BIO TREATMENT PLANT IN CAMPOSAMPIERO / ETRA SPA
The plant of Camposampiero, active since 2005, combines a biological wastewater and a solid waste (food waste, zootechnical wastewater, sewage sludge) treatment plant for the production of energy from renewable sources. Food waste entering the plant undergoes specific pre-treatments, which depend on the waste source, and it is subsequently digested anaerobically, in order to produce biogas and digested sludge. Starting from the produced biogas, electric and thermal energy is generated through co-generators and boilers. In particular, the plant treats about 49,000 tons/year of waste, producing more than 3 million kWh/year of electric energy and more than 5 million kWh/year of thermal energy.
ANAEROBIC DIGESTION PLANT IN BASSANO / ETRA SPA
The treatment plant in Bassano, active since 2003, processes food waste and residual non-recyclable waste derived from separate collection in the Vicenza 5 basin, with a total amount of about 70.000 tons/year. In particular, food waste undergoes mechanical pre-treatment and anaerobic digestion. The biogas produced within the three digesters is used for the production of electric energy, enabling the plant to self-sustain its energy expenses and to sell the excess energy generated. The digested sludge is composted in order to allow the production of high quality compost. The non-recyclable waste treatment line consists of different physical-biological processes units, aimed at the production of RDF/SRF and biostabilized material to be used as landfill cover.
FUSINA THERMAL POWER PLANT 'ANDREA PALLADIO' / ENEL
The thermal power station Andrea Palladio, owned by ENEL, is a multi-fuel power plant with a total installed capacity of 1240MW. The production plant is composed of five sections propelled by coal, natural gas or fuel oil. The biggest two can also be powered by waste. After extensive testing approved by the Region of Veneto and the Province and City of Venice, the plant is now able to make safe use of 70,000 metric tons of RDF (equivalent to the waste generated by 300,000 people). The facility has also a sixth group, a gas turbine combined cycle which is the first industrial-size turbine powered by hydrogen in the world. The gas is recovered as a by-product from the chemical processing and propels the group for an electrical power of 12 MW gross. The exhaust gases of this group can be recovered in a special boiler, increasing the overall performance.
BRESCIA WASTE-TO-ENERGY PLANT / A2A
The waste-to-energy plant is located in the south of Brescia, near other production plants belonging to the same company and connected to the city's district heating network. The waste-to-energy plant significantly contributes to the energy demand of the city of Brescia. In fact, in addition to the production of electricity, it recovers the generated heat and conveys it, through a district heating network of over 630 km, to the individual users’ homes. The plant is composed of 3 interdependent combustion units fed by unsorted urban waste and non-hazardous special waste.
