The classification and placement of sanitation trash bins reflects the practical actions that human beings have taken to protect their homes, using color design, easy-to-understand graphic symbol design, container shape design, and special photosensitive and sensing technologies. Different colors of trash cans represent different meanings, which greatly improves people's awareness and behavior of classification in terms of visual effects. The colors of sanitation plastic trash cans are divided into three types:
Green: Recyclable garbage: plastic, paper, glass, rubber, aluminum products, etc.;
Red: Recyclable garbage: food, paper, cartons, etc.;
Black: non-recyclable waste.

Visually, sanitation trash cans are roughly divided into: sanitation classified metal peel boxes, sanitation square metal peel boxes, sanitation round metal peel boxes, indoor square metal trash bins, indoor round metal trash bins, and sanitation classified steel and wood trash bins , Sanitation square steel and wood trash can, sanitation round steel and wood trash can, sanitation mobile trash can, sanitation hanging trash can, sanitation round glass fiber reinforced plastic trash can, sanitation square glass fiber reinforced plastic trash can, sanitation classified glass fiber reinforced plastic trash can.

The logo selection of sorting trash cans use clear and typical physical graphics to convey information quickly and effectively. For example, a trash can in Shanghai that specializes in recycling old batteries is directly made into the shape of a battery. This kind of trash can design has gradually appeared in the city with the improvement of people's awareness of environmental protection.

"There are many sanitation trash cans on the street now, with the words 'recyclable, not recyclable' written, but the common garbage such as chewing gum, toilet paper, plastic cups and the like do not know which bucket to put in. Because I don't understand The classification standard of recyclable and non-recyclable garbage, so I hope to understand the difference between the two types of garbage, so as to facilitate the daily distinction. The selection of labels for classified waste uses clear and typical physical graphics to convey information quickly and effectively. For example, the three trash cans in the Ocean Park in Hong Kong, China, and a trash can in Shanghai that specializes in recycling old batteries are directly made into the appearance of batteries. With the improvement of people's awareness of environmental protection, such trash cans have gradually appeared in the city. In short, as long as we improve the existing trash cans, the problem of sorting garbage from the source may be solved by people. In this way, the urban domestic waste can be effectively managed and utilized, the infection of germs in the garbage can be eliminated, the workload of garbage transportation and disposal can be reduced, the processing procedures can be continued after simplification, and the urban garbage resources can be effectively utilized. Urban life is on the track of a virtuous circle.
