As described the high functionality polyols prepared according to recycling method of waste of the present invention by recycling waste polyester, waste polyamide, and waste polyurethane used with the animal and vegetable oils that include the waste edible oil used with the waste polymer are polymerized to facilitate the reaction to convert the double combination double bond of unsaturated fatty acid of fatty ingredients is converted with the conjugate double bond to introduce the Diels-Alder reaction to improve the reactivity to form the sound combination in chemical structure. Therefore, the final product of polyurethane may be prevented the separate leaching phenomenon of fatty and fatty oil the polyols, polyurethanes, and polyurethane forms prepared according to recycling method of waste of the present invention can be employed as industrially useful materials to prepare the polyurethane and polyurethaneforms having excellent mechanical and chemical properties to utilize as the useful material for environment-friendly and economic advantages.
