Each cubic meter (m 3) of biogas contains the equivalent of 6 kWh of calorific energy. However, when we convert biogas to electricity, in a biogas powered electric generator, we get about 2 kWh of useable electricity, the rest turns into heat which can also be used for heating applications. 2 kWh is enough energy to power a 100 W light bulb for 20 hours or a 2000W hair dryer for 1 hour.
How much biogas can I get out of my waste? The amount of biogas you can extract from your organic waste depends on the waste itself and the design of the digester system. Some digesters can yield 20 m 3 of biogas per tonne of waste while others can yield as much as 800 m 3 per tonne.
