Description
AU-PE89
Xylanase for Improved Bleaching of Paper Pulps
INTRODUCTION
AU-PE89 Xylanase is an enzyme that degrades xylan. AU-PE89 is specific for xylan and does not degrade cellulose. Xylanases produced by different microorganisms operate optimally over a range of pH and temperature. AU-PE89 was developed from a proprietary strain of bacterium for the paper pulp industry. AU-PE89 is particularly suited to the elevated temperatures and alkaline pH of kraft pulps.
TECHNOLOGICAL ADVANTAGE
AU-PE89 acts as a pre-bleaching aid for paper pulps. AU-PE89 has specific advantages in that it is stable and active at the alkaline pH and elevated temperatures typical of kraft pulps.
The main driving factors for acceptance of this technology in pulp mills have been the economic and environmental advantages over chemical bleaching.
AU-PE89 used as a pre-bleaching agent for wood and non-woody pulps can reduce chemical bleach consumption from between 15 to 50%.
BENEFITS OF AU-PE89
Reduce Organochlorines in Wastewater
For mills using active chlorine as a bleaching chemical, AU-PE89 can eliminate or substantially reduce the chemical and environmental load of toxic organochlorines in mill effluent.
Reduce Chemical Costs
For mills using environmentally friendly bleaching agents such as hydrogen peroxide, AU-PE89 can result in a significant cost saving. AU-PE89 has the potential to reduce bleaching chemical by15 to 50%.
Increase Pulp Production Capacity
Pre-bleaching pulps with AU-PE89 allows pulp production capacity to be increased where on-site chlorine dioxide production is a limiting factor.
Higher Pulp Brightness
For a given dosage of bleaching chemical, pre-bleaching with AU-PE89 can give a higher brightness pulp.
