Biogas

Biogas, swamp gas or marsh gas, consists of 50% to 80% methane and a small amount of carbon dioxide that is produced through fermentation of organic matter. Grazing cattle ingest large amounts of plant food that produces thousands of bacteria in their digestive systems. The animal waste can be placed in an airless tank where biogas will accumulate and then be used in lieu of natural gas produced from fossil fuel.

In addition, harmful bacteria that is present in waste water and decaying organic matter from the bottom of lakes and bogs can be removed by anaerobic digestion, a breaking down of sewage and organic waste under airless conditions. The biogas that is produced is an excellent source for renewable energy since it disposes of these waste materials and produces a form of natural gas that can be used for electricity, heating, and vehicle fuel.

Biogas is a renewable energy source that was recognized in the years before electricity was discovered. It was taken from underground sewer lines in London and used to light their street, or gas, lights. Biogas, collected from landfills and pig barns, is used today in many parts of the world, for heating, lighting, and cooking.

Biogas is renewable each year, depending upon the supply of grass and other plant life that is grown, in comparison to fossil fuel, such as coal and oil, which takes millions of years to form. Biogas, a reliable, renewable energy source, is an inexpensive, practical solution to the greenhouse effect of global warming.
