What is an Anaerobic Digester?
An anaerobic digester is a system that breaks down organic materials, such as food waste, manure, or sewage sludge, in the absence of oxygen to produce biogas (mainly methane and carbon dioxide) and a nutrient-rich byproduct called digestate.

Anaerobic digestion is a natural biological process used in waste management and renewable energy production. The biogas generated can be used to produce electricity, heat, or renewable natural gas, while the digestate can be applied as fertilizer. This process differs from composting, which occurs in the presence of oxygen and primarily produces soil amendments rather than energy. Anaerobic digesters are common at wastewater treatment plants, farms, and industrial food facilities, contributing to circular economy and greenhouse gas reduction goals.
