Recycling of lightweight concrete

Pilot plant paves the way to the future

Implementation of a zero-waste economy requires feeding back of secondary raw materials into subsequent production runs, which is one of the major challenges all raw material processing industries are facing. This is particularly true for the German construction industry, which consumes mineral raw materials in large quantities whilst also generating the biggest waste stream.

From a scientific and engineering point of view, lightweight concrete opens up the potential for establishing a closed material cycle. For this purpose, further advances need to be achieved in the development of recycled...
