Abstract Scope The end-of-life waste management of cathode ray tube (CRT) funnel glass is a concern due to the high lead content (22%) within the glass. Five waste management options are evaluated from environmental and economic standpoints: hazardous waste landfill, municipal waste landfill, pyrometallurgy, closed-loop recycling, and hydrometallurgy. Two life-cycle assessment (LCA) methodologies: CML2001 and Eco-Indicator 99, are utilized. Economic feasibilities are analyzed using technical cost modeling (TCM). Discarded CRT funnel glass transportation has a significant effect on both the LCA and TCM results. Overall, pyrometallurgy appears to be the most environmentally friendly and economical waste management option. However, the hydrometallurgy option represents the lowest human health impact due to minimized lead emissions. This option also has greater opportunity for process improvement and is more geographically flexible including the potential to be executed on-site, which allows this novel option the opportunity to become more competitive than the pyrometallurgy option if properly implemented.
