Lixea® is developing an innovative biomass fractionation process using low-cost ionic liquids. Currently, our society is heavily relying on the use of crude oil while products are discarded at the end of their lives. We want to change that, which is why we are developing novel chemical processes that enable us to live more sustainably in a clean world.
Our first product is a process that uses waste wood and agricultural by-products and sustainably grown biomass to produce a greener alternative to today’s petrochemical industry while providing unwanted waste materials with a new purpose.
The Lixea Process
It is a novel pretreatment technology for lignocellulosic biomass, offering unprecedented feedstock flexibility.
Different types of biomass, including agricultural residues, energy crops, forestry residues and even waste construction wood, can be used in a one-size-fits-all process.
An inexpensive and recyclable ionic liquid separates the different components of biomass--cellulose and lignin, while by-products as well as heavy metals present in waste wood can be recovered.
What are Ionic Liquids?
Solvents of the future
Ionic liquids are a class of solvents comprised exclusively of ions. Unlike table salt, ionic liquids melt at temperatures below 100°C and some are liquid at and below room temperature.
They have very low vapour pressure, which makes them safe to handle in an open atmosphere and easily recyclable. Many ionic liquids however have prohibitively high production costs, which has often hindered their industrial application. This is why our team from Imperial College London has specially designed ionic liquids to be inexpensive.
At Lixea, we use ionic liquids which are easily synthesised from bulk chemicals, thermally stable and will cost no more than traditional organic solvents.
As we are preparing for the pilot scale, we are interested in finding new feedstocks and new applications for our products.
One size does fit all!
The BioFlex process is effective on a range of biomass types, including hardwoods and softwoods as well as heavy metal contaminated mixed waste wood. What is more, most feedstocks can be treated under identical conditions, offering unprecedented flexibility. We are keen to validate our process with as many wood types as possible, with a particular interest in material that would otherwise be landfilled or incinerated.

Feeding a sustainable chemical industry
The main products from the BioFlex process are cellulose and lignin. Our cellulose has a very low hemicellulose content and is of high crystallinity. BioFlex lignin is virtually carbohydrate-free and has a nice smell. By-products, such as furfural and acetic acid, both widely used in the chemical industry, can be isolated also.
