Patterns to be processed in the deposit and recycling stages of the life cycle of automotive parts were identified. New LCA software for automotive parts was developed by creating an algorithm to calculate the environmental load for each of the various patterns found. The software was tested in terms of its ability to calculate the amount of CO_2 discharged in a bumper recycling system and results were confirmed to be equivalent to those calculated using a process analysis method. To estimate the effect of mechanical recycling, the software was applied to the LCA of rubber parts and calculated the amount of CO_2 dischargtd in patterns of deposit and recycling stage. Results showed that mechanical recycling has an ability to be effective in reducing the amount of CO_2 discharged in life cycle and to be so, it is very important to improve the quality of the recycled material and reduce the amount of CO_2 discharged in collecting process itself.
