How to compost against climate change

6 November 2019

Take a powerful action against climate change by reducing your food waste, and get a discounted home composting system thanks to our partnership with Compost Revolution.

When you throw organic matter in your normal bin, it ends up in landfill. Without exposure to air or the microorganisms needed for it to decompose naturally, it rots. This creates methane – a potent greenhouse gas.

If food waste were a country, United Nations research tells us it would be the world’s third highest greenhouse gas emitter, after China and the United States.

Aside from its significant environmental impacts, food waste also costs the average Victorian household $2200 each year – we throw out one in five bags of food we buy.

Across Australia, five million tonnes of food ends up as landfill each year. That’s enough to fill 9000 Olympic-sized swimming pools, and it costs the Australian economy $20 billion.

Imagine the positive impact we could make if we turned this around.

We can all do our part to reduce organic waste, even if we live in an apartment. Worm farms, for example, take up very little space, have very little odour, are simple to use, and produce rich fertiliser for your plants.

You can feed your worms fruit and vegetable scraps, egg shells, tea leaves, tea bags, coffee grounds and much more. But avoid citrus and acidic foods such as lemons, oranges, onions and garlic, meat and dairy products.

Worms aren’t the only way to make a difference. Here are our eight top tips to avoid food waste.
