The LEEBIO™ process extracts the main constituents of lignocellulosic biomass: cellulose, lignin, hemicelluloses and silica as high-value products

These products are renewable and safe. They can be introduced into industrial sectors without changing the existing technologies  infrastructures



LEECELL™ cellulose is a product and a source of renewable energies


It is an unbleached Paper pulp able to integrate current pulp & paper industries without undesirable effluents


It is a source of fermentable sugars for the production of low-carbon Biofuels


Our innovation is the transformation of this cellulose into a clean synthesis gas able to provide renewable products: Synthetic Fuels & Green Hydrogen



LEELIGNIN™ is a sulfur-free lignin extracted as a brown powder


It is a phenol and polyol products with a well-established structure.


It can substitue phenol and PEG (PolyEthylene Glycol) during the synthesis of phenolic resins, epoxy resins and polyurethanes


Depending on its origin, this lignin can be an excellent low cost carbon fiber precursor, particularly sought after in automotive industries


The LEEBIO™ process guarantees that this lignin is reproducible from the same raw material



LEEXYL™ hemicelluloses are extracted in the form of molasses (or black treacle)


This kind of syrup is rich in oligomeric xylose (up to 70%), proteins and natural elements. Mannose sugar is highly present in softwoods based molasses


This molasses can be used as a strong nutritional and tanning agent in animal nutrition


It is also suitable for the production of Furfural, 2,5-furandicarboxylic acid (2,5 FDCA), 2-methylfuran, Xylitol or biofuels based products



LEESIL™ silica is a white powder obtained by chemical precipitation methods


This renewable silica is interesting to extract from rice straws as starting material


This form of amorphous silica is particularly appreciated in high-tech or medical industries for its reinforcement, adsorption and polishing characteristics, but also in tires
