Lignin represents a considerable source of renewable and bio-based carbon. Pulping
processes enable lignin, together with all components of the lignocellulosic biomass, to …

The separation of lignin from the black liquor generated during alkaline pulping is reviewed
in this article with an emphasis on chemistry. Based on published accounts, the precipitation …

The Handbook of Membrane Separations: Chemical, Pharmaceutical, and Biotechnological
Applications provides detailed information on membrane separation technologies as they …

This review details the structure of lignin and curates information on the characteristics that
this polymer must have for each specific use. Lignin is a by-product of the pulp and paper …

Membrane technology allows the separation from the black liquor of different lignin fractions
with a specific molecular weight being able to be used in the synthesis of several high value …

The procedure of electrocoagulation is an effective, fast and economic technique for
treatment of black liquor resulting from paper industry. The effect of electrolysis time, current …

The bioeconomy, and in particular, biorefining and bioenergy production, have received
considerable attention in recent years as a shift to renewable bioresources to produce …

This study aimed at the fractionation of lignin by a simple acid precipitation from hardwood
and softwood Kraft black liquors to propose new value-added applications. The precipitation …

Today, there is considerable interest in integrated forest biorefineries which, besides pulp,
produce high-value-added products, such as, polymers and carbon fibres. Lignin is the …

Efficient recovery of valuable materials from by-products of pulping has been a strong asset
to the environmental concern. The objectives of this research were to recovery and …
