Not true about Screw feed technique is: (A) 80% volume reduction, (B) Pathological waste are removed, (C) Weight is decreased by 20-30%, (D) Based on non-burn thermal treatment
Answer is B. SCREW-FEED TECHNOLOGY: Principle: Non-burn dry thermal process Process: Shredding of waste Heating in a rotating auger Reduction in waste: Reduction in weight: 20-35% Reduction in volume: 80% Useful for wastes: Infectious waste Sharps Not useful for wastes: Pathological waste Cytotoxic waste Radioactive waste Ref: Park 25th edition Pgno: 828
