Rush obtains United States patent.

Rush (San Bernardino, CA) has patented a cellulosic ethanol production process. Implementations may include providing a raw cellulose stream by mixing a waste cellulose feed and an algae cellulose feed and 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. Implementations may include liquefying the hydrolyzed cellulose stream to form a raw sugars stream, separating xylitol from the raw sugars stream and fermenting the sugars stream to form a raw ethanol stream by reacting the sugars stream with a yeast feed in at least one fermenter. Implementations also may include separating ethanol from the raw ethanol, generating 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 feed and a biodiesel stream.
