Sorting Plants for Electrical and Electronic Waste

Sorting plants for electrical and electronic waste are required to satisfy the highest demands: in addition to separating different types of metal, it is also necessary to detach the metals from valuable plastic sheaths and coatings, and subsequently feed them into the recycling loop.

STADLER experience

“Working in cooperation with weeeSwiss Technology AG (which has been active in the field of electronic and electrical waste for over 25 years now), STADLER develops high-quality sorting plants for electrical waste which are unrivalled in terms of sorting quality and throughput.”

Material properties

The material mix in the field of electronic and electrical waste includes a wide variety of electronic devices of all sizes. Be it mobile phones, computers, printers, televisions or blenders, refrigerators and air conditioning systems.

Example process description

All electronic and electrical equipment is first dismantled and then shredded. This is followed by mechanical sorting in several stages, during which plastics and the fine fraction are separated from each other. Separation into different plastic and metal fractions then takes place. The pure fractions are finally pressed and sold on to steelworks, smelters and plastics recyclers.
