Biogas
Biogas
Biogas (/ˈbaɪoʊˌɡæs/) is a type of biofuel that is naturally produced from the decomposition of organic waste. The term "biogas" comes from the Greek word "bios" meaning life and the English word "gas".
Etymology
The term "biogas" is derived from the Greek word "bios" meaning life and the English word "gas". It was first used in the late 19th century to describe a gas produced by the biological breakdown of organic matter in the absence of oxygen.
Production
Biogas production is a natural process that occurs when organic matter, such as food or animal waste, decomposes in an environment without oxygen (a process known as anaerobic digestion). This process produces a mixture of gases, primarily methane and carbon dioxide, which can be used as a source of renewable energy.
Uses
Biogas can be used in a variety of ways, including for heating, electricity generation, and as a fuel for vehicles. It can also be cleaned and upgraded to natural gas standards, when it becomes bio-methane.
