sorting & classification
PDF Print E-mail

Waste never corresponds to a unique specification. Every single product model has its own composition - and turns a waste stream to an unpredictable mixture of materials. This is also true for PV Panels, which could exist as:

  • thin film Cadmium-Telluride or CIGS or
  • mono- or multi-crystalline Silicon Wafer type.

The battery world is even more complicate. More than 10 different standard categories are put on market, namely:

  • Alkaline (ZnMn)
  • Zink-Carbon
  • Zink-Air
  • Nickel-Cadmium
  • Nickel-Metalhydrid
  • Mercury-containing cell
  • Lead-containing cell
  • Silver-Oxyde
  • Manganese/Mg-Ion cell
  • Li-primary cell with approx. 10 subtypes (TCl, SO2, MnOx, etc.)
  • Li-Ion secondary cell with approx. 8 subtypes (CoO, NCM, MnO, NCA, etc.)

In addition to this, the process requirments of final recycling facilites are changing sorting critera from time to time, which needs to keep sorting process as flexible as possible. Due to these complex challenges, no fully automatised sorting technology does exist in Europe today. Accurec still relies on manual sorting and has trained a specialised team for exact identification of battery types and chemistries. Accurec´s X-Ray lab is supporting a fast and sustainable training. In addition, accumulators are more and more used for power supply of electronic devices, and extracted from WEEE-treatment. This group of batteries frequently misses any labelling or marks. Based on conducted analysis, comprehensive data sets and knowledge of sorting team, it is a unique characteristic of Accurec to classify discarded batteries correctly and with high reliability. A basic precondition to optimize recycling processes to a higher efficiency in metal recovery.
