Abstract

Magnesium is widely used in the automotive sector and many other end-use sectors. However, virgin magnesium resource is limited and its production generates significant environmental pressures. Magnesium recycling can effectively reduce the consumption of virgin magnesium resources and corresponding environmental impacts. By combining both stock-driven and inflow-driven models and both Weilbull and normal lifespan distribution functions, this study aims to estimate the recycling potential of magnesium and its corresponding environmental impacts in China, probably the largest magnesium producer and exporter, for the period of 2022–2050. Results show that the annual magnesium recycling potential is more than four million tons (Mt), indicating that such secondary magnesium supply could mitigate the overall consumption of virgin magnesium resource in China. This recycling effort can also reduce more than three Mt. of CO₂ emission. Finally, considering China's realities, three policy recommendations are proposed.

期刊介绍： Environmental Impact Assessment Review is an interdisciplinary journal that serves a global audience of practitioners, policymakers, and academics involved in assessing the environmental impact of policies, projects, processes, and products. The journal focuses on innovative theory and practice in environmental impact assessment (EIA). Papers are expected to present innovative ideas, be topical, and coherent. The journal emphasizes concepts, methods, techniques, approaches, and systems related to EIA theory and practice.
