Bio Gas Production from Municipal Solid Waste

Abstract

Wherever there is human habituation, municipal solid waste is produced, which consist mainly of household food waste, agricultural waste, human and animal waste. For each year the amount of produced municipal solid waste is increasing dramatically. Breakdown of organic materials in the absence of oxygen produces methane. The process is known as anaerobic digestion and performed through the biological activity of microorganisms. The rest product contains also a high amount of nutrients that can be used as a natural fertilizer. The objective of this experiment is potential of biogas (methane) production from municipal solid waste. The digester operated used in this experiment is plastic barrel; the experiment was performed with mixtures of cafeteria waste. The mixture with different combination of faba bean, bread, vegetables, fruits, fishes and meat wastes was an-aerobically digested in reactors. The results of this experiment indicate that there is potential of bio-gas production from the municipal solid waste.
