Abstract Black liquor is obtained as a by-product of the pulping process, which is used to convert biomass into pulp by
removing lignin, hemicelluloses and other extractives from wood to free cellulose fibers. Lignin represents a major
constituent in black liquor, with quantities varying from 20% to 30%, of which a very low share is used for manufacturing value-added products, while the rest is mainly burned for energy purposes, thus underestimating its
great potential as a raw material. Therefore, it is essential to establish new isolation and extraction methods to
increase lignin valorization in the development of bio-based chemicals. The aim… More >
