Our multi-partnership consortium, led by Yorkshire Water, identified Advanced Thermal Conversion (ATC) Gasification as an alternative approach to ‘Sludge to land’. This will allow us to prove the technical and economic viability of gasifying 100% sewage sludge and provide the water industry with the confidence to exploit the technology globally. 

“We have identified innovative uses for sewage sludge. Converting it into gas, biochar and ash ‘stones’ opens up new, more sustainable and low carbon ways to reuse sewage sludge. 

Once proven, the process will produce sustainable wastewater treatment media, construction materials and high-value products and generate heat and power.” – Dr Danielle Hankin, Innovation Programme Manager, Yorkshire Water
