Summary: The consumption of electric and electronic equipment (EEE) in developing countries has reached alarming levels, leading to the generation of massive amounts of electronic waste (e-waste). A diagnosis of e-waste proliferation in Rwanda is necessary to establish a sustainable management plan. The Rwandan national plans prioritize the use of information communication and technology (ICT) tools, considering ICT as an essential driver for a knowledge-based economy and development. However, outdated EEE is being dumped as e-waste in large quantities and at an increasing rate in Rwanda, often disposed together with other household waste. Consequently, proper e-waste management strategies including sorting/separation, repairs, reuse, recycling, remanufacturing, and disposal have been proposed to address this growing threat and safeguard the environment and human health.

Summary: Waste electrical and electronic equipment (WEEE) is an inevitable waste in modern society, containing valuable and harmful materials. China has established a WEEE management system to address pollution issues. Importers and manufacturers of electrical and electronic equipment (EEE) pay treatment fees to facilitate recycling. In 2020, 45 million sets of WEEE were certified for recycling, with TVs, refrigerators, washing machines, computers, and air conditioners being the main items. Spatial analysis shows that recycling activities are concentrated in the mid-east and east regions of China.

Summary: This study examined the preferences and behaviors of residents in Putrajaya, Malaysia, regarding the management of electrical and electronic equipment waste (WEEE). The survey showed that 80% of respondents had good knowledge of WEEE management and 75% said they would recycle their WEEE. However, only 44% said they would separate it from other household wastes. Additionally, 88% of households were willing to pay a collection fee for WEEE. The study suggests that Extended Producer Responsibility (EPR) mechanisms and awareness campaigns can improve WEEE management.

Summary: Remanufacturing is a sustainable product recovery strategy with environmental, economic, and social benefits. However, there is a lack of comprehensive review of decision factors and how they fulfill the requirements of different stakeholders in remanufacturing systems. Future research should focus on bridging the gap between consumers and other stakeholders in the remanufacturability decision-making process.

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.
