Treatment of airborne asbestos and asbestos-like microfiber particles using atmospheric microwave air plasma

► We use atmospheric microwave air plasma to treat ceramic fiber and stainless fiber as asbestos alike micro fiber particle. ► Spheroidization of certain type of ceramic fiber and stainless fiber particle. ► The evaluation of the treated particles by the fiber vanishing rate. ► Good fiber vanishing rate is observed for fiber particle with diameter below 10 μm. ► The treatment of pure asbestos and a suggestion of the use of this method for the treatment airborne asbestos.
