Choose an efficient solution

  • Energy saving
    Energy-positive process: burning the CLEEF biofuel produces more energy than consumed
  • Minimal nuisances (odor, transportation)
    Thanks to this process, the water transportation is highly reduced. Due to the cooking process the smell is reduced to the very minimum
  • Space usage
    The equipment is space-saving and an easy and stable storage for the product is guaranteed
  • Ressource-efficient
    The decarbonised water goes back to the WWTP and all the carbon contained in the sludge is converted to biofuel

An alternative and competitive solution to composting, thermal dryers and incineration : illustration titre

  • Minimal operation costs compared to other treatment and recovery solutions
  • A positive energy balance compared to all other solutions

Respect of the legal frameworks illustration titre

  • The implementation of the CLEEF process on a WWTP does not modify the existing legal framework on site

1 tonne


The production of 1 kg of biofuel consumes 0,4 kWh using the CLEEF process. 1 kg of CLEEF biofuel produces 7,5 kWh of thermal energy.


1 tonne


A 1 ton per hour CLEEF equipment covers an area of 200 m².
