What is the concept of cleaner production?

So far, there is no unified definition of cleaner production. Generally speaking, cleaner production belongs to a production mode, which denies the traditional linear production mode. 65438-0989 The Center for Industry and Environment of the United Nations Environment Programme has formulated a cleaner production plan to promote cleaner production worldwide. According to the definition of UNEP, cleaner production refers to the continuous application of comprehensive preventive environmental strategies in production processes and products to reduce the risks to human beings and the environment.

1in may, 1992, China held the first international cleaner production seminar and issued the China cleaner production action plan (draft), which marked the opening of cleaner production practice in China. On June 29th, 2002, the 28th meeting of the Standing Committee of the Ninth NPC in People's Republic of China (PRC) passed the Law on the Promotion of Cleaner Production in People's Republic of China (PRC), which established the policy framework and implementation requirements of cleaner production in China. In the "People's Republic of China (PRC) Cleaner Production Promotion Law" promulgated and implemented in 2003, combined with China's actual and international practices, cleaner production is scientifically defined: cleaner production refers to measures such as continuously improving design, adopting advanced technologies, equipment, using clean raw materials and energy, improving management and comprehensive utilization, controlling and reducing pollution from the source, improving the utilization efficiency of resources as much as possible, and reducing or avoiding the production of products. 20 12 On February 29th, the 25th meeting of the 11th NPC Standing Committee of People's Republic of China (PRC) passed the NPC Standing Committee's Revision

The essence of cleaner production is to plan and manage human production activities with the least resource and energy consumption. It reduces, recycles and harmlessly wastes or consumes them in the production process. Cleaner production technology to control the generation of waste from the source is a positive governance concept, which is not only a comprehensive embodiment of technical feasibility and economic profitability, but also fully embodies the dual significance of developing circular economy in environmental and development issues. Before the concept of cleaner production was put forward, the industrial development model experienced the process of direct discharge, dilution discharge and terminal treatment of factory waste. The schematic diagram of cleaner production development mode is shown in Figure 6. 13.
