Enzymes for Papermaking

Enzymes are sustainable biocatalysts used to optimize pulp and paper processes. Xylanases reduce refining energy and aid bio-bleaching, while cellulases improve fiber modification. Lipases/amylases enhance deinking in recycled paper, and pectinases assist in non-wood pulping. Enzymes also control microbial slime (proteases/amylases) and sticky deposits. Benefits include lower chemical use, energy savings, and eco-friendly production without compromising pulp quality. Ideal for kraft, recycled, and specialty papers, enzymes support efficient, sustainable papermaking.

Technical Parameters

Product Name	Xylanase enzyme
Function	Bio-bleaching, lignin accessibility improvement
pH Range	5.0–9.0 (optimal: 6.0–7.5)
Temperature Range	40–65°C (optimal: 50–60°C)
Dosage	0.2–1.0 kg/ton pulp
Impact	Reduces chlorine demand by 15–30%

Product Features

1. Targets xylan (a hemicellulose component) without damaging cellulose fibers, preserving pulp strength.
2. Loosens residual lignin in kraft pulp, reducing chlorine-based bleach chemicals by 15–30%.
3. Lowers refining energy by improving fiber flexibility (saves 10–20% energy in mechanical refining).
4. Works effectively in pH 5.0–9.0 (optimal: 6.0–7.5), compatible with most pulp processing conditions.
5. Active at 40–65°C (optimal: 50–60°C), suitable for industrial pulp heating stages.

Main Application

Enzyme applications have been proposed for pulp and paper manufacture to enhance pulp bleaching, pulp refining, deinking, cellulose purification, deposit control,and papermaking.For mechanical pulping, wood fibers are separated and refined using mechanical actions that are energy intensive and lead to some damage of the fibers. In order to sustainable development strategy of paper industry, we need to get the most value from each piece of wood, let us work together to progress.

Instruction of Using

Enzymes For Bleaching
Bleaching is the process of removing lignin from the chemical pulp. This is an essential step for aesthetic purposes and to improve the paper property. Recently, a large amount of chlorine and other chlorine chemicals are used. The by-products of using these chemicals are very toxic and are harmful to the environment. Enzymes are a better, simple, and cost-effective alternative.

Enzymes For Beating Modification
In fibre beating modification, fibre is modified using pulp and paper enzymes to decrease the energy consumed during the production of thermomechanical pulps. They are also used to make pulps easy to beat. They work the best when combined with an alkaline pre-treatment.

Enzymes For Resin Control
Resin is a component of wood that composes of fats, waxes, fatty acids. Though they comprise only 10% of the wood, they are very problematic. Different types of pulp and paper enzymes like lipases have been used for the removal of this resin. This reduces the problems that can create in the future because of the resin. This resins also gets deposited in the paper machine, and it can easily be cleaned using enzymes. This also helps in improving the quality of the pulp and paper.

Enzymes For Sizing Press
Starch is main used in paper making industries in the process of sizing press. Sizing is done to reduce the chances of the paper, absorbing any liquid when dried. This makes sure that inks and paints don’t get absorbed by the paper after drying and remain on it. This also reduces the bloating of paper. This starch is modified using enzymes to get the best results. To saves more cost for the paper mills.
