As an important pillar of the national economy, the paper industry faces challenges such as high resource dependence, high energy consumption, and significant environmental impact. In the context of promoting green and sustainable development, defoamers, as key additives in the papermaking process, are particularly important for their green, efficient, and sustainable development.

With the increasing awareness of environmental protection, traditional defoamers containing volatile organic compounds (VOCs) that are not easily biodegradable are gradually being phased out. In the future, the paper industry will pay more attention to using environmentally friendly defoamers made from natural or biodegradable materials. These defoamers are non-toxic, tasteless and environmentally friendly. They can not only effectively eliminate foam, improve paper quality and production efficiency, but also significantly reduce environmental pollution.

Under the concept of sustainable development, the paper industry is striving to improve resource utilization, reduce raw material waste and energy consumption. As an important auxiliary material in the papermaking process, the efficient utilization of defoamers is of great significance for achieving this goal. In the future, defoamers will pay more attention to reducing pulp overflow and wood fiber loss during pulping by accurately controlling foam, and reduce the additional energy consumption required to deal with foam problems. In addition, the residual components of the new defoamer after use have little impact on the subsequent processing of pulp and the recycling of paper, which is conducive to achieving closed-loop production and resource recycling in the paper industry.

Technological innovation is an important driving force for promoting the green development of defoamers in the paper industry. In the future, the research and development of defoamers will pay more attention to the direction of high efficiency, environmental protection, and multifunctionality. For example, a new type of defoamer developed using biological enzyme technology can not only defoam, but also promote fiber degradation and modification to a certain extent, improving the floatability of pulp and the strength of paper. This multifunctional defoamer will further enhance the comprehensive benefits of papermaking and pulp production, providing strong support for the green development of the papermaking industry.

The green development trend of defoamers in the future paper industry will pay more attention to environmental protection, efficient resource utilization, and technological innovation. By adopting environmentally friendly raw materials, improving resource utilization, and developing multifunctional defoamers, the paper industry will move towards a greener, low-carbon, and sustainable direction. This will help promote the green transformation of the paper industry and contribute to the construction of an ecological civilization society.
