FAQ
Frequently Asked Questions
Yes, essentially. 'Kraft pulp' is the more common industry term for pulp produced by the sulfate process. 'Kraft' is German/Dutch for 'strength'.
They use different cooking chemicals. Sulfate (kraft) uses sodium hydroxide and sodium sulfide, yielding very strong, dark pulp. Sulfite uses sulfurous acid and a bisulfite, yielding a lighter, more easily bleached but weaker pulp.
It is the dominant chemical pulping method globally because it produces the strongest fibers, efficiently uses most wood species (including resinous pines), and allows for chemical recovery and recycling within the mill.
Almost never. It is a highly specialised industrial term. In everyday life, people encounter the end products (paper, cardboard) without needing to know the specific pulping process.
