New cannabis cold water extraction method proposed as safer alternative in industry

The Plymouth Zoning Board of Appeals convened on May 19, 2025, to discuss a proposal concerning a new cold water extraction method for cannabis products. The meeting focused on the safety and environmental impact of this extraction process compared to traditional methods such as ethanol, propane, and butane extraction.

The proponent of the cold water extraction method emphasized its health benefits, describing it as "solvent-less" and an ancient technique that is gaining traction in the industry. The speaker noted that while many manufacturers have invested heavily in older extraction technologies, the cold water method is expected to become the standard in the coming years, phasing out less environmentally friendly practices.

During the discussion, board members raised questions about the water usage involved in the extraction process. The proponent stated that approximately 1,000 gallons of water would be used monthly, with about 30 to 50 gallons utilized daily for the extraction. It was clarified that while the water is not reused after it becomes contaminated with chlorophyll, the process is designed to minimize waste and ensure non-toxic byproducts.

Concerns regarding waste management were also addressed. The proponent explained that any refuse from the extraction process would be securely stored and disposed of by an approved cannabis waste company, adhering to industry standards.

Overall, the board expressed support for the proposal, with members acknowledging the potential benefits of the cold water extraction method. The meeting concluded with a consensus that the proposal aligns with the town's goals for sustainable practices in the cannabis industry. Further testing and collaboration with local departments are expected as the project moves forward.
