Abstract In the last decades there has been a rapid evolution of techniques for production of bleached pulp. Much of these processes have been environmentally driven. New techniques have been developed in order to replace chlorine-based reagents in producing bleached pulp. Reducing the environmental impact of pulp production can be attain by using non-pollutant bleaching reagents like oxygen and related compounds. This paper deals with present findings and general trends in environmentally-sound chemical pulp bleaching. Most used environmentally-friendly reactants for pulp bleaching are presented emphasizing their role in a bleaching sequence. Oxygen, hydrogen peroxide, ozone, peracids and polyoxometalates are identified as among the most important reagents that can bleach pulp without affecting the environment. Environmentally-friendly pulp bleaching techniques which include a combination of oxygen, ozone, hydrogen peroxide and other non-chlorine chemicals are presented. Options for mill scale environmentallyfriendly pulp bleaching are included.
