US (CA): Third-party study validates odor control solution

BioLargo announced that a third-party study had concluded its industrial odor control product CupriDyne® Clean eliminates “terpenes”, which cause the odors in cannabis grow and production facilities. "Conducted by Southern Air Systems Corp (SAS) out of Knoxville Tennessee, the study analyzed the two key odor-causing terpenes: myrcene and limonene.," the team with the company explains. "In business since 1989, SAS personnel have more than 60 years of combined experience exclusively providing air quality services to the power, petroleum and chemical industries. The study concludes,

“After treatment with CupriDyne Clean, no trace of terpenes was detected in the air samples.”

BioLargo President & CEO Dennis P. Calvert commented, “This is a momentous day for CupriDyne Clean. Although field trials had already demonstrated that it was effective against odors caused by cannabis cultivation, this data set represents crucial scientific validation that should accelerate adoption of the product by cannabis and hemp industry operators. Many of the major players in the cannabis industry are scientifically minded, and third party validated data sets like this are crucial to earning their business.” 

Terpenes are highly odorous volatile organic compounds (VOCs) produced in cannabis cultivation and processing, and are known hazardous air pollutants when present at high concentration. In many jurisdictions Cannabis growers are required by regulators to enact air quality control measures to mitigate odor-causing terpenes at their operations (such as in Los Angeles County). The predominant solution currently used by the industry is carbon-based filters, which are expensive to purchase, install, and replace, and are widely known to be inadequate for handling the high volume of terpenes produced by industrial cannabis cultivation facilities. In order to comply with regulations and maintain good relations with neighbors, growers and processors in the booming cannabis market are seeking better active solutions to managing terpenes.

Joe Provenzano, President of BioLargo’s wholly owned subsidiary Odor-No-More, Inc., commented, “CupriDyne Clean is sold by a distributor to the industry under the Cannabusters brand. These results increase our confidence in the product’s capacity to revolutionize odor control in the cannabis industry. Unlike many competitors, our product doesn’t just mask the odor-causing VOCs, it breaks them down through oxidation, meaning it is better at improving air quality. Our product is environmentally friendly, non-toxic, and not a pesticide, making it an attractive solution for the cannabis industry.”
