Plasma technology retrieves precious metals from e-waste

Plasma technology retrieves precious metals from e-waste: Tetronics International is aiming to address the growing issue of electronic waste by using plasma to recover precious metals from the debris.

Tetronics’ clean plasma technology turns old electronic devices into
value by extracting precious metals such as gold, silver, copper and tin
whilst eliminating the hazardous materials.


The heat and ultraviolet light properties of plasma, an ionised or
electrically charged gas, are designed to smelt and separate precious
metals in a furnace, whilst destroying any harmful elements. A
non-hazardous vitrified material is left behind, which the company calls
Plasmarok and which can be used as a building material for the
construction industry.



Very interesting technology,
