Food waste is a major problem around the world, especially in our rapidly growing country. The amount of food waste we generate is impacting the environment in many different ways.

When food and other organic material break down in landfill they create methane (CH4). Methane is a greenhouse gas that traps heat in the air.

Food waste that breaks down in landfill can also release nutrients into the environment. Extra nutrients can disrupt the natural balance of an ecosystem.

To protect our environment and current lifestyles we all need to: Think Food – Rethink Waste. The tips below could help you to reduce your food waste.

Food supply chain

Australia's food supply chain has a significant impact on our contribution to the greenhouse effect.

When you throw out food, what you put in the bin is not the only resource being wasted. You are also throwing away all the resources used to produce that food and get it from the farm to your plate – such as water and energy.

Roughly 23 percent of Australia's total greenhouse gas emissions are from the food supply chain.

Reduce food waste at home

You can reduce the amount of food being thrown out at home by following some simple steps.

• Reuse your organic waste, such as food scraps and grass clippings, by making a worm farm or compost system.
• Plan your meals for the week before you go shopping.
• Write a shopping list after you have checked what you already have at home.
• Always store and prepare food by following the instructions on the packaging.
• Do not store opened foods in cans. Tin and iron can dissolve, which will spoil the food.
