Abstract
Method for producing ethanol from solid citrus waste by reducing the concentration of limonene in citrus waste to allow fermentation. In one embodiment ground solid citrus waste is partially hydrolyzed and pasteurized by heating using a jet cooker and then injected into a flash tank to remove limonene. The heated citrus waste is then cooled, hydrolyzed with enzymes and fermented to ethanol. The remaining solids and liquids may be processed further to yield other byproducts. More particularly, the solids may be dried and pressed for use in cattle feed and the liquids may be further fermented or processed to yield additional ethanol, acetate, galacturonic acid monomers and polymers, five carbon sugars and other products.
