The design of vocational school students has established a new mark that can be used by excellent waste business operators.

Yokohama City certifies waste collection and transportation companies that serve as examples as "general waste collection and transportation business excellence companies." As excellent company of 2023 was decided, we give certificate. In addition, as a symbol of an excellent company, we will newly establish a mark created by a vocational school student studying design in Yokohama City and present a letter of appreciation to the vocational school student who designed it. Certified businesses can use the mark on the body, business cards, and their homepages of garbage trucks.
