The Sydney Olympic Games achieved great success in the recycling of waste, which also won the "Green Olympics" award. During the Olympic Games, there are about 660 tons of garbage generated each day, and 76% of them are recycled. Australia’s success in waste recycling is mainly due to the use of biodegradable plastics as a package for its fast food. Due to the use of biodegradable plastics, plastic waste is reduced, the amount of plastic in plastic waste is reduced, and the circulation of organic components is increased.
