What Is Biogas?

Biogas is a renewable fuel produced by the breakdown of organic matter similar to meals scraps and animal waste. It may be used in a wide range of ways together with as vehicle fuel and for heating and electricity generation. Read on to be taught more.

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

It’s produced when organic matter, comparable to food 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 material needs to be enclosed in an atmosphere where there is no such thing as a oxygen.

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


What sort of waste can be used to produce biogas?
A wide number of waste material breaks down into biogas, together with animal manure, municipal rubbish/ waste, plant material, meals waste or sewage.


Which gases does biogas include?
Biogas consists mainly of methane and carbon dioxide. It could possibly additionally embody small quantities of hydrogen sulphide, siloxanes and a few moisture. The relative quantities of these differ depending on the type of waste involved in the production of the resulting biogas.


What can biogas be used for?
To fuel vehicles – if biogas is compressed it can be utilized 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 embody for cooking and heating.


Biogas: 6 fascinating facts

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: similarities and differences
Biomass and biogas are both biofuels; they are often burnt to produce energy. However biomass is the stable, organic material. Biomass has been used as an energy source since people first discovered fire and burnt wood, plants and animal dung to create energy.

Today, many energy 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 shouldn't be a new discovery
The anaerobic process of decomposition (or fermentation) of organic matter has been occurring in nature for millions of years, even before fossil fuels, and continues to happen all around us within the natural world. At the moment’s industrial conversion of organic waste into energy in biogas plants is solely fast-forwarding nature’s ability to recycle its helpful resources.

The first human use of biogas is believed so far back to three,000BC within the Center 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 organic matter. Van Helmont can be answerable 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 converted sewage into biogas to light road 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 means to deal with municipal wastewater, before chemical treatments. In the creating world the anaerobic process is still recognised as an inexpensive, natural different to chemical substances and the reduction of dysentery bacteria.

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


4. At this time China leads the world in the use of biogas
China has the largest number of biogas plants, with an estimated 50 million households utilizing biogas. These are principally in rural areas and small-scale house and village plants.
