Why Reduce Waste?

The average Australian generates 540kg of household waste per year. Much of this ends up in landfill where organic matter produces methane (a powerful greenhouse gas) and plastic persists for hundreds of years. Reducing waste at source is more impactful than recycling — the waste hierarchy is Refuse, Reduce, Reuse, Recycle, in that order.

The Highest-Impact Changes

  1. 1

    Compost food scraps

    Food waste accounts for approximately 30% of household rubbish. Composting or worm farming diverts it from landfill and creates nutrient-rich fertiliser for the garden. A simple compost bin ($30–50 at Bunnings) handles most fruit, vegetable and garden waste. No garden? Many councils run food waste pickup or have community compost sites. Bokashi bins work indoors for small spaces.

  2. 2

    Switch to reusable bags, cups and bottles

    A reusable shopping bag replaces hundreds of single-use plastic bags over its lifetime. A reusable coffee cup (KeepCup etc) replaces 1–3 disposable cups per day for daily coffee drinkers — 365–1,000+ cups per year. A reusable water bottle eliminates plastic bottle purchases. These swaps are simple once habitual.

  3. 3

    Plan meals and buy only what you need

    Food waste is the biggest component of Australian household rubbish. Planning meals for the week before shopping dramatically reduces the amount of food that goes bad before being eaten. A weekly meal plan + shopping list takes 10 minutes and saves both money and waste.

  4. 4

    Choose products with less packaging

    When shopping, actively choose products with minimal packaging — loose produce over pre-packaged, concentrated cleaning products (less water and less packaging), solid shampoo bars and soap bars instead of plastic bottles. This drives demand for less-packaged options over time.

  5. 5

    Buy second-hand and repair rather than replace

    The manufacturing phase of products creates far more waste and emissions than the disposal phase. Buying second-hand (clothing, electronics, furniture, books) and repairing items that break reduces the demand for new manufacturing. A $10 repair extends a product’s life; a new purchase creates new waste.

Recycle correctlyIncorrect recycling (wishful recycling — putting non-recyclables in the bin hoping they will be recycled) contaminates entire loads of recyclables. In Australia, the yellow bin accepts: cardboard and paper (dry), glass bottles and jars, rigid plastic bottles and containers (look for the recycling symbol), aluminium and steel cans. Not in the yellow bin: soft plastics, takeaway cups, food-contaminated containers, broken glass. REDcycle (in some states) and Coles/Woolworths collect soft plastics.

Frequently Asked Questions

Yes, but it is less effective than reducing and reusing. Recycling requires energy and has its limits (plastics can only be recycled a limited number of times). The most impactful actions in order: refuse unnecessary items, reduce consumption, reuse and repair, then recycle properly. Recycling is the last resort in the hierarchy, not the primary solution — but doing it correctly is still significantly better than landfill.
Soft plastics (bread bags, pasta bags, cling wrap, plastic shopping bags) cannot go in the kerbside recycling bin. In Australia, the REDcycle program collects them at Coles and Woolworths — check the status of this program as it has had disruptions. Some councils have soft plastic drop-off points. Reducing soft plastic use at the source (buying fresh bread, loose produce) is more effective than relying on specialist recycling.
