Manure and slurry are often used as feedstock for biogas production in a biogas digester. The biogas digestion process involves breaking down organic matter in the absence of oxygen, producing biogas containing methane and carbon dioxide. The biogas produced can be used to produce electricity, heat, fuel and other products.

The advantages of using manure and slurry in a methane digester are numerous. First of all, it allows these organic wastes to be recovered by producing renewable energy. Manure and slurry are often considered as polluting wastes that are difficult to treat, but their use in a methane digester allows them to be transformed into a valuable resource. Breeders have a particular interest in recovering them, since they are produced continuously by their breeding activity.

Producing biogas from manure and slurry helps reduce greenhouse gas emissions. In fact, methanation captures the methane produced by the decomposition of organic matter and transforms it into a renewable energy source, thus preventing its release into the atmosphere.

Using manure and slurry in a biogas plant can help reduce waste disposal costs because, rather than having to pay to spread these products, farmers can use them to produce energy.

The disadvantage of these products is their low biogas content and therefore their low methanogenic power. However, they provide stability to biology with an organic composition ideal for the development of bacteria in an anaerobic environment.
