Métodos sencillos en obtención de biogás rural y su conversión en electricidad

Currently there are several ways for get rural biogas, from the use of organic waste and small plants for use by farm families to medium and large systems. The latter are used to generate electricity from breeding farms or larger volumes of agricultural waste. This paper describes the simplest methods in current use, its applications and restrictions. The information was sought in European, American sources including the United States. The spread of these techniques allow partial renewal conventional energy sources. These come from hydrocarbons, are expensive, polluting and producing a greenhouse effect in the atmosphere. From medium and large productions “carbon bonds” can be obtained, in accounting for the gas consumed. As results delivered approximate investment costs, depending on the generation of gas produced.
