Nutrients and energy from biomass for sustainable food production Nexus Bioenergy provides a one-stop solution for sustainable food production. Nexus builds and operates bio-refineries that recover energy and nutrients from waste biomass.Our process digests biomass such as food waste and livestock manure using both anaerobic and aerobic digestion in a compact, automated facility and produces a organic fertilzier and biomethane. We build and operate our biorefineries adjacent to food processing plants (meat packers, dairies, canneries, bakeries etc). We aim to work with large vertically integrated food processors (Dean Foods, Smithfield farms etc) to provide them with a waste disposal solution, savings on electricity and nutrient costs.
