Methane from anaerobic fermentation [Biogas]

Conventional anaerobic digestion is an established technology for wastewater stabilization, but methane production rates and net energy yields are generally too low to make the process competitive as a source of methane. Numerous improvements are being developed to make conversion of plant biomass t...

Zusammenfassung:	Conventional anaerobic digestion is an established technology for wastewater stabilization, but methane production rates and net energy yields are generally too low to make the process competitive as a source of methane. Numerous improvements are being developed to make conversion of plant biomass to methane and simultaneous waste stabilization-methane production practical. Among these improvements are innovative digester designs and process configurations. Efforts to commercialize modern anaerobic digestion technology are progressing.
