Around Australia, around 95% of lightbulbs containing mercury are dumped in landfill every year. They are the single largest mercury filled product, but they can be safely recycled to minimise the impact of mercury emissions.
Not all lightbulbs contain toxic substances, but it is still important to dispose of them in an environmentally responsible way.
The most common types of household bulbs:
- Incandescent/halogen (older style)
- Compact fluorescent lamp (CFL)
- Light-emitting diode (LED)
Incandescent/halogen bulbs
Previously, this type of bulb had to be disposed of in your general waste bin as they couldn’t be recycled. Ikea will now take all types of used lightbulbs to be recycled.
Compact fluorescent lamps (CFL)
These bulbs are an environmentally friendly choice because they have a 10,000-hour lifespan (over a year). The problem starts when this bulb reaches the end of its life, as it contains mercury which is classed as Hazardous Household Waste (HHW). These should not be put in your general waste bin or recycling bin.
Light Emitting Diodes (LED)
These are the newest form of energy efficient lights available. They are free of mercury, lead and phosphorus. You should still recycle these bulbs as this will contribute to lowering greenhouse gas emissions.
Remember: never put your lighting waste into your kerbside recycling bin.
Places to recycle used light bulbs include:
Ikea
Perth City Farm, East Perth (CFL bulbs only)
