More than half of the total waste volume worldwide is caused by construction waste such as asphalt demolition material, excavated soil or demolition debris. Sinking landfill opportunities, rising disposal costs and the increasing scarcity of raw materials demand more and more sustainable and environmentally friendly solutions in the construction industry.

Construction and demolition recycling as well as material processing are already major profit factors for many companies in the construction market.
The reclamation of construction debris and the processing of virgin stone are a guaranteed step towards success for the modern contractor.

Four grand advantages of professional mobile C&D recycling and processing:

  • No deponie fees
  • No transport costs thanks to on-the-site processing
  • No additional costs incurred for costly virgin material
  • Increased profit through resale
