What happens when rising energy prices and carbon pressure force a rethink of how sludge is treated? This paper by Keith Panter, Managing Director at Ecbor Ltd. explores how UK utilities shifted away from energy-intensive raw sludge drying and towards advanced anaerobic digestion with thermal hydrolysis (THP), unlocking both economic and carbon benefits in the process. Using full-scale projects at NWG (Northumbrian Water Group) and Dŵr Cymru Welsh Water, it shows how combining THP with digestion: ✅ Changes the energy balance of sludge treatment ✅ Increases biogas yield and dewaterability ✅ Reduces reliance on thermal drying The findings reinforce a simple but powerful idea: In an energy-constrained world, sludge should be an energy provider, not an energy user. 📥 Download the full paper via the link in the comments. #AnaerobicDigestion #SludgeTreatment #EnergyFromWaste #Decarbonisation #EnergyEfficiency #CircularEconomy
