The natural resource commonly used to make paper is wood. Paper production primarily relies on cellulose fibers obtained from plants, with the majority sourced from wood pulp. Trees such as pine, spruce, and eucalyptus are frequently harvested for this purpose due to their cellulose content and growth rates. The wood is processed through mechanical and chemical pulping methods to extract the fibers, which are then dried and formed into sheets. While recycled paper and alternative materials like hemp and agricultural residues are also used in paper-making, wood remains the dominant resource, playing a vital role in the global paper industry.
