Supercritical carbon dioxide dewaxing of old corrugated containers

Journal of Applied Polymer Science, 2001
AbstractWax‐coated old corrugated containers (OCC) are not part of the paper recycling stream because a process to remove the wax coating is not presently available. Residual waxes influence fiber–fiber bonding, reducing the paper properties of recycled OCC as well as the paper machine operating efficiency. A procedure to dewax OCC is a major objective

Modification of old corrugated container pulp with laccase and laccase–mediator system

Bioresource Technology, 2012
Modification of the physical properties of old corrugated container (OCC) pulp with laccase or a laccase-mediator (ABTS, HBT, VA) system was investigated under select enzymatic concentrations and reaction times. The optimal conditions for laccase treatment shown to be using a laccase dose of 160U/g o.d.

Multilayer assembly of ionic starches on old corrugated container recycled cellulosic fibers

Polymer International, 2017
Abstract In this study, old corrugated container recycled fibers were treated with polyelectrolyte multilayers consisting of biopolymer cationic starch with two degrees of substitution (DS) each in combination with one anionic starch. Pulp zeta potential, paper strength and the thin layer ellipsometry technique were applied to examine

Performance characteristics of polyethylene/old corrugated container composites reinforced with carbon nanotubes

Journal of Composite Materials, 2016
The physical, mechanical, thermal, and flammability properties of high-density polyethylene/old corrugated container composites reinforced with carbon nanotubes are presented in this study. High-density polyethylene/old corrugated container composites with different loadings of carbon nanotube (0, 1, 3, and 5 phc) were prepared by melt compounding ...

Lignocellulosic hydrogel from recycled old corrugated container resources using ionic liquid as a green solvent

Journal of Environmental Management, 2020
Lignocellulosic hydrogels are valuable bio-products that have been considered widely in recent investigations. Also, application of low value recycled fibers for high value added products can be of much interest. In this respect, current research has focused on producing hydrogel from recycled old corrugated container (OCC) resources, using 1-butyl-3 ...

Removing paraffin‐based wax coatings from old corrugated containers using supercritical carbon dioxide

Journal of Applied Polymer Science, 2002
AbstractSupercritical carbon dioxide (SC‐CO2) extractions of paraffin‐based wax coatings from saturated and curtain‐coated old corrugated containers (OCC) are reported. Extractions were performed in a 500‐mL reactor (300 bar, 100°C, 50 g CO2/min and 1 h).

Electrocoagulation pre-treatment to simultaneously remove dissolved and colloidal substances and Ca2+ in old corrugated container wastewater

Chemosphere, 2021
An effective electrocoagulation pre-treatment (ECP) method was proposed to simultaneously solve the problems of the micro stickies deposition and high Ca2+ content in old corrugated container (OCC) papermaking wastewater during the recycling process. The optimal ECP condition was investigated. The results indicated that the effect of an Al electrode on

Use of Soy/PF resin for Old Corrugated Container (OCC)-wood Composites

Materials Letters, 2008
In this study, Old Corrugated Container (OCC) was used as the raw material for producing composite materials. The objective of this study was evaluation of boards made of various ratios (0:100, 25:75, 50:50, 75:25 and 100:0) of OCC flakes to wood particle mixtures (wt:wt) with addition of Soy/PF resin at three levels (3.5, 7 and 10%) and 1.5% wax.

Using industrial waste of old corrugating containers paper recycling mill in composite panels manufacturing

Journal of Reinforced Plastics and Composites, 2012
There is a considerable amount of waste produced daily from processing old corrugating containers. Dumping this waste product incurs a considerable cost to a paper recycling mill. In this study a sample of waste containing 45% fibrous and 55% non-fibrous solid was collected from an old corrugating containers paper-recycling mill and analyzed in a ...

Utilization of sugarcane molasses as a dry-strength additive for old corrugated container recycled paper

Composites Part B: Engineering, 2013
Abstract The objective of this study was to evaluate the ability of molasses, a low cost by-product of the sugarcane extraction, for improvement of the physicomechanical properties of old corrugated container (OCC) recycled paper as a dry-strength agent. The influence of fiber beating on the enhancing effect of molasses was also investigated.
