Summary: Modular connectors containing gold and copper are used by computer users. A method to selectively remove trace amounts of gold(III) from hydrochloric acid solutions using sorbents is presented. Gold(III) ions were effectively recovered from the digested modular connector using Purolite MN 202. The highest sorption capacity of gold(III) ions was obtained using Purolite MN 202 after impregnation with Cyanex 272.

Summary: E-waste is a rapidly growing waste stream that contains both hazardous components and valuable resources. Developing countries face challenges in managing e-waste due to lack of infrastructure and reliance on informal sector. There is an urgent need to design better framework for e-waste management and help these countries improve recycling and disposal facilities.

Summary: In order to address the increasing issue of e-waste, understanding consumer behavior is crucial for implementing a circular economy. Current research primarily focuses on consumer disposal and recycling behaviors, with less attention on reuse and repair behaviors. Future research could emphasize developing a more consumer-centric model for managing e-waste within the circular economy framework.

Summary: Recently, there has been significant interest in the material flow analysis (MFA) of waste from electrical and electronic equipment (WEEE) as a decision-making tool for sustainable WEEE management. However, there is a lack of review studies on the development of MFA in WEEE management. In this study, 115 MFA studies published between 2010 and 2022 were analyzed to provide an overview of research progress and recommendations for future studies. The analysis revealed an increase in MFA studies in major OECD nations, but limited research in concentrated areas of WEEE, particularly in non-OECD countries. Furthermore, there is a lack of studies addressing uncertainty analysis, circular economy, and life cycle analysis in MFA research.

Summary: It is common to see competition between the formal and informal sectors in the waste electrical and electronic equipment (WEEE) recycling markets in developing countries. This study explores the competitive strategies of the two sectors, focusing on price and service. The impact of subsidies on the formal sector's decisions is also examined. Results show that subsidies can encourage the formal sector to invest in better collection service.

Summary: This study analysed the generation characteristics of industrial hazardous waste in South Korea from 2008 to 2018 and found that factors such as industrial output and characteristics of hazardous waste generation-to-energy are major driving factors influencing the increase of industrial hazardous waste generation. Meanwhile, industrial structure and energy efficiency affect the decrease of industrial hazardous waste generation in most industries. It was also confirmed that different industries have varying driving factors affecting industrial hazardous waste generation. These results provide insights for the South Korean government to improve and customize hazardous waste management policies.

Summary: This study presents a framework that systematically identifies the drivers of urban metabolism and critically engages with them for the development of transformative future visions. The framework categorizes the drivers into seven thematic categories (demographic, economic, cultural, political, technological, environmental, and infrastructural) and includes an eighth category (power) to examine the interactions between drivers, activities, and flows in the city. Applying this framework to a case study of biowaste management in Rennes, France, revealed its usefulness in identifying overlooked drivers. This proposed framework can become a useful tool for solution-oriented urban metabolism research.

Summary: This study examines the economic and environmental effects of transitioning towards more circular food systems in the European Union (EU27) by feeding animals with low-opportunity-cost feed and better utilizing local feed resources. The results show that providing subsidies for circularity and promoting the use of low-cost feed can increase animal production, but also have negative impacts on land use and emissions. On the other hand, promoting domestic feed sourcing through import tariffs can decrease animal production and greenhouse gas emissions in agriculture. However, complementary policies are needed to mitigate drawbacks and enhance benefits of a more circular agri-food system.
