Finnish technology firm Valmet has secured a contract to supply a heat recovery system to Veolia’s EC4 combined heat and power plant in Łódź, Poland, as part of efforts to reduce emissions from the city’s heating network, Bioenergy Insight reported.
The new system will capture waste heat from flue gases and transfer more than 50 megawatts of energy into Łódź’s district heating network. The project is expected to cut carbon dioxide emissions by over 82,000 tonnes each year.
Veolia said the upgrade will increase renewable heat production at the EC4 plant by about one-third without increasing biomass use.
Under the contract, Valmet will install three stages of flue gas condensing equipment to improve heat capture. The company will also supply a system to treat condensate for reuse in plant operations and expand the existing Valmet DNA automation system already operating at the facility. The system is scheduled to begin operations in the third quarter of 2027.
The investment is part of Veolia’s broader GreenUp plan to decarbonise Łódź’s district heating system. The programme also includes plans for a new gas-fired unit and a heat storage facility. Together, these projects aim to end coal use in the city’s heating system by 2031.
Lari-Matti Kuvaja, a director at Valmet, said the project highlights the benefits of combining heat recovery technology with efficient heat pumps and using a single supplier for both process technology and automation.
The contract was recorded in Valmet’s order intake for the fourth quarter of 2025. Financial details were not disclosed.
