Since the post-war period, we have been surrounded by an anthropogenic  warehouse of over 50 billion tons of material. This warehouse grows  every year by another 10 tons per inhabitant. Much of it is located in  buildings. Wouldn’t this warehouse be a potential resource for the  construction industry of the future? In the new episode of Fighting 40%-Podcast is this the question we discuss with our guest Professor  Dirk Hebel. Tuesday, 8 p.m. on stream and UKW 104.8.
