Integration of Life Cycle Inventories Incorporating Manufacturing Unit Processes
Paper i proceeding, 2011
Sustainable manufacturing (SM) concerns the manufacture of products with regard to environmental, social, and economic impacts over the entire life cycle. With a primary focus on environmental concerns, life cycle assessment (LCA) can support SM practices. The life cycle inventory (LCI) is a key phase of LCA, and this paper considers the integration of manufacturing unit processes (MUPs) into system-level LCIs, which requires consideration of process ﬂow diagrams at different levels of abstraction. Furthermore, uncertainty quantiﬁcation is an important compo- nent of LCA interpretation, and this paper proposes a method to synthesize LCIs from the process-level to the system-level that consistently quantiﬁes uncertainty in the inventories. The method can incorporate MUP data derived from measurements and/or modeling and simulation. Further development towards a complete methodology is discussed.
