What is a bio-digester?
It is a sealed tank or container specifically built to provide anaerobic conditions for the breaking down of organic matter to produce biogas
What is biogas?
Biogas is gas produced from degradation/decay/decomposition of organic matter in the absence of oxygen (anaerobic digestion). It is typically composed of 60% methane and 40% CO2. It is similar to natural gas which is composed of 99% methane.
What feed is needed for a bio-digester?
Sufficient feedstock/waste (organic) preferably, cow dung or any other animal waste. For those who own dairy cattle, a minimum of two cows in zero-grazing unit would provide sufficient feedstock to qualify for a biogas plant.
What is bio-slurry?
Bioslurry is the liquid discharged at the biodigester outlet after gas has been tapped for energy. The biodigesters are fed daily with a mixture of fresh cowdung and water which is retained in the digester for a period of two to three months before being discharged as bioslurry. Some literature refer to it as digestate, sludge or simply slurry. Biolsurry is made up of 93% water and 7% dry matter. The dry matter contains Nitrogen (N), Phosphorus (P) and Potassium (K), which are the required nutrients for the healthy growing of crops.
