Novel Starch Saving Program Improves Sustainability in Board Manufacturing through the Reuse of Recycled Fiber Starch, PaperCon2017
The fiber stream raw materials utilized to manufacture recycled paper and board contain a significant amount of starch. Due to microbial activity, process waters in paper mills utilizing recycled fiber usually contain high amounts of starch-degrading amylase enzymes. This usually results in degradation of most of the starch before recycled fiber enters the paper machine, thus potentially increasing COD in waste waters, pH reductions, and higher conductivity due to calcium carbonate dissolution.
