Cellulose brings strength to biomass. It can be identified, for example, by trying to pull the grass lengthwise, which requires quite a bit of force. Hemicellulose brings flexibility to biomass: in the wind, trees sway but need a strong storm to break. Lignin is the adhesive that holds the components together.
All these components, or fractions, have a role in the roadmap towards carbon neutrality and sustainable biomaterials. Currently, cellulose is the most utilized fraction for higher value applications, while hemicellulose and lignin are mainly burned for energy in biorefineries.
Bio2X uses fractionation technology, developed by Fortum's interest company Chempolis, that can extract not only cellulose but also hemicellulose and lignin for high-value products.
