Recycled paper and board contains a significant amount of starch. Due to amylase enzymes in the mill’s process waters this starch usually degrades before recycled fiber even enters a board machine.
Kemira introduces a unique approach and a revolutionary technology that protects both fresh and recycled starch from degradation and improves the starch reuse. By optimizing the retention program on the board machine the non-degraded recycled starch can be retained into fibers giving extra strength and increasing the grammage of the final board product with same fiber usage. Starch reuse also means that the wastewater COD level or odors can be reduced significantly.
