The energy source of farms.


Biogas: new energy
from nature.

 

Biogas is one of the most widely used alternative sources for the production of renewable energy. It is the result of the decomposition in the absence of oxygen (a process called anaerobic digestion) of various organic substances, by a large amount of bacteria. 
 
The energy contained in chemical bonds is then released and stored mainly in methane (CH4) which, along with carbon dioxide (CO2) is the main constituent of biogas. The other substances, present in lower percentages, are carbon monoxide, nitrogen, hydrogen, hydrogen sulphide.
 
Biogas has a high calorific value and can be converted into electricity and heat. The fermentation remains is called digestate, which is a completely odourless liquid material with high agronomic value, with improved features compared to the starting material. 
 
Biogas is identified by the EU among the non-fossil renewable energy sources that can provide not only self-sufficient energy but also the gradual reduction of the current state of air pollution and thus the greenhouse effect.
