Biogas is a renewable fuel produced by the breakdown of natural matter akin to food scraps and animal waste. It can be utilized in a variety of ways together with as vehicle fuel and for heating and electricity generation. Read on to be taught more.

What is biogas? How is biogas produced?

Biogas is an environmentally-friendly, renewable energy source.

It’s produced when organic matter, corresponding to meals or animal waste, is broken down by microorganisms in the absence of oxygen, in a process called anaerobic digestion. For this to take place, the waste materials must be enclosed in an surroundings where there isn’t a oxygen.

It will probably happen naturally or as part of an industrial process to intentionally create biogas as a fuel.

What kind of waste can be utilized to produce biogas?

A wide variety of waste materials breaks down into biogas, together with animal manure, municipal garbage/ waste, plant material, meals waste or sewage.

Which gases does biogas contain?

Biogas consists mainly of methane and carbon dioxide. It can also include small quantities of hydrogen sulphide, siloxanes and a few moisture. The relative quantities of those differ relying on the type of waste concerned in the production of the resulting biogas.

What can biogas be used for?

To fuel vehicles – if biogas is compressed it can be used as a vehicle fuel.

As a replacement for natural gas – if biogas is cleaned up and upgraded to natural gas standards, it’s then known as biomethane and can be used in a similar way to methane; this can embody for cooking and heating.

Biogas: 6 fascinating info

1. Biogas is a gas of many names

Biogas is most commonly additionally known as biomethane. It’s also sometimes called marsh gas, sewer gas, compost gas and swamp gas in the US.

Biogas is a naturally occurring and renewable supply of energy, resulting from the breakdown of organic matter. Biogas is not to be confused with ‘natural’ gas, which is a non-renewable source of power.

2. Biogas and biomass: relatedities and differences

Biomass and biogas are both biofuels; they can be burnt to produce energy. But biomass is the stable, natural material. Biomass has been used as an energy source since people first discovered fire and burnt wood, plants and animal dung to create energy.

Immediately, many power stations run by burning a biomass of compressed wood pellets – a by-product of timber and furniture-making. By replacing fossil-fuel coal, biomass enables renewable electricity to be produced.

3. Biogas isn’t a new discovery

The anaerobic process of decomposition (or fermentation) of natural matter has been happening in nature for millions of years, even before fossil fuels, and continues to happen throughout us in the natural world. At present’s industrial conversion of natural waste into energy in biogas plants is just fast-forwarding nature’s ability to recycle its helpful resources.

The first human use of biogas is thought up to now back to three,000BC in the Middle East, when the Assyrians used biogas to heat their baths.

A seventeenth century chemist, Jan Baptist van Helmont, discovered that flammable gases could come from decaying natural matter. Van Helmont can be accountable for bringing the word ‘gas’, from the Greek word chaos, into the science vocabulary.

The first massive anaerobic digestion plant dates back to 1859 in a leper colony in Bombay.

An creative Victorian engineer, John Webb from Birmingham, created the Sewage Lamp, which transformed sewage into biogas to light avenue lamps. The only remaining Webb Sewer Lamp in London is now just off The Strand in Carting Lane – or as some wags would have it, Farting Lane.

Anaerobic digestion was used as a method to treat municipal wastewater, before chemical treatments. In the growing world the anaerobic process is still recognised as an inexpensive, natural various to chemical substances and the reduction of dysentery bacteria.

And let’s not forget that in Mad Max Past Thunderdome the post-apocalyptic settlement Bartertown, run by Tina Turner’s terrifying Aunty Entity, is powered by a pig-farm biogas system with biogas used to energy the desert-chasing vehicles.

4. As we speak China leads the world in the usage of biogas

China has the most important number of biogas plants, with an estimated 50 million households utilizing biogas. These are largely in rural areas and small-scale home and village plants.
