Ambient Temperature Starch/Cellulose Hydrolysis (ATSCH) is a biorefining process acquired and developed by Aemetis. The ATSCH process biorefines renewable feedstocks to produce renewable fuels that replace current petroleum-based products.
In 2008, Aemetis built and commissioned a 9,000-square foot integrated cellulose and starch ethanol commercial demonstration facility in Butte, Montana where Aemetis scientists evaluated a variety of feedstocks to optimize our ATSCH technology.
The Aemetis Biorefinery upgrades existing corn ethanol plants to use our ATSCH enzymes and solid substrate enzyme production process to produce renewable chemicals and fuels at near ambient temperatures while using non-food feedstock. The ATSCH process utilizes consolidated bio processing (CBP) technology to simplify the enzyme pre-treatment and yeast fermentation processes at existing ethanol plants into one step that eliminates the up-front cooking process and reduces water usage.
