Kraft pulping is a chemical process used to convert wood into pulp, which is then used to make paper. In this method, wood chips are cooked in a mixture of sodium hydroxide and sodium sulfide, breaking down the lignin that binds the cellulose fibers together. This results in a stronger pulp compared to other methods. The Kraft process is known for its efficiency and ability to produce high-quality pulp. It also allows for the recovery of chemicals used in the process, making it more environmentally friendly. The pulp produced can be bleached to create white paper or used in its natural brown state.
