biomethane

During the ANAEROBIC phase, the BIOGAS is generated thanks to the action of bacteria which, similarly to what occurs in nature, transform the organic substance into the first of the hydrocarbons, methane, and into other substances.

However, methane, if released into the atmosphere, contributes to the global greenhouse effect. If, on the other hand, it is intercepted and used as fuel, it works as an ENERGY VECTOR: solar energy, thanks to chlorophyll photosynthesis, is converted into vegetable organisms, releasing oxygen and fixing the carbon dioxide of the atmosphere. Animals eat plant foods. Food scraps and animal manure, in the absence of oxygen, generate methane. Methane, if it is intercepted and used as fuel (biomethane), releases the solar energy stored in organic waste. The residue from biomethane combustion is essentially made up of water and carbon dioxide, in the same quantity as that absorbed during photosynthesis. In this way the carbon dioxide balance is zero, and the carbon cycle starts all over again. The energy produced by combustion is therefore completely renewable.

The BIOGAS generated in the plant, which contains over 50% of methane, is captured by a pipe and subjected on site to a treatment (upgrading) which makes it in all respects equal to the methane of fossil origin that is distributed by the network national. The Biogas, transformed into BIOMETHANE by the UPGRADING process, is then introduced into the gas network. The energy that this BIOMETHANE carries is completely renewable with zero impact. Carbon dioxide, which presents food grade characteristics for industrial purposes, is also recovered and valorised.
