BORINO, our alkaline aqueous solution of sodium borohydride is used to generate sodium dithionite for the bleaching of mechanical pulp. The solution offers an easy and economical way to produce dithionite, which is typically made by mixing Borino, caustic soda, sulphur dioxide and water. Borino can be used also together with sodium bisulphite instead of sulphur dioxide.

BORDITI is a ready-made dithionite solution. Our solution represents an important improvement in mechanical pulp bleaching safety, since the mill does not need to generate dithionite on site.
