Biological and Bio-Mechanical Technologies for Recycled Fibers to Regain Fiber Quality and Increase Secondary Feedstock in High Value-Added Paper Grades

The goal of this project is to develop new technologies for removing contaminants from recycled paper to less than 0.5% and to develop technologies for regaining or fiber quality without using only mechanical refining. The new technologies developed will help paper recycling industry to produce much cleaner pulp and higher quality fibers so more recycled fibers can be used in place of virgin fibers in high grade paper. The new technologies developed based on new enzyme applications will also reduce the energy consumptions in both contamination removal and fiber refining process and increase the yield of the fiber recycling.
