Turning organic waste into valuable electricity

Waste decomposition in
the fermentation tank

A pumpable mixture of water and organic components are the basis of life for bacteria. They decompose the substrate, break it down and generate biogas. The digestate is kept in constant motion to prevent sedimentation on the bottom of the tank. The bacteria live in anaerobic conditions, i.e. without oxygen. This is why one speaks of anaerobic digestion. The result is biogas that is collected under the roof of the reactor and then pumped to a gas engine. The engine burns the biogas, a connected generator generates electricity.
