Common Types of Mercury-Added Lighting Fluorescent – Linear Tubes – Compact Fluorescents – Exit Signs High Intensity Discharge (HID) – High Pressure Sodium – Metal Halide – Mercury Vapor Neon Lights

How Does Hg in Lamps Get Released? Manufacturing – Especially if hand dosing/liquid mercury used Transportation – Factory to retail to consumer to disposal Installation/storage – Accidental breakage (see ME DEP,MPP studies*) Disposal – In dumpsters, garbage cans, incinerators, landfills Recycling – During crushing, mercury recovery, metal smelting * http://www.mercurypolicy.org/new/documents/Final_Shedding _Light_ALL.pdf * http://www.maine.gov/dep/rwm/homeowner/cflreport.htm

Revised Reference: Summary of supply, trade and demand information on mercury, UNEP, Nov 2006 Note: “Demand” may also be termed “gross consumption,” and is defined as total annual throughput of mercury for each of these sectors. It should be noted that in each of these sectors some recycling takes place, involving the recovery of mercury from products or wastes. Therefore, “net consumption” of mercury in some of these sectors (esp. VCM and chlor-alkali) may be significantly lower than “gross consumption.”
6
Lighting in Global Hg Demand Context Small portion of global Hg demand now Importance will grow over time as other sectors reduce their Hg demand Because of anticipated large growth esp. in CFLs, it’s assumed ongoing reductions in Hg content and improvements in dosing methods will help offset the unit growth Therefore, lamp Hg use projected to be approximately the same (as now) in 2015

Fluorescent Lamp Production in China China largest producer Uses 64 tons of mercury annually 14 tons used in production of compact fluorescent lamps alone

Annual Consumption of Hg in Lamps Estimated at 21 Tons in 2004 Total Annual Consumption = 276 tons
11
Fluorescent Lamp Use & Release in US In 2004, 514 million lamps were generated in US -142 million were from residential use - 372 million came from businesses, government and institutions. More than 670 million fluorescent lamps were sold nationally in 2006 Consumption continues to grow each year Discarded lamps result in tons of mercury emissions to the environment
12
Lamp Recycling in the US 22% of all lamp usage is by users not regulated under federal rules (i.e., household or CESQG small businesses) As a result, only 2% fluorescent lamps from residents recycled (Photo: IKEA collecting at retail) Over 20% of fluorescent light bulbs from businesses, governments and institutions are currently recycled
13
Sustainable Lighting Policy Overview Environmental Goals/Commitments Energy efficiency Waste prevention Toxicity reduction Recycling Sustainable manufacturing Vendor reporting and training
14
Lessons Learned on Hg Content of Lamps Age matters: Modern lamps = lower mercury – Avoid older “preheat” fluorescents and T12s Lamp life does not matter: –Often longest lasting lamps have least Hg Shape matters: Avoid lamps with odd shapes – Circular fluorescents (T9s), U-bent fluorescents sometimes have more Hg Size matters (but not always how you expect) –Avoid odd-sized lamps (e.g., 5- & 7-foot models as well as 6- & 18-inch models) Brand matters: Shop around –Some companies put much more Hg in equivalent lamps
15
Strategies for Reducing Mercury from Lighting Equipment Choose most energy-efficient models – Examples: Super T8s andT5s – Reduces power plant emissions, # of lamps needed – Restrict sales/purchases of inefficient lamps (T12s) Specify long-life lamps (PLUS, XL, LL, XP) Integrate recycling into lamp purchasing Consider innovative technologies (e.g.,LEDs) that don’t contain Hg
16
Specify Low-Toxicity Lamps Require bidders to disclose mercury and lead content of lamps Set mercury caps (best in class) –Europe (RoHS), ENERGY STAR, Canada EcoLogo –CA, NYC, SF, Wal-Mart, Green Guide to Health Care Avoid fixtures/ballasts for high-mercury lamps Give preference for lead-free lamps Make policy commitment to buying least-toxic lamps that meet needs Require lamps to be made with safer dosing
17
Summary/Conclusions Absent Hg content reductions and dosing improvements, Hg use will increase w/expanding use, and negate reductions anticipated in other sectors The movement of production to the developing world heightens NGO concerns over Hg use in this sector Coupled with poor recycling rates, Hg pollution will increase in US and globally THIS IS AN UNACCEPTABLE OUTCOME National stakeholder dialogue will (hopefully) raise awareness for collaboration and action needed to reduce lamp sector Hg both in US and globally
