how does a biogas generator work

Biogas is a part of the natural cycle. Before you can start making biogas, however, you need to make a digester. In order to run the system, the usage of household waste can be economical because it is available in huge amounts in some areas. The generator creates electricity which flows into the grid to power residential, commercial, government, and small industry customers. This biogas has the energy value of 876,000,000 Btu (924,000 MJ). So, with that in mind, let's take a look at how biogas digesters work, followed by steps you need to follow when making your own biogas at home.
