Biological bleaching of chemical pulps: a review.
The pulp and paper industry is implementing changes in the bleaching process to minimize the use of chlorine in order to satisfy regulatory and market demands. Biotechnology has a potentially important role to play in providing alternatives to conventional chlorine bleaching of chemical pulps. The current developments in fungal, enzymatic and biomimetic bleaching are reviewed here within an engineering context.
