Recycled packaging

Our lignin-based products enhance polymeric strength when used in the production of recycled packaging paper.

They are used in the paper machine size press to partially displace more expensive starch. This not only saves costs, but also enhances the strength of recycled paper and improves machine productivity.

In addition, the use of these products improves sheet appearance by imparting a darker more consistent shade, thereby eliminating the need to add expensive dyes. The products may also reduce dryer energy requirements, resulting in further cost savings.

Le lignosulfonate est un dérivé de la lignine très soluble et un produit issu du procédé de fabrication au bisulfite.

Our lignin is used in a variety of industrial and agricultural areas for various applications.
