Analysis of Automotive Parts Remanufacturing Process and Estimation of GHG Reductions

(Starter, Alternator, Compressor Case Study)

Abstract

To contribute to a sustainable society, it is imperative to mitigate the negative environmental impacts. Reducing greenhouse gas (GHG) emissions, resource consumption, and waste generation is essential. As such, extending the lifespan of products through reuse is crucial. In the automotive industry, leveraging recycled parts, especially remanufactured components, offers a promising avenue toward sustainability. However, the environmental benefits of utilizing remanufactured parts remain unclear. This study investigates and analyzes the remanufacturing process of automotive starters, alternators, and compressors. A life cycle assessment (LCA) is conducted to evaluate the environmental load from material procurement to the manufacturing of remanufactured parts. By comparing the GHG emissions associated with new and remanufactured parts, we quantify the GHG emissions reduction potential of using remanufactured components. Furthermore, we develop an estimation equation for the GHG emissions reduction effect based on vehicle engine displacement, weight, and the calculated GHG reduction benefits. In this study, 19 types of parts were investigated and evaluated, including six types of starters and alternators, and seven types of compressors.
