The use of peat has had a clear foothold in Finnish energy production, but there is an urgent need to find more climate friendly solutions to replace peat. Nationally, the goal is to halve the use of peat in energy production by 2030. In addition to renewable energy sources, alternatives to peat-produced energy include the utilization of already existing waste heat generated in processes and the built environment. The goal of this project is to create information for SMEs and organizations in the Lapland region about the unused energy potential, and how this energy potential can be used more efficiently. The purpose of this project is to recognise the waste heat potential and the most common sources of waste heat in the Lapland region, as well as to collect and create information on waste heat utilization methods. Project will create an up-to-date picture of the waste heat generated in Lapland. New information is created by studying pilot cases to recognise how to utilize the waste heat generated in buildings and production plants and what financial opportunities there are. Since the different sources of waste heat and their utilization differ a lot, separate action groups are formed for them: 1) industrial waste heat 2) large buildings 3) farms and 4) other solutions. The project involves national cooperation and finds best practices and innovative technologies to optimize waste heat operations, reduce the carbon footprint and improve energy efficiency. The goal is to expand cooperation internationally. The utilization of waste heat and related technology etc. also benefit the Baltic Sea regions. As a result of the project, climate change mitigation measures will be obtained, which will have a positive effect on the well-being of the Baltic Sea region. By promoting the utilization of waste heat, jobs can be created and resources can be avoided. The waste heat of wastewater is a key issue to be investigated. The goal is to support the transition from the energy use of peat by mapping the main waste heat sources and quantities in the Lapland region, and to find out the technical and economic possibilities of using waste heat in the project's pilot cases. The waste heat mapping and piloting of this project support SMEs operating in the energy and building sector by clearing a path towards greener energy production. The project also creates an even closer dialogue between SMEs and RDI operators in the field. The project's activities strengthen Lapland's business life related to energy efficiency and promote the transition away from fossil energy sources.
