Incineration Technology of Bone Waste Using Thermal Plasma

The meat consumption produces a lot of bone waste everyday. Dumping bone waste without treatment results into environmental hazards. Conventional treatment by pyrolysis is slow, inefficient and produces hazardous by-products. In the work, an investigation of bone waste incinerated using thermal plasma technology is presented. A high temperature arc plasma torch operated at 33 kW was employed for the experiments. Bone waste was incinerated to remove the infectious organic matter and to vitrify the inorganic matter using plasma torch. Bone waste was reduced its 2/3 weight after the treatment. The process was highly efficient, economical, convenient, and fuel free. This method could be used as an alternative method for disposal of bone waste, small infectious animals, hazardous hospital waste, etc.
