description The present invention is a method for producing pulp from fibrous lignocellulose material using a treatment step which exposes the material to oxalic acid, or oxalic acid and sodium bisulfite, prior to pulping. The pulping of the resulting product requires less energy input and provides a pulp having enhanced physical properties as compared to untreated materials.
