Researchers unlock new method to transform paper pulp into reactive cellulose
Scientists have developed a process to convert standard paper-grade chemical pulps into highly reactive cellulose, potentially opening new applications in biochemicals and materials. The advance could reshape how paper mills repurpose their feedstock and compete in higher-value markets beyond traditional paper products.
Originaltitel: Converting paper grade chemical pulps to highly reactive cellulose
<p>In pursuit of sustainable alternatives to fossil-based materials, cellulose-based products, such as regenerated cellulose and cellulose derivatives, have attracted increasing attention. These materials offer biodegradability, biocompatibility, and a wide range of adjustable properties. However, their production relies on dissolving pulps, which are significantly more expensive than standard paper-grade pulps due to high raw material and processing costs. In this study, a potential route for converting standard bleached chemical pulps into more reactive cellulose was investigated, targeting applications in cellulose derivatives and regenerated materials. The method is based on acidic treatment followed by cold alkali dissolution and precipitation. Results show increased chemical reactivity and partial hemicellulose removal, suggesting a promising path toward low-cost alternatives to conventional dissolving pulp.</p>
