Automobiles that are properly disposed under the automobile recycle law are further desired with enhancement in recycling. Especially enhancing reuse which lay in the superordinate concept of recycle, or in other words, promoting the spread of recycled parts is necessary. In this paper, we researched about the present usage of recycle parts among auto-repair shops, and from the results, effect of using recycled parts were evaluated from the environmental and economic point of view. 12 parts were our subject of observation, and by comparing automobiles that use these parts as a recycled part and as a new part, we were able to show a reduction of 821kg of CO_2 and 59 kg of ASR per automobile. Also, from the economical point of view, 24 thousand yen were reduced from a 100 thousand yen repair. By applying these analyzed results, we proposed a method in which to enhance the usage of recycled parts in auto-repair shops.
