Obsolete PCBs Sorting

Pilot 4 addresses the challenge of sorting and valorising obsolete printed circuit boards (PCBs) recovered from electronic waste. PCBs contain valuable materials such as copper, gold and semiconductors, but efficient recovery requires advanced identification and sorting methods.

PCBs are the backbone of electronic devices, connecting components and enabling electronic functionality. However, PCBs are also one of the most challenging elements to recycle due to their complex composition and the presence of valuable but difficult-to-extract materials.

Pilot 4 focuses on improving the sorting, identification and valorisation of obsolete PCBs recovered from electronic waste streams. By developing advanced sorting techniques and digital tools for analysing materials and components, the pilot aims to improve the efficiency of electronic waste recovery systems. The pilot also demonstrates how reverse supply chains can be organised to enable the recovery and reuse of electronic components, supporting more sustainable management of electronic waste.

Objectives

The pilot aims to:

  • Develop advanced techniques for identifying and sorting obsolete PCBs.

  • Improve recovery of valuable electronic components and materials.

  • Support reuse, refurbishment and recycling strategies for electronic waste.

  • Demonstrate digital tools that improve traceability and circular supply chains.

Key Activities

Activities implemented within the pilot include:

  • Characterisation and analysis of PCB materials and components.

  • Development of digital tools for material identification and circularity analysis.

  • Integration of recycling simulation tools to evaluate end-of-life scenarios.

  • Collaboration with recycling companies and electronics manufacturers.

These activities help create efficient reverse supply chains for electronic components and materials.

Results

Key achievements include:

  • Improved sorting methodologies for obsolete PCBs.

  • Identification of reuse opportunities for recovered electronic components.

  • Demonstration of circular supply chain models for electronics recovery.

  • Enhanced collaboration between recycling and manufacturing sectors.

Impact

This pilot contributes to improving the management of Waste from Electrical and Electronic Equipment (WEEE) and supports the development of circular value chains for electronics. By enabling better recovery of materials and components, the pilot reduces reliance on primary raw materials and strengthens Europe’s resource resilience.

Relevance for SMEs

Many SMEs operate in the recycling, electronics refurbishment and materials recovery sectors. The technologies and methodologies demonstrated in this pilot can help these companies improve the efficiency and profitability of their recycling operations.

Improved PCB sorting and component recovery also create opportunities for SMEs to develop specialised recycling services, component reuse businesses and secondary materials markets, contributing to a more resilient and sustainable electronics ecosystem.
