Environmental degradation, asymmetry and inequality in the recovery conditions from the COVID-19 pandemic, which have been particularly aggravated over the last three years (2019–2022), as well as the energy crisis in the Eurozone raise significant challenges for social cohesion and CE policies. This analysis aims to examine whether a change in the structure of the energy markets, densely populated areas, environmental performance, institutional quality, social protection and innovation affect the CE. The results reveal that circular activity is robustly and positively affected by factors such as institutional quality, resource productivity and entrepreneurship. As the level of social protection increases, the percentage of the population willing to adopt the CE principles increases, while EU countries consume more raw materials than they can actually recycle. An increase of 1% in the market share of the largest electricity production companies and the market share of companies supplying the largest volume of natural gas is linked to a reduction of 0.30% and 0.33%, respectively, in the circularity rate. This suggests that under imperfect competition in energy markets, there are signs of undermining the efforts of EU countries to collect waste for recovery.</p></div>","PeriodicalId":100245,"journal":{"name":"Circular Economy","volume":"2 3","pages":"Article 100048"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50194580","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 purpose of this paper is to design a bi-objective decision support tool for supply chain of composite material which combined with ABF and PET. Through the production, processing, recycling, and reprocessing of composite materials, the sustainable supply chain model of four different schemes is designed, and the data results of each scheme model are calculated and analysed. The tool can support supply chain modelling solutions that seek best practices for sustainable supply chains and optimize resource efficiency through cost and carbon dioxide emissions. The sustainable supply chain model was designed, created, and optimized in AnyLogic software using System Dynamics and Discrete Event Simulation modelling methods based on the supply chain model established by previous researchers. According to the analysis results of the model data, the reasonable design of the whole process can effectively reduce the cost and carbon dioxide emissions and achieve the effectiveness and implementation of the sustainable supply chain. The results of this study will provide reference for more sustainable supply chain models in the future. Further research on composite materials can be carried out by combining with practice.","PeriodicalId":100245,"journal":{"name":"Circular Economy","volume":"22 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78541489","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 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}

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}
