Biogas Energy Production Potential of Grass under Anaerobic Digestion: Review

Abstract

Because of the recent increase demand of energy, interest in environmental issues and depletion of fossil fuel, the demand of renewable energy sources as substitute of fossil fuel is rapidly increasing. Production of biogas under anaerobic digestion as methane can be used to replace nonrenewable energy resources in both heat and power generation and as a vehicle. For biogas production various organic feedstocks are used. Most often used are animal manure, food waste, agricultural wastes and crop residues, aquatic waste, forest residues, municipal solid wastes and grass. The review is based on secondary data obtained through various sources such as textbooks, journals, documents and conference papers with the objective of providing an overview of biogas energy production from biomass, thus providing information toward anaerobic digestion contributing to methane rich biogas production. The review shows that biogas production from biomass as a good fuel alternative because the source biomass can be grown renewably and decrease environmental stress.
