In recent years, "degradable" has become a popular word, and "degradable garbage bags" are also hot in the market. Some experts believe that degradable garbage bags can solve the difficulties and cost problems in the process of garbage classification, and are one of the development directions of garbage classification in the future.
"Convenience" and "environmental protection" have become keywords
In the sales of "degradable garbage bags", "convenience" and "environmental protection" have become keywords, which are also the main factors for many customers when purchasing.
There are multiple versions of degradable garbage bags
It is understood that there are three main types of degradable garbage bags commonly seen on the market: the first is PE material, which can be directly thrown into the trash can; the second is PVC material, which needs to be thrown into the trash can together with the plastic garbage bag; the third is PET material, which can be directly thrown into the trash can.
Currently, the degradable garbage bags sold on the market are mainly divided into two categories: one is the common white plastic bags in supermarkets, which are relatively low in price; the other is degradable plastic bags, which are relatively high in price. Citizens can choose according to their needs.
Many experts said
Sun Youhai, a researcher at the Ecological Environment Research Center of the Chinese Academy of Environmental Sciences, believes that "degradable garbage bags" are just an improvement on garbage bags, and they are not brand new products themselves. In the future, "degradable garbage bags" may add some polymer materials during the production process to improve the strength and toughness of the bags. In addition, some researchers have conducted degradation experiments on degradable garbage bags, and the results show that "degradable garbage bags" can be completely decomposed into water and carbon dioxide under natural environmental conditions. But this is only a laboratory research result, and it may take a long time in actual application. In addition, some experts also said that the "degradable garbage bags" currently sold on the market are mainly made of biodegradable plastics, but these plastics are often non-biodegradable, so there will not be much impact in actual use.
