Pulp and paper refer to the process of producing paper products from raw materials, primarily wood. The first step involves converting wood into pulp, which is a mixture of cellulose fibers and water. This pulp can be made from various sources, including trees, recycled paper, and agricultural residues. Once the pulp is created, it is processed and dried to form sheets of paper. The paper industry plays a significant role in producing various products, such as books, newspapers, and packaging materials. Sustainable practices, like using recycled materials, are increasingly important in this industry to reduce environmental impact.
