Recycling plants for electrical and electronic scrap

For each type of electrical and electronic waste ANDRITZ MeWa offers individually tailor-made plant solutions, which meet all requirements of the European WEEE Directive. With the Universal Cross-flow shredder QZ, ANDRITZ MeWa has developed a particularly effective and environmentally friendly technology, which has led the way throughout Europe, for recovering the recyclable materials and separating out the hazardous substances.

The Universal Cross-flow shredder QZ as centerpiece of the e-scrap recycling plant breaks up gently the input material. That way the material composites are broken-up and assembly groups are freed. Batteries and capacitors remain intact whereby the material stream remains clean. Directly after the processing in the QZ approximately 80% of the input material can be separated manually, automatically or optoelectronically and is directly available for selling-on.

Input materials - Examples

  • Household equipment
  • Computers
  • Copiers
  • Washing machines
  • Dryers
  • Consumer electronics
  • Small appliances

Process steps of the e-scrap recycling plant

3D model of an e-scrap recycling plant

Throughput of the plant: 2-15 to/h (depends on size of the machine and material mix)

Key components: Universal Cross-flow shredder QZ



  • Printed circuit boards
  • Transformers
  • Capacitors
  • Aluminum
  • Copper
  • Iron
  • Stainless steel
  • Plastics


Benefits (in comparison with cutting systems)

  • QZ with accelerating tools for breaking the material bounds, based on the different material properties
  • Wide range of possible input materials
  • Most of the circuit boards remain intact and available to be sold to a metal foundry
  • Size and form determined by the operating parameters of the QZ
  • Faster and more efficient sorting of the valuable materials and contaminants
  • Materials remain in coarse pieces, mostly separated from each other
  • Easy to sort out valuable ferrous and non-ferrous fractions like motors, transformers, Fe/Cu compounds, copper, aluminum, cables, plastics
  • Less wear and tear and higher availability of the following equipment due to early removal of disturbing and coarse parts
  • Massive parts can also be processed without causing damages to the accelerating tools
  • No release of harmful substances because of gentle dismantling of batteries and capacitors


Option: Further granulation step for higher recycling rate

Key components: Universal Granulator UG

  • High purity degree of output fractions through further destruction of remaining material bounds
  • Homogenized distribution of output size and form
  • Customized grain-size, end products adapted to market demand
  • High efficiency of the separation technique when granulated material is processed, higher recovery rate of valuable resources
  • In-house integrated recycling solution from A to Z for gaining best value from input material
  • High capacity because of higher quality and less quantity of material flow to the granulation step after QZ treatment
Input for e-scrap plants

All types of e-scrap can be treated in ANDRITZ MeWa recycling plants.
