Facts and Figures
- Commercial refrigeration systems consume around 6,600 Gwh per year in Australia. This is enough to power around 1.3 million homes.
- Inside restaurants refrigeration accounts for 10 to 16 percent of energy consumption, and inside supermarkets refrigeration accounts for 44 to 62 percent.
- A coolroom compressor can be responsible for up to 60 percent of a system’s total energy use.
- Greenhouse gas emissions from commercial refrigeration systems are around 6.6 million tones of carbon dioxide per year. This is equal to the annual greenhouse emissions from approximately 1.3 million cars.
- Globally decomposing food waste creates 3.3 billion tonnes of greenhouse gases from rotting landfill, making food wastage the third top emitter of greenhouse gas emissions after the USA and China.
- It is estimated that the total gross value of the Australian agricultural food chain is around $172 billion per year.
- Up to 40% of food and beverages produced in Australia are either lost during the production and manufacturing process, or wasted by Australian families.
- In Australia 3.1 million tonnes of edible food is discarded from commercial and industrial sources, costing around $10.5 billion in waste disposal charges and lost product per annum.
A substantial amount of resources and energy is used each year to keep food cold or frozen in commercial establishments, including restaurants, grocery stores, convenience stores and fast-food restaurants.
The foodservice industry has the highest rate of food waste and energy consumption per square metre, due to the need for storing produce in specialised, high-energy-consuming equipment for various ongoing periods of time.
