Clean Production Audit Content: 5 types of objects (material consumption, energy consumption, water consumption, pollutants, toxic and harmful substances); 3 levels (concepts); 8 aspects (whole process); 7 stages (audit process); 8-character grand goal (energy saving, consumption reduction, pollution reduction, efficiency improvement). Clean Production Definition Interpretation: Thought essence: environmental strategy, innovative concept of development; basic characteristics: strategic, preventive, comprehensive, unified, sustainable; core elements: source reduction, pollution prevention, continuous application -- continuous improvement; applicable objects: production process, product, service; application requirements: for the production process — energy saving and consumption reduction, replacement and elimination, reduction of toxicity; for products — consider the entire life cycle; for service activities — incorporate environmental factors; tactics: environmental design, conservation, substitution, reuse, source reduction; purpose: improve ecological efficiency and reduce risks to humans and the environment. The emergence and development of clean production: 1. Environmental problems faced by humans: Environmental problems have developed from local and regional to global ecological crises, such as greenhouse effect (climate warming), acid rain, ozone layer depletion, increasing desertification, water resource scarcity, biodiversity reduction, toxic chemicals and hazardous wastes, marine and coastal pollution, forest destruction, energy resource shortage, etc., posing hidden dangers to human survival. 2. Regional environmental pollution issues: Before the mid-1980s (developed countries) 3. Global environmental pollution issues: (Since the mid-1980s) Acid rain, greenhouse effect, ozone layer depletion 4. Traditional environmental control measures: Pollution first, then treatment (end-of-pipe treatment); pollutants continuously increase: waste water — production waste water, domestic waste water; waste gas — industrial waste gas, process waste gas; solid waste — offcuts, packaging, office waste, domestic waste; noise — machinery and equipment noise, construction noise. 5. Traditional development patterns, characterized by massive resource consumption and extensive management, are increasingly陷入 resource shortages and environmental pollution, creating two major dilemmas: Firstly, traditional development models have caused great environmental damage and wasted a large number of resources, accelerating the exhaustion of natural resources and making development difficult to sustain; secondly, industrial pollution control policies dominated by end-of-pipe treatment neglect the control of the entire process of pollution and cannot fundamentally eliminate pollution. Clean production can effectively address these two issues and has the following significant advantages: a. Clean production can use energy-saving, consumption reduction, pollution reduction, and cost reduction to improve product quality, enhance the economic benefits of enterprises, and improve market competitiveness. On the other hand, it can greatly reduce the pollution load of end-of-pipe treatment, save a large amount of environmental protection investment (one-time investment and facility operation costs), and improve the enthusiasm and consciousness of enterprises in preventing and controlling pollution. b. Clean production can utilize resources and energy to the maximum extent through recycling or reuse, converting raw materials into products to the maximum extent, and eliminating pollution in the production process. By improving equipment or changing combustion methods, energy utilization can be further increased, reducing the generation and discharge of pollutants, saving resources and energy, and achieving significant economic benefits with less investment. c. Clean production can avoid and reduce secondary pollution caused by incomplete end-of-pipe treatment because it adopts a large number of source reduction measures, reducing the use of raw materials containing toxic components, improving the conversion rate of raw materials, reducing logistics loss and the generation and discharge of pollutants, thereby reducing the opportunity for secondary pollution. d. Clean production can replace toxic products, toxic raw materials, and energy to the maximum extent, replace processes and equipment with large amounts of waste emissions, improve operation technology and management methods, thereby improving the working conditions and environment for workers, increasing their work enthusiasm and efficiency. e. Clean production can improve the relationship between industrial enterprises and environmental management departments, resolving the contradiction between environment and economy. Effective ways to achieve clean production: 1. Minimize or do not use toxic and harmful raw materials, which requires full consideration in process design. 2. Use non-toxic and harmless intermediate products. 3. Reduce or eliminate various hazardous factors in the production process, such as: high temperature, high pressure, low temperature, low pressure, flammable, explosive, strong noise, strong vibration, etc. 4. Use less waste, waste-free processes. 5. Adopt efficient equipment. 6. Material recycling. 7. Simple and reliable operation and control. 8. Necessary end-of-pipe treatment (1) As a final inspection and treatment, not in priority; (2) As a pretreatment measure for sending waste to an external centralized treatment facility.

The emergence and development of clean production
1. Environmental issues facing humanity
Environmental issues have evolved from local and regional problems into a global ecological crisis, including phenomena such as greenhouse effect (global warming), acid rain, ozone layer depletion, severe desertification, freshwater scarcity, biodiversity loss, toxic chemicals and hazardous waste, marine and coastal pollution, deforestation, and energy resource shortages, all of which pose hidden dangers to human survival.
Regional environmental pollution issues
Mid-1980s status (developed countries)
Global environmental pollution issue (starting in the mid-1980s)
Acid rain, greenhouse effect, ozone layer depletion
Traditional environmental management measures
Pollution first, treatment later (end-of-pipe treatment)
Pollutants are continually increasing
Wastewater -- Production Wastewater, Domestic Wastewater
Waste Gases – Industrial Waste Gases, Process Waste Gases
Waste Materials -- Offcuts, Packaging Materials, Office Waste, Household Waste
Noise - Machine and equipment noise, construction noise
Adhering to the traditional model characterized by extensive resource consumption and operations, economic development is increasingly陷ing into two major dilemmas: resource scarcity and environmental pollution. Firstly, the traditional development model not only causes significant environmental damage but also wastes vast amounts of resources, accelerating the depletion of natural resources and making sustainable development difficult. Secondly, industrial pollution control policies that focus on end-of-pipe treatment neglect the control of pollution throughout the process and fail to eliminate pollution at its root. Clean production, however, effectively addresses these two issues and boasts the following distinct advantages:
a. In terms of clean production, we utilize energy-saving, consumption reduction, pollution reduction, and cost reduction to improve product quality and enhance the economic benefits of the enterprise, thereby strengthening its market competitiveness. On the other hand, this approach can significantly decrease the pollution load of end-of-pipe treatment, save a substantial amount of environmental protection investment (initial investment and facility operation costs), and boost the enterprise's enthusiasm and awareness for pollution prevention and control.
b. Clean production maximizes the use of resources and energy through recycling or reuse, converting raw materials into products to the fullest extent, and eliminating pollution within the production process. By improving equipment or altering combustion methods, energy efficiency can be further enhanced, thereby reducing the generation and emission of pollutants, conserving resources and energy, and achieving greater returns with less investment, yielding significant economic benefits.
c. Clean production can avoid or reduce the one-time pollution caused by inadequate transformation in terminal treatment, as it employs a multitude of source reduction measures. This not only decreases the usage of raw materials containing toxic components but also enhances the conversion rate of raw materials, reduces logistics loss, and decreases the amount and emissions of pollutants, thereby minimizing the chances of secondary pollution.
d. Clean production can to a certain extent replace toxic products, toxic raw materials, and energy sources, substitute for processes and equipment with high pollution discharge, improve operational techniques and management methods, thereby enhancing workers' labor conditions and work environment, and boosting their work enthusiasm and efficiency.
e. Clean production can improve the relationship between industrial enterprises and environmental management departments, resolving the contradiction between the environment and the economy.
