Under the trend of green paper manufacturing, the environmental innovation and sustainable development of defoamers

Against the backdrop of increasingly stringent global environmental regulations, the paper-making industry is facing the challenge of reducing emissions and consumption. The application of defoamers not only solves process problems but also promotes sustainable development through the innovation of environmentally friendly formulas.

In the past, paper mills relied heavily on mineral oil or silicone-based defoamers, but these substances could affect wastewater treatment systems, increase chemical oxygen demand (COD) loads, and some harmful substances would remain in the paper, hindering subsequent recycling. The new generation of bio-based defoamers, utilizing natural oils or polyether modification technology, are biodegradable and reduce water pollution. Furthermore, the high compatibility of bio-based defoamers perfectly matches the recycled fiber process, enhancing the utilization rate of waste paper. What deserves our attention more is the non-toxicity of bio-based defoamers, which avoids posing health hazards to operators.

The greenification of defoamers is not only a technological iteration, but also a crucial lever for the paper industry to achieve environmental innovation and sustainable development goals. In the future, with breakthroughs in biotechnology, defoamers may become a part of the circular economy.
