Abstract:
1. An integrated process to produce fuel ethanol and biodiesel from cellulose comprising: providing a raw cellulose stream to one or more containers selected from the group consisting of a vat, a bioreactor, and a tank by mixing a waste cellulose stream and an algae cellulose stream; hydrolyzing the raw cellulose stream to form a hydrolyzed cellulose stream by reacting the raw cellulose stream with one or more fungi from the phylum Neocallimastigomycota; liquefying the hydrolyzed cellulose stream to form a sugars stream; separating the sugars stream to form a xylitol stream and a separated sugars stream; fermenting the separated sugars stream to form a raw ethanol stream by reacting the separated sugars stream with a yeast feed in at least one fermenter; separating the raw ethanol stream to form a fuel ethanol stream; producing an algae stream by reacting the xylitol stream with algae in at least one algae bioreactor; and reacting the algae stream in at least one biodiesel reactor to produce the algae cellulose stream and a biodiesel stream; and recovering the fuel ethanol and the biodiesel from their respective streams.
