Oxygen is the basis of the environmentally friendly bleaching processes oxygen delignification and oxygen bleaching. 

Oxygen delignification/bleaching is today a proven bleaching technology and is widely used as a bleaching stage in ECF and TCF processes, especially as a first bleaching stage. It enables a good kappa number reduction while maintaining strength and can be well integrated into the washing cycle during the Kraft process to reduce the water requirement. Furthermore, this process is characterised by its low chemical costs.
