Biogas management from generation to transformation including recovery

The methane produced by the decomposition of organic matter in the absence of oxygen releases biogas, typically more than 50%. Tetra Tech is a recognized expert for optimizing generation, upgrading biogas, purification and use in order to produce electricity, renewable natural gas and heat.

These solutions are possible with a source such as a landfill of from anaerobic digestion. The technological solutions implemented by our firm allows the client not only to capture them, rather than letting them escape into the atmosphere, but it will also allow to reduce greenhouse gas (GHG) emissions and implement profitable projects to save money.
