Metal / Electrical and electronic waste

Metal has excellent material properties and it can be recycled as often as desired!

Metal recycling not only ensures  the supply of value resources to the respective industry . Recycling makes a significant contribution to the environmental protection when it comes to saving energy, conserving primary resources and the reduction  hazardous substances emissions. In order to make recycling as efficient as possible, it is important to remove impurities from the actual recycling materials ​​​​​and to sort into individual material groups like basic alloys and sub alloy groups as far as possible by mechanical sortingWith optimised sorting technology, the use of valuble resources in the smelter or mill can be extremely reduced and even entire process steps such as hydrometallurgical refinery can be skipped. Typical customers include copper/brass refineries and aluminium or steel mills respectivly. The most important thing is, that the concentrated recycled metals  show the highest achievable purities.

Our sorting technologies for metal recycling

Our solutions with sensor based sorting

  • Inductive sensors for detection of metallic parts
  • VIS sensors for selectivities in visible light
  • NIR sensors for material characterisation based on specific absorption behaviour
  • LIBS sensors: Metal and alloy group classification based on chemical analyses.
  • AI technology: Algorithmic add-on to enhance signifantly the classification of materials with almost non visible differences  
  • Sensor Fusion: We can combine different sensor technologies to generate the best possible sorting result

 

Tasks

+ Recovery

of metallic parts, which cannot be recovered by conventional processing such as magnetic separation and eddy current separators.

+ Sorting according to optical properties such as colour and shape

  • Sorting of red metals from grey metals
  • Separation of non-metallic impurities (e.g. plastics, organics).

+ Sorting of alloys and base matels by means LIBS

Sorting based on chemical composition of metals scrap. Enables sorting into different base metals and alloy groups.

  • Sorting from Twitch into cast and wrought aluminum
  • Sorting of wrought alu into main alloy groups 1xxx, 2xxx, 3xxx, 4xxx, 5xxx, 6xxx, 7xxx, and 8xxx
  • Sorting from mixed heavy metals in to copper alloy groups and others
  • Sorting of stainless steel into different alloy groups according to chemical composition

+ Sorting in the near-infrared range:

Sorting of technical polymers typically used in cases of electrical and electronic equipment.

+ AI/Artificial Intelligence

Colour sensitivity optimized cameras and highly complex software algorithms allow sorting solutions for tasks that were previously considered feasible. Even the smallest optical differences are sufficient to achieve automatic classification with extremely high reliability:

  • Sorting on the basis of characteristic surface structures (PCB, partially oxidised metals)
  • Sorting on the basis of complex shapes (standardized parts like screws, washers etc., plugs and conectors).
