BIOREFINERY CONCEPT

Based on the oil refining model.

Promote 100% of the non-food Biomass– in Biofuels and/or

Bioproducts.

High feedstocks fexilibility (straw, bagasse, hardwood, etc.).

bio-based products :

BioligninTM,

Cellulose pulp,

C5 sugars syrup.

OTHER PRODUCTS

Silica : can be extracted from wheat and rice straws

Non-sugar fraction : in case of C5 fraction purification,

the remained fraction is used as fertilizer ( contains

minerals,proteins, etc…)
