Although consumer demand for longer lasting products that can be easily repaired has been on the rise, it is not certain that consumers are fully able to identify such products and willing to pay a premium for them. France introduced a mandatory product repairability index in 2021 and plans to introduce a mandatory product durability index by 2024. The reasoning was to allow consumers to benchmark products, and to provide incentives for manufacturers to design durable and repairable products. This initiative would most likely speed up activities for developing a harmonised European Union (EU) labelling scheme to avoid the possibility that various EU countries start their own schemes, which could be problematic for business within the EU single market. However, there is uncertainty regarding how to best display a durability label for influencing consumer choice. This contribution reviews the literature on product durability information and labelling, addressing consumer perceptions on durability labelling and whetherthe provision of durability information is taken into account in purchasing decisions. Potential implications in durability labelling implementation are discussed, concluding the article with suggestions for overcoming potential implementation challenges.","PeriodicalId":100245,"journal":{"name":"Circular Economy","volume":"34 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75202028","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By employing profit and sensitivity analyses, we found that resource-recovery companies (Rs) are the key for recycling, echelon utilization, and recovery mechanism. For R, the high resale price of waste LiNixMnyCo1−x−yO2 batteries was not conducive to recovering waste batteries. However, the recycling behavior of R was beneficial for resisting the risk of high resale price of waste LiNixMnyCo1−x−yO2 batteries. This condition increased the profits by saving on the buying cost and reselling of WPBs to echelon-utilization companies. Following the decrease in the number of recyclers in the recycling system, the profits of R also increased. However, when the proportion of recycled waste LiNixMnyCo1−x−yO2 batteries was 100%, the profits of R faced risks due to the high resale price of waste LiNixMnyCo1−x−yO2 batteries. For other recyclers, only the power-battery manufacturers (Ms) were willing to reduce the resale price of waste LiNixMnyCo1−x−yO2 batteries to let R earn profit because R supplied regenerated materials to M at a lower price than the material companies.

The recycling of LIBs is key to the sustainable development of the new energy industry, which is consistent with the concept of circular economy as well. And the green extraction of critical metals is the core part of the development. As an alternative to traditional pyrometallurgy and hydrometallurgy, emerging mechanochemical technology provides a new approach for high efficiency and green recycling of critical metals from spent LIBs, as it has the advantages of easy operation, flexibility, and short processing time. This article reviews the state of the art of mechanochemical technology in the recycling of critical metals from spent LIBs. Based on numerous practices, a framework including mechanochemical activation, organic reaction, inorganic reaction, redox reaction, gas-solid reaction, and solid-phase synthesis was constructed. These practices have proved that mechanochemical technology can provide a greener and more sustainable solution for recycling critical metals from spent LIBs. The metals can be transformed into high-value metal products at room temperature and under ordinary pressure, leading to efficient recycling of critical metals and significant reduction of wastes.</div>","PeriodicalId":100245,"journal":{"name":"Circular Economy","volume":"1 2","pages":"Article 100012"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2773167722000127/pdfft?md5=fc08b02d731397588349629e7ae1e226&pid=1-s2.0-S2773167722000127-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82808464","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the adverse impacts of electronic waste (e-waste) disproportionately affect low-income communities and marginalized ecosystems in nations with economies in transition. The embodied carbon footprint of new electronic products, especially information and communications technology (ICT) devices, is an important source of greenhouse gas (GHG) emissions, accounting for 67% ± 15% of total lifetime emissions, instigated by mineral mining, manufacturing, and supply chain transportation. We estimate that between 2014 and 2020, embodied GHG emissions from selected e-waste generated from ICT devices increased by 53%, with 580 million metric tons (MMT) of CO2e emitted in 2020. Without specific interventions, emissions from this source will increase to ∼852 MMT of CO2e annually by 2030. Increasing the useful lifespan expectancy of electronic devices by 50%–100% can mitigate up to half of the total GHG emissions. Such outcomes will require coordination of eco-design and source reduction, repair, refurbishment, and reuse.

However, in the field of metal resource recycling, there is still a lack of intelligent and accurate recognition of metallic products, which seriously hinders the operation of the metal resource recycling industry chain. In this article, a convolutional neural network with dual attention mechanism and multi-branch residual blocks is proposed to realize the recognition of metallic products with a high accuracy. First, a channel-spatial dual attention mechanism is introduced to enhance the model sensitivity on key features. The model can focus on key features even when extracting features of metallic products with too much confusing information. Second, a deep convolutional network with multi-branch residual blocks as the backbone while embedding a dual-attention mechanism module is designed to satisfy deeper and more effective feature extraction for metallic products with complex characteristic features. To evaluate the proposed model, a waste electrical and electronic equipment (WEEE) dataset containing 9266 images in 18 categories and a waste household metal appliance (WHMA) dataset containing 11,757 images in 23 categories are built. The experimental results show that the accuracy reaches 94.31% and 95.88% in WEEE and WHMA, respectively, achieving high accuracy and high quality recycling.</div>","PeriodicalId":100245,"journal":{"name":"Circular Economy","volume":"1 2","pages":"Article 100014"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2773167722000140/pdfft?md5=13a787cc567184762ed8c2089983fa84&pid=1-s2.0-S2773167722000140-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77539343","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
