Biogas – Background
Biogas purification - Eliminating VOCs and siloxanes

The latter, made up of proteins, lipids and carbohydrates, is broken down by a biological process segmented into four chain reaction stages:

• hydrolysis;

• acidogenesis;

• acetogenesis;

• methanogenesis.

Methane production takes place during the final stage. Each of these involves different microbial populations, acting symbiotically within a bacterial consortium
