The generation and management of municipal solid waste (MSW) are important components for city development, both of which are spatiotemporally heterogeneous among these metropolitans, as a result of diverse socioeconomic statuses. This study attempts to sufficiently reveal the spatiotemporal heterogeneity by determining the MSW per capita, MSW composition, and proportion of each management strategy (landfilling, incineration, and compositing). Singapore is taken for comparison, for it is a Chinese community and well-known for its outstanding performance in environmental sanitation. Results show that MSW per capita is highly dependent on GDP per capita, and exerts an increasing tendency with time, but can be relieved with MSW reduction policy. For each metropolitan, the development of landfilling and incineration fits the Kuznets curve well, and government policy is a more determinant factor than GDP. MSW composition is also time- and location-dependent, and source sorting generally favors the subsequent resource utilization including the mainstream incineration. In addition to MSW generation and management, the action, goal, and experience in Singapore are expatiated, which are believed to be of referential significance for these metropolitans.</p></div>","PeriodicalId":100245,"journal":{"name":"Circular Economy","volume":"2 2","pages":"Article 100041"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50183928","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 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}

In this work, we proposed a methodology, integrating material flow analysis, life cycle analysis, and scenario analysis for analyzing plastic footprint (incl., material and environmental footprint) at enterprise level and from the perspective of supply chain. A clothing enterprise was chosen as the studied case, and three pathways of plastic reduction were analyzed, incl., reducing unnecessary plastic packaging, using alternative materials, and using recycled materials. The indexes of the plastic footprint of the case enterprise were obtained. In 2019, the weight of plastic packaging used by the case enterprise was 1,949.10 t. 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}
