Recycling Applications: Plastic Bottles Transform the Whole Process

Piles of used beverage bottles, rotten plastic, these headache-causing white pollution can weave soft and warm colored blankets. The Binzhou Longfu Huaneng Technology Co., Ltd. located in the high-efficiency eco-economic zone of the Yellow River Delta, through technological innovation, uses waste plastic as raw material for textile production, truly realizes turning waste into treasure, saves energy and reduces emissions, and establishes a resource-saving type. New model of business.

It is understood that Longfu Huaneng Technology Co., Ltd. was established in 2006, in just 5 years, from a small chemical fiber plant with fixed assets of several million yuan and less than 100 employees, it has developed into a fixed assets of 1 billion yuan. The large-scale chemical fiber textile enterprises with more than 3,000 employees employ the complete energy-saving environmental protection industry chain and attach importance to technological innovation.

“We are the only company in the world that has a complete industrial chain for waste plastic bottle recycling, bottle chip processing, recycled polyester fiber production, and recycled polyester textile weaving. The entire company can annually produce 80,000 tons of recycled polyester filament and 60,000 tons of recycled Polyester blanket.” Duan Jianguo, Chairman of Longfu Company, proudly told the reporter that at present, Longfu Company can recycle 100,000 tons of used plastic bottles in a year, which is equivalent to processing a waste bottle of 30 million people in the city. Save 150,000 tons of oil, energy equivalent to 210,000 tons of standard coal. The entire company has formed a complete organic chain from the waste bottle acquisition, bottle chip processing, polyester spinning, to the final weaving of the blanket.

Since 2006, Longfu Company has, after arduous research and development, finally overcome the technical difficulties in the production of polyester filaments from the use of waste PET bottles, and has therefore won 8 national patents, becoming the first domestic company to use 100% used polyester bottles. Tablets for the production of recycled polyester filaments. “Twenty years ago, we had the technology to recycle used PET bottles in China, but all of them produced low value-added products. Our biggest breakthrough was to achieve high value-added production.”

"These old PET bottles come from old beverage bottles. The plastics themselves have a compound food safety level, so there is no difference between the blankets produced from them and the same kind of polyester blankets." Duan Jianguo said that the use of waste Ester-flaky tablets not only achieve environmentally friendly recycling, but also save a lot of raw material costs for the company and make the products more advantageous.

"Using waste plastic bottles, the cost of raw materials will be saved by around 2,600 yuan per ton per tonne. Even if we add up the technical cost and the benefit to the downstream customers, we can have nearly 1,500 more than the textile enterprises that use only raw petroleum chips. The advantages of Yuan.” Duan Jianguo said that it is precisely because of its huge technological advantages that “recycled polyester filament” produced by Longfor Company has been appraised as a “National Key New Product”, and the company has also been named “China's Chemical Fiber Industry Circular Economy Demonstration”. "Enterprises" and "Shandong Province Provincial Key Technology Center."

Not long ago, Longfu also cooperated with Donghua University to establish a joint research and development center. In the future, it will tackle the issues of “flame-retardant modification of renewable polyesters” and “spinning of polyester fibers for bottle-spun artificial fur”. And will continue to increase the development of renewable flame-retardant textile products, making recycled textile products to obtain a broader use of space, thus promoting the overall progress and sustainable development of the recycling industry.
