Biogas production technology
Journal Title: Applied Science Reports - Year 2013, Vol 1, Issue 3
Abstract
Present municipal solid waste landfills generate biogas and leachate. Due the amount of waste, biogas production represents a very promising way to solve the problem of waste treatment. Furthermore, the solid residuals of fermentation might be reused as fertilizers. Biogas is a fuel gas (CH4 and CO2 ) obtained by anaerobic fermentation of biomass like: manure, sewage sludge, municipal solid waste. Landfill gas is produced by wet organic waste decomposing under anaerobic conditions in a landfill. The whole biogas-process can be devided into three steps: hydrolysis, acidification, and methane formation. landfills gas production is dependant, on the degradation status of the waste material as well as moisture and temperature, all of which may vary greatly in different parts of the landfill body.
