Thanks to the will of some farmers to support their farms during a difficult period for the agriculture, the Agribioenergia Società Cooperativa Agricola was founded in 2005.
The aim was to set up a plant for the anaerobic digestion of various organic “matrices” such as corn, sorghum, cattle slurry, and by-products of agroindustry processes, in order to obtain biogas and as a consequence electricity and renewable heat.
An important aspect of this process is precisely the “digestate”. The biomasses, during the brew cycle, which can last from 120 to 180 days, undergo some transformations, including methane extraction and the mineralization of nutrients such as nitrogen, phosphorus and potassium thus making them directly assimilated by plants and becoming a completely organic fertilizer.
In this process the matrices are fully stabilized, eliminating any unpleasant smells; the use of this “digestate” as fertilizer, has allowed a significant reduction of the use of synthetic fertilizers on our fields.
into electricity and heat without air emissions (not exceeding the emissions of a large vehicle fuelled by methane) and with no waste production.
All this happens under the direct control of the agricultural enterprise, with the main purpose of remunerating the contributing shareholder farmers.
Over the years, the cooperative has progressively refined the choice of the crops appropriate for the biomasses. In particular, the cooperative still tries to identify and select the most productive plants varieties, that require less water and technical means thus having the maximum yield.
Another objective of the cooperative is to seek and identify agricultural by-products to supply the plant, replacing progressively the cultured biomasses. As of today, more than the half of the introduced biomasses are made up by by-products.
Thanks to these elements of study and research, it has become possible, between 2012 and 2016, to reduce by 30% the hectares of dedicated crops.
The Board of Directors is still investing in research and initiatives for the development of the cooperative. These are aimed at using the thermal energy that is currently not exploited and enhanced by the plant.
