Processes for producing ethanol from citrus waste by reducing the concentration of limonene in citrus waste to allow fermentation are disclosed. In one embodiment a slurry of ground citrus waste 1 is partially hydrolyzed by heating using a jet cooker 2 and then injected into a flash tank 4 to remove limonene 5. The heated citrus waste is then cooled, hydrolyzed with enzymes and fermented to ethanol. An alternative method of limonene removal uses enzymatic hydrolysis followed by centrifugation 27 to separate sugar-containing liquid from residual citrus waste solids containing limonene. Sugars are fermented and ethanol is distilled from the fermented mixture / beer. 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.
