ENZYMES FOR PULP AND PAPER
Enzyme have the potential to increase the quality and supply of feed stock for pulp
and paper, reduce manufacturing cost and create novel high value products. Novel
enzyme technology can reduce environmental problems and alter fibre properties
Today enzymes are used for bleaching, Refining, De-inking and increasing the
freeness of pulp in paper industries.
AKSA-R :
Refining Enzyme
The main objectives of stock preparation refining are:
- To increase the flexibility of cell wall.
- To promote increased contact area.
- To fibrillate the external surface of the fibre.
- To further promote the formation of hydrogen bonds and increase the total surface area available for bonding.
Refining enzymes improve the efficiency of refining and decrease the consumption
of energy. The use of refining enzyme helps to strengthen fibre while helping
achieve a higher freeness.
AKSA-DK :
Deinking Enzyme
Enzymatic Deinking of waste paper and paper products has generated considerable
interest in pulp and paper industry. One of the main applications of this enzyme is
to remove print from recycled fibres. More than 70% of MOW paper consists of
uncoated papers that are printed with copy and laser printer toners. These are
often difficult to deink by conventional Alkaline deinking process.
AKSA –DK is particularly effective in facilitating the removal of toners from
effective waste toners and decreasing the interaction of toner and ink particles with
fibre.
AKSA-DR :
Drainage Enzyme
The application of this enzyme after refining:
- Increases the drainage of recycled paper, allowing the paper machines to run
faster.
- Selectively digests the smaller fibre fragments of the pulp.
