anaerobic digestion diagram


Anaerobic Digestion (Anaerobic meaning "in the absence of oxygen") is the process by which organic matter such as animal or food waste is broken down to produce biogas and biofertilizer. This process happens in the absence of oxygen in a sealed, oxygen-free tank called an anaerobic digester. Anaerobic Digestion is widely used as a source of renewable energy.  


The biogas naturally created in the sealed tanks is used as a fuel in a CHP (combined heat and power) unit to generate renewable energy (i.e. electricity and heat).  The biogas can be used directly as fuel, in combined heat and power gas engines or upgraded to natural gas-quality biomethane.  

How is Anaerobic digestion advantageous in terms of ENERGY

1. Anaerobic digestion is a net energy-producing process.
2. A biogas facility generates high-quality renewable fuel.
3. Surplus energy as electricity and heat is produced during anaerobic digestion of biomass.
4. Anaerobic digestion reduces reliance on energy imports.
5. Such a facility contributes to decentralized, distributed power systems.
6. Biogas is a rich source of electricity, heat, and transportation fuel.

Did you Know?  Every ton of food waste recycled by anaerobic digestion as an alternative to landfill prevents between 0.5 and 1.0 ton of CO2 from entering the atmosphere!  That's Huge!


This is just one of the benefits of Anaerobic Digestion.
