The remanufacturing industry is rapidly becoming a source of economic growth and environmental benefit. In the past, researchers have presented cost and energy savings due to remanufacturing a variety of products, largely based on the results of industry-wide surveys. However, little or no effort has focused on the life cycle assessment of remanufacturing. In fact, no study has performed a life cycle assessment of engine components, comparing the original component manufacture with remanufactured components. In this paper, a comparison of the original manufacture and remanufacture of components from a typical Caterpillar diesel engine is described. The “gate-to-gate” analysis considers components that represent a majority of the engine assembly by weight. The comparison is made in two measures of environmental performance: energy and material usage.
