Maximum innovation in Environmental and Recycling Technology

InnoMax is a consultancy with over 35 years of experience in the recycling industry, both nationally and internationally. Director Cees Duijn works as an advisor and is your point of contact when it comes to services relating to the reprocessing and recycling of residual and waste materials into secondary raw materials and fuels.

As a consultant for Environmental and Recycling Technology, Cees is involved with companies all over the world. He advises, contributes his knowledge and experience and thus has clear added value for his clients. From processing to complex waste flows, Cees knows better than anyone which route to take to get more out of waste and optimize processes.


His specialism lies in the design, development and realization of projects related to the upgrade, recovery and recycling of waste and residues in secondary bulk / construction materials, raw materials for reuse and fuels for alternative energy generation.

Specific know-how and expertise includes the following residual and waste materials:

  • Household Waste (HA)
  • Commercial Waste and Bulky Household Waste (BA and GHA)
  • Construction and Demolition Waste (BSA)
  • Waste Energy Plant (AEC) Bottom ash
  • Landfill Rehabilitation and processing of excavated waste
  • Mattresses
  • Rubber car tires, truck tires and tractor tires
  • Coal Fly Ash and AEC Fly Ash


In addition, Cees has many projects to his name where his expertise in recycling technology and air technology has resulted in a number of inventions and patents that have been beneficial to the environmental and recycling industry. The recycling world is changing rapidly, and precisely then the knowledge of an expert with a proven track record is of great importance for organizations.

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

  • Air technology, heavy / medium / light separation in particular:
    • Wind shifter-Unit (WZU)
    • Lift shifter-Unit (SZU)
  • AEC bottom ash reprocessing and stabilization
  • Coal fly ash reprocessing into a cement substitute


The “new” recycling generally means the recovery of raw materials from waste. Residual flows must be processed as efficiently as possible, so that there is a good balance between costs and savings.
