The mineral part of the waste replaces primary mineral materials (such as limestone, clay or iron) and the combustible part provides the energy needed for the clinker production. As a result, 100% of the waste input is recycled or recovered without producing any additional residue. The technology used also ensures a performing destruction of toxic components.
Co-processing achieves a superior environmental performance as compared to landfill and incineration which is demonstrated by life-cycle assessment studies.
Co-processing is recognized by the UNEP Basel Convention as a practical, cost efficient, safe and environmentally preferred option compared to other waste treatment options.
