High Plains Bioenergy/Seaboard Foods Gas Uprgrading

High Plains Bioenergy/Seaboard Foots

High Plains Bioenergy (HPB), a subsidiary of Seaboard Foods and major North American food processor, installed a Carbotech Pressure Swing Adsorption (PSA) gas upgrading plant from BIOFerm Energy Systems in 2017 to generate renewable natural gas (RNG) for pipeline injection.

HPB traditionally fueled boilers with the gas generated from anaerobic digestion of pork processing waste, but identified gas upgrading and grid injection as a sustainable, alternative use for their gas to enable the highest return.
