Recovery of Precious Metals from E-Waste using Clean Plasma Technology

Dr Tim Johnson will discuss the benefits of plasma technology as a clean solution for recovering valuable precious metals from the world’s fastest growing waste stream – e Waste.

The heat and ultra-violet light properties of plasma technology are perfect for smelting and preferentially separating the precious metals contained with the electronics waste, whilst also destroying any hazardous elements. The remaining waste material is then vitrified into resalable building product called Plasmarok®.
