Recycling rule worth knowing

Remove caps and lids from plastic bottles before recycling.

Caps are often a different type of plastic that causes contamination if mixed with the bottle material. Metal screw-top lids on glass jars are the exception and those can stay on.

Example: Milk bottles, shampoo bottles, soft drink bottles: pop the cap off first.

Frequently asked questions

What do I do with old electronics?

E-waste (phones, laptops, cables, printers) should never go in any kerbside bin. Most councils have e-waste drop-off points at transfer stations, and some libraries and community centres also accept small items. Check your council's website.

What happens if I miss bin night?

Recycling and garden organics are collected fortnightly in many councils, so a missed night can mean waiting two weeks. Some councils let you report an overflowing bin for a special collection. Check your council's website for their missed collection process.

Can I recycle pizza boxes?

A clean, dry pizza box is recyclable. If the base is soaked with grease and cheese, tear off and recycle the clean lid, and put the greasy part in general waste. Oil contaminates the paper recycling process.

Quick tips for bin night

  • The lid has to close. An overflowing bin with the lid propped open often gets skipped, or spills down the street. If it won't shut, it won't go.
  • Break down those boxes. Overfilling the recycling bin means the lid won't close. Lids need to close for collection. Break down the boxes and save yourself the drama.
  • Check your bin before bin night. Bin night is not the time to discover your bin is still full from last fortnight. A quick check the day before saves you a very long fortnight.
