Quality assured disassembly of electronic components for reuse

Waste Printed Circuit Boards recycling: an extensive assessment of current status

“…The image processing and database are adopted to identify the different components and later, different PLC modules can be used in designing further route for dismantling. Many approaches have been reported for automatic (Knoth et al, 2002;Stobbe et al, 2002;Yokoyama et al, 1999) or semiautomatic disassembly (Knoth et al, 2000;Zebedin et al, 2001) but till now, manual disassembly is the most common technique adopted in most of the recycling plants. The application of different disassembly techniques for PCBs has been extensively reviewed by Li et al (2004), where it is reported that automatic disassembly process can be more economical than manual one.…”

Examining the technology acceptance for dismantling of waste printed circuit boards in light of recycling and environmental concerns

“…A flexible automated cell for PCBAs dismantling has been proposed and described in several publications (Zebedin et al, 2001;Knoth et al, 2002;Stobbe et al, 2002;Brandstotter et al, 2004;Yi et al, 2007). First, the PCBAs are fixed on frames and fed into the dismantling cell.…”

The reuse of electronic components from waste printed circuit boards: a critical review

“…Iannicelli-Zubiani et al 41 evaluated the process of treating 100 kg of WPCBs using hydrometallurgy and found that the process had an impact on global warming (GWP100a) of up to 7.02 × 10 2 kg CO 2 eq. Compared to material recovery, reusing refurbished and recycled components in reworked or new products can reduce costs and develop new business areas, can reduce further consumption of resources by new products, and can reduce the land occupation 42 . By recycling and reusing, potential environmental pollution from WEEE can be reduced or mitigated, while also achieving the goal of a "second life" for WEEE 39,43 .…”
