German PET waste bottle recycling has become a "Chinese sweater" is also worth pondering, the German market flows more than 8 million PET bottles every year. Garbage recycling companies take the bottles, clump them or crush them into pieces, and sell them to China at a relatively high price. According to the calculations of relevant people, a bottle that can hold 16 liters of drinks can be made into a sweater. Back in 1993, all plastic bottles went to the trash and a small part was recycled. Since the implementation of the charge 4 years ago, supermarkets must recycle empty bottles, PET bottles have embarked on a journey of thousands of miles: go to China, turn into synthetic woolen sweaters, and then return to Germany. China's textile industry has a huge demand for plastics. Although businessmen add another yard to the price of German recycling companies, imports are cheaper than producing the raw materials themselves. Freight rates from Hamburg to Hong Kong are low because there are many empty spaces on board after the freighter ships bring in and unload the textiles from China. The cost of producing in China is low because the labor force is cheap and environmental and social standards are not perfect. In Chinese factories, these PET ingredients are sorted by color, cut into pieces and melted. After processing, PET bottles are returned to Germany in the form of textiles and sold in Germany. The value creation embodied here is enormous: a synthetic tweed sweater costs between 50 and 100 euros, while the material used is only 32 euro cents. There is no end in sight to the hunger of old plastics in the Far East. China is no longer able to meet its needs with first-hand raw materials. In this context, second-hand raw materials like PET are doubling in value. The fact that empty plastic bottles are shipped to China and used as raw materials suggests that there is in fact a world market for second-hand raw materials. 10 years ago, garbage was dumped in the dump, "then we were a consumer and dump society." "The example of the German resale of processing in China illustrates the problem," and the market development shows all consumers that some waste has indeed been recycled. "

In addition, for example, in the past two years, Intercontinental Recycling Corporation of India has produced qualified recycled PETs, and it is reported that India's state-owned intercontinental recycling company Indian-owned Intercontinental Recycling's plant in the Skelmersdale region of northern England began trial operation in November 2007, and according to the plan, the plant can recover and convert 30,000 tons of waste plastic bottles per year. In addition, the unit has some sorting, rinsing and drying equipment, and the product will produce hot can bottle flakes for non-edible products. Consumers can use this material to package non-edible products or as an intermediary to separate two layers of edible substances. Currently in the UK, the market price of recycled PET flakes for non-edible products is around £600/tonne.

In addition, Japanese companies have successfully researched and developed recycled PET modifiers, recalling that Japan fully implemented the container recycling method in April 2000, and the recycling of PET bottles reached 390,000 tons in 2006, which only reached 60% of the recovery rate. For the technical problems of PET recycling and reuse. The two grades of recycled PET modifier "AR-P-1000" and "AR-P-1100" were successfully developed by the Japanese company "AR-P-1100" to the market. The main features of AR-P recycling modifiers are: (1) no drying treatment is required when used. (2) Very stable at room temperature. (3) Suitable for all plastic molding processing equipment. (4) Can be arbitrarily colored. (5) Can be directly added to the mix. (6) Improve the impact strength of PET recycled recycled molding materials. Since AR-P is dispersed in a fine state in the recovered PET molding material, the mutual interfacial tension is small under the action of the shear force of the molding process. The viscosity ratio of AR-P and the recovered PET molding material is 1, and the dispersion is good, which improves the impact strength of the recovered PET molding material, for example, when adding 5% "AR-P", the notched impact strength is increased from 2KJ/mz to 5.5KJ/m2. Low temperature impact strength at a 10 ° C by 1. BkJ/mz increased to SkJlm2o(7) improves the viscosity of recycled PET molding materials, improves the flow performance of PET melt molding materials, and is suitable for molding and processing extruded molding products with complex shapes and special-shaped materials.
