Upgrading old corrugated cardboard (OCC) to dissolving pulp

Cellulose, 2016
Delignification and pentosan dissolution of old corrugated cardboard (OCC) pulp was carried out using formic acid (FA) followed by alkaline extraction at atmospheric pressure. The kappa number of the initial OCC pulp was 41.4, which was decreased to 18.0 after 3.5 h of formic acid treatment.

Passivation of pressure sensitive adhesive stickies by addition of acrylic fibers to OCC pulp before papermaking

TAPPI Journal, 2016
This study investigated the addition of acrylic fiber to old corrugated container (OCC) pulp as a possible means of overcoming adverse effects of water-based pressure sensitive adhesives during manufacture of paper or paperboard. Such adhesives can constitute a main source of stickies, which hurt the efficiency of the papermaking process and make tacky

Refining Treatment Could Contribute to Restoring the Strength Properties of OCC Pulp

2004
The volume of recovered paper used globally is almost equal to the volume of new chemical pulp or four times that of mechanical pulp. Recycling has gained a very strong ground indeed. Nowadays, in some countries the paper industry cannot survive without recycled fibers.

Phosphomolybdic acid-catalyzed oxidation of waste starch: a new strategy for handling the OCC pulping wastewater

Environmental Science and Pollution Research, 2022
When old corrugated cardboard (OCC) is returned to the paper mill for repulping and reuse, the starch, which is added to the paper surface as a reinforcement agent, is dissolved into the pulping wastewater. Most of the OCC pulping wastewater is recycled to save precious water resources; however, during the water recycling process, the accumulation of ...
