Abstract
This study estimates the recycling potential of large-scale public transport vehicles (LPTV) in China, predicting the end-of-life quantity of railway and aviation equipment from 2000 to 2050. The total obsolescence mass in 2020 exceeded 33 million tons and is expected to reach 74 million tons by 2050. By 2050, waste LPTV will contain significant amounts of steel, aluminum, titanium, and neodymium. The study compares waste LPTV to e-waste and end-of-life private vehicles, revealing a distinct industry succession. Recycling potential and economic benefits are assessed, offering guidance for policy formulation.
