Our Process

1) ANAEROBIC DIGESTION

The GPS Anaerobic Digestion line of business involves processing organic waste streams at GPS owned/operated facilities to produce on-site energy in the form of biogas, electricity, and solid residues that are suitable for use as a soil fertilizer.  GPS anaerobic digestion facilities would produce biomass energy that is dependable, economically competitive, and environmentally sustainable.  As currently envisioned, GPS is developing AD facilities in two sectors: agricultural waste processing and wastewater treatment.

Complete Mix Digester:
A complete mix digester is an enclosed, heated tank with a mechanical, hydraulic, or gas actuated mixing system.  Complete mix digesters generally work best when there is dilution of the excreted manure with water.  Wastewater captured from other on-site processes may often be reused to serve this purpose (e.g., milking center wastewater).

Additional digester types:
Several other digester types have also been deployed in agricultural projects in recent years, including induced blanket reactors, fixed film digesters and batch digesters.

 

2) BIOFUEL FEEDSTOCK REFINING

The GPS Biofuel Feedstock Refining line of business involves collection and processing of material at GPS owned/operated facilities to produce a refined “brown grease” product that is a direct input to renewable biofuel production.  Within the past five years, there has been a boom in worldwide demand for next generation biofuels and renewable electricity, with this demand being driven in part by legislation promoting Renewable Fuel Standards (RFS) and/or the Renewable Portfolio Standard.

Each GPS grease refining facility is designed to handle 300-500 tons/day of process sludges, food residuals, and waste oils, or 100,000 to 160,000 tons/year (assuming an operations profile of 6 days a week, 52 weeks a year).  To handle this volume, the process requires, as other inputs, sulfuric acid, caustic soda and process water.  Below are the unit operations in the process (all based on commonly known industrial practices):
