With the increasing demand for paper products, coupled with a need to care for our resources, recycled paper has received a more prominent place in paper production. The presence of ink from printed material and other contaminants gives the pulp a distinctive gray color which is partially washed or floated away in the deinking process.
Novozymes offers a range of solutions which provides recycling mills with effective means to liberate ink. The application of enzymes directly leads to better paper quality: While the brightness level goes up, the residual dirt level goes down. Saving on bleaching chemicals also means milder process conditions and an accentuated sustainable profile.
