Effects of Eucalyptus globulus addition to softwood greaseproof paper production improved energy efficiency of greaseproof paper production

Year: 2025

Type: article

Abstract: The production of natural greaseproof paper is a highly energy extensive process typically involving intense refining of softwood pulp in order to yield a low porosity, high density sheet, with low air permeance. This study evaluates the addition of Eucalyptus globulus hardwood fibers to the softwood stock as an approach for reducing the specific refining energy needed on both machine-made, and laboratory-made papers. This addition reduced the average fiber dimensions, leading to a net saving of up to 160 kWh per ton produced paper within the refining, while either maintaining or improving the pulp and paper properties.
