“…As R1, design challenges were highlighted, and modifications were outlined by Hendrickson et al (2010) and Dzombak (2017) . Dzombak et al propose the Light As A Service (LaaS) model ( Dzombak et al, 2019 ). The shift to the LaaS modelretaining producer ownership -t r a c k s obsolete products in terms of failure and upgradeability and, at the same time, informs design that promotes reuse.…”

“…The replacement cycle represents the lengths of time a particular innovation functions before becoming obsolete and eventually replaced by a more efficient innovation. Dzombak et al (2019) and Liu and Keoleian (2020) addressed the effect of replacement on waste generation, with the possibility of early obsolescence of the whole product or a part. Reuter and Van Schaik (2015) discuss input characteristics as an important parameter that defines the recovery potential at the end.…”

“…However, this mismatch between environmentally optimal and economically optimal use provides more reuse, refurbish, and remanufacturing opportunity if a new business model can be innovated, such as LaaS. LaaS model -Lighting as a service -i s proposed by Dzombak et al (2019) , which works like PSS and may be helpful to realize R4/5 strategies.…”

“…Recovery can be planned at the preprocessing, product, component, and material levels. Reuse at the product level is quite relevant, particularly for the rapid innovation cycle, which leads to immature obsolescence of the still valuable lamps ( Dzombak et al, 2019 ;Rahman et al, 2019 ). Dzombak et al mentioned that over 60% of costs come from lighting at the municipal level, so continuous efficiency improvement can motivate wholesale replacement of the current system.…”

Recycling LED lamp technology requires a change from the traditional bulk material-based recovery process. Unlike preceding lighting technology, LED lamps cannot be recycled to meet the regulatory minimum recycling rate of 80% due to multi-materials, including small quantity precious metals, which reduce the sorting efficiency. Therefore, it is crucial to understand how the challenges have been approached in the scientific literature in this context. The review article investigates the circular solutions to the challenges that the end of life LED lamp management is facing. This review applies PRISMA systematic literature review to locate the relevant studies and investigate whether the proposed processes can increase the recycling rate, using the circular economy strategy as a theoretical framework. Several recycling processes have been proposed in the academic literature. However, the techniques have not been evaluated against the circular economy strategies to identify current gaps and possible ways. This review attempts to fill this gap by assessing the current approaches against the 10 R strategies (refuse, rethink, reconsider, reuse, repair, refurbish, remanufacture, repurpose, recycle and recover). The study suggests that recycling is the dominant strategy, but the higher R strategies such as reuse, repair, and remanufacture have also been discussed as potential life extension strategies. The study concludes by proposing an integrated treatment approach that focuses on higher R's (reuse, repair, refurbish, remanufacture and repurpose) instead of focusing on lower R's (e.g., recycling).
