A workshop titled, Mercury in Products, Processes, Waste and the Environment: Eliminating, Reducing and Managing Risks from Non-combustion Sources, was held on March 22-23, 2000, in Baltimore, Maryland. To facilitate discussions of these issues, the workshop combined a series of presentations at plenary sessions, moderated technical sessions and panel discussions. The topics of these presentations focused on treatment and disposal technologies, stockpile management, and prevention, collection and elimination programs. Presenters were from U.S. Environmental Protection Agency (USEPA), Department of Energy (DOE), state agencies, industry, academia, technology developers, equipment manufacturers, consulting firms, international representatives. The presentations were followed by two panel discussions: the first addressed treatment and disposal of mercury-contaminated wastes and the second addressed prevention, collection, and elimination issues. This report provides a discussion of the overarching issues in mercury treatment, disposal, prevention, collection, and elimination, and a summary of the panel discussions that took place at the close of the workshop.
