This study aims to explore the economic recycling methods of oily metal shavings in automobile engine factories. By comparing physical, chemical, biological, and comprehensive treatment technologies, the performance of various methods in treatment efficiency, resource recovery rate, and energy consumption was evaluated. The results showed that the highest treatment efficiency of the comprehensive treatment technology could reach 89%; resource recovery rate could reach 41%; resource consumption could reach only 0.68 kilograms of standard coal. The research methods include designing a multi-stage processing flow, optimizing process parameters, and verifying the actual effects of various technologies through experiments. The conclusion indicated that comprehensive treatment technology achieved the highest resource recovery rate while minimizing energy consumption, demonstrating the best economic and environmental benefits. This study provided an efficient and environmentally friendly solution for the reuse of oily metal shavings in automotive engine factories, which is of great significance for promoting the resource utilization of industrial waste.
