A review of methane production from agricultural residues in China

Anaerobic digestion is an effective technology for resources recycling. The application of anaerobic digestion has been a hotspot due to its capability of converting solid organic waste into methane. The metabolism of acetoclastic methanogens, anaerobic digestion features and strategies of three main agricultural residues and current situation of large, medium biogas plant built in China are summarized, hoping to promote the application of this technology to deal with agricultural residues. Also, the current problems are presented and future research and development of biogas technology are proposed.
