Abstract
The research and development of the eco-car are advancing rapidly. On the other hand, only little information about merits to environment by the recycling of the car can be obtain. Particularly, the merits are not understood well when plastic parts are recycled. In this study, the LCA of the compact car was studied as a case study. The amount of CO2generated in life cycle of a car was calculated. A lot amount of CO2 generated by the combustion of fuel in traveling was estimated as compared with stage of car production. The reduction of CO2 by mechanical recycling of ferrous metal and aluminum parts was a lot due to weight of parts. It is difficult to decrease CO2 by thermal recovery using plastics waste. It had been found that a little CO2 can be decreased by reduction of manufacturing of virgin plastics by mechanical recycling of plastics.
