abstract

Sustainable manufacturing has become an emerging environmental, economic, societal, and technological challenge to the industry, the academia, and the government entities. Numerous research and development (R&D) efforts have been launched, and many global and domestic efforts have been initiated toward a long-term sustainable world. This paper provides an overview of R&D efforts in the measurement of manufacturing sustainability, based on an intensive literature search. It focuses on sustainability metrics that apply to unit machining processes for discrete part manufacturing. The authors present results from assessing the scope of indicators that exist for sustainability measurement in general, with a quick visit to the taxonomy of manufacturing activities and different classifications of existing SM metrics by unit machining processes. Most metrics at the unit machining level were developed to measure environmental impacts with respect to energy, materials, water, wastes, and air emissions, while a relatively smaller effort was developed to gauge societal or economic impacts. We report on an analysis of energy metrics available for various unit machining processes at the sub-device and sub-unit process level.
