NOVELTY - An apparatus comprises: (1) a biogas producer (2) for producing biogas from organic waste; (2) an electricity generator (3) for producing electricity and heat using portion of biogas; (3) a biodiesel producer (1) for converting animal and vegetable fats into biodiesel fuel and glycerol; (4) a unit for providing glycerol from the biodiesel producer to the biogas producer; and (5) a unit to introduce a portion of electricity and heat to the biodiesel producer and the biogas producer.    USE - used for processing organic waste (claimed) such as animal and vegetable fats, e.g. vegetable oil, used oil or unused oil.    ADVANTAGE - The organic-waste composite processing apparatus efficiently converts fats and oils into biodiesel fuel and glycerol. The apparatus is economical and can run with the electric power generated within the system, without using external electricity. The electric power obtained from biogas, and glycerol by-product are utilized efficiently. Valuables such as methane gas can be obtained from the biodiesel fuel. The collection cost of waste edible oil is reduced sharply. Since all the systems are run with natural energy, carbon dioxide is reduced.    DETAILED DESCRIPTION - An organic-waste composite processing apparatus has:    (1) a biogas producer for producing biogas from organic waste;    (2) an electricity generator for producing electricity and heat using at least one portion of the biogas as a fuel;    (3) a biodiesel producer for converting animal and vegetable fats into a biodiesel fuel and glycerol;    (4) a unit for providing glycerol produced as the by-product from the biodiesel producer; and    (5) a unit to introduce at least one portion of electricity and heat to the biodiesel producer and/or biogas producer.    An INDEPENDENT CLAIM is also included for processing organic waste using the organic-waste composite processing apparatus. Animal and vegetable fats are converted into a biodiesel fuel and glycerol with the biodiesel producer. Glycerol is supplied to the biogas producer with organic waste, and biogas is produced. Electricity and heat are produced in the electricity generator using at least one portion of biogas as the fuel. At least one portion of electricity and heat is supplied to the biodiesel producer and/or biogas producer.    DESCRIPTION OF DRAWING(S) - The figure shows the outline systematic diagram of the organic-waste composite processing apparatus. (Drawing includes non-English language text).
