The Paper Industry in India is one of the dominant industrial sectors with a rich history, starting from the 18th century with the establishment of the first machine-based mill. The raw material used for paper manufacturing in India is different, with wood fibre as the primary material. All the raw materials are mostly procured from agro and forestry farming. The wood fibre is converted into wood pulp, a spongy mass-produced by breaking down the cellulosic material by adding additives. The wood pulp is subjected to further treatment and mechanical processes to produce paper. The raw material used for paper manufacturing in India is now slowly shifting from heavy reliance on wood fibre to recycling waste and agro-waste. 

History Of Paper Technology In India

The history of paper production in India can be traced back to the 12th century. The Chinese were the first to make papers, and the technology eventually spread to Samarkand. This paper technology reached India through artisans from Samarkand. Writing material was available in ancient India in the form of stone, metal, shells, palm leaves, wooden boards, birchbark, etc. 

The first industry for manufacturing paper was established in Kashmir in around 1417–67 AD by Sultan Zainul Abedin. The ruler was held hostage in Samarkand, and upon returning to Kashmir, he brought along artisans skilled at making paper. The raw material used for paper manufacturing in India in the olden times was restricted to forest waste and the production of wood pulp. The history indicates that the main tools used by artisans during the 14th century were a hammer, screen, teak-wood frame, date palm brush, and polishing stone. 

What Are The Raw Materials Used For Paper Manufacturing In India?

The papermaking industry uses many raw materials, out of which wood fibre is the primary resource. The paper pulp is obtained from wood by breaking down the cellulose fibre content to produce paper. The Indian papermaking industry is vast, yet it produces only 5% of the world’s total. As per the Indian Paper Mills Association, the annual turnover of INR 700 billion provides over 0.5 million individuals direct employment. 

Here are some of the raw materials used for paper manufacturing in India:

• Wood Pulp is the most common raw material, majorly obtained from hardwood and softwood trees. It is the most significant raw material contributing to 90% of manufactured paper. It is obtained by the chemical breakdown of the lignocellulosic fibrous material from the wood fibre, forming a soft spongy mass. Pulp is used for making paper used in newspapers, toilet papers, tissues, etc. The wood fibre is obtained from harvested plants. 
• Bamboo is an efficient and sustainable raw material used for paper manufacturing in India due to its advantage of quick regeneration and high fibre content. Nearly 2.4 tonnes of bamboo is used for producing one tonne of paper. 
• Different types of grasses are used for paper manufacturing, including sorghum stalks, wheat straw, reeds, bagasse, Sabai grass etc. Sabai grass was used before bamboo due to its long fibre, but now its use is limited. Bagasse is the fibrous part of sugarcane stalk and one of the raw materials for paper. 
• Recycled waste: The waste paper fibre is also used to produce paper. The recycled waste is used as raw material for producing a significant percentage of paper. Recycled paper pulp is a crucial raw material used for paper manufacturing. The ink is separated by the deinking process from recycled paper pulp and mixed with new pulp for paper production. 

How Is Paper Made From Its Raw Material?

After the raw material is obtained, it requires further processing to manufacture the paper. 

Here are the steps to understand how paper is made:

• Production of Pulp: The first step in the production of paper is the preparation of the pulp. Wood fibre is converted into pulp, a spongy mass, through the addition of chemicals that break down the lignocellulosic material. Both mechanical and chemical pulping methods are used. Either wood or recycled paper pulp is used. 
• After the pulp production, the water is removed from the fibre solution, which helps produce a thin, uniform layer of paper. 
• As the whiteness of the paper is important, once it is removed from the water, it goes through the process of bleaching, refining, and colouring the fibre. The process of beating and refining the pulp increases the surface area of the fibre, improving its mechanical properties.
• The pulp mat is passed through nip rollers, squeezing out the remaining water due to pressure. After sizing, paper is passed through heated drying cylinders to dry and lose the remaining water.
• After manufacturing the paper sheets, it is passed through smooth rollers that give them a smooth and glossy appearance.

Conclusion

Paper is used for educational and academic purposes, tissue paper, packaging, etc. The most common raw material used for the generation of the maximum percentage of paper is the wood fibre obtained from harvesting hardwood and softwood. The other raw material used for paper manufacturing includes recycled paper pulp, bamboo, grasses, etc.
