Lignosulfonates as byproducts

[ketchubl]

Hey I was just wondering if it was possible for Lignosulfonates to be a byproduct of the Kraft process. Someplaces I'v read said only tall oil is a by product, others say lignosulfonates could be extracted from the waste liquor, and some say the two could never exist in the same digester, I know lignosulfonates are a byproduct of the sulfite process, but is it possible in the Kraft process....I need help
