Biogas is a renewable energy source produced through the anaerobic digestion of organic matter such as agricultural waste, animal manure, food waste, and sewage sludge. This process breaks down organic material in the absence of oxygen, producing a methane-rich gas that can be used as a fuel for heating, electricity generation, and transportation.
Four types of waste commonly used to produce biogas include:
1. Agricultural waste: Crop residues, animal manure, and agricultural byproducts such as straw and husks.
2. Food waste: Spoiled or leftover food from households, restaurants, and food processing facilities.
3. Sewage sludge: Solid waste generated during the treatment of wastewater.
4. Landfill gas: Methane produced by the decomposition of organic waste in landfills.
