Chrysalix Technologies is an Imperial College bioeconomy spin-out company developing an innovative biomass fractionation process using low-cost ionic liquids.

Waste wood from construction and demolition typically contains heavy metals from wood preservatives and paints which make the wood non-recyclable. As a result, this unwanted waste is sent to landfill or incineration. This is costly and has negative environmental impacts such as pollution of air, water and soil.

Chrysalix Technologies’ team from Imperial College has developed the BioFlex solvent process which makes use of unwanted waste wood as a very cheap raw material to produce inexpensive and clean chemicals, materials and fuels. The process can condition any type of woody material in a highly effective manner without producing harmful emissions or waste. This allows for a reduction in waste while offering a route to a sustainable and affordable bioeconomy.
