Some food waste is unavoidable, such as banana skins and apple cores, but sometimes edible food, such as sandwiches and whole fruit, are also thrown out.
Wasting food has a significant impact on our resources. When we waste food, we waste the resources used to grow it, such as water, soil, and energy. All the energy used to process, package and transport food to our homes is also wasted. The estimated annual cost of food waste to the Australian economy is $20 billion (National Food Waste Strategy 2017).
