With the rapid and prosperous development of China's express delivery industry, the environmental issue of packaging waste has become increasingly pressing. Express packaging is diversified and complicated, with obstacles of excessive packaging and low recycling rate, which pose challenges to the low-carbon development of the express industry. At present, the amount and flow of express packaging waste are indistinct, and a systematic assessment of environmental emissions is lacking. In this study, the amount of express packaging waste generated is assessed, the measurement model is constructed through field research, and the overall material metabolism pattern is analyzed using material flow analysis (MFA). Further, life cycle assessment (LCA) is adopted to assess the environmental impact of treating 1 ton of express packaging waste and its potential for pollution and carbon reduction. The findings reveal that China generated 16.11 million tons of express packaging waste in 2023, predominantly paper and plastic. The comprehensive utilization rates of paper and plastic express packaging waste are 50.1% and 13.2%, respectively. Most plastic packaging is mixed in municipal waste to be landfilled or incinerated. Treatment of 1 ton of express packaging waste generates 796 kg CO eq. of greenhouse gas emissions. The reuse, recycling, and incineration result in avoided environmental burdens. By 2030, source reduction, increasing the proportion of incineration and recycling, and promoting recycled packaging could diminish most environmental impacts by 10% to 40% and synergistically reduce CO and pollutants such as PM and heavy metals. This study systematically explores the environmental problems of express packaging waste in China. It can provide data support and policy recommendations for the long-term green development of the express industry.
