Hydrothermal carbonisation

Hydrothermal carbonisation (HTC) converts sludge predominantly into a carbon-rich hydrochar solid product. The process is conducted at temperatures generally between 180 and 300 °C, with corresponding pressures above 10−88 bar to ensure that the water is maintained in the liquid state. Reaction times ranging between 0.1 and 4h have been employed. The precise conditions of temperature, pressure and time selected depend both on the feed sludge quality and the target yield and characteristics of the hydrochar product.

How do you solve a problem like PFAS?

PFAS (per- and polyfluoroalkyl substances) are generated from the breakdown of fluorinated polymers. The activation barrier for their breakdown is huge and the only fully commercialised processes possibly capable of destroying PFAS are thermochemical ones.
