The LEEBio™ process is based on the chemical separation of lignocellulosic residues into cellulose, lignin, hemicelluloses and silica.


This process is non degradative and uses only formic acid (<95°C) at atmospheric pressure.


The consequences of this chemical separation are a very low energy consumption and a high separation efficiency.


LEEBio acronym means Low Extraction Energy of Biomass.
