Animal manure produces electricity


At the same time, a gas development project of global methane prevents overheating
 It is not complicated nor costly expense represents the biogas can be used as household fuel, is basically obtained from the feces of cattle or pigs, but you can also take advantage of other animals and even that of the human being.Biogas is an alternative energy option which has been running strong since 2006 at national level, but Guerrero is hardly known, and that even in Mexico Initiative, which promotes a national broadcaster, as recently awarded a project of this nature, with the idea to stop using firewood in rural areas.Excrement is bulkAccording to the Director of Inspection and Supervision of the Office of Ecological Protection of the State of Guerrero (Propeg), Salvador Mojica Morga, the project in the state is serious, and even could be used wastewater treatment plant of Pungarabato.Although no exact dates handled, the state official explained the importance of alternative energy pulse, and felt that before this year could begin to see the first steps. Once in Tierra Caliente who takes this option, he said, Armando Cabrera Villela, El Chino Cabrera, between two other people.With a basic, low cost (up to 500 billion pesos in the most extreme cases) among lighter, valves and some more tools, you get the animal excrement is mixed with water pockets, and allowed to ferment. "It's a very expensive exercise, and saves a lot of money," he explained Mojica Morga.The raw material is not complicated, because a cow produces daily about 8 pounds of excrement a horse, four, and a pig, 800 grams, released the same official, "it is time to become aware and stop devastating our forests, plus it is very cheap, and families save significantly. "He said that it will open support for projects of this nature, and insisted on working "a megaproject to Pungarabato, with its wastewater treatment plant, we need only basic equipment, as the raw material and have it abundantly."

 Technical ExplanationThe technical explanation says that biogas or "swamp gas" is produced by anaerobic fermentation (without oxygen) of organic and inorganic waste, which mixed with water and placed in a closed container called a digester impervious to temperatures between 20 and 30 degrees Celsius, break down due to anaerobic bacteria.The first experiments were made at the beginning of the century, avoiding the pollution that leads to the elimination by incineration and also motivated by the difficulties caused wars in the fuel supply.Most biodigesters were built on farms. "One of the advantages is that it would devastate lower scales," said the alternative energy researcher, Miguel Antonio Vargas Palomeque.For this purpose, is in addition to manure, food waste, urine, agricultural residues such as seeds, straw, bark of sugarcane waste as well as blood traces, meat, fish waste, agro-industrial waste: sawdust, waste snuff, bran rice, fruit and vegetable waste, and forest residues such as branches, leaves, bark.For a home BioDigest said Palomeque study, requires a plastic bottle of 18 liters, an oversized rubber ball or inflatable ball, a T-connector aquarium, aquarium tubing, a valve for aquariums (with key) , a cork that fits into the mouth of the bottle, and a bunsen burner.
The stagesFor biogas are three main steps: hydrolysis, acid phase and phase hydrogen. At the end, you get a gas and a liquid. The gas contains 55-70% methane, 30-40% Carbon Dioxide, and Hydrogen 1-3% 2, and 5% other gases.The liquid known as bio-fertilizers, containing 20% ​​protein, 14% nitrogen and 20% more potassium, than the same mixture of waste processed aerobically and pH (acidity) of 7.5. Another feature of the bio-digestion, is that 99% of the parasites (amoebas, colis, tapeworms, etc..) Die in the process.Thus, not only solves problems of sanitation, but also produces a fertilizer fuel and energy independence allows rural property. The digestive process is completed between 30 and 40 days produced the greatest amount of biogas.Since the state government headed by Angel Aguirre Rivero, is in the study of a larger project to be implemented throughout the state, and municipalities, it is important and interesting to "see what can be achieved with this option alternative energy, "Mojica Morga framed.And is that only the raw material by means of cattle, you have insured more than 8 million pounds a day, not counting what they produce pigs, horses and even humans, "we will give several blows at the same time, I think the mayors and other officials must begin to operate in the interests of the entity. "And, only excrement, that is now discarded, and that lead to drainage networks of rivers, in the case of human waste, so raw contaminated water bodies, and instead of help, harm "You have to take to that."
