Nowadays, although the green development of papermaking defoamers has become an inevitable trend in the industry, there are still some challenges in the actual promotion process. How to overcome these challenges and achieve the green and sustainable development of defoamers is an urgent problem that needs to be solved in the current paper industry.

On the one hand, the increasingly strict environmental regulations have put forward higher requirements for the green development of paper defoamers, and the research and application of environmentally friendly materials will also become the focus of the green development of paper defoamers. In order to meet regulatory requirements, enterprises need to invest more funds and manpower in technology research and development, process improvement, and enhance the environmental performance and production efficiency of defoamers. However, this may pose certain difficulties for some small businesses. Therefore, the government should increase its support for environmental protection technologies, provide policy support and funding subsidies, encourage enterprises to increase research and development investment, and promote the green development of defoamers.

On the other hand, changes in market demand have also posed new challenges to the green development of papermaking defoamers. With the increasing demand for environmentally friendly products from consumers, paper companies need to pay more attention to the environmental performance and sustainability of defoamers. However, currently the price of environmentally friendly defoamers on the market is relatively high and the supply is limited. Therefore, enterprises should strengthen cooperation with suppliers, jointly promote the research and production of environmentally friendly defoamers, reduce their production costs and market prices, and improve their competitiveness in the market.

In response to the above challenges, paper companies should actively respond and take effective measures to promote the green development of defoamers. Firstly, strengthen technological research and process improvement to enhance the environmental performance and production efficiency of defoamers; Secondly, strengthen cooperation with suppliers to jointly promote the research and production of environmentally friendly defoamers; Finally, strengthen environmental management and supervision to ensure that defoamers do not cause environmental pollution during production and use. Only in this way can the green and sustainable development of papermaking defoamers be achieved in the future.
