Plastic recycling: it's not by numbers


Does it help to know the symbol with the numbers inside?

The short answer: no.

Many people use the triangular symbol with a number inside to identify what can be recycled in the yellow-lid recycling bin. This symbol is NOT a recycling symbol for kerbside recycling. It is a Plastics Identification (PIN) code or number used by manufacturers and plastics recyclers to distinguish the various types of plastic for reprocessing.

What plastics can be recycled in the yellow-lid bin?

Ask yourself these questions:

  • Is it a container?
    Plastic containers that are rigid or semi-rigid can be recycled.

    A helpful hint for deciding if it is semi-rigid is if it generally retains its 3 dimensional shape when crumpled and could hold fluid e.g. biscuit or cake tray.

  • Is it made from expanded polystyrene e.g. foam meat or food tray, cup or packaging 'peanuts'?

    It must be put in the red-lid waste to landfill bin.

  • Is it a plastic lid?
    Large lids e.g. ice cream and butter/margarine container lids can be placed in the yellow-lid recycling bin.

    Loose small, rigid plastic items e.g. milk and drink bottle lids, bread tags and straws either fall off the conveyor belts at the Material Recovery Facility (MRF) and are treated as waste, or are caught between the paper and cardboard, contaminating that recycling stream. Consequently, loose, small rigid plastic items should be placed in the red-lid waste to landfill bin.

    However, they can be recycled if placed inside a milk bottle. When the bottle is full, the lid should be put on and the bottle placed in the recycling bin. Sorters at the MRF will easily be able to identify the milk bottle with lids for recycling with other mixed plastics. 

  • Is it a soft plastic e.g. plastic bag, film wrap, magazine and newspaper wrap, food packaging?
    Soft plastics must be put in the red-lid waste to landfill bin. Some clean, dry, soft plastics can be recycled at some Coles and Woolworths supermarkets.

See recycling bin for more information about what can and cannot go in your recycling bin.

Australasian Recycling Label

You may have noticed a different labelling system on some products. This is the Australasian Recycling Label which is a standardised labelling system for Australia and New Zealand. It aims to provide recycling information to consumers so that they know which parts of their packaging belong in the recycling bin, the rubbish bin, or can be returned to Coles or Woolworths stores at their soft plastic collection bins.

There are three types of recycling information that can appear on a label:
