Circular construction with AAC—recycling of an industrial hall made of Hebel elements in Munich‐Puchheim

Abstract

AbstractIn Germany, construction, and demolition waste accounts for more than half of the waste generated, which means that valuable raw materials are lost for high‐quality recycling. But there is a solution: switching to a closed material cycle in which discarded products are reprocessed so that they can be used to manufacture the original or at least an equivalent product. A pilot project near Munich in Germany is demonstrating how discarded Xella products can be recycled into new products of equal value—with pioneering results. An old industrial hall made of prefabricated Hebel AAC‐wall elements was demolished, the material collected and processed into AAC powder, which was subjected to the production of new AAC. In the meantime, a new hall made of AAC has been built on the same site.
