Household Organic Recycling

In April 2023, the City is commencing a new program to support household organic recycling. Reducing organic waste at home is so important, and we want to encourage our residents to learn more about how to do this.

As part of this initiative we will be:

  • Hosting quarterly educational workshops about reducing organic/food waste, worm farming, composting and more
  • Introducing a rebate scheme for the purchase of worm farms and compost bins

What is Composting?

Composting is a natural recycling method. It is one of the most effective actions we can take to reduce waste, combat climate change, and cultivate healthy soil. By composting our food scraps and yard waste, we can convert our waste streams into a beneficial, value-added soil amendment that we can use to protect the environment and build resilient communities.

Subsidies are available for worm farms, compost bins, and bokashi bins. Different home waste compost systems are appropriate for different households and their waste needs. Learn more about the best composting unit for you, what you can compost, upcoming Reducing Food Waste workshops, and the City's rebate for eligible residents.

Why should I compost?

Every year, food and garden waste account for nearly half of our household garbage. Composting can recycle the majority of this organic waste.
By composting food scraps and organic garden waste, you can:

  • Reduce the amount of organic waste that goes to landfill, thereby reducing greenhouse gas emissions and leachate, which can pollute land, groundwater, and waterways.
  • Enhance soil quality and garden vitality by releasing nutrient-rich soil.
  • Control plant diseases and pests, reducing or eliminating the need for chemical fertilisers and manures and allowing you to save money.
  • Helps soils retain moisture, requiring less watering.

Dwelling suitability

House in any location with a garden

There is no need for a garden in houses or apartment buildings.

There is no need for a garden in houses or apartment buildings.


A sunny location outside, preferably away from the house, will suffice.

Can be either indoors or outdoors. 

Can be indoors or outdoors, but the best location is outside in the shade. 


Variable. Aeration and the carbon/nitrate ratio are important factors. If properly maintained, the process is quick.

Break down into a liquid quickly, though dry scraps take longer and must be buried.

Worm-dependent, but generally fast-moving processes

Odour level 

Dependent on carbon/nitrate ratios. If properly maintained, none.

There will be no odour if the bin is kept sealed in an airtight container.

If the worm farm is well maintained and scraps are digested, there will be no odour.

Maintenance costs 

Once set up, there is no additional cost.

Approximately $20 per bokashi mix.

Did you know?

Food waste in Australia is an increasing problem, and it is growing at an alarming rate. The Australian government estimates we waste about $20 billion in food annually. 

Food waste is responsible for around 8% of global greenhouse gases, because spoiled and rotten food sitting in landfill produces methane, a harmful gas which is 28 times more potent than carbon monoxide.

About the Free Educational Program 

How To Reduce Your Food Waste workshops are held quarterly. These workshops are free for anyone to attend and will cover topics relevant to waste reduction, compost, worm farms, bokashi bins and more.

Frequently Asked Questions (FAQs)

What is a composting unit?

A composting unit is a container into which organic waste is placed to be composted over time. Compost bins, bokashi bins, and worm farms are examples of these.

Most composting units are designed to accelerate organic matter decomposition through proper aeration and moisture retention. The right combination of air and moisture creates ideal conditions for the activity of aerobic organisms that convert organic materials into compost.
