Experimental and computer aided solubility quantification of diverse lignins and performance prediction.

Trial-and-error approaches for lignin applications and new product development is resource intensive. By quantifying the solubility parameters for 45 different lignins encompassing all sources as well as existing commercial scale processes for their recovery, computer-based predictions of lignin solvent-based fractionation and compatibility with various polymers are now possible, paving a pathway for improved chemical analytics and industrial applications.

Quantification and Variability Analysis of Lignin Optical Properties for Colour-Dependent Industrial Applications.

Lignin availability has increased significantly due to the commercialization of several processes for recovery and further development of alternatives for integration into Kraft pulp mills. Also, progress in lignin characterization, understanding of its chemistry as well as processing methods have resulted in the identification of novel lignin-based products and potential derivatives, which can serve as building block chemicals. However, all these have not led to the successful commercialization of lignin-based chemicals and materials.
