Description

Use of biotechnology in pulp bleaching has attracted considerable attention and achieved interesting results in recent years. Enzymes of the bemicellulolytic type, particularly xylan-attacking enzymes, xylanases, are now used in commercial mills for pulp treatment and subsequent incorporation into bleach sequences. There are various reasons for mills to consider the use of bleaching enzymes. Some of the primary reasons are environmental (e.g. reductions in chlorine, chlorine dioxide, and hypochlorite) or economic (decreased chlorine dioxide and/or peroxide requirement), or relate to improved pulp quality (higher brightness ceiling) and improved mill flexibility.
