Technology description

The first phase of the process consists of an anaerobic biodigestion (in the absence of oxygen), which allows to associate the recovery of material (compost) with an innovative energy recovery system (biogas). The organic waste coming from the separate collections undergo, first of all, a series of volumetric reductions and mechanical selections. These operations allow the removal of any foreign fractions, such as plastic and metals. The refined mass comes transferred to intermediate tanks, where the material is diluted in water and the material is preheated. After the preparation phase, the mass is pumped into the digesters. The process involves constant handling of biomass. The extraction of the sludge takes place from the conical bottom of the digester, by gravity mixing. Digested organic waste (digestate) it is dehydrated and then sent to the neighboring composting system. The biogas obtained from fermentation it is conveyed to a gasometer and temporarily stored. The water used in the process is partly recirculated, while the remaining portion is sent to purifier. Biogas is a natural gas, rich in methane, which can be used as a replacement of common fossil fuels, for the electricity and thermal energy production. This mixture is naturally generated by the decomposition of organic waste, through anaerobic digestion processes. If not properly treated, it can constitute a problem for the environment, but thanks to a technological system devised by ACEA, biogas represents, instead, a resource. The biogas coming from the plants of the Integrated Environmental Pole and also that produced at the landfill (which is approx 3 km from the site) is stored in a gasometer. From here it is sucked, cooled and sent to the otto cycle engines.
