Biogas Overview

Biogas is the production of methane through the digestion of mostly waste materials such as agricultural waste, food scraps or manure. Biogas is a widely used form of alternative energy in Europe and growing elsewhere.

SPR for Biogas

For biogas we have a specially designed version of the SPR called BioSPR.  Using cavitation the BioSPR offers the following benefits to biogas producers:


  • 20% or more increased yield
  • Decreased production time
  • Decreased viscosity
  • Decreased energy consumption
  • Use on many feedstocks
  • Commercial operating installs

Award Winning Technology

We've received Processing Magazine’s 2014 Breakthrough Product of the Year award.  The award recognizes technologies that made significant contributions in the process industries within the last year, and are expected to impact the industry for years to come.  Our biogas reactor makes the fats, sugars, proteins and starches more accessible to the bacteria which increases methane gas yield and can reduce viscosity.
