EU strategies for waste management have long recognized the key role of recycling to move towards sustainable consumption and production. This resulted in a range of regulatory measures, among which the Waste Electrical and Electronic Equipment (WEEE) directive, which sets weight-based targets for recovery, preparation for re-use and recycling. The increasing strategic relevance of the supply of raw materials has, however, spurred a more integrated approach towards resource efficiency. In addition to the prevention of disposal, recycling practices are now also meant to contribute to sustainable materials management by pursuing (i) a higher degree of material cycle closure, (ii) an improved recovery of strategically relevant materials, and (iii) the avoidance of environmental burdens associated with the extraction and refining of primary raw materials. In response to this evolution, this paper reports about the development of an indicator set that allows to quantitatively demonstrate these recycling benefits, hence going further than the weight-based objectives employed in the WEEE directive. The indicators can be calculated for WEEE recycling processes for which information is available on both input and output fractions. It offers a comprehensive framework that aims to support decision making processes on product design, to identify opportunities for the optimization of WEEE End-of-Life scenarios, and to assess the achieved (or expected) results of implemented (or planned) recycling optimization strategies. The paper is illustrated by a case study on the recycling of LCD televisions.vol. 8

Annually 2.7 million tonnes of plastics containing Flame Retardants (FRs) are globally discarded in Waste Electrical and Electronic Equipment (WEEE). Little is known on the feasibility of closing material loops for FR plastics. Therefore, series of experiments were set up to analyze the feasibility of separating plastics containing FRs from one specific product category, namely End-of-Life (EoL) Liquid Crystal Display (LCD) TVs. The characterization of the housings of this waste stream indicated a concentration of 18 wt% Bromine based (Br) FRs and 31 wt% Phosphor based (P) FRs, the remainder not containing FRs. With practical tests it was demonstrated that, after disassembly and plastic identification, the co-polymer poly-carbonate (PC)/acrylonitrile-butadiene-styrene (ABS) containing PFR can be recycled in a closed loop system. Based on the determined plastic density distributions and separation efficiencies of optical sorters, a purity of 82% was calculated for PFR PC/ABS separated from EoL LCD TVs after size-reduction (shredding). Performed miscibility tests indicated that for this fraction at least a factor 10 dilution with virgin material is required. In addition, higher waste volumes are required for a size-reduction based treatment to become economically viable and technical challenges still need to be faced, whereas closed loop recycling of PFR PC/ABS from the current waste stream of EoL LCD TVs of different brands in a disassembly based treatment is found to be technically feasible and economically viable under European boundary conditions.vol. 8

Repair practices are driven not only by consumers’ internal motivation, but also by external infrastructural, social including cultural, financial, and political factors. We explore these factors with the goal of understanding the public repair of electrical and electronic products (e‐products) from a systems perspective to help devise appropriate change interventions. We document (a) behavioral aspects, (b) techno‐economic factors, and (c) intervention strategies aimed at promoting repair practices. To gauge this, a survey was administered among 922 volunteers across 14 countries with experience in repairing e‐products at public repair events. Findings suggest that while behavioral constructs including personal values, beliefs, and attitudes toward product repair are the main proximal drivers of intention to repair, the ability to repair plays an important role. Further, these individual factors are influenced by the techno‐economic settings such as access to repair services, economic benefits, and the ease of product repair stands out as the key enablers for product lifetime extension. As per intervention strategies, the results highlight economic incentives, regulatory requirements, and public awareness as the key drivers. However, influencing repair behavior directly may not always be the most effective strategy. New initiatives to improve involvement should focus on more repairable products, exploiting the innovative potentials of commercial as well as non‐profit repair initiatives, education, and supporting the development of skills among volunteer repairers.
