Latest Patents

Widmer's latest patents include a method for producing ethanol from solid citrus waste by reducing the concentration of limonene, which allows for effective fermentation. In this process, ground solid citrus waste is partially hydrolyzed and pasteurized using a jet cooker, followed by injection into a flash tank to remove limonene. The treated citrus waste is then cooled, hydrolyzed with enzymes, and fermented to produce ethanol. The remaining solids and liquids can be further processed to yield valuable byproducts, such as cattle feed and additional ethanol.

Another significant patent involves a method of pretreating citrus waste to break down cell structures and remove inhibitory peel oil components. This method includes reducing the particle size of the citrus waste, preheating it through indirect heating, and then conveying it to a main reactor for further treatment. The resulting pasteurized citrus waste solids can be saccharified with enzymes and fermented to produce ethanol or other products.
