The pulp and paper industry are a large and essential sector that processes raw materials like wood, recycled paper, or agricultural residues into pulp, which is then used to produce various paper products. It plays a critical role in supplying products such as printing paper, packaging materials, tissue products, and specialty papers. Here’s an overview of the key aspects of the pulp and paper industry:

The raw materials used in paper industry are:

1. Wood: The primary raw material for making pulp. Softwood (e.g., pine) and hardwood (e.g., eucalyptus, birch) are commonly used, with softwood providing longer fibres that give strength to paper, while hardwood fibres offer smoothness.

2. Recycled Paper: Recovered paper is a significant raw material in industry, used in the production of recycled paper and packaging products, reducing the demand for virgin wood pulp.

3. Non-Wood Materials: Agricultural residues like straw, bamboo, bagasse (sugarcane residue), and other Fiber crops are also used in some regions.

Xylacid: Xylacid is produced by a modified species of Aspergillus by SSF technique. Xylacid is an endo-1,4- beta xylanase. Xylanase is a group of enzymes that break down Xylan, a major hemicellulose component found in plant cell walls. In the paper industry, xylanases play an important role in improving the efficiency of pulp bleaching processes, reducing chemical use, and enhancing the overall quality of paper products.

Recypa: Recypa is an enzymatic blend formulation for de-inking of papers. Printed wastepaper is an important source for producing recycled paper. Recycling of printed wastepaper generally requires de-inking and bleaching of the printed wastepaper pulp to a suitable brightness before being used in the production of recycled paper.

Dexamyl HTP: Dexamyl HTP is a thermostable alpha amylase designed for application in production of paper produced from a non-GMO strain of Bacillus licheniformis. It is used in liquefaction of starch at high temperature.

β-Glucanases: β-Glucanasesare a class of enzymes that hydrolyse β-1,3 and β-1,4 linkages in β-glucans—polysaccharides found in cereals, fungi, and cell walls of yeast and plants. These enzymes are essential in various industries for improving viscosity control, nutrient availability, and processing efficiency.

Cellulases: Cellulases are enzymes that hydrolyse β-1,4-glycosidic bonds in cellulose to release glucose and cello oligosaccharide. Cellulases are a group of hydrolytic enzymes that break down cellulose, the major structural component of plant cell walls, into simpler sugars like glucose.

Lipases: Lipases are hydrolytic enzymes that catalyse the breakdown of triglycerides into glycerol and free fatty acids. These enzymes exhibit broad substrate specificity and operate effectively at oil–water interfaces, making them valuable in industries that deal with fats and oils. Lipases also support esterification and transesterification reactions, expanding their utility into biosynthesis and green chemistry.

Mannanase: Mannanase is a hydrolytic enzyme that specifically breaks down mannans, a group of complex polysaccharides found abundantly in plant cell walls, especially in legumes, palm kernel, guar gum, and copra meal.Classified primarily as endo-β-1,4-mannanase, it cleaves the internal β-1,4-mannosidic linkages in the backbone of mannans, glucomannans, and galactomannans.

This enzyme plays a vital role in various industries by improving process efficiency, enhancing nutrient availability, and reducing anti-nutritional factors in feed and food matrices. Its use contributes to clean-label, sustainable processing solutions.
