Food waste is a significant issue in both households and industries, impacting the environment and resource management. A closed-loop system aims to tackle this problem by reusing every component within the system to achieve zero waste through reuse, recycling, or biodegrading.

What is a closed loop cycle?
a closed-loop system is a process where every component (e.g. food) is reused within that same system for as long as possible, with the objectives to reuse, recycle, or biodegrade all materials involved so as to produce zero waste (Laura, 2016)

Facts and Statistics
The food production/agricultural industry throws out 20-40% food before it reaches the consumer because the food might not look perfect. This is usually because of the consumer's exceptions of what food should look like ("Food Waste Fast Facts", 2019)
The average Australian household throws out $1,039 worth of waste a year which could pay for half a year's electricity bills ("Food Waste Fast Facts", 2019)
Australians throw away 20% of the food they purchase ("Food Waste Fast Facts", 2019)
the Australian Food and Grocery Council has a goal to reduce waste to landfill by 40 per cent by 2020 (Working together to reduce food waste in Australia, 2019)
8% of greenhouse gases are caused by food waste. Green house gases cause the planet to heat ("Food Waste Facts", 2019)
A head of lettuce takes 25 years to de-compost in landfill due to the lettuce not being exposed to oxygen and its inability to aerobic decomposition (Kye & Chai, 2017)
