Pulp and Paper Technology is a specialized field of applied science and engineering that encompasses the methods and processes used to produce pulp, paper, and paperboard from fibrous raw materials such as wood, recycled paper, or other plant-based sources. As a branch of materials science, it focuses on the chemical and mechanical processes required to separate cellulose fibers from their source and then reform them into sheets with specific, engineered properties like strength, brightness, and absorbency. The discipline applies principles of chemistry, physics, and engineering to optimize every stage of production, from raw material handling and pulping to papermaking, finishing, and recycling.
