Anaerobic digestion is a natural process where microorganisms break down organic materials, such as food waste and manure, in the absence of oxygen. This process occurs in specially designed containers called digesters, where the organic matter is transformed into biogas, a renewable energy source primarily made up of methane. The remaining material, known as digestate, can be used as a nutrient-rich fertilizer for soil. This method not only helps reduce waste but also contributes to sustainable energy production. By harnessing the power of anaerobic digestion, we can decrease greenhouse gas emissions and promote a circular economy, benefiting both the environment and agriculture.
