The LEEBIO™ process extracts the main constituents of lignocellulosic biomass, namely cellulose, lignin, hemicelluloses and silica

These are products of non-fossil origin, renewable and they will be introduced directly into industrial sectors without changing the existing equipment

CELLULOSE – LEECELL™

 

LEECELL™ cellulose is both a product and an energy source for the LEEBIO ™ process.

 

It is extracted from all lignocellulosic residues such as cereal straw, wood residues (sawdust, shavings etc …), bagasse, energy plants, etc …

 

It can be perfectly integrated into the paper industries without generating any pollution.

 

The innovation we offer is its transformation into uncontaminated synthesis gas (Syngas) to provide a choice of: synthetic fuels (Synfuel), green CO2, but also green hydrogen.

LIGNIN – LEELIGNIN™

 

LEELIGNIN ™ is a lignin extracted as a brown powder.

 

It is composed of aliphatic phenolic and OH oligomers with a well-established structure, allowing the substitution weight by weight of phenol and PEG (PolyEthylene Glycol) in the synthesis of phenolic resins, epoxy and polyurethanes.

 

Depending on the starting material, 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 not degraded and that it is reproducible from the same raw material.

HEMICELLULOSES – LEEXYL™

 

LEEXYL ™ hemicelluloses are extracted in the form of molasses.

 

It has a composition rich in oligomeric xylose (up to 70%), proteins and natural elements. When extracted from softwoods, its composition is also rich in Mannose sugar.

 

In its raw state, this molasses has a strong nutritional and tanning power in animal feed.

 

It is also the only non-food source of furan products, suitable for the production of Furfural, 2,5-furandicarboxylic acid (2,5 FDCA), 2-methylfuran, Xylitol or biofuels.

SILICA – LEESIL™

 

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

 

This silica is extracted from LEECELL™ by a non-polluting method.


Its extraction is particularly interesting in the case of the extraction of rice straws.

 

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.
