To establish sustainable manufacturing, it is necessary to evaluate manufacturing quality. We have proposed a new product efficiency indicator; total performance indicator (TPI). In this paper, we try to apply TPI to manufacturing processes. By calculating TPI of each segment process, bottleneck segment process can be clarified. This paper takes ceramic diesel particulate filter as an example. The method quantifies the contribution of each segment process in creating the product value. A segment process which doesn’t contribute much to create value and have large environmental impact, should be improved. By the approach, a designer can evaluate and redesign environmentally benign manufacturing processes.

Keywords: environmental impact, total performance indicator, utility value, DPF, wet jet mill
