The green and sustainable development of defoamers in the paper market faces many challenges, but at the same time, it also harbors enormous opportunities. We will analyze these challenges and propose corresponding countermeasures.

1、 Technical challenges and insufficient R&D investment

Currently, the green transformation of defoamers is facing technological challenges. Traditional defoamers often contain harmful substances, while the development of environmentally friendly defoamers requires significant investment of funds and human resources. However, due to insufficient research and development investment, the progress of developing environmentally friendly defoamers has been slow. To address this challenge, the government and enterprises should increase research and development investment, encourage technological innovation and industry university research cooperation, and promote the research and application of environmentally friendly defoamers.

2、 Cost issues and market acceptance

The production cost of environmentally friendly defoamers is often higher than that of traditional defoamers, which limits their market promotion and application. Meanwhile, due to consumers' insufficient understanding of environmentally friendly defoamers, the market acceptance is also low. In order to reduce production costs and improve market acceptance, the government can provide policy support and funding subsidies to encourage enterprises to adopt environmentally friendly raw materials and efficient synthesis processes. At the same time, strengthen environmental protection publicity and education, and enhance consumers' awareness and demand for environmentally friendly defoamers.

3、 Insufficient enforcement and supervision of regulations

Although the government has formulated a series of environmental regulations, there are still shortcomings in the actual implementation and supervision process. Some companies often use defoamers that do not meet environmental standards in order to reduce costs and pursue profits. In order to strengthen the enforcement and supervision of regulations, the government should increase the punishment for illegal enterprises, and at the same time strengthen environmental training and guidance for paper companies to enhance their environmental awareness and capabilities.

4、 International Cooperation and Resource Sharing

Faced with global environmental challenges, international cooperation and resource sharing have become important ways to promote the green and sustainable development of defoamers. By strengthening cooperation and exchanges with international advanced enterprises and research institutions, environmental protection technologies and experiences can be shared, promoting the green transformation and sustainable development of defoamers. At the same time, actively participate in international environmental organizations and activities to jointly address global environmental issues.
