In the future, research and development of defoamers based on bio based raw materials such as natural plant extracts and microbial fermentation products will reduce reliance on traditional petrochemical raw materials and lower carbon emissions during production. Ensure that defoamers are easy to decompose in the natural environment after use, reduce water and soil pollution, and choose ingredients that are easy to biodegrade. Avoid using substances that are harmful to human health and the environment, such as heavy metals, persistent organic pollutants, etc., to ensure the safety of defoamers.

Through technological innovation, the efficiency of defoamers can be improved to achieve ideal defoaming effects at lower usage levels, reducing resource consumption and waste generation. Develop composite defoamers with multiple functions such as defoaming, anti foaming, anti-corrosion, thickening, etc., reduce the types of additives, and simplify the production process.

Explore ways to recycle and reuse waste materials in the production process of defoamers, such as properly treating unreacted raw materials, by-products, or wastewater and reintroducing them into the production cycle. Collaborate with other industrial processes such as wastewater treatment and waste incineration to achieve resource sharing and minimize waste.

Priority should be given to raw material suppliers who adopt environmentally friendly production processes and have obtained environmental management system certifications such as ISO 14001. Adopting low-carbon transportation methods to reduce energy consumption and emissions during transportation, while optimizing packaging design to minimize the use of packaging materials and waste.

Increase investment in the research and development of green defoamer technology, including the exploration of new bio based raw materials and the study of efficient defoaming mechanisms.

Establish cooperative relationships with universities and research institutions, accelerate the transformation and application of scientific and technological achievements, and promote the green upgrading of defoamers in the paper industry.

Strive for government policy support in taxation, funding subsidies, and environmental standard setting, and encourage enterprises to adopt green defoamers.

Through industry conferences, exhibitions, media promotion, and other means, we aim to enhance consumers' awareness of green paper products and create a market demand driven market.

In summary, the green innovation and sustainable development of defoamers in the paper industry require efforts from multiple aspects, from raw material selection, product design, production process to supply chain management. Every step needs to implement the green concept, while relying on technological innovation and policy guidance to jointly promote the transformation and upgrading of the industry.
