VDM Energija Donji Miholjac
An innovative and efficient biogas plant Made in Italy, perfectly integrated into the production cycle, created by IES BIOGAS, able to enter into the national grid up to 1067 kW per hour and meet the needs of 3.000 families, without waste, without odor, to the benefit of the environment and the community. At the same are produced thermal energy for district heating and natural
fertilizer quality. So the cycle is perpetuated over time, with a high level of efficiency.

The biogas is one of the alternative sources more used for the production of renewable energy.
The biogas is the product of the microbial degradation of organic substances in the absence of oxygen, a process commonly
called anaerobic digestion. It is a mixture of gases, composed mainly of methane (CH4) and carbon dioxide (CO2).
Corn silage, Milking cow scurry and Cow manure, are inserted daily into the two primary digesters. Here they remain for about 100 days and then go in the storage tank covered. The process and then type a “dual-stage” and occurs at a temperature of 38-42 degrees (mesophily conditions). The technology to “double-stage” allows you to have a fermentation process secure and resilient but especially ensures retention times appropriate.
The coverage of storage in addition to ensuring a complete degradation and therefore an effective exploitation of biomass used, allows a greater reserve of biogas and allows for better desulfurization (removal of the H2S). Desulphurisation and of biological type for injection of very small amounts of oxygen. The internal structure and a network desolforatrice offer a good surface for the colonization of bacteria desolforatori. The biogas produced is conveyed to the cogenerator that produces electricity and thermal energy. The first is transferred to the public network, the heat instead is reused in part for the fermentation process, in part because of the district heating of the stables and offices. At the end of the fermentation process is obtained the digestate, a liquid material, completely odourless, high value for cultivation, with improved features with respect to the starting material.
The digestate undergoes a process of solid/liquid separation: the solid that has the consistency, the appearance and smell of a
“humus”, is distributed in the fields with a wagon manure spreaders or sold to specific users as the gardens-florists.
Biogas is an opportunity to produce energy locally and in a sustainable way, improve the impact of the herds, diversify the income of farms, giving the farmer with the possibility to gain a secure. Biogas can also be tool in order to ennoble the role of “resource” by-products of the asset farm difficult to reuse otherwise, which are converted into opportunities for further income and lever for a healthier environment.
