KRAFT PULP

BROWN FIBRE

If you're a wood chip at Howe Sound and you don't go to newsprint, then you'll start the paper making journey in the Kraft Mill. To begin the process the chips are cooked in a giant pressure cooker called a digester. Wood is basically wood fibres held together by a natural glue called lignin. In order to make kraft pulp, we need to use chemicals to dissolve this lignin so that only the long wood fibres are left. The longer the fibres, the stronger the pulp. The chemicals that are used to do this (sodium hydroxide and sodium sulphide) are called white liquor. After the chips are cooked, they are washed so that the liquor can be recovered and recycled back into the system. These fibres are then bleached white in our Bleach Plant.
