It was reported on August 22 that according to the foreign media techxplore, CSIRO, Australia's national science institution, and the University of science and technology of Sydney cooperated to develop a prototype of smart bin. The intelligent trash can uses technologies such as Internet of things, sensors, artificial intelligence, infrared spectroscopy and machine learning to automatically classify different garbage such as metal, plastic and glass. The smart trash can also convert waste into usable resources. The purpose of the intelligent trash can is to improve the garbage recovery rate and reduce waste pollution. Wei Ni, chief research scientist of CSIRO, said: "the smart trash can is very practical. It can effectively improve the garbage recovery rate and its use method is very simple. It can be arranged in shopping centers, schools, cinemas, cafes, airports and other places." ▲ Larry, CEO of smart bin CSIRO? Dr. Marshall said that taking new South Wales, Australia's most populous state, as an example, it produces 800000 tons of plastic waste every year, of which only 10% is recycled and the rest goes to landfills. In order to solve the problem of plastic waste, CSIRO launched the "end plastic waste task", which aims to reduce the plastic waste in the Australian environment by 80% by 2030. Reduce the amount of plastic waste entering the Australian environment by 80%. Dr. Marshall also said: "science can create higher income jobs through waste utilization, promote the development of new technologies in Australia, and then transform our economy into a circular economy. Science can not only drive the economy, but also protect our environment." CSIRO's 2021 circular economy roadmap points out that circular economy innovation can realize resource recovery by designing new products, new materials and adopting new business models, thus creating three times of employment opportunities for circular economy. If Australia's economic recovery rate is increased by 5%, the circular economy will increase GDP by US $1 billion. Conclusion: Australia is committed to developing circular economy. Smart trash can is one of the new products displayed by CSIRO during the "National Science Week" in Australia. The waste recycling technology used in this product can contribute to the development of circular economy in Australia. According to the data report released by the Australian government, in 2020, the amount of garbage produced in Australia was about 74.1 million tons, with a per capita of 2.94 tons. In order to solve the waste produced, the Australian government is committed to improving the waste recovery rate and developing a recycling economy. Relevant data show that in 2020, the recycling rate of Australian tons of garbage reached 60%. Australia used to rely on garbage export to transfer garbage, but in recent years, with the improvement of environmental awareness, all countries no longer import Australian garbage. Therefore, Australia began to look for ways to recycle and treat garbage in its own country, and devoted itself to developing garbage recycling technology to promote the development of circular economy. Now it seems that Australia
