The Modern Importance of Biogas

The Modern Importance of Biogas

The use of biogas is increasing rapidly rapidly today for a number of reasons:

Fuel costs have been rising steadily for a number of years and the taxation burden increases as well, leading to a double load ofr the user to bear.

Attempts are now being made to improve the use of renewable energy sources.

The gas produced, mainly methane, is one of the major causes of the greenhouse effect.

The production is possible in small scale sites, obviating the need to supply energy to outlying areas.

Even a very basic construction using mostly used materials will produce gas if a few simple design rules are followed.

This is not meant to be a construction guide for biodigesters or any of the other equipment needed for this purpose, it is rather a discussion of the control systems in use for the landfill schemes that are in use in many countries already.
