The LEEBIO™ process refines all components of lignocellulosic biomass without generating atmospheric and terrestrial waste

A LEEBIO™ industrial unit will exclusively use heat from renewable sources

The LEEBIO™ process can integrate existing industrial infrastructures for their decarbonization such as oil refineries, coal or natural gas power plants, but also pulp and paper mills

The versatility and flexibility of the LEEBIO™ process are key elements for decarbonizing our energies in addition to other renewable energies

The LEEBIO ™ process extracts cellulose, hemicelluloses, lignin and silica from any type of lignocellulosic residue with very good yields and a high degree of purity.

Cereal straws and wood residues are examples below

The LEEBIO™ process can develop at least 3 different business models based on the use of cellulose as a sustainable resource: Sulfur-free Cellulose pulp, Hydrogen/CO2 and Synthetic fuels



Cellulose unbleached pulp extracted from the LEEBIO™ process is exempt of non-natural sulfur and have a low Kappa number


This unique pulp specification allows it to be incorporated into existing mills to be transformed into a sustainable source of packaging type paper, corrugated cardboard, specialty papers, paper bags, etc.

Non-ligneous pulps (cereal straw, miscanthus, palm residues) are very attractive products and can be easily extracted by the LEEBIO™ process.

Sustainable silica can also be extracted with high efficiency from silica-rich biomass such as rice straw.



The thermochemical transformation of a sulfur-free cellulose allows the production of a high grade syngas (CO + H2), named Cellulosic Syngas


A very interesting amount of green Hydrogen and green carbon dioxide can be produced and recovered in existing gasification industrial units


Gasification of cellulose is a realistic innovation that reaches the perfect energy balance and syngas purity contrary to direct biomass gasification



Cellulosic syngas will be an interesting source of sustainable fuels commonly named Synthetic Fuels


Sulfur, Nitrogen and Chlorine contaminants are known to disturb the products yield from Fischer-Tropsch (FT) industrial units


They have a negative impact on the profitability of the biomass to liquid fuels business


Cellulosic Syngas is free of these contaminants and it can be easily introduced into FT industrial units to be transformed into fuels such as Sustainable aviation fuels (SAF), Gasoline and Diesel

Based on current market prices, 1 tonne of dry lignocellulosic residues will generate green and high value products, green energies, sustainable fuels and very interesting revenues.

Lignocellulosic biomass producers (farmer, loggers, etc.) and existing industries (pulp & paper, oil, gas, coal, power plant and chemicals) will be at the center of the energy transition by integrating the LEEBIO™ process, atmospheric CO2 and NCCSU™ to their actual business.
