The urban solid and special non-hazardous waste-to-energy plant of Rea Dalmine S.p.A., a Greenthesis Group’s company, represents in the Italian and European panorama within the waste incineration sector one of the reference Best Available Techniques with respect to energy recovery and reduced pollutant emissions into the environment. Thanks to its qualifying points, it guarantees stack emissions with very low values of pollutants, reduced more than 90% compared to the limits of the European regulations.
The plant is spread over an area of 45,500 m² that includes the electrical substation, which is capable of producing 100,000 MWh electricity also from renewable sources, and a green area intended to complete the harmonious insertion of the plant in the territory. It consists of two independent lines capable of disposing of up to 450 tons of waste per day, ensuring the continuous maintenance of the service to the municipalities that have to deliver daily municipal waste produced in their territory and guaranteeing a public utility service. Rea Dalmine receives waste from a catchment area equivalent to 700 thousand inhabitants and can meet the annual domestic energy needs of more than 110 thousand people.
In addition to electricity, thermal energy will also be generated from the waste-to-energy plant, which will be fed through an agreement with A2A Calore e Servizi (ACS) into the district heating circuit of the city of Bergamo, increasing the heat available in the network by 50 percent and allowing the service to be expanded by involving other areas of the city. The plant will be connected to the existing network in the vicinity of the A2A plant in Goltara (Lallio) via a feeder (round-trip) about 5 km long.
The project, in which two major companies are engaged in a multi-year partnership, consists of the cogeneration conversion of Rea Dalmine’s waste-to-energy plant and connection to the city grid. A resource present in the area and not currently exploited will thus be used to respond to a real need for heating and air conditioning of population centers.
All this will allow during the “Winter Thermal Season” the input of an amount of heat equal to 90,000,000 thermal kWh into the heating circuit of the city of Bergamo.
