| Feedstock: | Lignocellulosic biowaste |
| Product: | Lignin |
Ionic liquids are organic salts that are liquid at room temperature. Because they are salts, they show no volatility. Moreover, they show a high thermal stability as well. Both properties allows them to be used as green solvents and as and alternative to volatile organic compounds. These properties are useful in the pre-treatment of lignocellulosic material by dissolving the material and separating the lignin.[1] Lignin streams can also be dissolved to allow for further processing.
Feedstock
Origin and composition
Ionic liquids are capable of dissolving lignocellulosic biomass. Examples for biomass include corn stalks, rice straw, bagasse, pine wood, and spruce wood.[1] Next to lignocellulosic biomass, lignin streams can be dissolved for further processing.
Pre-treatment
Process and technologies
Ionic liquids have been shown to dissolve lignin or cellulose, because it can decrease the crystallinity and therefore makes it more accessible for further processing. Moreover, a full dissolution of lignocellulosic biomass can be used to extract the lignin. The technology can also be combined with hydrolysis to make the cellulose available as sugars for further processing.[1] Cellulose can be recovered from the solution by the addition of water, ethanol, or acetone, while the ionic liquid can be recovered by pervaporation, reverse osmosis, salting out, or ionic exchange.[2]
Product
The final product of the process depends on the exact combination of technologies. Generally, a large part of the lignin can be extracted from lignocellulosic material. Depending on the process properties it could also be that cellulose is more easily available for further processing.
Post-treatment
There are no post-treatment technologies known at the moment.

After the LightFibre project showed that kraft lignin and cellulose can be dissolved in an ionic liquid and then wet-spun, the ConCarb project was started to convert lignin and cellulose into carbon fibers, which can be used in light weight composites.[3]
