Ionic liquids are capable of dissolving lignocellulosic biomass. Examples | Ionic liquids are capable of dissolving lignocellulosic biomass. Examples include corn stalks, rice straw, bagasse, pine wood, and spruce wood.<ref name=":0" /> Next to lignocellulosic biomass, lignin streams can be dissolved for further processing. | ||

Ionic liquids have been shown to dissolve lignin or cellulose, which can decrease its crystalinity and therefore make 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.<ref name=":0" /> | Ionic liquids have been shown to dissolve lignin or cellulose, which can decrease its crystalinity and therefore make it more accessible for further processing.
