We develop the CelloFuel Portable Biomass Refinery, for profitably producing bioethanol from sugar beets, sugar cane, sweet sorghum, softwood and waste paper. There are four families of CelloFuel patents that have been granted in the US and around the world, including the EU, Canada, Russia, China and Brazil. We are now licensing these technologies and providing engineering consulting for profitable implementation of these technologies.
CelloFuel technologies produce bioethanol from biomass by infusing reagents under vacuum into biomass. These technologies perform different combinations of enzymatic hydrolysis, dilute acid hydrolysis, fermentation with yeast, alkaline hydrogen peroxide pretreatment, and a patented biomass distillation method. All of these technologies use environmentally friendly reagents, consisting of food-grade enzymes, organic acids (oxalic acid), food-grade yeast, hydrogen peroxide and calcium hydroxide. No sulphuric acid or hydrochloric acid is used, making it possible to discharge wastes into the environment and burn residual biomass to produce energy for distillation. No pressure vessels or harsh chemicals are used.
The CelloFuel solution produces hydrous ethanol at 80% to 95% ABV, with an integrated low-cost distillation column. This can be used to produce potable ethanol, fuel for motors and fuel for cooking.
CelloFuel modules cost-effectively convert sugar-rich biomass to ethanol near the harvest site. Crops are harvested as usual, sugars are converted near the harvest site to hydrous ethanol, and then the remaining biomass is fed to animals, burned for energy, used for anaerobic digestion or applied to land as fertilizer.
One of the major costs of producing ethanol from biomass is the cost of transporting the biomass to the biorefinery. Biomass has low bulk density and is costly to transport. Conversion to ethanol on the farm is an efficient way to reduce transportation costs.
The Cellufuel modules have a very low cost of capital per liter (or gallon) of ethanol produced per year.
CelloFuel modules can produce ethanol from most sugar-rich biomass, including sigar beets, sugar cane, sweet sorghum, softwood and waste paper.
