The present disclosure relates to a novel process to control odors from manure by digesting the manure into Methane. Embodiments may comprise a two stage anaerobic digestion process to digest the wastes and remove the nutrients from the wastewater. The initial anaerobic digestion is carried out in a closed vessel to capture any gassed released and otherwise proceeds as current practices are. The wastewater from the first stage digestion is then pumped into a second reaction vessel. This vessel reproduces the conditions that produce natural gas (methane) in the geologic setting, with high temperatures and high pressures.
