal residues without affecting the medicinal quality. A short white paper is attached above that describes results from our process and proof of US Patent filing noted below. We believe this adds significant value to the industry since contaminated flowers or trim can be converted to concentrates and treated with CPR, rather than be destroyed or removed from the market. Without this option, cultivators are at significant financial risk if their crop is lost to contamination and cannot be legally sold.
In the proposed regulation (CCR, Title 16, Division 42, Chapter 5: Testing Laboratories), we recommend the following additions:
§ 5313. Residual Pesticides
Part (c) If a sample is found to contain pesticides above the allowable amount listed in the tables in subsection (b), the sample “fails” pesticide testing. If the sample fails pesticide testing, the batch fails laboratory testing and may not be released for retail sale. The customer has the option to remediate liquid extract samples utilizing Catalytic Pesticide Removal (CPR) technology. If this option is utilized, the remediated sample shall be resubmitted to the testing laboratory to ensure the residual pesticides have been successfully reduced to the level below those shown in the table above.
§ 5328. Heavy Metals
Part (b) The laboratory shall report the concentration of each heavy metal listed in subsection (a) in micrograms per gram (μg/g) in the certificate of analysis. The laboratory shall report that the sample “passed” heavy-metal testing if the concentrations of heavy metals listed in subsection (a) are below the following heavy metal action levels. If the sample does not pass heavy metal-testing, the customer has the option to remediate liquid extract samples utilizing Catalytic Pesticide Removal (CPR) technology. If this option is utilized, the remediated sample shall be resubmitted to the testing laboratory to ensure the heavy-metals are below action levels in the table below.
