A natural gift
Biogas is one of the most widely used alternative energy sources for the production of renewable energy.
It is a totally natural gaseous mixture, consisting of:
- Methane (CH4) – 50/60%
- Carbon Dioxide (CO2 ) –35/40%
- Other gases – 1%
- Nitrogen (N2),
- Hydrogen sulphide (H2S)
- Hydrogen (H2)
- Water vapour (H2O)
The process of anaerobic digestion is the main activity for the production of biogas.
Biogas is a renewable energy source, which is generated through a biochemical process using anaerobic bacteria (bacteria which live without oxygen).
The process can be conducted in Mesophilic (35 °C) or in Thermophilic (55 °C) temperature conditions; the thermophilic process provides higher yields in biogas and completely destroys pathogenic micro-organisms (salmonella and coliforms).
The advantages of biogas
Energy and Heat
Thanks to the biogas energy is produced and / or heat, so there is no need for large power plants and reactors.
