Collection of Organic Materials

Biogas comes from decomposing organic materials like manure, crop waste, food scraps, landfills, and wastewater treatment sludge.

Anaerobic Digestion (AD)

The collected materials are placed in a sealed, oxygen-free container called a digester. Microorganisms break down the organic matter, generating biogas. This process is called anaerobic digestion.

Biogas Collection and Storage

The generated biogas rises and is captured in a gas holder. The biogas is then stored or directly used for energy production, such as heating, electricity generation, or upgrading to renewable natural gas (RNG).

Digestate

After digestion, the leftover solid material, called digestate, is rich in nutrients which can be returned to the soil as a fertilizer or soil amendment for agriculture.

Energy Production

Biogas is used for renewable heat, electricity, and pipeline quality gas for transportation, heating, and industrial applications.
