If buildings are built according to the Cradle to Cradle® principle, they become long-lasting raw material depots that return resources in a targeted manner. Just like in nature, where waste is not left behind, but becomes nutrients for something new.
The Circularity Passports® Building or material passport records building products and materials, their ecological footprint, recyclability and the value of the materials used.
Heidelberg wants to become a circular city. In the Patrick Henry Village pilot project, urban mining is to be practiced in existing buildings. The starting point was set with the Urban Mining Screener program developed by EPEA and the Madaster building database.
