Home composting and worm farms - the benefits

Home composting and worm farming are some of the most natural and efficient ways of recycling. It is easy to do, cheap and provides many benefits:

  • Improves garden health and soil structure by adding nutrients.
  • Reduces water use in the garden.
  • Saves money spent on fertilisers and mulch.
  • Reduces the cost of waste disposal to the community.
  • Reduces greenhouse gases produced by rotting material in landfill.
  • Saves landfill space.

It's simple! All you need to do is put your kitchen scraps and other organic material into a compost bin or worm farm rather than your rubbish bin.


Compost bins

What materials can go in a compost bin?

Any item that was once part of a living thing can be composted, listed below are some of the more common items that are suitable for home composting:

  • Bark
  • Bread
  • Cereals
  • Dairy products*
  • Eggshells
  • Flowers
  • Food scraps
  • Fruit and vegetables
  • Garden waste
  • Grass clippings
  • Hair
  • Hay/Straw
  • Horse and chicken manure
  • Leaves
  • Meat*
  • Paper
  • Sawdust
  • Small twigs
  • Vacuum cleaner dust
  • Wood ash
  • Woodchips
  • Wool

* Avoid placing meat or dairy products in the compost until you are confident and experienced with composting methods and your compost heap is working well.

Compost Bin Tips for successful composting

  • To get your compost heap working well you need a mixture of ingredients as well as water and air.
  • If you add dry materials to your heap make sure you add a sprinkle of water; your compost heap should be as moist as a well wrung out sponge. 
  • Turn your compost heap, with a garden fork, every couple of weeks to make sure it is getting enough air. 


Worm farms

What materials can go in a worm farm?

As a guide worms will eat any item that was once living thing, listed below are some of the more common items that are suitable for worm farms:

Worm Farm

  • Coffee grounds
  • Egg cartons (torn & soaked first)
  • Eggshells
  • Fruit and vegetables
  • Hair clippings (including animal)
  • Manures - well aged horse and chicken manure
  • Newspapers (torn & soaked first)
  • Paper
  • Pizza boxes (torn & soaked first)
  • Tea bags and leaves
  • Vacuum cleaner dust

To increase the rate that worms eat your waste, we suggest mashing, blending or chopping the food into smaller pieces. Tips for successful worm farming:

  • A handful of lime or crushed oyster shells or eggshells or ashes from a fire will help to balance the acidity.
  • Pre-soak any dry materials such as paper, card and old manures to keep the moisture levels up in your worm farm.


Why should I compost or use a worm farm?

Nearly half of the rubbish thrown in the red rubbish bin could be made into compost.

In the City of Marion alone, this equates to an average of 3kg per household per week or almost 5,500 tonnes across the entire council area per year of this material going straight to landfill.

Kitchen Caddies for food scraps
Download the latest 
Bin Collection Calendar

City of Marion residents can use a kitchen caddy to collect all food scraps in the kitchen for disposal into the green organics bin so it can be composted rather than wasted.


How do I get a Kitchen Caddy?

Kitchen Caddy Food Scraps

Residents with proof of identification and residence showing that they live in the Marion Council area, can collect a FREE kitchen caddy with a roll of compostable bags from the City of Marion Customer Service Centre at 245 Sturt Road, Sturt. 

You can fill out a Kitchen caddy collection form(280 kb) and bring it when collecting your kitchen caddy.

Where can I get more bags?

Residents can buy replacement caddy liners from the Administration Centre on 245 Sturt Road or from any of the Marion Library branches at the small cost of $6 per pack of 75 bags (which will last for around 6 months).

Remember, you don't need to use the corn starch bags, you can simply place your scraps loose in the green bin or wrap them in newspaper.

It is important to only use compostable bags in the caddy, never biodegradable or other plastic bags as these contaminate the organics and cause big problems for composting. The green bags that come with the caddy are made from corn starch, which is 100% compostable.

What can I put in the Kitchen Caddy?

All food scraps such as:

  • All dairy including cheese and yoghurt
  • Cake, bread and biscuits
  • Meat, bones and seafood - raw and cooked
