The LEEBIO™ process refines all the components of Earth lignocellulosic biomass without generation of polluting effluents and no fossil emissions


Depending on the business model chosen between paper pulp, green hydrogen, synthetic fuels and low-carbon biofuels, the energy required to operate a LEEBIO™ industrial unit is essentially heat (<100°C) that can be generated by renewable resources


LEEBIO™ can integrate existing industrial infrastructures for their decarbonization such as oil refineries, coal-fired power plants, natural gas power plants but also pulp & paper factories.


The versatility of the LEEBIO™ process is one of the key elements for decarbonizing our energies in addition to other renewable energy sources

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 specification of the pulp makes it suitable to be transformed into a sustainable source of paper for packaging, corrugating boards, specialty papers, sacks & wrapping paper, etc. 


Non-wood pulps (cereal straws, miscanthus, palm residues) are a very attracting products and can be easily extracted using the LEEBIO™ process


Moreover, because their silica content is high, it is possible to valorize it for sustainable silica production




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 raw 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.
