Description of the SLM Technology

Short description of the Technology

Production of fuel and manure from animal waste

Detailed description of the Technology

People here use animal as well as human waste for the production of biogas.Equal amount of dung and water is poured in the inlet and mixed by the help of mixture.Then the raw materials are passed to the digestor where gas (methane) is produced by an anerobic fermentation by methanogenic bacteria. The produced gas is collected in dome and slurry is drained out through an outlet.

Purpose of the Technology: The biogas produced from the plant is used as a fuel for cooking food. The bio gas produced can also be used to light bulbs.The slurry can be used as manure in agricultural fields.

Establishment / maintenance activities and inputs: About 24% houses is using this technique by the funds from international , national (government) and few by self funding . The digester should be cleaned every five years of its use.

Natural / human environment: Temperature maintenance is basic requirement for biogas production. (36 degree celsius).
It is most favorable if the plant is near the water resources and near to the fuel source i.e. cattle house.
