Grafting nanocellulose with diethylenetriaminepentaacetic acid and chitosan as additive for enhancing recycled OCC pulp fibres [PDF]
Cellulose, 2022 Abstract This paper develops a novel paper additive for effectively recycling old corrugated container (OCC) by functionalizing nanocellulose (NC) with diethylenetriaminepentaacetic acid (DTPA) and chitosan (CS), and investigate the reinforcing mechanisms and effect of the developed additive on the physical properties of recycled OCC ...

CHEMICAL TREATMENT OF RECYCLED PULP FIBRES FOR PROPERTY DEVELOPMENT: PART 3. EFFECTS ON OCC PULPS
Drewno. Prace Naukowe, Doniesienia, Komunikaty = Wood. Research Papers, Reports, Announcements, 2020 Chemical treatment with sodium hydroxide, formamide and ethyl acetate is shown to affect certain properties of paper made from recovered fibres. Sodium hydroxide treatment improves the brightness of sheets by approx. 0.12-17.2% under similar recycling conditions.

Effects of pulp preparation and papermaking processes on the properties of OCC fibers [PDF]
BioResources, 2011 Changes of the pore structure of recycled fibers and the strength properties of papers produced by old corrugated container (OCC) recycled fibers were studied, after they were subjected to different stock preparation and papermaking processes. In this paper, the effects of beating, sizing, pressing, and drying on fiber properties were investigated, and

Effect of Mixing Different Contents of OCC Pulp on NSSC Pulp Strength
BioResources, 2014 This research was conducted to study changes in mechanical properties due to mixing of old corrugated container (OCC) pulp with virgin neutral sulfite semi-chemical (NSSC) pulp. The OCC pulp was collected after removal of printing, glued parts, and unwanted additives.

Upgrading OCC and recycled liner pulps by medium-consistency ozone treatment
TAPPI Journal, 2007 This study evaluated the application of low levels of ozone at medium consistency to improve the properties of old corrugated container (OCC) pulp. Pulps obtained from kraft liner and corrugating medium were also tried. Ozone reduces the kappa number of the pulp, but the surface charge of the fiber is not changed.

An Optimum Mixture of Virgin Bagasse Pulp and Recycled Pulp (OCC) for Manufacturing Fluting Paper
BioResources, 2013 This study evaluated the properties of fluting paper made with a blend of unbleached bagasse soda pulp (340 mL CSF freeness) and OCC pulp (250 to 300 mL CSF freeness) of 0:100, 10:90, 30:70, 50:50, 70:30, and 90:10 ratios by weight, respectively. Some handsheets at 120 g/m2 basis weight were made.

BioResources, 2013 In this study, old corrugated container (OCC) pulp was added in different ratios (5%, 10%, 15%, 20%, and 25% w/w) to unbleached virgin pulps of both European black pine and Scots pine, and its effects on paper properties were investigated. As a control, OCC pulp-free handsheets were separately produced from European black pine and Scots pine pulps. The

Chemical Modification of Laccase from Aspergillus oryzae and its Application in OCC Pulp
BioResources, 2016 Laccase activity and stability were improved and modified through the interaction between laccase amino acid residues (e.g., amino groups (-NH2) and carboxyl groups (-COOH)) and the chemical reagents thiourea dioxide (TDO) and L-phenylalanine methyl ester hydrochloride (L-PME). Compared with the control sample, the activity of the laccase modified with
