Huntsman Textile Effects and Genencor, a division of Denmark-based Danisco A/S, today announced the results of a Life Cycle Assessment (LCA) on GENTLE POWER BLEACH ™, a bleaching system introduced into the textile pretreatment market in March 2009. As opposed to conventional bleaching systems, GENTLE POWER BLEACH™ contains unique, first-to-market enzymatic bleaching technology from Genencor, a leading solutions provider in industrial biotechnology.
“Although the cotton pretreatment processesing parameters will differ across the globe, we found a substantial advantage for GENTLE POWER BLEACH™ among each of the many environmental impact categories that we tracked”, says Jon Dettling, US Director for Quantis International, the organization that performed the LCA. “For instance, the LCA concludes that if the relative benefits of GENTLE POWER BLEACH™ were applied to the roughly 26 million tons of cotton produced globally [a 2007-2008 statistic], the savings in freshwater consumption globally could be in the range of 10 trillion litres of water annually, which is more than 1000 litres annually for each person on earth. This result depends strongly on the available information regarding cotton irrigation, but nevertheless illustrates the large potential benefits of the technology. Significant reductions in global greenhouse gas emissions are another benefit of this process. It is estimated that GENTLE POWER BLEACH™ has the potential to reduce global CO2 emissions by 10-30 million metric tonnes annually,” Dettling adds.
“As outlined last year, Genencor is dedicated to delivering innovative industrial biotechnology solutions which foresee the changing needs of our customers. At the same time, we are pushing the envelope to deliver solutions that also significantly contribute to more sustainable business practices,” commented Glenn E. Nedwin, Executive Vice President of the Technical Enzymes business unit at Genencor. “The results of the LCA clearly demonstrate the impact and relevance of enzymatic alternatives to existing technologies for the textile processing industry – reducing water and energy usage while increasing performance – a win/win for the
