The part of waste oil (180, 000200, 000 t) is collected from food service business and food industry and regenerated for reuse.My investigation indicated that most of used frying oil from household finally have been burnt up as garbages after some treatment. For the purpose of the establishment of new recycling system for the collection, regeneration and reuse of used frying oil (about 150, 000 t from household), an adequate volume of used oil with good quality should be secured, other use of collected waste oil should be discovered and the industrial power of oil collection trader and oil regeneration trader shoud be built up.
