In the middle of the revolution of the alternative energies as solution to the problems related to the oil, the biodigestores are between the ways of producing cheap energy more important.
The organic matter decomposition in oxygen absence (Fermentation anaeróbica) generates a gas miscellany, between them, an important quantity of gas methane. This gas is highly combustible and it is used in many countries, (for the most part China, Brazil, India and at present in many developed country) to obtain caloric energy in alternative and economic form.
This gas miscellany, obtained by means of the process earlier descripto it is called a Biogas and the system in which the controlled fermentation takes place is named biodigestor.
Although the names make to seem that it is a question of something complicated, it it is not. They exist biodigestores very advanced and of big size and very small and simple others of the size of a 200 liters tank or less, everything depends on the gas quantity that wants to be obtained and the destination that will be given him.
For example a 2 cubic meters biodigestor can supply from gas to a housing, and satisfy his needs for kitchen and heating, allowing him to save a big money quantity by way of energy.
A biodigestor of approximately 70 m3 or 100 m3 might generate sufficient gas to make a generating group work and generate cheap electric power for a small factory.
Any person with technical secondary studies (electricity, mechanics, chemistry) or engineers of these areas he can acquire easily the necessary knowledge to make biodigestores of different sizes and to commercialize them.
The smallest biodigestores can be made from plastic tanks, fiberglass or any material resistant to the corrosion. Those of major size are constructed generally of concrete in the same place where they will work, although at present they are made also portable.
One of the advantages of the generation of biogas is that the residues of the process of biodigestion are an excellent liquid fertilizer for the field. Or that a biodigestor generates two unvaluable resources at present, gas methane for different applications (kitchen, heating of ambiences, water warming, functioning of engines to gas for generation of electric power, etc.) and liquid biofertilizer for field fertilization.
If you want to obtain more information related to the topic realize searches in Internet across Google with the following key words Biogas, biodigestores, biodigestor, biomass, manufacture of biodigestores, manufacture of a biodigestor, construction of a biodigestor, construction of biodigestores, biofertilizer
