Delivered construction materials are subject to a visual, documented input control before being processed and reused. This guarantees that only non-toxic, uncontaminated raw material is passed on for processing. Neither rubble containing pollutants or contaminants nor excavated soil can be accepted at the Himberg facility.
The degree of impurity in the delivered material is determined based on the proportion of foreign substances such as mortar, wood, or plaster. Materials such as insulation, plaster, wood wool (Heraklith), earth, porous concrete (Ytong), etc. cannot be processed by our Himberg facility. Non-recyclable material that has been separated out is sent for professional disposal. Once the input controls have been completed, the material is processed by special sieving and crushing machinery.
