Solution approach

It consists of three process steps: The first step is the processing of the demolition material. The demolition material is sorted at high throughput rates by a recognition process based on optical computing. Special attention is paid to ensuring that the optical filter used permits high selectivity during sorting and that the various influences are taken into account. The processed material is then analysed and certified according to certain standards. This process is carried out in order to generate a material with defined and consistent quality. Following the certification process, the material obtained is used for new construction projects. This ensures the efficient use of any demolition materials that are produced.
