CFLs– Mercury Concerns & Disposal Information:
Minnesota law says that fluorescent and high-intensity discharge (HID) lights from households may not be placed in the trash, but must be treated as household hazardous waste because they contain mercury. This applies to fluorescent lights of all shapes and sizes, including compact fluorescent lights (CFLs), mercury vapor lights, high-pressure sodium lights; and metal halide lights.Mercury makes fluorescent lights work and cannot be eliminated completely from them. And even though CFLs contain less mercury (5 mg. or less), they - like all other fluorescent lights - must be recycled to keep the mercury out of the environment. The mercury, glass and metal from recycled fluorescent lights can then be reused in other products.
