Although the green development of papermaking defoamers has become an important trend in the industry, there are still many challenges in practical operation. At present, the technological research and development of green defoamers is still in its infancy, and many key technologies have not yet been breakthrough. This limits the performance and application range of green defoamers.

Compared to traditional defoamers, the production cost of green defoamers is higher. This increases the burden on paper companies and affects the promotion and application of green defoamers. Despite the many advantages of green defoamers, some paper companies still hold a wait-and-see attitude towards them. The low market acceptance has limited the development of green defoamers.

In response to these challenges, the government and enterprises should increase investment in the research and development of green defoamers, break through technological bottlenecks, and improve product performance and application scope. The government can introduce relevant policies to encourage paper companies to use green defoamers, such as providing tax exemptions, funding subsidies, and other preferential policies.

Strengthen the market promotion and marketing of green defoamers to increase market acceptance. By holding technical exchange meetings, product exhibitions, and other activities, paper companies can understand the advantages and application effects of green defoamers. Strengthen cooperation and exchange with international advanced enterprises, introduce advanced technology and management experience, and promote the green development of papermaking defoamers.

The green development of papermaking defoamers faces many challenges, but these challenges can be effectively addressed through strategies such as increasing research and development investment, policy guidance, market promotion, and international cooperation. In the future, with the continuous advancement of technology and increasingly strict environmental requirements, paper defoamers will become more environmentally friendly and efficient, contributing to the sustainable development of the paper industry.
