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.

The influence of laccase/histidine system on the properties of OCC pulp fibers, and of handsheets made thereof

Nordic Pulp and Paper Research Journal, 2019
Abstract For improving the physical properties of old corrugated container (OCC) fiber, the laccase/histidine system was used in this paper. Firstly, the paper studied the optimum conditions that the laccase/histidine system modified the OCC fiber, including enzyme dosage, histidine dosage, reaction time, reaction temperature, and pH ...

Improving wet and dry strength properties of recycled old corrugated carton (OCC) pulp using various polymers

Carbohydrate Polymers, 2013
In this study, the application of different dosages of low and high molecular weights (MW) of chitosan (Ch), cationic starch (CS) and poly vinyl alcohol (PVA) were systematically investigated using old corrugated carton (OCC) furnishes. Various sequences of above-mentioned polymeric additives were also examined to find out the optimal combination for ...

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.
