Kraft is the dominant chemical pulping process in Canada. In this process, kraft lignin is incinerated along with back liquor (i.e. spent liquor of pulping) in the recovery cycle of the mill, and thus kraft lignin is generally under-utilized. However, value-added chemicals can be produced from kraft lignin. Recently, Domtar initiated a commercial scale kraft lignin production plant.

硫酸盐法是加拿大占主导地位的化学制浆工艺。在该方法中，硫酸盐木质素在工厂的回收循环中沿着回液（即制浆废液）一起焚烧，因此硫酸盐木质素通常未得到充分利用。然而，可以从硫酸盐木质素生产增值化学品。最近，Domtar启动了一个商业规模的硫酸盐木质素生产工厂。
