Biogas is a renewable fuel produced by the breakdown of organic matter comparable to food scraps and animal waste. It may be utilized in a variety of ways including as vehicle fuel and for heating and electricity generation. Read on to study more.

What's biogas? How is biogas produced?
Biogas is an environmentally-friendly, renewable energy source.

It’s produced when natural matter, resembling meals or animal waste, is broken down by microorganisms within the absence of oxygen, in a process called anaerobic digestion. For this to take place, the waste materials needs to be enclosed in an environment the place there isn't any oxygen.

It can 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 number of waste material breaks down into biogas, including animal manure, municipal garbage/ waste, plant material, meals waste or sewage.

Which gases does biogas include?
Biogas consists primarily of methane and carbon dioxide. It might probably additionally include small amounts of hydrogen sulphide, siloxanes and a few moisture. The relative quantities of these range relying on the type of waste concerned within the production of the ensuing 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 the same way to methane; this can include for cooking and heating.

Biogas: 6 fascinating information

1. Biogas is a gas of many names
Biogas is most commonly also known as biomethane. It’s additionally typically called marsh gas, sewer gas, compost gas and swamp gas within the US.

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

2. Biogas and biomass: similarities and variations
Biomass and biogas are each biofuels; they can be burnt to produce energy. However biomass is the strong, natural material. Biomass has been used as an energy supply since humans first discovered fire and burnt wood, plants and animal dung to create energy.

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

3. Biogas is not a new discovery
The anaerobic process of decomposition (or fermentation) of organic matter has been happening in nature for millions of years, even earlier than fossil fuels, and continues to occur throughout us in the natural world. Today’s industrial conversion of organic waste into energy in biogas plants is solely fast-forwarding nature’s ability to recycle its useful resources.

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

A 17th century chemist, Jan Baptist van Helmont, discovered that flammable gases could come from decaying natural matter. Van Helmont is also liable for bringing the word ‘gas’, from the Greek word chaos, into the science vocabulary.

The primary giant anaerobic digestion plant dates back to 1859 in a leper colony in Bombay.

An ingenious 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 developing world the anaerobic process is still recognised as a cheap, natural various to chemicals and the reduction of dysentery bacteria.

And let’s not overlook that in Mad Max Past Thunderdome the put up-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. In the present day China leads the world in using biogas
China has the most important number of biogas plants, with an estimated 50 million households using biogas. These are principally in rural areas and small-scale home and village plants.
