What’s biogas?

Biogas is a renewable fuel produced by the breakdown of organic matter such as 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 learn more.

What is biogas? How is biogas produced?

Biogas is an environmentally-pleasant, renewable energy source.

It’s produced when natural matter, equivalent to food 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 material needs to be enclosed in an setting the place there is no such thing as a oxygen.

It may occur 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 material breaks down into biogas, including animal manure, municipal rubbish/ waste, plant materials, food waste or sewage.

Which gases does biogas include?

Biogas consists primarily of methane and carbon dioxide. It might probably also include small quantities of hydrogen sulphide, siloxanes and some moisture. The relative quantities of these differ 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 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 information

1. Biogas is a gas of many names

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

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

2. Biogas and biomass: relatedities and variations

Biomass and biogas are both biofuels; they can be burnt to produce energy. However 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.

Right now, many energy 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 shouldn’t be a new discovery

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

The first human use of biogas is thought so far back to 3,000BC within 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 organic matter. Van Helmont can be responsible for bringing the word ‘gas’, from the Greek word chaos, into the science vocabulary.

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

An inventive Victorian engineer, John Webb from Birmingham, created the Sewage Lamp, which transformed 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 method to deal with municipal wastewater, before chemical treatments. In the growing world the anaerobic process is still recognised as an affordable, natural different to chemicals and the reduction of dysentery bacteria.

And let’s not forget 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 usage of biogas

China has the biggest number of biogas plants, with an estimated 50 million households utilizing biogas. These are mostly in rural areas and small-scale house and village plants.
