Container Industry Will Unify New Water-based Environmental Protection Coatings

Jun 06, 2020

The China Container Industry Association recently held the "Conference of the China Container Industry Association's Green Environmental Protection Action and the Signing Ceremony of the VOCs Governance Self-Regulation Convention" in Shanghai. The "China Container Industry Association's Green Environmental Protection Action Declaration" released this time proposes that the container industry should actively cooperate with the national environmental protection new policy and adopt the industry self-discipline convention to "jointly commit and act together" to implement a new type of water-based environmental protection coatings within a limited time in the country. To ensure that the entire industry achieves significant reductions in organic waste gas (VOCs) emissions by the end of 2017.

Our country's container manufacturing capacity has an absolute global competitive advantage, and its production, sales and export volume have accounted for more than 90% of the global market in the past decade. However, the container manufacturing industry has traditionally used solvent-based paint for coating. This coating process produces a large amount of VOCs (volatile organic compounds). VOCs are industrial waste gas that can produce PM2 through photochemical reactions in the air. 5. Therefore, the control of VOCs from the source is a key point in the prevention and control of air pollution in my country.

Our country's container manufacturing enterprises are ranked among the top ten in all industries in China based on the total amount of VOCs converted using solvent-based coatings. Moreover, most of these enterprises are concentrated in eastern coastal cities such as the Pearl River Delta, the Yangtze River Delta, and the Bohai Bay Rim, and have always been the key targets of local air pollution prevention and control. Although China’s container manufacturing enterprises have continuously updated VOCs elimination technology for more than a decade, with the development of the national economy and society, the state has paid more and more attention to the prevention and control of atmospheric pollution, especially after the implementation of the “new atmospheric law” The emission restriction standards have been revised and improved again, and China's current container manufacturing enterprises will face the dilemma of widespread violations of regulations.

As early as ten years ago, some visionary paint suppliers and container manufacturers have embarked on a new generation of environmentally friendly paints to completely solve the VOCs emission problem at the source. After years of hard work, replacing solvent-based coatings with water-based environmentally friendly coatings has gradually become the industry consensus. However, due to the process controversy of water-based environmental protection coatings in some processes, the industry does not have uniform standards and operating specifications, and the practical problems of higher costs than solvent-based coatings, individual companies cannot promote the widespread use of water-based coatings in the industry. Under the "bad currency drives good currency" mechanism, the industry as a whole has fallen into the dilemma of "whoever protects the environment and loses, and who insists on closing the door" in the implementation of VOCs emission reduction actions.

Faced with this situation, starting in 2015, the China Container Industry Association convened industry experts to form a VOCs governance working group. It took a year to clarify the technical route for the uniform promotion and application of waterborne coatings throughout the industry; supporting the formulation of product standards, process specifications, quality testing standards for container waterborne coatings, and VOCs emission accounting standards, etc., which filled the waterborne environmental protection coatings in China's container industry. Standard blank. On this basis, according to the "high concentration" characteristics of China's container manufacturing enterprises, it initiated the formulation and organization of relevant member units to sign the "Convention on Self-Discipline of VOCs Governance of the China Container Industry Association", "common commitment, joint action, mutual supervision, and self-punishment for breach of contract." , Within the time limit of the national division, the simultaneous implementation of new water-based environmental protection coatings.

According to the assessment of experts organized by the industry association, the results of such a move will reduce the emissions of VOCs in the national container industry by about 85% compared to the production of VOCs in the traditional paint coating process (absolute emission reduction rate); Reduce emissions by more than 70%.

The China Container Industry Association organized this action, adhered to the law, based on the premise of technological behavior, combined with the industry's own characteristics, adopted environmental protection before commercial competition standards, and promoted the member units to jointly assume social responsibility for atmospheric governance; adhere to fairness, justice, The principle of openness, from the standpoint of maintaining long-term sustainable and healthy development of the industry, fully promote democracy, and listen to the opinions of relevant member units and external experts on key issues on many occasions; insist on acting in accordance with the industry charter and give full play to the members of the association’s standing council To lead the role, to promote the relevant members of the association to abandon the disputes for their own interests for the sake of national environmental protection, seek common ground, build mechanisms, stress credit, promise self-discipline and compliance, and implement their respective responsibilities for reducing emissions of VOCs.

In the 13th Five-Year Plan outline just adopted at the 4th Session of the 12th National People's Congress, it was proposed to "innovate environmental governance concepts and methods, implement the strictest environmental protection system, strengthen the main responsibility of polluters, and form the government, enterprises, and the public. A co-governance environmental governance system to achieve overall improvement in environmental quality." This is the first time China Container Industry Association has organized a unified organization, unified standards, unified actions, self-restraint and self-supervision of large-scale VOCs emission reduction actions. It has reference significance for how various industries combine the characteristics of the industry, implement the new atmospheric law, and implement the development tasks set out in the "Thirteenth Five-Year Plan". It has been highly valued by national and local environmental protection departments, experts and scholars.
