Hydrothermal processing
Catalytic Hydrothermal Gasification Of Sewage Sludges For Renewable Biogas And Pollutant Mitigation
Short Introductive summary
Catalytic hydrothermal gasification (cHTG) efficiently converts wet organic waste into renewable biogas under supercritical water conditions. Within the Mocopée project, two SIAAP sewage sludges from the Seine Aval and Seine Grésillons plants were evaluated on a continuous pilot unit at PSI. The tests demonstrated effective conversion of sludge organics into methane-rich biogas and investigated the fate of persistent pollutants such as PFAS, PCBs, and PAHs, confirming the potential of cHTG for sustainable sludge valorization.
