1 Context

Due to the use of increasingly complex composite materials in the construction industry, future technological criteria for the preparation of mineral-based construction and demolition waste will have to become more stringent in order to confine such waste to closed substance cycles. This will apply in particular to disintegration and automated sorting processes. Recycling plants, as raw material suppliers, must be equipped with suitable technology for producing pure, unmixed materials, i.e., recycling products containing only a small fraction of impurities or interferants.
