New thermal waste processing facility for the Szczecin metropolitan area

Residents of Szczecin and the surrounding area are to reap the benefits of world-class environmental technologies thanks to a new processing plant which takes in waste and uses it to produce heat for the region’s water and electricity grids.

Additional tools


This investment is for the construction of a thermal waste processing facility with energy recovery capabilities, which is capable of dealing with 150 000 tonnes/year of waste. The site will also house a new slag valorisation plant, which has a capacity of 37 800 tonnes/year. In addition, the project provides equipment for the solidification and chemical stabilisation of dust and solid residues.

State-of-the-art technologies

The main features of the new system include:

  • A furnace with an inclined or horizontal grate, the design of which has been tested at municipal thermal waste facilities across the world, and which is able to incinerate waste of differing calorific value;
  • An integrated furnace with recovery boiler;
  • An efficient system for the recovery of energy contained in waste through interaction with a steam condensing extraction turbine that can deal with temperatures up to 400oC and pressures of 40 bar. This allows for a combined electricity and heat production that can provide the district with hot water and the public grid with electricity;
  • Exhaust purification, with an effective selective catalytic system to reduce nitrogen oxides, which meets the most stringent emission requirements;
  • A wet electrostatic-assisted desulfurisation system combined with dust blasting which reduces acidic impurities, dust, heavy metals, dioxins and furans.

By using a steam condensing extraction turbine and heat exchanger, the new facility heats mains water from the district’s heating system. The thermal power which is transmitted in the exchanger and returned to the district heating system registers at 28.8 MWth (megawatts of thermal output), which gives 777 600 GJ (gigajoules) of heat assuming the power plant runs for 313 days. However, the plant will reduce heat production to 8.2 MWth during the warmer months.

Increasing demand for the energy produced by this new facility is expected to generate regular sales into the future.

Total investment and EU funding

Total investment for the project “Construction of a Thermal Waste Processing Facility for the Szczecin Metropolitan Area” is EUR 176 801 833, of which the EU’s Cohesion Fund is contributing EUR 63 372 931 from the Operational Programme “Infrastructure and the Environment” for the 2007 to 2013 programming period under the priority axis ‘Waste management and the protection of the earth’.
