The non-degrading separation of the components of the lignocellulosic biomass, described in all the works done by Prof. Dr. Michel Delmas opened up new horizons for cellulose, hemicelluloses and lignin.


This concept led BioEB to implement the LEEBIO™ process in order to produce Sulfur-free cellulose pulp, Biofuels, Green Hydrogen, Green Methane and even synthetic fuels (SynFuel).


These products are equivalent to those used in our actual commodities, but with the decisive point to be from a renewable source




Cellulose is the world’s production resource for paper pulp and it is also a non-food source of fermentable sugars


Using the LEEBIO™ process, cellulose becomes an innovative carbon source of syngas that can be transformed into Green Hydrogen, Methane or Synthetic Fuel (SynFuel)

Hemicelluloses are extracted in the form of active molasses for the tanning of vegetable proteins in animal feed


The hemicelluloses resulting from the LEEBIO™ process are a non-food source of C5 sugars to produce furan derivatives such as: Xylose, Xylitol, Mannose, furfural, furfuryl alcohol, etc

Lignin is a sulfur-free phenolic biopolymer having exceptional qualities if it is extracted by non-degradative method


Using the LEEBIO™ process, lignin can substitute phenols and polyols in wood glue industry, polyurethane foam, epoxy resins and is also a precursor of low-cost carbon fibers

All products obtained from the LEEBIO process are extracted under exceptional ecological, economic and environmental conditions.

The origin of the process comes from an observation published in 2001 in the article

Formic acid pulping of Rice Straw

In the current energy and environmental context, the LEEBIO™ process allows




to become




which will eventually replace fossil resources and participate in the energy transition
