Description: Objective: Most European waste management strategies include substantial increase of energy recovery from wastes at lower cost than at present. It this context one critical issue is sludge treatment. In order to use sludges in gasification or fluidised bed incineration processes which offer highest energy recovery, sludges need to have greater 85 per cent dry content. Mechanically dewatered sludges have 40-50 per cent dry contents today and need extra -400 MJ/ton of dry sludge for incineration. The project aims at developing an innovative mechanical sludge treatment system with integrated crushing - dewatering - pelletizing based on a special screw extruder. The dewatering reaches 85 per cent of dry contents and greater 90 per cent by simple steam release of pellets. Similar concepts had failed in the past but recent technical advances enabled SME proposes to prove the feasibility. Together with researchers, engineering companies and end users e.g. in pulp and paper and waste recycling they want to develop an industrial system.
