Analysis on Unfavorable Factors of Cleaner Production in Chemical Industry

Analyze the Unfavorable Factors of Cleaner Production in Anhui Chemical Industry Chemical Industry Chen Jinsi (Department of Environmental Engineering, Hefei University of Technology, Hefei 230009) Since the 1970s when the state proposed the principle of “prevention first, prevention and control combined”, the chemical industry has been making continuous efforts. To protect the environment. In the early 1980s, the chemical industry paid attention to the management of pollution sources; in the 1990s, it strengthened environmental protection law enforcement, vigorously carried out technological transformation, adjusted unreasonable industrial layout and product structure, and promoted “closed, suspended, forbidden, changed, and transferred” enterprises with serious pollution. In recent years, the working principle has continuously recognized that the prevention and control of chemical pollution cannot rely solely on the control of pollution at the end of sewage outlets. It must eliminate the pollution sources in the production process and implement the control of the entire chemical production process. In order to effectively promote clean production, the chemical industry has established clean production centers, drafted clean production implementation plans for the chemical industry, implemented pilot projects with effective results in some enterprises, and actively sought international financial and technical support, and achieved good economic results. Social and environmental benefits. However, in the process of promoting clean production, the chemical industry has been hindered by some difficulties for a long time, which has led to a slow progress in the implementation of cleaner production throughout the chemical industry. This article will briefly analyze the four factors that affect the clean production of the chemical industry.

1 Clean Production Law Incomplete Cleaner Production is a comprehensive measure of pollution prevention throughout the entire life cycle of production and the product. The current environmental legislation mostly focuses on the control of environmental pollution factors, while the protection of environmental factors and the management of production process flow lack relevant legislation. Practice has shown that many substances that may cause environmental pollution or pollution may not cause environmental pollution in normal use. Only the improper use or management of these substances or energy leads to running, leaking, dripping, leakage or energy. When the organization escapes, it can cause environmental pollution or other public hazards. Therefore, it is necessary to strengthen legislation on the control of the cleaner production process and carry out in-depth development of cleaner production, such as the "Vibration Control Law," "Light Pollution Control Law," "Waste Control Law," "Licensing System for Production Processes," and "toxic and hazardous chemicals." And dangerous goods management methods, etc.

As a new type of environmental management concept, cleaner production is an initiative of environmental management. It is not imposed on companies. Enterprises have the right to choose whether or not to implement them, and they have the right to choose the breadth and depth of their own companies' clean production. The subjective choices of enterprises lead to uneven promotion of clean production, and the implementation of different content is not uniform, and it is difficult to use uniform standards for evaluation and supervision. Therefore, it is necessary to strengthen the construction of a clean production standard database, establish a series of evaluation methods that comply with the statutory clean production procedures, and integrate cleaner production into a unified track to lay the foundation for legal supervision of cleaner production.

2 The insufficiency of product life cycle assessment (LCA) mainly considers the product's intervention and impact on the environment at various stages of its life cycle. Its purpose is to fully and correctly understand the relationship between the product and the environment, and to find improvements: (1) The deficiencies in the application of LCA are mainly reflected in the following four aspects: 1 Limitations of the scope of application. The product life cycle assessment only considers a single environmental issue and does not consider issues such as technology, economy, society, and benefits. With the deepening of WT0, domestic companies have to consider the credibility of their respective products, quality and performance. 2 Limits of evaluation scope. Product Life Cycle Assessment considers only the environmental impacts that have occurred or must occur, and does not consider environmental risks and necessary preventive and emergency measures. 3 limitations of the evaluation method. Regardless of their scope and level of detail, all product life cycle assessments include hypothetical values ​​and judgments that compromise one or both of these subjective factors. This product life cycle assessment contains both subjective and objective parts, and is not entirely a scientific one. 4 time and geographical limitations. Different time, regions, and different environmental cataloging data determine the limitations of environmental cataloging data within a specific period of time.

(2) LCA's theoretical difficulties: 1 In many practical aspects of LCA, due to the lack of recognized principles and methods, each step in the implementation depends on the implementer's understanding of the LCA method and his understanding of the evaluated system, as well as his own understanding and Habits are difficult to achieve. 2 The convention model in which the environmental inventory in the LCA is converted into an environmental load is not easily recognized. In the process of implementing LCA, a large number of environmental cataloging data sources represent the expectations of different appraisers on the evaluation object LCA, and the mutually acceptable LCA values ​​are very limited.

3 The three misunderstandings of cleaner production At present, most of the textbooks on cleaner production believe that clean production is only focused on production itself, with the goal of improving production and reducing pollution output. Under the influence of this guiding ideology, companies are widely Misunderstandings: 1 that clean production is to stay in the production process of the product, but did not pay enough attention to the extended areas of clean production. For example, cleaner production is not commonly used in project feasibility studies, environmental impact assessments, and other early stage predictions and evaluations. The preliminary design of the project and the design phase of construction drawings lack relevant review links and do not properly reduce pollutants at the source. There is a gap in the product's production and consumption areas, and the feasibility of reusable materials has not been carefully examined during product design. 2 The focus of cleaner production is on technological development. Some companies that have passed the IS014000 environmental certification often focus on environmental management and neglect technology development. In fact, clean production and IS014000 are all new ideas for environmental management. They only focus on different aspects. The former focuses on technological development, while the latter has a more concentrated management. The two should be combined effectively to achieve both the root causes and the environmental quality. 3 Some companies believe that clean production requires a lot of investment and strong technology support, while their own companies lack both funds and scientific and technological information, so they take a wait-and-see attitude. A large number of practices have proved that: Cleaner production can be implemented relying on the strength of the enterprise itself. Enterprises can develop special technical measures with less investment, so as to achieve energy saving, reduction of consumption, and hard translation!

Its significance is profound and its impact is far-reaching. Clean production as a political task. What is a pity is that it is difficult for companies to generally regard clean production as a political responsibility. Cleaner production cannot be implemented in all aspects of production.

(2) The shortage of funds has always been the difficulty for enterprises to carry out clean production. The sources of clean production funds for enterprises are nothing more than self-raising, credit support, and international cooperation. At present, credit support and international cooperation are not easily available to most companies. Clean production funds can only be allocated from enterprise accounts. However, most companies believe that the clean production investment has been slow, and misappropriate the company's other project development funds, making it difficult to include clean production special funds in the company's medium and long-term budget.

(3) Corporate clean production requires the support of corporate culture. The promotion, education, and encouragement of cleaner production are inseparable from corporate culture. As a carrier, corporate culture can implement cleaner production knowledge in every job position and even in the daily life of employees. However, corporate culture is only carried out in large-scale enterprises with conditions, but the majority of small and medium-sized enterprises have no conditions to cultivate corporate culture.

Cleaner production is a branch of industrial ecology. It is a young discipline in the field of environmental science. Its theory and practice require patience, scientific research, industrial and mining companies work together to explore a clean production theory and practice that suit China's national conditions. At the same time, the development of cleaner production is inseparable from the protection of the national laws. Enterprises should actively change their concepts and effectively take the “prevention-oriented, prevention-control-integration” clean production road and incorporate clean production in China into a virtuous circle.
