COMBINED LIQUID TO SOLID-PHASE ANAEROBIC DIGESTION FOR BIOGAS PRODUCTION FROM MUNICIPAL AND AGRICULTURAL WASTES

摘要

Disclosed embodiments employ an integrated anaerobic digester which converts a mixture of digestion effluent from a liquid anaerobic digester and a solid organic material (e.g., a lignocellulosic biomass, food waste, agricultural waste, etc.) to a biogas. In various embodiments, the effluent of liquid anaerobic digester may be used as a nitrogen source and inoculum for solid state digestion.
