The principle of EPR is the key to the sustainable development of waste electrical and electronic equipment (WEEE) recycling. The implementation of the recycling fund system has been facing major problems. This article proposes a plan on refining the producer's recycling target to improve the current fund system in China. With the aim to maximize the amount of WEEE recycling, minimize the overall producer's recycling cost, and providing the best supports to the recycling industry, a multi-objective decision-making model is constructed to identify the optimum producer's recycling target for WEEE. Data from the recycling fund system and EPR pilot project of the Ministry of Industry and Information Technology are used to test the model. The results show that, under the condition that the amount of recycling is equal to the current level, the levy of recycling fund can be reduced by 20%, which can effectively drive the producers to take more responsibility in the collection and recycling of their end-of-life products. The multi-objective decision-making model for producer's recycling target provides a basis for the adjustment of China's WEEE recycling fund system policy, which will alleviate the challenge at present, and involve more producers to devote in collection systems. It also shows the alternative solution for EPR in non-fund business models in the recycling industry.</p></div>","PeriodicalId":100245,"journal":{"name":"Circular Economy","volume":"2 2","pages":"Article 100038"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50183929","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}

The average weight of plastic packaging used for each garment was 19.67 g. The weight of plastic packaging consumed per 10,000 USD of revenue was 0.25 kg. It was found that promoting lightweight plastic materials in supply chain (∼14% reduction in thickness of plastic packaging bags), reducing unnecessary plastic use within the enterprise, increasing the number of plastic packaging cycles (∼50% reused), and using recycled plastic materials (∼15%) are effective ways for enterprises to achieve environmental benefits.</p></div>","PeriodicalId":100245,"journal":{"name":"Circular Economy","volume":"2 2","pages":"Article 100037"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50183831","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}

Historically, the onus for coordinating recycling programs has fallen onto taxpayers and governments, which requires significant capital financing and labour for solid waste management. Large volumes of packaging and printed paper (PPP) materials in the marketplace has municipalities, including in the Atlantic Canadian province of Nova Scotia, shouldering the burden of residential recycling programs that are increasingly costly to the administer. A waste management approach known as the extended producer responsibility (EPR) principle leverages financial resources of producers to fund the recycling of their products. Several EPR for PPP programs already exist across Canada, and efforts are underway by local governments across Nova Scotia to pursue EPR for PPP. This research examined potential impacts of EPR for PPP on Nova Scotia's business community, comprised of many small enterprises. Through a combination of literature review, classification of national steward data, and analysis of provincial business data, findings show that a small subset of industries are most impacted by EPR for PPP across Canada, and higher grossing businesses are required to fund EPR for PPP, and less so small, local enterprises. Analysis revealed that only 8.3% of all businesses operating within Nova Scotia would likely become obligated stewards in the province's proposed program. Lastly, recommendations are proposed to both reduce detrimental impacts on provincial businesses, and to gain the maximal benefits of EPR for PPP for improved recycling systems. Recommendations focussed on fair exemption conditions appropriate to the local region, harmonization of EPR for PPP across Atlantic Canada, developing material specific fees, and investments in local recycling end-markets.</p></div>","PeriodicalId":100245,"journal":{"name":"Circular Economy","volume":"2 2","pages":"Article 100039"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50183828","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}

Meanwhile, the low-carbon transition has become a critical incentive for producers to seize the opportunities in carbon emission reduction through the closed-loop supply chain. This study reviews the carbon emission information disclosed by automobile manufacturers in their open reports on sustainability to identify the strategic links between circularity and low-carbon transition from the perspective of producers.

At present, residents in many low-income areas are still illegally and unscientifically disposing of e-waste to profit from it. The toxic and harmful substances produced affect the global ecological environment through the geochemical cycle. In this review, we provide a systematic overview of the status quo of e-waste recycling globally. E-waste is placed into a framework, grouped by product type, quantity, composition, environmental health risk, and global impact. Management measures, legislative policies, current disposal, and transboundary movement are summarized at international, regional, and national levels, illustrating the status and challenges of e-waste collection and disposal. Techniques such as physical dismantling, component recycling, metal extraction, and re-utilization of non-metallic materials are described, which can have long-term impact on the ecosystem.
