Abstract Background Owing to the large amounts of energy, greenhouse gases, and waste that it generates, construction industry is fundamental transition towards a circular economy. Indicators which show circularity products—and thus make them comparable with each other—can be used support implementation such an In this article, we have adapted material indicator Ellen MacArthur Foundation in order analyze products available German environmental database ÖKOBAUDAT. Results The applied 89 building from categories insulation materials, plastics, metals, mineral materials. More than half receive lowest score 0.10, indicating poor strategies date.
