Biogas and biofuelsThe biogas is a very important energy source for its environmentally sustainable contribution to economic, agricultural and rural development.
BIOGASThe biogas is a gaseous biofuel obtained by fermentation of materials and organic residues of animal or vegetable origin, in an oxygen free environment. This process is technically called anaerobic digestion.
The entire process takes place in a temperature controlled environment, thanks to active microorganisms that convert the raw material into biogas consisting for 50-70% of methane and for the remaining part by CO2 and other components. The resulting biogas can be used to produce electrical and thermal energy, even in a combined way thanks to cogeneration plants.
The most interesting aspect is the possibility to transform into a resource the residual organic materials otherwise destined for disposal. In fact, the livestock wastes ca be transformed into raw material, available for the production of renewable and clean energy.
In an easy way, the by-products of livestock and by-products of agro-industrial activities in different combination with dedicated crops may turn into electricity and heat, which the company may decide to use itself, choosing the "autonomy energy model", or sell it all or in part to the energy provider.
Moreover, the digestate - another product of anaerobic digestion - is a stable odorless material used as excellent organic fertilizer rich in nutrients, depending on materials introduced in the digester. Incorporate it into the soil in a rational way reduces NH3 ammonia emissions and replaces the nitrogen synthesis by reducing its consumption.
A WELL MADE BIOGAS
Biogas from zootechnical, agricultural and agro-industrial origin has become a significant reality in Italy, and still it offers significant growth prospects based on the development of the potential and the reduction of critical factors.
Integrating the biogas plant at the farm is the key factor for the creation of the "BIOGASDONERIGHT®" model and it's the element from which may start a real change for a productive and sustainable agriculture.
In fact, if well integrated with the farm, the biogas plant allows the enhancement of its vegetable and animal waste, returning the digestate, that is an excellent bio-fertilizer to return organic substance in the soil.
You can then move from an intensive agriculture model - in which the productions are intended directly for the processing industry - towards an agriculture model that can close the production cycle with many advantages:
- to enhance your waste;
- to maintain fertility;
- to produce more crops, by structuring the agricultural rotations and the ground covering and applying innovative techniques;
- to reduce emissions and consumption of chemical fertilizer using the digestate.
