Opalis Germany Mapping the German Salvage Business

Opalis is an ongoing research project set up in 2011 to document traders in used building materials. The website has so far provided access to companies from Belgium, the Netherlands, France and the UK. This summer semester 2022, a group of architecture students from KIT started to develop the map in Germany. As part of the guest professorship "Sustainable Materials", more than 50 traders were visited and interviewed in a series of research trips. In the exhibition, the collection of research will be presented to the public for the first time.
