The Ministry for the Environment website advises that single-use dry cell batteries (non-rechargeable) of types zinc carbon, zinc chloride and alkaline manganese are not classed as hazardous waste and are acceptable to dispose of in household waste.
The ministry website also has useful information on the disposal of light bulbs. In essence, it says:
"Incandescent lamps (both the old-style tungsten filament and more efficient tungsten halogen ones) and other halogen lamps can be disposed of with household rubbish. Wrap any broken glass in newspaper to prevent injury during handling of the rubbish bags.
"Fluorescent lamps, [including energy-saving], contain small amounts of mercury. While the mercury poses no immediate threat to human health or the environment when the lamps are used, mercury is a toxic substance so these lamps need to be managed properly when they become waste.
You'll need to check with your local authority as disposal options can vary for different regions."
Auckland Council's website advises that energy-saving light bulbs are not acceptable at its transfer or recycling stations. However, the EECA Energywise website suggests that if your local council won't accept these light bulbs for recycling, you can wrap them carefully in a sealed glass or plastic jar and put them in your normal household rubbish, preferably outside.
Confused yet? Can anyone clarify what we should do?
