The biogas production uses the process of anaerobic digestion to turn management of organic waste and feedstock, such as plant, dairy manure, food waste, and municipal solid waste, into valuable biogas containing energy, and other revenue opportunities like fertilizer products.

Biogas is composed of roughly 50-70 percent methane, 30-40 percent carbon dioxide, and typically contains a range of other impurities, such as, Hydrogen sulphide (H₂S), various VOCs such as siloxane, pinene limonene and terpenes.

Removing gaseous and odorous trace compounds via biogas filtration, is a nessecary step to generate biomethane of sufficient purity to be suitable for grid injection and to prevent damage to combustion turbines and reciprocating engines.

Activated carbon filtration is one of the most commonly used and successful treatment methods to remove contaminants and help upgrade the methane yield and abate odor problems.
