Biogas is a clean environment friendly fuel. Raw biogas contains about 55–65% methane (CH4), 30–45%

Because methane is a natural gas which has been involved in the Earth’s earliest atmosphere.

The renewable energy that the Georges produced through the bio-gas is set up to offset the farm's electricity use and/or sell the power at wholesale rates to the local utility. In the article it stated that the change to bio-gas results in less odor-causing compounds in manure in a liquid storage system and the breaking down of manure in the digester changes the organic nitrogen into ammonium which is when spread on the fields it’ll become more readily available when consumed by the plants allowing for less nutrient runoff. Also reduces weeds appearing in the fields causing less weeds growing with crops. Another great thing about the digestion process it also reduces methane, a greenhouse gas, emissions (basically global warming) which would otherwise remain in the atmosphere for 9 to 15

The data does not support the hypothesis, since the products that produced more biogas were not the vegetable peelings and the cow manure. The average difference between the vegetable peelings (approximately 0.6 cm) and the mashed bananas (approximately 2.5 cm) were 1.9 cm

Looking at the variety of gases that are now trapped inside our atmosphere one always seems to point at the largest one Carbon Dioxide (CO2). With the United States being the largest producers of beef in the world and knowing that through enteric fermentation methane (CH4) is produced, I wanted to truly understand how methane is produce at such a large scale. As humans we need to truly understand how our actions and ways of life are impacting our surrounding environments. Domesticated ruminants are responsible for the production of 86 million metric tonnes (Tg) of methane per year, alone beef cattle contribute 55.9 Tg and dairy cows 18.9 Tg per year (Hook, S.

Claim of definition: Biofuels are energy sources made from living things, or the waste that living things produce and can be produced from a wide variety of sources such as sugars, starches, oil, and animal fats.

Results from this experiment showed that methane production rates were different for each substrate used. Methane production was higher and faster in cultures using acetate as a substrate than cultures using methanol. At the same initial concentration of methanol or acetate, 20 mmol/medium of methane was produced in just three days if using acetate, while if using methanol, methane production

Cattle are known for their large production of methane. They eat a typical diet of grass and hay. Methanogens help them process these foods, which are high in cellulose. Methanogens are types of bacteria that live inside the rumen of cattle and other ruminants. The microorganisms eat the fiber and other indigestible parts of the grasses and produce methane as a byproduct, in the same general way that yeasts consume sugar and produce alcohol.

Methane is the second most important greenhouse gas. Even though there is less methane in the air than carbon dioxide, methane is much more absorbent of infrared radiation than carbon dioxide. Methane comes from many places. Large amounts of methane gas come from cattle. The plants and grass that the cattle eat are broken down by different types of microorganisms. Methane is then produced by their digestion process. These cattle belch every two minutes and release methane gas each time they do it. Since one cow emits a half pound of methane a day and there are 1.3 billion cattle in the world, more than 100 million tons of methane are released each year into the air (Bilger 50). Another type of animal that releases methane gas is a

They are responsible for the methane in the belches of ruminants, as in, the flatulence in humans, and the marsh gas of wetlands. Methanogenic archaea, are an important group of microorganisms that remove excess hydrogen and fermentation products produced by other forms of anaerobic respiration produce methane as a metabolic by-product under anaerobic conditions ecosystem. Because of this, methanogens thrive in environments in which all electron acceptors other than CO2 (such as oxygen, nitrate, trivalent iron, and sulphate) have been depleted. In spite of this, since the process of methanogenesis also produces methane, which has a global warming potential 21 times greater than that of carbon dioxide. This effect can fortunately be offset through the use of methane as a

Biofuels have been used as a source of energy for thousands of years. Wood was the first biofuel to be used as a means to create fires for cooking. Since that time we have discovered numerous ways to use them and the various forms of biofuels that are available for use. Presently our use of biofuels consists largely of additives to gasoline in the form of ethanol. Ethanol is found in almost all of our gasoline products today, in which about 10% is typically mixed as an additive. Some gas stations are now offering nearly pure ethanol fuel known as E85 which is 85% ethanol. This makes ethanol the most common biofuel used worldwide. In response to this, farmers around the world have increased biofuel plant production as a means to meet the new growing demand for it. As time goes on, more modern farming practices are expected to continue to increase the output at which farmers can grow corn and other ethanol producing plants thereby “fueling” the biofuel gas industry. With more resources available to use, ethanol will be an even cheaper additive than it is now.

Biofuel is a type of energy which can be derived from biomass, animal waste and most controversially from renewable plants. Biofuel is used as a substitute for oil and other energies. The reasons for the growing fame of biofuel is both negative and positive as it is an alternative form of energy for the government and makes their life easy, on the other hand biofuel has made people life miserable by causing a raise in food prices. Biofuel is currently present in many different forms including Biodiesel, Bioethanol and Biogas.

“Biodiesel is a fuel that is produced from seed oil such as sunflower seeds or soybeans, fats from vegetables and animals and microorganisms such as algae”. (http://www.greenchoices.cornell.edu/energy/biofuels/) Biodiesel has no petroleum, but petroleum blends with biodiesel can be made where petroleum engines can run on. There are a variety of blends that can be made with biodiesels and its efficiency depends on its blend. “B20, B5, and B100 are the most common blends used today”. (http://www.consumerenergycenter.org/transportation/afvs/biodiesel.html)

Bioreactor is a modern landfills introduced in solid waste management, thus this concept are not fully universally applied yet. The objective of this bioreactor landfills involving disposal solely of inert materials after universally applied. Therefore, it is likely that landfills will continue to receive a variety of materials with potential for environmental impact. As the leachable materials are land disposed, impenetrable barriers are provided and waste stabilization is enhanced and accelerated so as to occur within the life of these barriers (Lee & Jones- Lee, 1996). That is, the landfill must be designed and operated as a bioreactor. This bioreactor landfills is equipped with liners and leachate collection systems. It operated and controlled to rapidly accelerate the biological stabilization of the land filled waste. The crucial process in bioreactor landfills is leachate recirculation, which leachate is recycled back to the landfill, to create the environment favorable to rapid microbial decomposition of the biodegradable solid waste (Lee & Jones- Lee, 1996). Additional advantages of the bioreactor landfill include increased gas production rates over a shorter duration, improved leachate quality, and more rapid landfill settlement. Instead of that, bioreactor operations protect the environment and reduce long- time liability and associated monitoring costs (Reinhart & Townsend, 1997). The rapid treatment of the waste facilitates the operation of a bioreactor landfill

Methane is one of the important green house gases and its production in India is 105 Tg/year, out of which about 60% is produced by enteric fermentation of ruminants. About 92% of it is produced only by cattle and buffalo and 8% is generated by all other herbivorous animals like sheep, goat, yak, mithun, horse, elephants etc. The mitigation techniques of methane include plant secondary metabolites (tannins, saponins, essential oils and alkaloids containing plants), inorganic terminal electron acceptors (nitrates and sulphates), chemical composition of feed (concentrate/roughage ratio) and chemical and microbial intervention. By using these techniques individually or in combination, might lead to 30-40% methane inhibition.

Biogas production generally simple, and not as complex, as other types of clean energy. Solar power might use critical ingredients, would usually be costly. Other conventional energies might go along those same lines. Biogas production, however, is considerably unique. Along with composting, biogas production can either include everyday kitchen scraps, or heavy duty agricultural excess. Inevitably, biogas production includes sources of biomass that undergo a biochemical development. (U.S.D.E., 10 May 2016).
