Biogas production
|
The biological processes that include biodegradation of rubbish in anaerobic conditions are a complex series of reactions that depend on factors such as the composition of the waste material, its humidity, temperature, compacting level, acidity, etc. Its main elements are methane (CH2) and carbon dioxide (CO2) with concentrations of approximately 55% and 40% respectively. The minority elements are nitrogen (N2), oxygen (O2) and traces of other volatile organic compounds. An important aspect is that methane is one of the main greenhouse gases, with a power to absorb energy and, therefore, to heat up the atmosphere that is at least twenty times greater than that of CO2.
