| The Company’s core technology is reactive fractionation, a
patented process that separates the major components of biomass and converts
them into fiber, lignin and sugars for others to process into value added
products. The biomass fractionation process includes:
- The unique, continuous pretreatment of biomass;
- The production of a purified cellulose product and separated wash streams
containing the lignin and hemicellulose from biomass; and
- Preparation of the purified cellulose fraction for either enzymatic
conversion into sugar, which can then be converted to ethanol or alternatively
for pulp and paper products.
Biomass (plant matter) is made up
of three major components: cellulose, hemicellulose and lignin. Biomass
includes agricultural residues such as corn stalks and wheat straw, wood
residues such as forest thinnings and municipal paper wastes.
A distinguishing feature of the PureVision process is the ability to efficiently
separate (fractionate) biomass into these three main constituents: cellulose,
hemicellulose and lignin. This patented technology, extensively proven at
bench-scale, provides a critical process to effectively convert cellulose
and hemicellulose into sugars in biorefineries. Once the cellulose, hemicellulose
and lignin are separated in the PureVision fractionation process they become
feedstocks for producing a wide range of bio-products for many industries
including but not limited to energy, transportation, agri-business, textiles,
building products, pharmaceuticals, bio-plastics and paper industries. |
