Anaerobic Digestion

Term from Waste Management industry explained for recruiters

Anaerobic Digestion is a natural process that breaks down organic waste (like food scraps, animal manure, or plant materials) without using oxygen to create renewable energy and useful fertilizer. It's like composting but in a controlled environment. Companies use this process to handle waste and create biogas (a type of natural gas) that can be used for electricity or fuel. This technology is becoming more popular as businesses focus on sustainability and reducing waste. When you see this term in resumes, it usually means the person has experience with waste treatment facilities, renewable energy production, or environmental management.
