Where do the discarded plastic bottles go?

Plastic bottles are widely used polyester (PET), polyethylene (PE), polypropylene (PP) as raw materials, after adding the corresponding organic solvent, after high temperature heating, through plastic mold through blow molding, extrusion blowing, or injection molding plastic containers. Mainly used for liquid or solid disposable plastic packaging containers for beverages, food, pickles, honey, dried fruits, edible oil, agricultural and veterinary drugs, etc.

When plastic bottles store fat-soluble organic substances such as wine and vinegar for a long time, chemical reactions will occur. Long-term consumption of ethylene-contaminated food can cause dizziness, headache, nausea, loss of appetite, and memory loss.

With the rise in global crude oil prices, the price of plastic products, one of petroleum derivatives, has naturally risen. There are many types of plastic products, most of which are high polymers, some of which can be recycled and recycled. Some have no recycling value, and the basic destination is incineration and landfill.

The physical recycling method of PET plastic bottles is relatively simple, mainly drying and granulating the cleaned PET plastic bottle waste. One is to cut waste PET plastic bottles into pieces, separate HDPE, aluminum, paper and adhesive from PET, and then wash, dry and granulate the PET fragments; Impurities such as bottle caps, bases and labels are mechanically separated, then washed, crushed and granulated. Recycled PET must not contain PVC impurities, otherwise it will affect the color of PET. The stone paper bottle is relatively simple. The discarded bottle can be naturally degraded under the sunlight for 6 months. Its own material is calcium carbonate, which is not harmful to the environment. The stone paper bottle can be widely used in cosmetics and medical markets.
