Technical lignins can be produced with many different processes, which influence significantly the properties of the resulting lignins. Besides the botanical origin of the lignin (plant species), the chemistry that is taking place during the isolation of these lignins is indeed the main factor that will determine the behaviour of separated lignins in their different fields of application. |
Besides classical processes of lignin separation (Kraft process, Sulphite process, Soda process) that are largely used in the paper industry, multiple new processes have been investigated, but none of them has so far reached industrial application (organosolv processes, various biorefinery processes). |
| The topic contains two main types of papers: lignin production (extraction of the lignin from residues in biomass processes) and lignin modification (improvement of functionalities and molar mass composition for specific purposes). |
An overview report on lignin production is available in the database. Additional information about lignin production processes, including the main new developments for lignin production that are not in the overview report can be found just below. As they come up, other new processes will be described in the Running Update and in the Recent Postings. |
| A general overview on lignin modification can be found in General Information: R. Malherbe, A. Abächerli 2007 pp. 11. Further papers with new developments are continuously appearing in all the sections below. Also fractionation of lignin into several smaller and better defined fractions is an important topic there. |
