The recycling world is changing rapidly and precisely then the knowledge of an expert with a proven track record is of great importance to organizations.

Specialist knowledge for the reprocessing of waste lies in the various technological developments, inventions and patents realised by Cees Duijn:


  • Air technology, heavy/medium/light separation in particular:
    • Wind Shifter Unit
    • Vertical Air Separator


  • Reprocessing and stabilization of waste energy power plant soil ash
  • Reprocessing coal fly ash to cement replacement



The ‘new’ recycling generally means the recovery of raw materials from waste. Residual flows need to be processed as efficiently as possible, so that a good balance between costs and savings is created.
