TB49: Puckerbrush Pulping Studies

A study was made of the potential of weed trees and shrubs, called puckerbrush, native to the state of Maine as a source of fiber for the paper industry. Six species—gray birch, red maple, pin cherry, aspen, alder, and willow—were used in the study. All components of each species were studied separately, including stemwood, branches, roots, and stump. In addition, two mixtures of components of each species were studied: Composite 1, a representative mixture of stem, branches, roots and stump, and Composite 2, a mixture of stem and branches.https://digitalcommons.library.umaine.edu/aes_techbulletin/1144/thumbnail.jp
