Treatment of Bone Waste Using Thermal Plasma Technology

摘要

Dally meat consumption produces a lot of bone waste,and dumped bone wastewithout treatment would result in environmental hazards.Conventional treatment methods ofwaste bones have some disadvantages.Herein,an investigation of bone waste treated using thermalplasma technology is presented.A high-temperature plasma torch operated at 25.2 kW was usedto treat bone waste for seven minutes.The bone waste was finally changed into vitric matterand lost 2/3 of its weight after the treatment.The process was highly efficient,economical,convenient,and fuel-free.This method could be used as an alternative for disposal of bone waste,small infectious animals,hazardous hospital waste,etc.
