You made the switch to energy efficient CFL bulbs. It seems that they last forever∑but when the light does finally go out what should you do? Recycle! Most CFL bulbs with the Energy Star logo have a two-year warranty. Once it’s time to recycle don’t just throw it into your household garbage can where it may leak mercury into whatever landfill it find its way to. Place the CFL in a sealed plastic bag. Check with the City Of Toronto for your local Household Hazardous Waste (HHW) Collection Centre. Home Depot, RONA and some IKEA stores offer CFL drop off programs.
