Types of plastic
To facilitate further processing, some plastic products, you can find a special symbol (a triangle of three arrows in the center of it - the figure). It is a sign of recycling, which divides all the plastic into seven groups. In the home icon provides information on how you can later use plastic ware. In special cases, it is generally better to refuse.
This type of plastic is the most common. In polyethylene terephtalate bottle bottled juices, water, sunflower oil, ketchup, mayonnaise, and even cosmetics. Cheap, durable, safe. Due to the low barrier properties in the bottle can penetrate ultraviolet and oxygen, and vice versa, carbon dioxide contained in the mineral water can penetrate through the wall to the outside. There is no danger to health. Doctors do not recommend use of such bottles, as they can not be washed clean enough.
Recycling: Mechanical and physical and chemical. From the products of such bottles can be made from scratch.
Made bottles for shampoos, cosmetics and detergents, motor oil cans, disposable utensils, containers and containers for food products, containers for freezing food, toys, various caps and lids for bottles and vials, durable shopping bags, packaging bags and boxes.

Resistant to acids, alkalis, solvents, oil, gasoline, kerosene, a good insulator, does not burn.
The difficulty in recycling, toxicity. It is the most toxic and dangerous to the health form plastics. The combustion of PVC are produced highly toxic organochlorines. After 10 years of service, products made of PVC, are beginning to devote themselves to the environment toxic organochlorines. The most annoying thing is that to give more flexibility, polyvinyl chloride continue to use in the manufacture of children's toys. Once in the blood, PVC can cause hormonal disorders in humans.
