        Now, let's learn about the environmental protection blue, harmful red, perishable green and residual black garbage bags designed by the manufacturers of classified garbage bags. In the future, with the participation of caring enterprises and public welfare organizations, we will distribute the garbage bags to community residents, and transfer the concept of "garbage classification starts from home, starts from you" to thousands of households. In the design process of environmental protection classified garbage bags, through the four different colors of blue, green, red and black gray, the different types of garbage can be effectively distinguished, and the color of the sorting garbage bin put into use in the city is unified. In this way, the citizens can form good classification habits as soon as possible when they participate in the household garbage classification.
