“…In 2011, China Household Electric Appliance Research Institute (CHEARI) and NDRC assessed and developed the application of the Chinese 'WEEE Catalog', for instance, laptops, televisions, refrigerators, air conditioners, etc. After considering environmental, economic, and social perspectives, CHEARI built up a review to ensure the Chinese e-waste management is on the right track by providing the government with promptly information and advanced technological support [17]. In May 2020, NDRC enacted the "Implementation Plan on Improving the Recycling and Processing System of Waste Home Appliances and Promoting the Renewal and Consumption of Household Appliances" with seven other departments.…”

As one of the major waste streams towards the global environment, waste electrical and electronic equipment (WEEE), also called e-waste, is a huge problem needed to solve. Different countries are using various types of strategies and management to ensure the WEEE is limited to the minimum effect on the environment. Using China and the United States as the typical countries to disclose the action different countries have taken towards the management of e-waste. The legislations of e-waste policies are implemented in many countries which the major e-waste produced countries are considered in this paper to form the comparison between those countries. Most countries in Europe are showing more attention towards the management of WEEE and countries such as India or Brazil are less focused on the recycling of WEEE. The major e-waste produced countries tend to have more moderate management to balance the economy and the environment.

“…The subsidies have created unexpected niches for emergence and development of Internet-based e-waste collection business . In May 2020, the Implementation Plan on Improving the Recycling and Treatment System of Waste Home Appliances and Promoting the Renewal of Household Appliances Consumption was enacted to improve the recycling and processing system of disposed household appliances through “Internet +” for recycling of e-waste. , …”

“…The operating rate is defined as the ratio of the operating recycling plants to the total number of possible operating factories at any time (). Due to the ongoing impact of COVID-19, the subsidy delay has reduced the number of formal e-waste treatment enterprises . Apparently, subsidies are only a temporary supporting mechanism for many formal dismantling enterprises.…”

E-waste recycling has been a hot topic around the world. This Feature revisits the issues raised by our previous Feature 10 years ago, i.e., the environmental, economic, and social benefits of e-waste recycling, using China as an example. The decadal journey of e-waste recycling has witnessed a giant leap from haphazard disposal initially to regulated disassembly presently. Specific successful stories include cleaned environment and reduced human exposure, significant advantages of urban mining over mineral mining, additional employment opportunities, and improved legislation system related to e-waste recycling. Strict legislation systems related to e-waste management based on the principle of Extended Producer Responsibility are key to the sustainable development of the e-waste recycling sector in China. The experiences and lessons learned in China would provide valuable guidelines for other developing countries.

“…In this way, the grey system theory provides a useful tool for dealing with problems that cannot be modeled using traditional mathematical methods. By incorporating both known and unknown information into the analysis, grey system theory can help researchers and practitioners make more informed decisions in complex and uncertain environments [16].…”

Under uncertain conditions, stronger supply chain resilience can effectively reduce disruption risks and help enterprises achieve their goal of high-quality operations. This paper constructs a resilience evaluation index system for manufacturing enterprises from the perspective of the supply chain and uses the improved TOPSIS method to quantify the level of resilience. Taking into account that the resilience index is easily affected by nonconventional factors in the real environment, the WAWBO weakening buffer operator and the metabolism idea are introduced to improve the grey prediction method, so as to realize the dynamic prediction of the resilience index. In addition, a supply chain resilience early warning model is constructed by combining it with the quantification method of resilience. Using the data of a Chinese electronics manufacturing enterprise as a case study, the results demonstrate the effectiveness of the proposed resilience quantification method, and the improved grey prediction method has higher prediction accuracy. The study provides a new idea for relevant enterprises to improve the early warning ability of their supply chain, thus promoting the sustainable development of the supply chain.
