Wood and non-wood pulp are produced using several different processes, which include both mechanical and chemical methods. A combination of these methods and thermal treatment is often employed to separate raw wood fibers and produce usable pulp. Each of these methods has an associated bleaching process for decreasing the color of the pulp, making it brighter and whiter. Due to an adverse environmental effect, elemental chlorine-free (ECF) bleaching using chlorine dioxide and totally chlorine-free (TCF) bleaching using hydrogen peroxide or ozone are preferable alternatives to elemental chlorine bleaching. ECF bleaching is the worldwide bleaching standard despite TCF being 100% chlorine free. As a core component of Best Available Technique (BAT) for production of pulp, paper and board, ECF bleaching will likely continue to dominate.
