During the development of plastic and plastic products in the past century, it has brought great contributions and infinite convenience to human production and life. At the same time, a large amount of waste plastics also put a lot of pressure on the environment. Rarely recycling. According to foreign media reports, the recycling of waste products does not always give new life given to plastic products. On the contrary, humans are gradually being drowned by plastic... The final result of plastic recycling treatment is not as simple as many people imagined. John HOCEVAR, a US green and peaceful organization marine biologist, said that recycling is unlikely to give plastic products a new life. In fact, in the end, in the end, in the end, only 8.4%of plastic waste was recycled. There are many plastics, each with different characteristics and recycling value. Only a few types of plastics are recycled and reuse. The value of other products is small, and recycling that they are economical. This may be related to the type of plastic, the size and shape of the product itself, and the situation of the global recycling market. Plastics with low recycling value or no recycling value are more likely to be buried, entered the environment or burned. Especially some food packaging, It is made of multi -layer plastic. This means that plastic and other materials (such as foil or cardboard) are bonded together. For example, many well -known hot drinks (such as Starbucks Coffee Cup) cannot be recycled or degraded because the paper is covered with a thin layer of plastic. Once plastic and another material are bonded to form a multi -layer plastic, it is almost impossible to recycle. It should be noted that not all plastic products are the same. The number on a triangular recycling symbol in the bottom of the plastic indicates the degree of recycling of the plastic. In the garbage recycling treatment plant, plastic waste is classified based on these numbers (7 digital grades in total) marked. The more complicated the recycling processing of plastic products with higher digital grades, related statistics, and plastic waste with higher digital registration occupies us. 69%of the daily use of plastics, processing them is higher and consumes more energy than the cost of processing No. 1 and No. 2 plastic products. In the past few years, many garbage recycling institutions in the United States have sold plastic mixed garbage to Asian countries, but two years ago, these countries in Asia have banned the import of foreign plastic waste. Is plastic recycling meaningful? For No. 1 or No. 2 plastic bottle, the answer is yes, but it is a very sad result for difficulty recycling plastic materials.
