A set of anerobic digestion facilities are proposed for North Carolina. The facilities will digest hog manure and food/biomass waste while using the resulting methane to generate electricity, most likely using reciprocating engines.
Widespread large-scale digestion for animal and biomass wastes is a fairly new concept in the United States, though it has been practiced in many areas of Europe for quite some time due to less access to cheap fossil fuels and stricter regulations on the disposal of wastes.
