Sludge Reduction & Valorization

Sludge Reduction & Valorization

Prepared and Tested

The hydrothermal conversion process transforms the waste into a solid carbon material, the hydrochar, which can be used:

  • as a biofuel for the production of energy.
  • as soil improver;
  • as Advanced Carbon Material, in particular as an adsorbent of pollutants in water and gas.


What is Hydrothermal Conversion (HTC)?

  • HTC is a process that destroys the colloidal structure of the sludge permitting to the «Bound water» to become «Free water»
  • In this way, HTC technology permits to easily dewater the sludge!
  • As a consequence the volume of sludge going to landfill will be much lower respect the current situation

Technology Benefits

  • Replication of the HTC Process Conditions
  • Possible to use with all types of Sludge both for HTC and HTL


This is an electrical filter press that automatically could treats Sludge/Slurries. The Operative Conditions then will be replicated in the scaled-up system.
