Anaerobic digestion can be an excellent tool to convert waste into renewable energy; so why isn’t everyone using it?

For those of you less familiar with the terminology anaerobic digestion, let me first introduce this process. Anaerobic digestion (AD) is one option to treat concentrated organic waste streams, such as sewage sludge, manure, and food processing waste. The process is driven by anaerobic microorganisms, which means that microbes decompose the waste material while growing and reproducing in an environment void of oxygen. These organisms will die if oxygen is present. Anaerobic digestion is like composting, but instead of maintaining a good aerobic (with oxygen) compost pile, the organic waste is put in a completely sealed container void of oxygen (for more detail see the new WSU Fact Sheet: Mitchell et al., 2015).
