Valmet will supply a flue gas condensing process to Vantaa Energy’s new high-temperature incineration plant in Vantaa, Finland. The plant is designed to process household and industry waste that is classified as hazardous and not suitable for recycling.
The order is included in Valmet’s orders received of the fourth quarter 2022. Its value will not be disclosed, but such an order is typically worth over EUR 15 million. The project will start in 2022 and the plant is scheduled for completion in 2025.
The flue gas condensing equipment recovers heat from the incineration process. The waste heat produced will be utilized in the heating of properties in Vantaa. The waste heat obtained from the plant will reduce the need for using natural gas and fossil fuels and supports the transition to clean energy production.
“The high-temperature incineration plant treating non-recyclable hazardous waste continues Vantaa Energy’s investment programme to phase out the use of fossil fuels in the company’s energy production as soon as possible and to continue towards carbon-negative energy production in 2030. Energy utilization of waste and carbon capture and processing into new products play a key role in our strategy. For Vantaa Energy the high safety level of the technology and design solutions used, implementation of the investment projects according to stringent targets and the high degree of availability of the plants are extremely important. We are delighted to have Valmet as our partner in the high temperature incineration plant project,” says Vantaa Energy’s CEO Jukka Toivonen.
“The project is an excellent example of Valmet’s ambition to provide sustainable emission reduction solutions to our customers, and we are happy to share the journey toward a carbon negative future with Vantaa Energy,” says Lari-Matti Kuvaja, Manager, Sales & Technology, Environmental Systems, Pulp and Energy, Valmet.
