From Pulp and Paper International 2014
In the view of the elevated demand for the use of recycled materials from the paper mills, the recycling frequency of the recycled fiber has been greatly increased, resulting in reduced wastepaper quality and increased fiber fines in the process. Coupled with the limitation of fresh water consumption, the papermaking systems of most paper mills have become closed and more complicated.
Buckman developed a new enzymatic technology specific to packaging grades, and it is applicable for various kinds of wastepaper materials. This new technology is highly effective in improving pulp drainage, increasing machine speeds and paper strength properties.
