The natural resource commonly used in making paper is wood, specifically the fibers sourced from trees. Pulping processes break down wood into cellulose fibers, which are then pressed and dried to form sheets of paper. Various types of trees, including softwoods like pine and hardwoods like eucalyptus, are used depending on the desired paper quality. Recycling and alternative sources, such as agricultural waste or bamboo, are increasingly utilized to reduce environmental impact. The paper industry is significant not only for text and packaging but also for sustainability discussions surrounding forest management and resource conservation.
