Our story
Specialized Systems
The equipment requirements of the cannabis industry are very specific and rapidly changing based on new innovations. Green Process has identified the need for highly customized efficient refrigeration systems which address a major bottleneck in the processing of cannabis and hemp based concentrates. After several design iterations we have designed, tested and put into service a product suite which ranges in size from boutique scale small batch extraction operations to publicly listed companies.
Our philosophy
A Proven Approach
Our strategy builds off proven and well documented extraction and processing methods with increased efficiency and scalability, while minimizing technical risks. Other systems operate at -40 Deg C, while GPS systems are designed to reach as low as -60 Deg C at full throughput with impressive results.

Our Team
Our team has extensive experience in extraction, technology development and the technical and legal aspects of project management.

Viggo Hansen
Principal – Research & Engineering
Viggo holds two patents in chemical processing and combustion systems developed at the University of Washington and generally posses a broad range of experience with engines, propulsion and energy systems. Viggo led the UW sounding rocket team from 2011-2012 where he developed an efficient rocket engine from scratch. Since 2015 Viggo designed and built several hydrocarbon extraction systems which passed peer review, and worked with a major civil engineering firm to develop a novel modular C1D1 extraction lab.
