1, the principle of recycling, so that "waste" can be transformed into products to the maximum extent;
2, the principle of reduction, try to reduce resource consumption, pollution and emissions;
3, the principle of harmlessness, as far as possible to reduce the use of toxic and harmful raw materials and the generation and discharge of harmful pollutants;
4, the principle of reuse, the waste produced in the process of production and circulation, as a renewable resource fully recycled.
Extended data:
The significance of cleaner production:
Cleaner production audit refers to the process of investigating and diagnosing the production and service process according to certain procedures, finding out the causes of high energy consumption, high material consumption and heavy pollution, putting forward plans to reduce energy consumption, material consumption and waste generation, reducing the use, generation and resource utilization of toxic and harmful substances, and then selecting and implementing technically, economically and environmentally feasible cleaner production plans.
The core significance of cleaner production is the eight-character policy of "saving energy, reducing consumption, reducing pollution and increasing efficiency". The big aspect is to improve the utilization rate of resources, reduce the generation of pollutants from the source and promote sustainable development. From a small perspective, it is conducive to the upgrading of enterprises, reducing the waste of energy and raw and auxiliary materials, reducing costs, improving economic benefits and reducing the production of pollutants in the production process.
