Evac - Model HydroTreat -Organic Wet Waste Onboard Vessels
Evac HydroTreat is an innovation that revolutionizes the handling of organic wet waste onboard vessels. The novel innovation remarkably decreases the vessel’s environmental footprint; it provides a safer, more sustainable way to deal with organic waste streams, such as food waste and bio sludge, without emissions or plastic waste to the sea or gas emissions into the atmosphere.
The hydrothermal carbonization (HTC) process for wet organic waste handling transforms food waste and biosludge into biochar. The biochar is sterile, stable, and easy to store onboard the ship while offering several opportunities to be utilized once landed.
- Game-changing product for organic waste treatment
- No harmful emissions into the atmosphere or sea
- Available for passenger vessels of most 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.
