As one of the traditional high energy consuming and high polluting industries, the paper industry's green transformation has become an inevitable trend. As an important additive in the papermaking process, defoamers have significant implications for promoting the green and sustainable development of the entire industry through their green transformation path. The green development of defoamers in the paper industry can first be achieved by using natural or biodegradable materials in the selection of raw materials to prepare defoamers and reduce their impact on the environment. Simultaneously optimizing production processes, reducing energy consumption and emissions, and improving resource utilization efficiency. Develop efficient, low toxicity, and low residue defoamers to reduce harm to the environment and human health. Realize the recycling of defoamers and the resource utilization of waste, and build a closed-loop production system.

Currently, the performance and cost of environmentally friendly defoamers still face certain challenges and require continuous research and innovation. Although environmentally friendly defoamers have many advantages, their acceptance in the market still takes time and requires joint efforts from both inside and outside the industry to promote. The guidance and support of government policies are crucial for promoting the green transformation of defoamers in the paper industry.

In the future, enterprises need to increase their research and development efforts to develop environmentally friendly defoamers with better performance and lower costs. Enhance the market awareness and acceptance of environmentally friendly defoamers through industry exhibitions, technical exchange meetings, and other channels. Actively seek government support in taxation, funding, policies, and other aspects to promote the green transformation of defoamers in the paper industry.

The green path of defoamers in the paper industry requires joint efforts from both inside and outside the industry, through measures such as greening raw materials, production processes, products, and promoting circular economy, to promote the green and sustainable development of the entire industry. At the same time, it is necessary to overcome technological bottlenecks, improve market acceptance, and strive for policy support to contribute to the green development of the paper industry.
