Core Viewpoint - The green polyester industry is on the verge of significant growth due to breakthroughs in new technologies that will expand the raw material base beyond bottle flakes, potentially opening up an additional 80 million tons of market space [1][2]. Industry Overview - The current processing level of the green polyester industry using physical methods is relatively mature, but it is limited to using bottle flakes as raw materials, primarily producing short fibers and bottle flakes [2]. - The annual production of polyester fibers is 79 million tons, with polyester bottle flakes accounting for approximately 32 million tons, representing about one-third of the total polyester production [1][2]. Technological Advancements - New technologies are expected to allow green polyester to completely replace virgin materials, thus significantly increasing the market potential [2]. - The recycling technology using biological methods is gaining attention, with companies like Carbios in France and Tianjin Yuantian Bio already making strides towards industrialization [3]. Market Dynamics - The polyester recycling system is relatively mature, with low-cost waste materials, which enhances the economic viability of developing new technologies [2]. - The flexibility of biological methods, which can produce recycled PTA and ethylene glycol, allows for broader applications beyond just polyester [3]. Investment Opportunities - Companies like WanKai New Materials and New Feng Ming are positioned well within the green polyester sector, with strategic investments and developments in bio-based materials [5][6]. - WanKai New Materials has established a forward-looking layout in both major development directions of green polyester and is expected to benefit from its parent company's investments [5]. - New Feng Ming, a leading polyester filament enterprise, is also investing in bio-based materials, positioning itself as a key player in the market [5]. Emerging Trends - The development of bio-based materials, such as the use of FDCA to replace PTA, is gaining traction, with significant investments from major players in the polyester supply chain [4]. - The commercialization of bio-based polyester applications is anticipated to accelerate, driven by clear application scenarios [4].
