Processing construction waste

Professional recycling for construction materials.

A variety of building waste types can be processed and transformed into quality products at our multipurpose Himberg facility.

We produce CE-certified construction materials in accordance with legal requirements and subject to strict in-house and external controls. By processing mineral materials, we contribute to saving natural resources and help ensure sustainable use of raw materials.

Our processing facilities recycle mineral construction waste, brick and concrete rubble according to professional standards.

Input controls guarantee product purity.

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.

Production of high-quality brick sand and crushed brick.

Brick rubble is processed by a state of the art stationary plant. Here, the material is sieved by machine, manually sorted, and then washed and crushed. Any unwanted foreign substances (e.g. wood, plaster, metal) are separated out of the stream of material and diverted for separate recycling. The crushed raw material is then sieved into the various grain sizes.

Our other plants process concrete rubble and mineral building waste. This material is then stored temporarily before continuing its lifecycle. It is necessary to separate out unsuitable building materials; this is done by machine, using the latest technology for sieves, air separators and magnetic separators. The final step is a manual sort carried out by our employees to remove any remaining unsuitable materials.
