Co2 Assisted Glycol Pulping: A New Concept Advancing High-Yield, Sustainable Pulp Production
Short Introductive summary
The pulp and paper industry faces mounting pressure to improve process efficiency and sustainability, particularly by reducing emissions and maximizing resource utilization. Conventional pulping methods, such as kraft and sulphite processes, typically yield around 50% pulp, with the remaining wood components combusted, generating significant emissions. To address these challenges, we developed a novel sulphur-free pulping concept utilizing CO2 gas, water, and glycol as sustainable reagents. In summary, our CO2–glycol pulping performed from lab scale to bench-scale offers high-yield chemical pulp production with zero-sulphur emissions. Our pulping concept is much simplified, and the process does not involve any metals or sulphur based dangerous chemicals. The pulping products can be easily purified from the feed chemicals. This research aligns with green chemistry principles and emission-free pulping goals that support the transition to sustainable pulp and paper manufacturing.
