Bio gas is a clean unpolluted and cheap source of energy in rural areas. It consists of 55-70% methane which is inflammable. Bio gas is produced from cattle dung in a bio gas plant commonly known as gobar gas plant through a process called digestion.
Who is the father of biogas?
Fortunately for the old man, his plea was answered by Jashbhai J. Patel, then technical advisor to the KVIC. “That man eventually helped us install 450 plants in the area,” recalls Patel, whose pioneering work earned him international recognition as the undisputed “father of biogas technology”.
Why is it called gobar gas?
Biogas is produced by the decomposition of organic wastes under anaerobic condition. The primary source of biogas production is cattle dung. Hence it is called gobar gas.
Which gas is in biogas?
Biogas is an energy-rich gas produced by anaerobic decomposition or thermochemical conversion of biomass. Biogas is composed mostly of methane (CH4), the same compound in natural gas, and carbon dioxide (CO2).
What is difference between gobar gas and biogas?
Gobar gas is Biogas specifically produced from anaerobic digestion of cow dung. Biogas is the gas produced as a result of anaerobic decomposition of organic matter like food waste, excreta, silage etc.
Who invented biogas in India?
Over the next twenty years, Jashbhai Patel designed and made several small-scale biogas digesters, envisaging farm labourers as the user.
Can we make biogas at home?
Introduction: Biogas at Home- Cheap and Easy
20-30 mins on a bunsen burner. you can add anything from your kitchen waste ( Exept Onion peels and eggshells). In 12 hours the Gas is ready for use. It is very easy and cost effective to build (only 2-3 dollars) and gives many useful products.
How much biogas can be produced from 1kg cow dung?
Biogas from cow manure with 1 kg produced as much as 40 liters of biogas,while chicken dung with the same amount produced 70 liters. Biogas has a high energy content which is not less than the energy content of the fuel fossil . The calorific value of 1 m3 biogas is equivalent to 0.6 – 0.8 liters of kerosene.
Is biogas harmful to humans?
Overall, biogas risks include explosion, asphyxiation, disease, and hydrogen sulfide poisoning. Image: US Municipal Supply Company. Extreme caution is necessary when working with biogas.
How Bio gas is formed?
Biogas is produced when bacteria digest organic matter (biomass) in the absence of oxygen. This process is called anaerobic digestion. It occurs naturally anywhere from the within the digestive system to the depth of effluent ponds and can be reproduced artificially in engineered containers called digesters.
How can we purify biogas at home?
The common technologies which using biogas purification/CO2 Capture in industry are Amine absorbtion coloumn and pressure swing adsorbtion. However for household scale, you can use water absorbtion on bubble or coloumn as simple way to purify.
How long has biogas been used?
Anecdotal evidence indicates that biogas was used for heating bath water in Assyria during the l0th century BC and in Persia during the 16th century. Jan Baptita Van Helmont first determined in 17th century that flammable gases could evolve from decaying organic matter.
What are the disadvantages of biogas?

When was biogas first discovered?
The first human use of biogas is thought to date back to 3,000BC in 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 organic matter.
Is biogas safe for cooking?
Biogas is a mixture of methane, carbon dioxide and other trace gasses. In principal, biogas can be used like other fuel gas. When produced in household-level biogas reactors, it is most suitable for cooking or lightening .
How is biogas converted to food waste?
You can make a free cooking gas by digesting wet organic waste in a sealed chamber. Summary: Place wet organic waste, such as food waste, in a sealed chamber with no air inside. As it digests, the waste will release a gas which can be captured and used for cooking.
Where is biogas found?
It occurs naturally in compost heaps, as swamp gas, and as a result of enteric fermentation in cattle and other ruminants. Biogas can also be produced in anaerobic digesters from plant or animal waste or collected from landfills. It is burned to generate heat or used in combustion engines to produce electricity.
How is biogas produced in India?
Animal manure and agricultural wastes are primarily used as feedstocks in household biogas digesters, producing biogas and bio-slurry that can be used as organic fertilizers. Mostly small-scale plants are managed by individual households to generate energy for self-consumption.
Is biogas a fuel?
Biogas is a renewable fuel produced by the breakdown of organic matter such as food scraps and animal waste. It can be used in a variety of ways including as vehicle fuel and for heating and electricity generation. Read on to learn more.
Is Biogas better than LPG?
While Biogas disperses into the air quickly as it is lighter than air and is much safer in homes than CNG or LPG. BioGas is far far far safer than LPG. Biogas is a fuel that can be a complete replacement for Petrol and CNG. It can be used in various methods to benefit mankind.
Is Gobar Gas a biofuel?
Biogas is a type of biofuel that is naturally produced from the decomposition of organic waste.
How is Biogas 10 produced?
Biogas is produced by the anaerobic degradation of animal wastes like cow-dung (or plant wastes) in the presence of water. This degradation is carried out by anaerobic micro-organisms called anaerobic bacteria in the presence of water but in the absence of oxygen.
