Recycling Method
GAINESVILLE, Fla.—Hassan El-Shall, a University of Florida engineering professor, holds up the paper pulp Thursday (7/28) that is the product of a new recycling method he and his colleagues developed to help paper plants save trees and enhance profits by recycling more types of paper more cheaply than possible with current methods. The technique removes inks, pigments and dyes from many types of paper — newsprint, glossy magazines, even tissue — while increasing the amount of recycled paper that plants can use to produce new paper. Current methods typically result in a finished product that is inferior to the original, while the UF technique produces paper nearly the same quality as the virgin stock, said El-Shall, associate director for research at UF’s Engineering Research Center for Particle Science and Technology.
