Recycling Of Waste Resources To Achieve Technological Progress

Shandong Yangxin Long Fu Ecological Technology Co., Ltd. is currently the largest enterprise in China, mainly focusing on the recycling of polyester resources. It has been developing the concept of "focusing on energy, protecting the environment, creating value and contributing to mankind". It has made great progress in the recycling and utilization of waste polyester bottles.

The company has independently developed the technology of producing polyester filament with waste PET bottle flakes, and has reached the advanced level of similar products in the world.

The technology has passed the appraisal of Shandong provincial scientific and technological achievements and the comprehensive utilization of Shandong provincial resources, and has obtained two invention patents and utility model patents. It has won the Shandong provincial science and technology progress award, the Shandong outstanding energy conservation achievement award, and Binzhou's major energy conservation achievement award.

By the end of 2007, the company was awarded the honorary title of "China chemical fiber industry circular economy demonstration enterprise" by China Chemical Fiber Industry Association.

According to Luo Guoliang, director of the company, the polyester filament produced by waste PET bottle flake has little difference in performance with that produced by conventional methods. However, compared with raw raw materials, the cost of producing polyester filament by waste polyester bottles is about 400~500 yuan per ton, and it can save 1.5 tons of oil and reduce carbon dioxide emissions by 77%.

At present, the annual production of polyester filament of dragon Fuhua chemical fiber is about 20 thousand tons, which can be used for making clothes, blankets and other textiles.

Long Fuhua chemical fiber company turned waste into treasure, opened up a new way to reuse waste plastics, protected the natural ecological environment, and realized the regeneration and recycling of waste resources.

The technology of producing polyester filament by using waste PET bottle flakes has broken the situation that domestic waste PET bottles can only produce low value-added short fiber products for many years. It not only effectively solved the problem of environmental pollution of waste bottles, but also reduced the consumption of petroleum resources by the chemical fiber industry, and realized the recycling of polyester resources. It has a positive and extensive demonstration and promotion significance for promoting the technological progress and industrial upgrading of regenerated textile.
