Business Waste: Mercury and Mercury-containing Products
Proper Disposal: The "Dental Office Waste" and "King County Limits" Web pages of the King County Industrial Waste Program provide information on complying with county wastewater regulations. See For more information about mercury recycling and disposal, visit
Recycle: Mercury products should be recycled or reclaimed through a facility permitted for this purpose. You can send them directly to a mercury reclaimation facility or hire a broker to ship the waste.

*electrical switches and relays;
*vehicle switches in hood and trunk lights;
*in anti-lock brake systems;
*fluorescent tubes and high intensity discharge lamps;
*dental amalgam; batteries; measuring instruments (barometers, thermometers, etc.);
*some pharmaceuticals; paint produced before 1992; and
