[0002] As we all know, with rising environmental awareness, the reuse of industrial and consumer waste has become a significant issue and business opportunity. Global annual production of polyester products currently reaches approximately 70 million tons. Bottle polyester, which accounts for 30% of the total, now has a comprehensive recycling mechanism.
