  • Plasma arc waste recycling A simple introduction

    May 07, 2020· Plasma arc recycling doesn't involve combustion. Instead of simply burning the waste (at a few hundred degrees), the waste is heated to much higher temperatures (thousands of degrees) so it melts and then vaporizes. This is done by an electrical device known as a plasma arc, which is a kind of super-hot "torch" made by passing gas through an
