We developed technology based on the best synthetic biology, best classic biology, and best chemical industry production techniques to convert carbohydrates to low carbon chemicals and fuels. Our source of carbon is CO2 in the atmosphere, the GHG itself, captured by plants in the form of carbohydrates. The plants are grown with sustainable growing methods wherever possible, building soil quality and carbon levels. We like to capture the protein produced by the plants, add more from fermentation, and supply it to the feed and food markets. The carbohydrates are separated from the protein and fermented via specially designed yeast to make low cost alcohols like ethanol, isobutanol, and higher alcohols. The alcohols can be sold directly for chemical or fuel use. We especially like to take the alcohols and convert using chemical industry catalytic processes to produce jet fuel, gasoline, polyester, rubber products, as well as specialty chemicals, fine chemicals, and ingredients for flavors and fragrances.
