Objective:
Approach:
Through collaboration with leading academic groups, industry, and a national laboratory, life cycle inventory data and modules will be developed for the synthesis and use of nanoclays and carbon nanofibres. These modules will be combined with life cycle information at different spatial scales, ranging from equipment to ecosystems, and used to perform multiscale or hybrid LCA of several potential products. Different scenarios for the manufacture, use, end of life, emissions and exposure of typical consumable and durable products, such as automotive body panels and food wrapping film, will be analyzed along with estimates of uncertainty. Thermodynamic LCA will treat industrial and ecological systems as networks of energy flow and combine the features of systems ecology, LCA and systems engineering. The proposed hypotheses will be tested in a statistical sound manner via several case studies.
Progress Summary:
Expected Results:
LCA of nanotechnology is essential for guiding and managing risk in research, development and commercialization while preventing irrational optimism or unfounded fear of this emerging field. However, it presents formidable obstacles since data and knowledge about resource consumption, emissions and their impact are either unknown or not readily available. This work will lay the foundation for LCA of polymer nanocomposites and other emerging technologies. Validation of the first hypothesis will provide useful insight about nano versus traditional technologies while the second hypothesis will provide a proxy for the ecotoxicological impact of the emissions. These hypotheses will be useful for nano and other emerging technologies before detailed emissions data and ecotoxicological studies are available. As more information about manufacturing, emissions and their impact becomes available it will be incorporated in the proposed studies and tool.
