Alcohol Fuel

One greenhouse (501 x 156) will be used to house the alcohol fuel production equipment and fish feed equipment. It will be located separately from the aqua — ponic greenhouses. Site preparation has been completed for this greenhouse, as well as water supply and electric transmission lines. The water supply is from a developed artesian well, which will have its capacity expanded. The project will use bakery waste as the feedstock for alcohol since it is so plentiful locally. After packaging is removed, the production of fuel will follow these steps: A) the bakery waste is passed through a standard garden chipper-shredder, B) the shredded bakery waste is mixed with hot water in a tank, C) a liquefication enzyme is added and the mixture is boiled for about 20 minutes — this enzyme prevents the slurry from jelling, D) the mash is cooled to 140°F and a saccharification enzyme is added. It is held at this temperature for another 20 minutes. The saccharification enzyme converts starch to sugar, E) once starch conversion is complete, the mash is cooled to 90°F, adjusted for optimum yeast activity to occur (Ph and brix), and distillers yeast is added. A vapor lock is installed to eliminate contamination of the ferment by airborne putrescent bacteria. CO2 is captured at this stage, F) when yeast activity stops — from 3-5 days — the ferment is filtered to remove solids, and G) the clear liquid beer is now ready for distillation. Once distilled and denatured, it is ready for the microturbine to generate electricity and heat for the greenhouses. The solids that are generated will be mixed with other components, pelletized, and used as the base for fish feed. Packaging is sorted, compressed, and sold as scrap, or used as direct combustibles.
