Plastic waste, how to deal with

Plastic waste, how to deal with plastic waste, how to deal with? As we all know, a large number of used in food packaging there are three kinds of plastic products: PVC, polyethylene, polystyrene. In a short period of time, used for holding the cooking oil is no obstruction to human body health. But, use them to dress up cooking oil for a long time, can contaminate food, cause harm to human body. This is because, this kind of packing bottle has the characteristic such as high transparency, easy to aging, in the air will be affected by the role of oxygen, ozone, ultraviolet a strong odor, polymerization content itself with aging, if cooking oil that is used for long-term storage, easy to make these food metamorphism. In addition, the elements in the PVC vinyl chloride not only toxic, and extremely easy to decompose in the acid and grease and exhalation very poisonous chlorine, hydrogen chloride and added in the PVC plasticizer, such as the phthalate esters, has toxicity, and used as a stabilizer of organic tin, lead, cadmium and chemicals are toxic, toxicity is larger, and easy to dissolve in oils and fats. Although plastic polystyrene belongs to low toxic substances, however, its composition and styrene volatilization components ethyl benzene, isopropyl benzene are toxic, and is easy to dissolve in oils and fats. Polyethylene plastic itself has no toxicity. But after contact with grease, it can break down of low molecular compounds, these low molecular will produce toxic elements dissolve in grease.
