(587a) Rapid Estimation of Life Cycle Inventories
The approach to developing LCI data is comprised of four efforts. The first effort focuses on Top-Down Data Mining, which collects data for facilities from EPA sources: Chemical Data Reporting (CDR), National Emissions Inventory (NEI), Toxics Release Inventory (TRI), Discharge Monitoring Report (DMR), etc. Steps for application of data mining and subsequent manipulation are illustrated in Cashman et al. . The second effort applies Bottom-Up Simulation, where design and simulation are used to develop energy and material flows of the system. Additional techniques for estimating uncontrolled emissions from chemical processing equipment are then applied to obtain a detailed emission profile for the process . This simulation method is refined by applying pollution controls to update resource use and controlled emissions. The third effort determines the LCI Chemical Lineage, which quickly determines the chemicals involved in an LCA study, defining the lineage of parents and children in the supply chain of a chemical. Finally, the fourth effort is LCI Reconciliation, which, through the combination of methods, aims to produce inventories that are qualitatively and quantitatively better than the individual methods.
