The paper industry, as a resource intensive and environmentally-friendly industry, has become a global focus of attention for its green transformation and sustainable development. As a key additive in the papermaking process, defoamers' green innovation and sustainable development strategies are of great significance in promoting the green development of the entire industry.

The production of foam in papermaking and pulping process will not only affect production efficiency and product quality, but also may pose a potential threat to the environment and workers' health. Environmentally friendly defoamers, as an important tool to solve this problem, are gradually being widely used in the paper industry and have become an important driving force for promoting the sustainable development of the paper industry.

The development of environmentally friendly defoamers for modern papermaking and pulp fully considers environmental requirements, using raw materials and synthesis processes with low or even zero VOC emissions, effectively reducing pollution to the atmospheric environment. The environment-friendly defoamer reduces the waste of raw materials and energy consumption in the pulping process by effectively controlling foam. For example, the loss of wood fiber caused by slurry overflow caused by foam is avoided, and the resource utilization rate is improved. After the use of some new environmentally friendly defoamers, their residual components have a relatively small 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.

The continuous research and application of environmentally friendly defoamers for papermaking and pulp making have promoted technological innovation in the papermaking industry. By combining new technologies such as biological enzyme technology, more efficient, environmentally friendly, and multifunctional defoamer products have been developed, further enhancing the comprehensive benefits of papermaking and pulp production. The application of environmentally friendly defoamers has also enhanced the environmental awareness of the paper industry. Enterprises pay more attention to using environmentally friendly materials and processes in the production process, reducing pollution and damage to the environment, and achieving coordinated development of economic and environmental benefits. With the widespread application of environmentally friendly defoamers and other green chemicals, the paper industry is gradually transitioning from traditional high pollution and high energy consumption to green, low-carbon, and sustainable development. This helps to enhance the competitiveness and sustainable development capabilities of the entire industry.
