The overall aim of this project is to promote the Nordic countries as a forerunner region in demanding and using sustainable design of batteries for consumer electronics and the transport sector, and to identify key opportunities, barriers and challenges in the transition towards a more sustainable use of battery technologies. The aesthetics of the design should meet with the overall sustainability: high quality, durability and smart assembly for refurbishing.The project is funded by the Nordic Working Group for Circular Economy (NCE) under the Nordic Council of Ministers. The project has been carried out by Viegand Maagøe A/S (Denmark) and IVL Swedish Environmental Research Institute (Sweden) in the period 20 October 2020 to 31 December 2021.A reference group with representatives from the Nordics has been established, who provided valuable input to the study.
