What is Anaerobic Digestion?
Anaerobic digestion is a set of biological processes in which bacteria degrade biodegradable materials in the absence of oxygen. This breakdown produces biogas, which is made up of mostly methane (around 50% to 70%), carbon dioxide (about 30% to 50%), and small amounts of other gases like hydrogen sulfide, ammonia, and water vapor. In simple terms, it is the process by which food or other organic matter degrades in an oxygen-free environment. Digestion is the process by which organic matter breaks down.
Many countries, including India, have experienced the commercial benefits of this approach, which provides a better alternative to conventional energy sources because it is renewable and creates few or no byproducts. Its primary applications include fermentation technology and waste management. Microorganism genera that play an important part in anaerobic digestion are: Methanogens, Acetogens, Hydrolytic Bacteria, Acidogenic Bacteria, and Syntrophic Bacteria.
Anaerobic Digestion
Anaerobic Digestion takes place in the absence of oxygen by the microorganisms. It is a natural recycling process. These microbes feed on biodegradable materials such as food waste or manure, breaking them into simpler molecules. This breakdown produces gases such as methane, which can be used as a fuel source. In this article, we will learn about anaerobic digestion, its process, wastewater treatment, digesters, etc.
