Local energy and circular economy
The Korvenmäki Waste-to-Energy plant converts unrecyclable municipal waste into district heating and electricity. The plant accounts for almost 90% of the district heating distributed in Salo, as well as supplying electricity to the national grid.
A waste-to-energy plant that operates safely, cost-effectively and in compliance with environmental permits supports the development of a regional circular economy. It is a link in the development of the circular economy in South-West Finland and a step in the fight against climate change.
Lounavoima Oy is a partner in circular economy and energy solutions, actively promoting systems that support recycling of materials and emissions reductions. Lounavoima is involved in carrying out innovative development projects that further the circular economy and foster positive climate impacts.
At the waste-to-energy plant site, Lounavoima's geothermal deep geothermal storage facility stores excess heat generated during the summer for use during periods of high heat demand in winter. The Korvenmäki waste treatment centre next door to the WtE plant has investigated the refinement of landfill gas into vehicle fuel. The objective is also to apply the same technology to make use of the carbon dioxide produced by the WtE plant.
Waste-to-Energy (WtE) plant: Facts and Figures
Up to 135,000 tonnes of waste incinerated each year
The plant heat input is 44 MW
The plant generates 180–190 GWh of district heat and approximately 72 GWh of electricity each year
The plant has halved the carbon dioxide emissions of district heating production in Salo
