CFL bulbs should be properly recycled. Home Depot & some ACE Hardware stores accept CFL bulbs for recycling. Each bulb should be placed in a ziplock baggie, to be sure no mercury vapors are released if the bulb gets broken in transport or at the store.
CFL bulbs & Tubes can be taken to the Household Hazardous Waste Site in Naperville.
