About the Computer Display Project
The University of Tennessee (UT) Center for Clean Products and Clean Technologies conducted the Life-Cycle Assessment (LCA) and streamlined Cleaner Technologies Substitutes Assessment (CTSA), in voluntary partnership with the Electronic Industries Alliance (EIA), individual original equipment and component manufacturers, EPA risk assessment experts, and other interested parties. The project focused on display technologies that can perform standard applications on 15-inch to 17-inch desktop computer monitors.
The LCA evaluated the full life-cycle of the products, from materials acquisition to manufacturing, use, and final disposition, and identified the life-cycle stages, processes, and/or materials that contribute to the environmental impacts of the products. The LCA impact categories that were considered include: resource consumption, energy use, water use, landfill space use (hazardous and non-hazardous), global warming, ozone depletion, photochemical smog, acidification, air quality (particulates), water eutrophication, water quality, human health toxicity (occupational and public), ecotoxicity (aquatic and terrestrial), and aesthetics (odor). Selected product materials were also assessed further in a streamlined CTSA, which characterized some of the more specific human health and environmental toxicity impacts associated with the product systems, and summarized performance and cost information for the display technologies.
The LCA and CTSA information can be used to identify opportunities for product improvement that will reduce potential adverse environmental impacts and costs. It will also help the U.S. electronics industry continue to meet the demands of extended product responsibility that are growing in the global marketplace.
