Smart trash can has warm tips for more environmentally friendly garbage classification

　　There's a trash can that praises you when you throw in the "right" trash, and criticizes you when you don't. There is such a garbage treatment scheme, the future of the garbage does not throw into the trash can, but directly by the garbage truck recycling...... A few days ago, at the end of the second "zhixing cup" college students social practice contest commendation conference, the reporter found that a number of winning projects and green environmental protection, low-carbon energy saving.

　　Liu jing, who once worked as a "cabbage" in the expo garden, and her classmates found that many visitors lacked the awareness and basic knowledge of garbage classification through "looking, smelling and asking questions" about the waste disposal system of the expo garden during their volunteer service. In response, they designed a "smart classification of audible trash bin." This kind of trash can adopts the infrared spectrum analysis method, installs the induction device in the different garbage delivery port, quickly detects the spectral value of different substances, such as metal, glass, organic matter, and so on, and carries on the intelligent classification to the trash.

　　Not only so, trash can still be humanized "praise", "criticism" to remind the choice of the correct release mouth. Once garbage is close to the wrong delivery port, it will immediately close this opening, and said: "very sorry, you chose the wrong garbage delivery port, please choose again, adhere to garbage classification, to create a low-carbon life, thank you for your cooperation! For the accurate classification, it says: "congratulations, you chose the right garbage outlet, thank you for your contribution to environmental protection, please continue to adhere to the garbage classification.

　　Faced with the same problem, wang mingyuan, a junior at tongji university, and his team cloned the program into an ancient city in xinmi, henan province. Garbage is not landed is not thrown into the trash can, but directly by the garbage truck recycling.

　　In the ancient city, wang mingyuan and his colleagues, in consultation with the local government, designated a rectangular and densely populated residential area as the pilot area of the "garbage does not fall" program. In this area, through 7 days of field investigation and research, they planned a garbage truck driving route, and collected garbage at fixed points on a regular basis. And with a number of small lane in the tricycle route, door-to-door collection of garbage. The garbage truck is divided into early and late buses and stops at 10 stations. Each station has a stop sign and stops for 3 to 10 minutes each time. In this way, there is no need to set up garbage bins in the residential areas, and the garbage is sorted out when the sanitation personnel collect it.
