Composting

Why compost?

Food scraps are organic, so what’s the problem sending it to landfill?

In a landfill, food waste decomposes and produces high amounts of methane, a potent greenhouse gas. In contrast, composting food scraps produces carbon dioxide, which is much less potent than methane. The remaining carbon is returned to the soil as fertiliser.

Nearly half of the average waste in a household bin is organic waste. Most of this can break down naturally in a household compost bin.

Start composting your food and garden waste to:

  • reduce the amount of waste you send to landfill
  • improve your soil structure and nutrient levels
  • trap moisture in your soil so it saves water (when used as mulch).

Home composting options

Whether buying a composting bin or building your own, home composting is easier than you might think. Many types of composting bins are available including:

  • outdoor bins, with or without ventilation and ground holes
  • tumblers
  • open enclosures
  • indoor/benchtop composters
  • in-ground composting
  • vermicomposting (worm farms).

You can also check local council websites to see if there are home composting programs or options for composting at community gardens.
