Clean production refers to the continuous implementation of measures—such as improving design, utilizing clean energy and raw materials, adopting advanced process technologies and equipment, enhancing management practices, and promoting comprehensive resource utilization—to reduce pollution at its source, improve resource utilization efficiency, and minimize or prevent the generation and discharge of pollutants during the production, service, and product usage stages, thereby mitigating or eliminating hazards to human health and the environment. Clean production represents a win-win strategy that balances corporate development with the protection of environmental resources; it has become a prevailing management technology trend among industrial enterprises worldwide for pollution control. Furthermore, it facilitates the transition of industrial pollution prevention and control from a "end-of-pipe" approach to a "source control" approach—namely, minimizing raw material and energy consumption, reducing pollutant emissions to the lowest possible level, alleviating the burden of external treatment facilities, and lowering pollution control costs.
