Anaerobic digestion is a natural process where microorganisms break down organic matter, such as food waste and manure, in the absence of oxygen. This process occurs in specialized environments called digesters, where the organic material is decomposed, producing biogas and digestate. Biogas primarily consists of methane and carbon dioxide, which can be used as a renewable energy source. The digestate, a nutrient-rich material left after digestion, can be used as fertilizer for crops, enhancing soil health. Anaerobic digestion is an effective way to manage waste, reduce greenhouse gas emissions, and produce sustainable energy, contributing to environmental conservation and resource recovery.
