What is biogas and how is it produced from manure?
Biogas is a renewable energy source produced through the decomposition of organic matter in the absence of oxygen. When manure undergoes anaerobic digestion, a process where microorganisms break down the organic material, biogas is released. This biogas primarily consists of methane and carbon dioxide, with small amounts of other gases like hydrogen sulfide and ammonia.
To produce biogas from manure, the organic waste is collected in a sealed anaerobic digester. Within this controlled environment, bacteria break down the organic matter, releasing biogas as a byproduct. The biogas can then be captured and utilized as a sustainable energy source for heating, electricity generation, or even as a vehicle fuel. This process not only helps in managing manure waste but also reduces greenhouse gas emissions and lessens reliance on non-renewable energy sources.
