Sewage Sludge Fuel Production Technology Using Carbonization Furnace with an Electrically Heated Screw Conveyor

Abstract

For sustainable development, there is growing demand for waste biomass utilization. In order to meet such social needs, we have demonstrated “sewage sludge fuel production technology using carbonization furnace with an electrically heated screw conveyor” for the purpose of energy utilization of sewage sludge. And we have confirmed that the technology can produce sludge fuel with a stable calorific value and save energy. Based on the results of this demonstration, the technology was evaluated and authorized in “JS innovation program” by the Japan Sewage Works Agency.
