Nature of Business In addition to its ethanol production capabilities, the Company developed proprietary technology that uses a combination of synthetic biology, metabolic engineering, chemistry and chemical engineering to make isobutanol and hydrocarbon products from isobutanol that can displace petrochemical incumbent products. The Company has been able to genetically engineer yeast, whereby the yeast produces isobutanol from carbohydrates. The Company’s technology converts its renewable isobutanol to alcohol-to-jet (“ATJ”), isooctane, isooctene, and para-xylene (building block for polyester) at its hydrocarbons demonstration plant located at South Hampton Resources located in Silsbee, Texas. In addition the Company’s production facility located in Luverne, Minnesota (the "Luverne Facility") has production capacity of about 20 45 50 3 As of June 30, 2018, Financial Condition .
