Core Insights - The Ministry of Industry and Information Technology reported that China's mobile phone production reached 961 million units in the first eight months of this year, with 758 million of those being smartphones, reflecting a year-on-year growth of 1% [1] Group 1: Mobile Phone Recycling Process - In an automated operation center in Dongguan, old mobile phones are processed along a 100-meter long automated production line, where each phone is assigned a unique QR code for tracking [3] - The phones undergo an X-ray inspection to assess internal components without disassembly, completing the process in just 7 seconds [5] - A 360-degree photo booth captures 22 images of each phone, which are analyzed by a self-developed quality inspection model, achieving a precision of 24 microns and an accuracy rate of over 99.5% [7] - The "function diagnosis" area tests over 70 indicators, including camera functionality, microphone performance, battery health, and charging speed, creating a comprehensive "health record" for each device [11] Group 2: Economic and Environmental Impact - The automation in the recycling process has reduced the comprehensive quality inspection cost per phone by 30% and cut labor assistance costs by 80% [13] - China generates over 400 million waste mobile phones annually, and improper disposal can lead to resource wastage and electronic pollution. The new standardized detection and grading process not only recovers real value but also supports a billion-level second-hand market [15] - This process exemplifies a closed-loop system of "recycling-detection-grading-reuse," benefiting companies through cost savings and profit generation, while providing consumers with reliable second-hand options and promoting environmental sustainability [15]
