This initiative was carried out as part of an initiative by Professor Tatsuji Nashinaka of the Department of Embedded Software Engineering, Faculty of Information and Telecommunications, Tokai University, to realize a smart city.The smart trash can "Big Belly Solar" is an environmentally friendly trash can that does not emit CO2 and is equipped with a communication function that uses the energy of solar power generation. By utilizing IoT technology * and transmitting the garbage accumulation status in real time through the mobile phone network, it can be used to improve the efficiency of collection work and reduce costs, such as optimizing collection frequency, staffing, and trash can placement.

　Regarding the demonstration experiment, Professor Nadanaka recognizes that "Big Belly Solar is an IoT case that can embody how the overall operation related to garbage collection can be improved and what kind of effect it will bring by connecting the trash can to the network. In our laboratory, the theme of our research is from monitoring and control of "things" to independence through embedded software such as home appliances, and this demonstration experiment will be useful for society from a viewpoint other than improving the efficiency of garbage collection. I hope to verify how it will be useful and use it as a reference for future research themes. "

* IoT technology is a technology that connects "things" such as home appliances and health appliances other than IT to the Internet.
