by Jim Lane (Biofuels Digest) US-based White Dog Labs have developed a new process that eliminates the production of CO2, a potent greenhouse gas, during fermentation and instead shifts the carbon to added ethanol production, boosting fermentation yields by around 50 percent. The by-products are distillers grains, corn oil (if extracted from the grains) and water.
The process can boost acetone production by 60%, all by its onesey, and half the CO2. Add supplementary hydrogen, and you get zero CO2 and a 50-60% percent boost in ethanol production and up to 120% increase if the process is optimized for acetone. READ MORE
