Wet waste treatment

Evac HydroTreat

Evac HydroTreat® is a novel innovation based on Hydrothermal Carbonization (HTC) that transforms organic waste generated onboard ships into biochar. Our process does not produce any harmful emissions into the atmosphere or to the sea and is extremely energy-efficient to operate. The biochar is sterile and stable, and easy to store onboard the ship while offering several opportunities to be utilized once landed.

  • Game-changing product novelty for organic waste treatment
  • No harmful emissions into the atmosphere or sea
  • Available for passenger vessels of all sizes

  • No emissions into the sea or to the atmosphere
  • Extremely energy-efficient process
  • Turns waste into a valuable product

Modular design, suitable for passenger vessels from approx. 500 people on board all the way to ships with 8000 people on board.

In hydrothermal carbonization (HTC), wet organic waste is processed at temperatures of approximately 200 °C. The heat causes a chemical reaction, where the waste materials break down into a solution with loose water and material commonly known as biochar. The water can be mechanically dried, leaving two streams – water and dry solid biochar. The water can be treated in the ship’s existing AWWP, and the biochar is easy to land when the ship comes to port.

The heat in the system is retained with heat exchangers, making the system extremely energy efficient to operate. HTC is a non-incineration process, meaning no exhaust gases are generated in its operation. With an easily scalable modular design, the Evac HydroTreat is a suitable solution for passenger vessels of almost all sizes.
