Nanotechnology is affecting all industries and paper manufacturing is no exception.
In Brazil, the company Suzano that manages 3000 acres of timberland worked with Israel based CBD Technologies to speed up the growth of Eucalyptus trees. Genetically engineered trees reached a height of 20 meters, at which they are cut for paper making, in three years instead of the standard seven years.
Work is also on to understand the characteristics of fiber and mineral content of paper at micro and nano levels. A clear understanding can improve paper quality, reduce production cost and even improve environmental protection by replacing fiber with minerals in paper.
Nanoparticle driven paper machines are reportedly in use, and have led to improvements in the paper-making process. Better retention and drainage in these machines lead to fewer breaks and higher productivity, according to reports.
Nanotechnology has also helped with the wear resistance, impact toughness and surface finish of roll covers leading to lower maintenance costs and better paper quality.
Other benefits provided by use of nanotechnology include better fillers and pigments, and anti-microbial packaging paper for the food industry.
