Our stand-alone AVAP® (American Value Added Pulping) technology is a patented true fractionation biorefinery process that efficiently fractionates biomass into its primary components, cellulose, hemicelluloses and lignin.
- In the first step biomass is fractionated into its three major components: cellulose, hemicelluloses and lignin.
- In a second step, the hemicellulose fraction is auto-hydrolyzed to sugars using residence time and heat.
- In a parallel second step the cellulose fraction is converted to products. The cellulose that is generated from AVAP® has very low content of lignin and hemicelluloses. It is an ideal feedstock for the production of pure cellulose, nanocellulose or cellulosic glucose.
- The high purity fiber leads to very low cost enzyme dosages to convert the AVAP® cellulose to a clean glucose stream in preparation for downstream conversion to chemicals using biological organisms or chemical catalysis. Lignin is recovered for use in lignin derived products or becomes boiler fuel to produce the energy to run the process.
AVAP Demonstration Plant is located in Thomaston, GA, USA, with a capacity of up to 1 to 3 tons per day biomass feed.
Beginning in April 2015, BioPlus products are being produced for commercial sales at our Thomaston Biorefinery.
The biorefinery supports supply chain alliances with downstream end-users of bio-based sugars, lignin, and cellulose for conversion into renewable, bio-based chemicals, fuels, and materials.
