PET plastic bottles are not only widely used for packaging carbonated beverages, drinking water, fruit juice, and tea drinks, but are also widely used in various fields such as food, chemical, and pharmaceutical packaging. PET plastic has a wide range of applications in the packaging field, whether it is packaging film, roll, or beer bottles, PET plastic is used. According to statistics, in recent years, the global PET production capacity has expanded at an average annual rate of about 9%, and China's PET production capacity exceeded 20 million tons in 2008, becoming the world's largest producer and consumer of PET. Due to the continuous increase in social demand, global PET polyester production has grown rapidly, and most PET products are disposable consumer goods, resulting in the generation of a large amount of PET waste. Waste PET materials have strong chemical inertness and are not easily degraded by air or microorganisms in a short period of time, which puts enormous pressure on the protection of the social ecological environment.
Therefore, the recycling of PET plastic bottles can not only solve environmental problems, but also serve as a new raw material resource to alleviate the contradiction of insufficient PET raw materials in China. Yes, looking back at China's 30 years of reform and opening up, although China has achieved remarkable achievements in the economic field, it has also brought serious damage to China's environment. Water pollution, air pollution, and so on. It has brought shrinkage to China's economy. People have gradually realized this issue and proposed a series of measures such as pursuing sustainable development, green GDP strategy, circular economy strategy, and so on. It can be seen that the recycling of PET plastic bottles is in line with the practical problems faced by China, and is of great benefit to environmental protection, resource conservation, and sustainable development.
Regenerated fibers are the main use of PET recycling. According to statistics, in 2007, the fiber use of recycled PET in China reached 89%, widely used in fields such as clothing, furniture, shopping bags, office supplies, daily necessities, and civil engineering materials. Guangdong Qiusheng Resources Co., Ltd. is one of the typical environmental protection enterprises that mainly produces recycled fibers. The company is committed to the research and development, production, and sales of recycled polyester short fibers. Its main products include recycled cotton, medium length, wool, hollow polyester short fibers, etc., with nearly a hundred product specifications and varieties. As a resource recycling enterprise, Qiusheng Resources also attaches great importance to environmental protection in the production process, voluntarily promoting clean production, and has passed the clean production acceptance and been rated as a "Guangdong Province Clean Production Enterprise". It is understandable for the enterprise to seek economic benefits, but what is commendable is that the enterprise takes the maintenance of the ecological environment as the premise, recycles social waste, uses technology to transform waste, creates new value, and pays attention to environmental protection in the production process, actively assuming the social responsibility of protecting the environment.At present, there are large leading enterprises in China's PET bottle production industry that have excellent PET bottle automatic production lines manufactured by well-known companies around the world (such as the fully automatic PET bottle production lines of ASB and Aoki Gu in Japan, SEDEL in France, and SIPA in Italy). At the same time, there are also a large number of small and medium-sized enterprises that use various simple and practical bidirectional PET blow molding machines with different degrees of automation designed and manufactured by China, presenting an unprecedented situation of colorful competition and prosperity.
PET recycled plastic can be used to make clothes, motorcycle helmets, fishing lines, and packing ropes. Or simply use it on food packaging materials, PET recycled plastic bottles can achieve unlimited recycling and reuse. This is an environmentally friendly technology within reach of our country. It is reported that PET recycled plastic bottles are expected to enter the Chinese market in the near future.
Due to the fact that the raw materials for plastic packaging come from petroleum, many developed countries have developed recycling and reuse technologies for plastic packaging in order to save resources. As early as 1991, recycled PET slices were already used for food packaging. The excellent barrier properties of PET material make it the most important packaging material for various carbonated beverages, fruit juices, dairy products, tea drinks, mineral water and other food and beverage products. In China, all PET plastic bottles are currently made from raw PET materials extracted from petroleum. The annual production of up to 3 million tons of PET plastic bottles consumes over 18 million tons of petroleum and also causes enormous environmental pressure. The recycling of PET recycled plastic bottles is beneficial for conserving resources.
Within the scope of Beijing, the total amount of PET plastic bottles discarded each year is as high as 150000 tons, which is about 6 billion waste plastic bottles, causing great harm to the environment. With the development of technology for manufacturing recycled PET slices, recycled food grade PET slices can be directly used for food packaging, achieving 100% infinite recycling. The recycling of PET recycled plastic bottles greatly saves the consumption of petroleum resources.
With the development of the domestic economy and the improvement of industry policies, the market potential of recycled PET products will gradually emerge, and more and more enterprises will enter the industry. In order to maintain their competitive advantage, enterprises must increase investment in scientific research and promote the upgrading of product structure. At the same time, pay attention to environmental protection during the production process, avoid secondary pollution, and truly achieve the unity of social and economic benefits.
