All fluorescent light bulbs contain mercury gas (even the ones with green tips). Many municipalities accept fluorescent bulbs from residents and businesses for free or a small charge. The Center for EcoTechnology offers free disposal guidance to Massachusetts businesses and residents. Contact Sean Pontani at sean.pontani@cetonline.org or 413-586-7350, ext 225. Additional recycling options vary based on the type of bulb:
Compact fluorescent lamps (CFLs) fit in standard screw-type light sockets and are made of a narrow coiled glass tube. They come in a variety of shapes and styles, and can be encased by an outer glass bulb. Free CFL recycling is offered at Aubuchon Hardware stores, Home Depot, Lowes, the Solar Store (Greenfield), Whole Foods, IKEA and Ace Hardware.
Larger fluorescent tubes do not fit in standard screw-type sockets. These include long straight, circular or U-shaped tubes, tanning bed lamps, High Intensity Discharge (HIDs), and neon light tubing. Commercial organizations generating large numbers of bulbs may contract directly with a lamp recycler; licensed mercury recyclers can be found at www.mass.gov/dep/toxics/stypes/flampbiz.
