Composting and worm farming are natural recycling systems whereby organic waste, such as food scraps and garden prunings, is broken down into smaller nutrients. The organic resources released in the waste can also improve soil health and avoid the use of chemical fertilisers in your garden.
Both composting and worm farming are easy and important ways to give nutrients back to your soil and reduce the amount of waste going to landfill.
Choose a system that works for you
It's important to choose a system that works for your household.
Compost bins are often a better option if you live in a house with a garden as they can take most food scraps, garden prunings and leaf-litter.
Worm farms are limited to some fruit and vegetables, although they are very compact and don't smell – making them ideal if you live in an apartment with a balcony or small courtyard.
If you're not sure which system is for you, check the table below:
| You want to: | Compost | Worm Farm |
|---|---|---|
| Compost garden clippings | 
| 
|
| Keep your bin inside, in a balcony or small courtyard |
|
|
| Compost large amounts of food waste (more than two people per household) |
|
|
| Keep your bin outdoors on bare soil |
|
|
| Maintain your bin in full sun; ensure it is able to tolerate heat |
|
|
| Compost a variety of foods including citric fruits, onion and garlic |
|
|
| Produce liquid fertiliser |
|

Each household is entitled to claim the rebate once only and the offer is only available to the residents living in the City of Parramatta Local Government Area.
Compost together with neighbours and community
If you have space or other limitations that prevent you from having a compost bin or worm farm yourself, you can still compost your food waste in other ways.
Work out an arrangement with your neighbours who has compost bin or worm farm and donate your food waste to their bin. Alternatively you can find a friendly composter on ShareWaste who will accept your food waste.
If you have shared green space in your apartment block, you can talk to your agent, landlord or strata about starting up a communal compost bin or worm farm. There are many apartment dwellers who have done this as a way to reduce their food waste. Council can also provide free training for your block to help with the process.
