Tall oil is the third largest chemical by-product in a kraft mill after lignin and hemicellulose; the yield of crude tall oil from the process is in the range of 30–50 kg / ton pulp. [4] It may contribute to 1.0–1.5% of the mill's revenue if not used internally. [citation needed]

Most modern mills use chips rather than logs and ridged metal discs called refiner plates instead of grindstones.
