Willow Industries

What We Do

Willow Industries offers post-harvest microbial decontamination. Based in Denver, Colorado, we provide state-of-the-art technology to clean and purify flower and trim.

Our ozone-based patent-pending technology, WillowPure, reduces yeast, mold, bacteria, Aspergillus, coliforms, E.Coli, and Salmonella, all the while protecting the medicinal properties of the plant.  Most importantly, we deliver a finished product that is safe for consumers.

Willow Industries has successfully passed hundreds of
microbial tests and saved thousands of pounds of product.

Our Team

We are a team driven by a desire to set the standard for health and safety in an emerging industry intent on not simply legalization, but legitimacy.

Our background in operations, marketing, sales, and science, along with our presence in public policy, underscore our understanding of the challenges we face as an industry and our ability to find solutions to propel us forward.

Safety and Regulatory

We believe working in tandem with state regulatory agencies that govern the cannabis industry provides transparency to our customers and state investigators. It mitigates surprises during inspections and keeps the WillowPure process in compliance. In doing so, we look to have our technology and WillowPure system reviewed and approved by state specific regulatory agencies. The states below have either provided us a registration, verbal approval, and/or do not govern devices.
