Chemical Pulping is a fundamental process in papermaking where wood chips are transformed into paper pulp using chemicals. Think of it as a cooking process that breaks down wood into its fiber components, removing unwanted substances like lignin (the natural glue that holds wood together). This is different from mechanical pulping, which uses physical grinding. Chemical pulping creates stronger, higher-quality paper products and is the most common method used in modern paper mills. When you see this term on a resume, it indicates experience with large-scale industrial processes in paper manufacturing.
