Sorting Plants for Electrical and Electronic Waste

Sorting plants for the so called "e-waste" are required to satisfy the highest demands: before separating different types of metals and plastics, it is also necessary to detach the valuable materials through shredding and classifying out of the composite of different materials, 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 electrical devices and electronic components of all sizes and categories. Be it big and small household appliances, mobile phones, computers, printers, monitors, televisions, refrigerators and air conditioning systems.

Example process description

All electronic and electrical equipment is first freed of pollutants and is then further shredded. This is followed by mechanical sorting in several stages, during which iron, non-ferrous metals and plastics are separated from each other. The pure fractions are partly pressed and sold on to steelworks, smelters and plastics recyclers.
