In the Lapland region, the goal has long been to increase the low-carbon and resource efficiency of operations and services. Studies and measures for the development of low-carbon services in the Arctic have focused, among other things, on tourism, the utilization of natural resources and the resource wisdom of construction. The connection of the circular economy and low carbon to steel construction has so far been less, due to the linkage of implementation to large-scale processes. In the implementation of the steel structure, the formation of the carbon footprint is affected by e.g. materials used, manufacturing steps and energy consumption. However, the carbon construction of the future requires the most carbon-neutral operation possible. According to studies, the re-use of steel structures is most limited by general ignorance and, for its part, by potentially insufficient material properties. There has been a clear need in the steel construction industry to develop a streamlined process and tool for calculating the carbon footprint of micro and SMEs. This also involves raising companies' awareness of the principles of the circular economy, life-cycle thinking and reducing the carbon footprint. The aim of the project is to develop the industrial circular economy in the Lapland region, investing especially in steel construction, the availability of materials and the circular economy. The project will carry out extensive familiarization with steel construction, both in terms of documents and standards governing construction and in accordance with the principles of the circular economy. The project will also carry out an extensive survey of issues related to reducing the carbon footprint and improving energy efficiency. The carbon footprint process creates a calculation tool that is demonstrated in the learning and RDI environment related to steel construction at Lapland University of Applied Sciences. The results obtained from the demonstrations will be utilized and implemented in SMEs specializing in steel construction in the Lapland region. The project will support and activate the innovation activities of SMEs and their capacity to utilize creative know-how. The project will support the innovation activities of SMEs, in particular by bringing a calculation tool from the carbon footprint process to steel construction and the availability of materials. The calculation tool can be used to develop the SME ecosystem, knowledge clusters and networks.
