Przybysz, K., Małachowska, E., Martyniak, D., Boruszewski, P., Iłowska, J., Kalinowska, H., and Przybysz, P. (2018). "Yield of pulp, dimensional properties of fibers, and properties of paper produced from fast growing trees and grasses," BioRes. 13(1), 1372-1387.


Paper is produced mainly from wood fibrous pulps, which has been increasingly replaced by pulps from fast growing plants due to limited wood resources. In this work, properties of cellulosic pulps produced by the sulfate method from four fast growing grasses, poplar cultivar ‘Hybrid 275’, and European larch, as well as pine and birch wood chips, were compared. In addition, the cellulosic pulp yield, dimensions of fibers contained in the pulps and mechanical and optical characteristics of paper sheets produced from the pulps were compared. The pulp yield of the poplar cultivar ‘Hybrid 275’ (51.6%) was almost 5% higher than birch pulp (47.0%). Moreover, all of the investigated tensile properties of paper made from ‘Hybrid 275’ pulp were higher than for paper produced from birch pulp. Fast growing grasses, despite lower pulp yield (34.0 to 47.1%), showed comparable tensile properties to birch. Therefore, these pulps are promising raw materials for papermaking.
