In the paper industry, the use of defoamer is crucial to control foam in the production process, which directly affects the quality and production efficiency of paper. However, traditional defoamers may contain harmful components to the environment, which is not conducive to achieving green manufacturing and sustainable development goals. Therefore, promoting green innovation and sustainable development of defoamers in the paper industry requires starting from the following aspects.

In the future, it is necessary to develop new environmentally friendly raw materials, such as bio based materials, renewable materials, etc., to replace traditional high polluting raw materials. Develop efficient, low toxicity, and low residue new varieties of defoamers by combining cutting-edge technologies such as biotechnology and nanotechnology. Optimize production processes, reduce energy consumption and emissions, improve resource utilization and product quality.

Build a closed-loop production system to achieve the recycling of defoamers and the resource utilization of waste. Strengthen cooperation and communication between upstream and downstream enterprises in the supply chain, and jointly promote green transformation and sustainable development. Actively seek government support in policies and regulations to promote the green and sustainable development of defoamers in the paper industry.

Taking a certain paper-making enterprise as an example, the enterprise uses biobased raw materials to prepare environmentally friendly defoamers, and combines advanced production processes and equipment to achieve efficient utilization of defoamers and resource utilization of waste. At the same time, the company actively collaborates with upstream and downstream enterprises in the supply chain to jointly promote green transformation and sustainable development. This practical case provides useful reference for the green innovation and sustainable development of defoamers in the paper industry.

The green innovation and sustainable development strategy of defoamers in the paper industry require joint efforts from both inside and outside the industry to promote the greening and efficiency of defoamers through paths such as raw material innovation, technological innovation, and process innovation. At the same time, it is necessary to establish a circular economy system, strengthen green supply chain management, and strive for policy and regulatory guidance to contribute to the green development of the paper industry. Through the reference and promotion of practical cases, it is believed that the green innovation and sustainable development of defoamers in the paper industry will achieve more significant results.
