The process developed by CIMV is a world premiere for the manufacture of whitened paper pulp, sulfur free linear lignins and xylose syrup from cereal straw and other fibre plants..
Indeed, this new technology allows the separation without degradation of the three main components of the vegetable matter which are the cellulose, the hemicelluloses and the lignins. It is about a vegetable refinery working on the model of an oil refinery..
The organic acids are then recycled by evaporation from the organic solution. The remaining syrup is treated with water to precipitate lignins which is after easily separated.
The lignins showsa totally new simple linear structure which reacts in particular with a lot of monomers towards new polymers and composites.
Xylose can be use to produce alcohol, xylitol, surfactants, additive for animal feeding, furfurol and derivatives, etc…
The CIMV process is a totally non-polluting technology and can work with all fiber plants like rice straw, sugar cane bagasse, sweet and paper sorghum, hemp, wood, etc..
The balance of the marketable products by ton of raw material handled is very superior to all the biomass transformation technologies existing at present, in the world. The three products, cellulose, lignins, and xylose coming from hemicelluloses have identified markets and are at once marketable. It is a perfectly clean technology which works very well at pilot scale.
The industrial development leads by CIMV with Champagne-Cereales as local partner is now on the way.
The first factory will open in Loisy-sur-Marne, near Chalons-en-Champagne in september 2009.
We present here the main scientific and industrial results and assessments of this new sustainable refining process and our concept of the future of the agrichemistry which becomes a very close reality through our technology
