Our customers realize cost savings and generate revenue by using biogas as clean energy. In areas with high waste management fees, waste disposal fees can be reduced. Further, digestate (material remaining after anaerobic digestion) provides value as a fertilizer, compost, or as a high-quality organic product.

Biogas from anaerobic digestion can be combusted in a combined heat and power unit (CHP), producing renewable heat and electricity. Biogas alternatively can be upgraded to renewable natural gas (RNG) to be used as a vehicle fuel in the form of compressed natural gas (CNG) or liquefied natural gas (LNG), or injected into the natural gas pipeline grid.

In addition to anaerobic digestion systems, BIOFerm offers biogas upgrading and gas-to-grid injection as North America’s exclusive provider of the Carbotech Pressure Swing Adsorption (PSA). These systems utilize PSA technology to scrub raw biogas (from AD systems, landfills, municipalities, wastewater treatment plants, agricultural operations, etc.) and upgrade it to RNG for pipeline injection, or for use as fuel in the forms of CNG or LNG.
