Nowadays, the rise of take-away industry has led to the development of disposable tableware. All these take-away tableware are one-time use and the annual amount of usage can up to 10 billion or more. However, many people do not have the habit to categorize these plastic tableware after using it, and some people even just flinging it. Therefore, when we enjoy the convenience of disposable tableware has brought to us, the environmental pollution problems also follow up.
Disposable lunch boxes can not be naturally degraded, and were scattered anywhere which not only caused visual pollution, but also caused a potential hazard. The waste plastic products scattered in the big cities, tourist areas, railways have caused a huge damage to the landscape and the environment, affected the overall beauty of scenic spots. When the waste lunch boxes were threw into the natural environment, it is difficult to degrade by themselves, which may cause a long-term deep-seated environmental problems and potential pollution. The structure of polystyrene tableware is stable, and can not be destroyed easily by natural microbes, so it will exist in the natural environment for a long time without decomposition. At present, the common way to deal with garbage is to landfill, and the existence of plastic tableware will affect the disposal capacity of landfill waste.
Therefore, to solve these environmental problems is very important and urgent. However, how to deal with this kind of white pollution? Recycling is a good way to relieve the pollution. By the way, these disposable tableware can not be used for utensils, and there are many difficulties in recycling, such as the economic benefits of recycling, recycling technical problems, so the recovery rate is very low, especially the expanded polystyrene tableware. Therefore, how to efficiently take polystyrene recycling and reuse disposable foam lunch boxes is a complicated problem.
