Summary: In order to improve the low e-waste recycling rate, the Chinese government has implemented a series of intervention measures. However, the effectiveness of these measures is controversial. This study constructs a system dynamics model to investigate the impact of Chinese government intervention measures on e-waste recycling from a holistic perspective. The findings suggest that the current intervention measures do not effectively promote e-waste recycling. The most effective adjustment strategy is to increase government policy support while strengthening punishments for recyclers.

Summary: This study explores the characteristics of microplastics and complex pollutions in a formal e-waste recycling base in Shanghai, China. It found that microplastics show weak adsorption effect for heavy metals, but act as an important carrier of n-aryl octa-brominated diphenyl ethers (8PBDEs). The study provides a theoretical basis for understanding the potential pollution of microplastics and upgrading control measures.

Summary: Research shows that electronic waste is highly toxic and has a rapid growth rate, emphasizing the need for more studies on environmentally friendly waste disposal. China, the USA, and India are the countries with the highest publication rate on this topic, whereas Brazil has a relatively low research output in this field.

Summary: The study measures and predicts the monitoring of Chinese e-waste, including sources, flows, scrap, and recycling potentials of electronic products, based on data from the government and 109 formal e-waste recycling enterprises. Currently, e-waste recycling is gradually becoming the official waste disposal approach, but the industry has problems such as lower recycling efficiency and scale, lack of advanced technologies, and corresponding laws and regulations. The collected and analyzed data shed light on the e-waste market size in China, and suggestions for optimizing the e-waste recycling industry through legal, reasonable, and efficient methods are put forward.

Summary: Rapid advances in electronics and telecommunications technologies have resulted in a significant increase in e-waste, with India producing over 3.23 million tonnes of e-waste each year. The informal waste management sector, specifically the kabadiwalas in India, plays a crucial role in processing the majority of e-waste generated in the country. A case study found that approximately 45% of respondents prefer to dispose of their e-waste to kabadiwalas. GPS tracking showed that these waste collectors travel long distances using manual and modified three-wheeler vehicles to collect household waste, including approximately 10% e-waste. Integrating kabadiwalas into the formal e-waste industry could improve e-waste management and value recovery operations in India.

Summary: The study found that the mass concentration of PM10 was higher but the number concentration was lower in the manual dismantling workshop compared to the thermal dismantling workshop. The gaseous phase PBDE concentration was higher in the manual dismantling workshop while the particulate phase PBDE concentration was higher in the thermal dismantling workshop. The size distribution of particles was similar between the two workshops, but there were significant differences in the distribution of particle-bound PBDE.

Summary: From the perspective of actor-network theory, this study explores how e-waste online recycling platforms establish their business ecosystems through symbiotic strategies. A comparative research is conducted based on two typical platforms in China. The findings indicate that translation plays a crucial role in promoting the construction of these ecosystems. The different strategies require different translation approaches, leading to the formation of embedded and central business ecosystems.

Summary: The study on waste management in the textile supply chain in China reveals the challenges including diverse types of waste, low recycling rates, long payback periods for investments, and lack of technical support. Despite exhibiting more sufficient waste management compared to other countries, China still has potential for improvement in waste management practices.

Summary: This paper investigates the impact of European Union regulations on e-waste exports. The findings suggest that taxation is ineffective in reducing e-waste exports and may even increase them. Additionally, high dependence on foreign raw materials and sub-standard waste collection systems contribute to the increase in e-waste exports. Therefore, investing in e-waste collection facilities can better utilize the valuable resources in this waste.

Summary: The study aims to develop a decision-support framework to help plan on-site and off-site construction waste recycling, using qualitative research methods in Shenzhen, China. Project characteristics and industrial and governmental supports are found to determine the technical and economic viability of a particular recycling option. These factors interact with each other and evolve over time and context to effect.

Summary: China will face challenges in dealing with PV waste in the future decades. This study comprehensively assesses and compares the costs and benefits of mechanical recycling, chemical recycling, and thermal recycling for PV waste using a life cycle assessment. The results show that all three technologies have superior environmental and economic performance compared with landfilling. Scenario analysis suggests that technological improvements, scaling up recycling, reducing transport distances, and subsidization can enhance the total benefits of PV waste recycling.

Summary: This study explores the potential of Surface e-precipitation (SEP) in recovering valuable elements and removing toxic elements from mining water of a polysulfide ore origin. The results show that SEP, combined with electrodeposition, can concentrate valuable metals by an order of magnitude at highly competitive rate and energy consumption values, and the recovery and relative content of the concentrated metals can be controlled. The comparison with other techniques reveals that SEP has higher selectivity but lower recovery.

Summary: With the increasing amount of household waste in China, improving the recovery rate of household recyclable waste is crucial for a sustainable and green future. This study proposes an improved pay as a site throws policy and considers the implementation of reward and reward-penalty policies to increase its feasibility. The results demonstrate that these policies effectively promote waste classification and HRW recovery.
