What Is Biogas?

Biogas is a renewable fuel produced by the breakdown of organic matter resembling food scraps and animal waste. It can be used in a wide range of ways including as vehicle fuel and for heating and electricity generation. Read on to study 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 environment the place there is no such thing as a oxygen.

It may 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, together with animal manure, municipal garbage/ waste, plant material, meals waste or sewage.


Which gases does biogas contain?
Biogas consists primarily of methane and carbon dioxide. It could additionally include small quantities of hydrogen sulphide, siloxanes and some moisture. The relative quantities of those 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 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 utilized in a similar way to methane; this can include for cooking and heating.


Biogas: 6 fascinating info

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


2. Biogas and biomass: comparableities and variations
Biomass and biogas are both biofuels; they are often burnt to produce energy. However biomass is the solid, 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.

At this time, 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 natural matter has been occurring in nature for millions of years, even earlier than fossil fuels, and continues to happen all around us within the natural world. In the present day’s industrial conversion of organic waste into energy in biogas plants is simply fast-forwarding nature’s ability to recycle its useful 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 17th century chemist, Jan Baptist van Helmont, discovered that flammable gases might 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 primary large 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 street 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, earlier than chemical treatments. Within the growing world the anaerobic process is still recognised as a reasonable, natural various to chemicals and the reduction of dysentery bacteria.

And let’s not forget that in Mad Max Past 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 energy the desert-chasing vehicles.


4. As we speak China leads the world in the usage of biogas
China has the biggest number of biogas plants, with an estimated 50 million households using biogas. These are principally in rural areas and small-scale residence and village plants.
