Mercury Switch Initiative

Mercury switches are small metal capsules, often called "bullets" that contain approximately 1 gram of mercury each. They are generally located inside automobile trunk and hood convenience light fixtures, which they cause to operate. mercury switch If switches are not removed prior to vehicle crushing, their mercury is vented to the atmosphere as an air pollutant during the smelting process where it eventually falls back to the earth, enters the food chain and is consumed by animals and humans. Starting in 2003, about 30 of New Hampshire's 200 automobile salvage facilities voluntarily collected mercury switches and turned them over to the NH Pollution Prevention Program, which paid for their recycling.

From 2003-2006, the New Hampshire Pollution Prevention Program collected and recycled about 5,700 mercury switches which equals 11 pounds of mercury. In 2007, New Hampshire joined the National Vehicle Mercury Switch Recycling Program; thus ending the voluntary program.

National Vehicle Mercury Switch Recycling Program (NVMSRP)

In August 2006, representatives of the auto industry, scrap and steel industry, auto dismantlers, EPA, state agencies and environmental groups formed the NVMSRP. The program was created to promote mercury switch recycling on a national basis. Unlike New Hampshire's voluntary program, NVMSRP provides salvage facilities a "bounty" of $1 per mercury switch and $3 for ABS assembly until the program's $4 million fund has been depleted. New Hampshire facilities were allowed to begin participation in January, 2007 when a letter was sent to all New Hampshire auto recyclers explaining the process in detail Adobe Acrobat Reader Symbol.
