We produce renewable electrical and thermal energies, that means, no mineral resources such as oil or coal – that have been in our subsoil for millions of years and destined to finish- are used. This energy source, the biogas one, can be replicated from year to year, precisely because it uses the sun energy and the photosynthesis process for capturing carbon (CO2) inside the plants and for releasing oxygen in the environment. Also, through the anaerobic fermentation, this carbon changes its form and becomes partly methane (CH4) and partly remains “digested” in the substrate as an organic substance.
Over the years, thanks to the change of the regulatory framework, it has become possible to use by-products and agro-industrial wastes in our biogas plants, allowing for an important reduction of dedicated cultures in favour of matrices which otherwise would have gone to landfill or treated for disposal with serious pollution/ health- problems, not to speak of the financial costs. Besides, it should not be forgotten that the large amount of urban wet waste produced by our communities, one day, in the near future, could be re- used in the productive cycle of biogas.
The production of electrical energy, which used to be centralized in large power plants far away from the end user, becomes a local micro-production, distributed on the territory and nearer to the end user. In this way, huge energy losses, caused by the transport, are avoided and short local supply-chains are created for the procurement of raw materials and waste for the production.
Possibility to store the energy, when it is not needed, in the form of liquefied and compressed gas
Drastic reduction of synthetic chemical fertilizers when fertilizing the fields, because the “digestate”, namely all the “digested” biomasses, is a good organic fertilizer, kept stable by the anaerobic digestion which, besides reducing bad smells, transforms nutrients such as nitrogen phosphorus and potassium in a form that can be directly assimilated by plants, which also contains bacteria and micro-nutrients to revitalize soils that have lacked organic substances for many years.
Carbon capturing. The carbon that through the photosynthesis process has been removed from the atmosphere and bound in the plants, becomes biogas and then returns to the environment. The part of carbon that remains in the “digestate” and that is buried in the fields, is captured under form of organic substance.
Thermal energy. This is a by-product of the biogas cogeneration, it represents about 40% of the produced energy; if you make full use of it, it can lead the energetic efficiency of these co-generators to exceed the 80%, making them being among the most efficient machines for energy production.
Conversion into biomethane, that is the opportunity to distribute directly the methane obtained from the anaerobic fermentation and use it where and when it is needed. It could be used as fuel in vehicles powered by natural gas or in household boilers for heating and sanitary water or be transformed into electrical energy within gas power plants.
“Nothing is created and nothing is destroyed but everything is transformed.” In this case it is the carbon that continuously is transformed and creates a fundamental closed circuit for the economy of the future and of the environment. The plants, through the photosynthesis process, store the carbon within themselves. In particular, the plants intended for biomasses, during the physical and chemical anaerobic process within the biogas plant, produce methane, which is used to generate electricity and heat. Then, the gas combustion causes an emission of carbon into the atmosphere. Lastly, through the anaerobic process, an organic fertilizer substance is produced that is employed to fertilize other crops intended to biomasses. The carbon returns inside the plants and the cycle begins again. This is circular economy!
Agribioenergia is an agricultural cooperative company, it has been founded in 2005 and currently consists of 23 members. The cooperative deals with the transformation of dedicated herbaceous crops into electricity through biogas plant and anaerobic fermentation. This process allows us to have a considerable amount of thermal energy in form of hot water. Therefore, the idea of developing a further business branch dedicated to the production of medicinal herbs. These plants are dried at low temperature by means of hot water at 70 degrees which is the result of the biogas plant, recovering between 70 and 80% of the heat energy and with the aim of using it all.
The mission of the company, set since its establishment, has found confirmation in the “Best Practices Bioenergy Italy 2016 prize” recently received by Cremona Fiere. This prize recognizes our effort in trying to increase the company’s use of agro-industrial byproducts in a very short chain, with supply within 2 km, and to reduce as a consequence the use of dedicated feedstocks.
The company management commits to prevent pollution, to ensure the preservation and protection of the environment and to pursue the continuous improvement of environmental performance as part of its business.
According to these commitments, Agribioenergia aims at achieving the following objectives:
Agribioenergia si impegna a fornire le risorse necessarie affinché gli obiettivi della politica ambientale vengano integralmente raggiunti. La presente politica ambientale viene diffusa a tutti i livelli aziendali ed è compito di tutti collaborare attivamente al miglioramento della gestione ambientale.
