ANAEROBIC-DIGESTION OF HOUSEHOLD ORGANIC WASTE TO PRODUCE BIOGAS

Biogas may be readily obtained by the anaerobic digestion of organic w aste. If communities and towns could harness the energy which is conta ined in the organic waste which they presently dispose of in landfills or compost, this fuel could supplement or completely satisfy their he at energy requirements. Biogas production from household organic waste is rare because existing digesters are not suitable for small-scale a pplications. This paper describes a digester design which can make thi s waste to energy conversion process possible. The proposed digester i s inexpensive to construct and maintain, simple to operate and highly efficient. This is made possible by an integration of modem industrial digestion processes, and low-technology digestion concepts as seen in rural Chinese and Indian digesters.
