Environmental benefit of recycling plastics from waste electrical & electronic equipment
Plastic recycling from waste electrical and electronic equipment (WEEE) can effectively deal with both the resource crisis and environmental pollution. However, the life cycle environmental impacts of recycling plastics derived from WEEE are still unclear. Therefore, this study adopts life cycle assessment and machine learning methods to estimate the environmental impacts and mitigation potentials of WEEE plastics recycling. We find the environmental degradation of WEEE waste plastics recycling are mainly from electricity consumption and transportation during the disassembly and granulation stages. Significant variation in the reduction effect of WEEE plastics recycling technologies is observed, ranging from 13 % to 77 %. The WEEE generation is projected to exhibit an S-shaped trend from 103 tonnes in 1980 to 15.42 million tonnes (Mt) in 2050, contributing to 10.33 Mt of carbon reduction. Improving the efficiency of WEEE plastics recycling technologies and enhancing legal recycling of waste air conditioner can efficiently reduce environmental emissions.
期刊介绍:
The journal Resources, Conservation & Recycling welcomes contributions from research, which consider sustainable management and conservation of resources. The journal prioritizes understanding the transformation processes crucial for transitioning toward more sustainable production and consumption systems. It highlights technological, economic, institutional, and policy aspects related to specific resource management practices such as conservation, recycling, and resource substitution, as well as broader strategies like improving resource productivity and restructuring production and consumption patterns.
Contributions may address regional, national, or international scales and can range from individual resources or technologies to entire sectors or systems. Authors are encouraged to explore scientific and methodological issues alongside practical, environmental, and economic implications. However, manuscripts focusing solely on laboratory experiments without discussing their broader implications will not be considered for publication in the journal.
