“…Kraft pulping, which uses sodium hydroxide and sodium sulfide, is the predominant industrial process to fractionate lignocellulose into cellulose, hemicellulose, and lignin . Removing lignin from the recovery process at a pulp mill is economically attractive because it can increase pulp throughput and create a new revenue stream . Commercial technologies have emerged to precipitate lignin from black liquor by using acids or carbon dioxide, with the LignoBoost process as one of the predominant technologies .…”

“…However, intensive studies are solving the solvent issue through testing and optimizing various solvents with multiple industrial lignins. [ 1,26,27 ] In addition, in‐depth discussion of scalability can be found from literatures. [ 8,28–30 ] These works demonstrate potentials of industrial‐scale production of lignin‐based polymers as a low‐cost renewable resource with high economic value.…”

“…They identified hexamethylenediamine, diethanolamine, 1-methyl piperazine, and morpholine as the best solvents for this process. 177 Another drawback of Organosolv is that, if autocatalyzed, only hardwood provides pulps with acceptable quality and high yields. 178,143 During Organosolv pulping, condensation and ethoxylation reactions as well as excessive aryl ether cleavage might take place, thus resulting in a biopolymer with undesired structural modifications.…”
