Old: trees β pulp + black liquor
New: trees β pulp + lignin + organic acids
Researchers at the Georgia Institute of Technology are developing a modular process to help pulp mills create new revenue from the black liquor they produce.
While studying ways to improve the energy efficiency of pulp production, scientists found they could do more than reduce the water content of black liquor. They could produce multiple products, turning kraft pulp mills into kraft biorefineries.
Best of all, the changes can be implemented gradually within existing plants. Sustainability increases, jobs are retained, and the pulp and paper industry could see a big boost.
