Compost & Worm Farms

Food is the most wasted commodity in Australian households.  1 in 5 grocery bags of food ends up in the bin. That is equivalent to $5.3 billion a year. 

Composting, worm farming or using a bokashi bin are ideal ways to turn unavoidable food scraps, into nutrient-rich fertiliser for your garden. You can buy subsidised composting systems through Council or via the Compost Revolution (which incorporates on-line tutorials and trouble-shooting guides).Compost Revolution


Composting is the natural decomposition of organic materials such as insects, bacteria and fungi into a dark, soil-like substance called compost. Almost half of the waste we produce is compost-friendly, so it’s a fantastic way to reduce landfill. You can use compost as a fertiliser or a substitute for potting mix.

Worm Farming

Worm farms are a great way to turn leftover kitchen scraps into fertiliser without taking up much space. Even if you have a balcony instead of a backyard, all you need is a cool spot with lots of shade. Just buy or make a worm farm, get some worms, and start feeding them. They will produce soil-like ‘castings’ and a liquid which both make great natural fertiliser.

Bokashi Bucket

The Bokashi Bucket is a simple and convenient composting system designed to be stored in your kitchen.  The use of microorganisms in the Bokashi Mix permits rapid fermentation, eliminating the odours associated with putrefaction and decay. You can compost fresh fruit and vegetables, prepared foods, cooked and uncooked meats and fish, dairy, eggs, bread, coffee grinds, tea bags, wilted flowers and tissues.

Full instructions are provided with each bucket purchase.

Food Waste Disposers

Food waste disposers (also known as insinkerators) are systems that grind food scraps into smaller chunks, which are then discharged into the sewerage system. 

Sydney Water does not encourage the installation of food waste disposers because of:

  • The additional water used per household to discharge the food waste into the drainage system (approximately 4 litres per household per day)
  • The increased load food solids places on sewerage transport and treatment systems
  • The additional impact on receiving waters

Note: Food waste disposers are not permitted to be installed in commercial properties
