Deep eutectic solvent


Technology Description

A deep eutectic solvent is a liquid mixture of two components that has an unusually low freezing point and have high lignin solubility, which could make them suitable as novel pulping solvents. Their use could have significantly lower energy needs for pulping compared to traditional chemical pulping processes, as they enable pulp production at low temperatures and atmospheric pressure. They function by dissolving wood into lignin, hemicellulose and cellulose.

Relevance for Net Zero

The technology could reduce pulping emissions by 80%. While still at a low TRL, if development proceeds they could provide a good option to reduce emissions and enable the industry to run on an even higher share of biomass (largely paper-industry byproducts).
