E-waste Processing Plant

For over 30 years, weeeSwiss has been developing and implementing customized recycling processes for all types of electrical and electronic waste – successfully operating worldwide.

Our plants are designed to efficiently remove hazardous substances from e-waste and separate it into high-quality materials and raw resources. A particular focus lies on the concentration of precious metals, ensuring that subsequent pyro-, hydro-, and electrometallurgical processes are as efficient as possible.

The Recycling Process at a Glance

The process begins with weighing, inspecting, and classifying the input material, followed by allocation to the appropriate processing units.
Hazardous substances are removed both manually and mechanically. A proprietary process developed by weeeSwiss – and continuously improved since 2000 – significantly reduces the amount of manual effort required.
Extracted hazardous substances are safely stored and handed over to certified disposal specialists – always in parallel with the recovery of valuable materials.
Our modular plants allow for precise shredding, achieving the desired grain sizes while ensuring that pollutants can still be removed after shredding.

The Ballistic Separator

A central element of the process is the ballistic separator:
In a single step, it separates 2D, 3D, and fine fractions. This allows plastics to be selectively removed immediately after coarse shredding, relieving downstream modules.
The material then undergoes further screenings and manual sorting before being shredded again. This enables the extraction of ferrous and non-ferrous metals and, in particular, high-quality plastics.

Maximum Recovery of Valuable Materials

In the next stage, sensor-based sorting divides the material into further fractions such as printed circuit boards and plastics.
Remaining materials are reprocessed within a closed-loop system – right up to complete liberation in the granulation mill.
Granulation Module 4 plays a key role in releasing precious metal–bearing fractions. Our process is highly energy-efficient and low in wear, reducing heat development within the material. This enables plastics to remain recyclable even after milling.
Our modern dedusting systems not only ensure clean and safe working conditions but also enable the recovery of the finest precious metal particles – another important contribution to resource conservation.
