In our daily life, we can see the use of foam made of packaging boxes, tableware, bottles, and often difficult to recycle, these "white pollution" foam plastic is what garbage? In the garbage classification, how should we properly deal with these items?

us to understand what is foam. Foam is a kind of lightweight, durable and good thermal insulation material. Because of its good cushioning and sound insulation effect, it is widely used in packaging, transportation and protection of products. However, once the foam is discarded in the natural environment, it will have an irreversible impact on the ecological environment. Compared with other garbage, foam plastics take longer to decompose and release toxic chemicals, causing pollution and disaster to the air, water, land and other environments.

In order to avoid this "white pollution" damage to the ecological environment, we need to understand how to properly handle, recycle and use foam. We can choose alternatives, such as paper boxes, biodegradable tableware, reusable beverage cups, etc. When we cannot avoid the use of foam, we should try to reduce the amount of use, or put it into the designated trash can.

should also understand the classification of foam plastics when classifying garbage. Foam is divided into two types, one is marked "PS", that is, polystyrene foam (commonly known as white foam), which is classified as recyclable in the current classification standard; the other is marked "EPE" or no label, that is, polyethylene foam, which is generally classified as dry waste. Therefore, when putting in the garbage, the foam plastic should be classified according to its classification mark.

foam is a widely used item, we should understand its environmental impact, reduce its use as much as possible and recycle it correctly. Only when each of us is environmentally conscious can we work together to create a better and greener environment.
