Advanced Processing Technology

Leveraging Thermodynamics and Nanotechnology

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.
