From Anhui to Sanming, Regenerated Polyester Project “Taking the Lead”

In 2025, the "champion-based" model for manufacturing innovation will shift its focus towards the field of recycled materials. Recently, Anhui and Sanming have intensively announced key research tasks, with three major projects directly targeting the critical issues of "high-value utilization of waste plastics," "carbon fiber recycling," and "functionalization of polyester fabrics." These initiatives aim to break through industry technical bottlenecks and support the "dual carbon" goals.

Anhui Makes a Strong Move: Three Major Recycled Materials Projects Set the Benchmark as "Domestic Leaders"

On September 3rd, the Anhui Provincial Department of Industry and Information Technology released the announcement of the guiding directory for the 2025 manufacturing "Revealing the List and Taking Command" talent recruitment and special research projects. After procedures such as enterprise applications, city recommendations, and expert evaluations, 328 tasks are proposed to be included in the 2025 manufacturing "Revealing the List and Taking Command" directory. Among them, 3 projects on recycled polymer materials have clear technical indicators, covering the three fields of automotive, high-end materials, and textiles.

Serial Number 258: Research and Application of High-Value Recycling and Thermochemical Conversion Integrated Utilization Technology for Automotive Waste Plastics

1. The accuracy of waste plastic identification and sorting is ≥95%;

The retention rate of mechanical properties for high-performance recycled plastics is ≥85%, and the VOC emission meets automotive standards.

The thermochemical conversion rate of plastics is ≥90%, and the yield of combustible gas/hydrogen is ≥60%.

4. The proportion of recycled plastics used in the whole vehicle is ≥25%;

Meet the material safety and environmental protection requirements of the EU ELV Directive and REACH regulations.

Serial Number 259: Technical Research on High-value Recycling of Waste Carbon Felt for Secondary Formation of Carbon Fiber Felt and Preparation of Porous Carbon Bricks

Technical specifications for secondary felting of recycled carbon fiber: density lower than 0.25 g/cm³ to ensure the lightweight characteristics of the carbon fiber felt; compressive strength higher than 10 MPa to guarantee a certain level of compressive resistance; product yield higher than 80% to control production losses and ensure production efficiency.

Technical specifications for preparing porous carbon bricks from recycled carbon fibers: The density should be between 0.9 - 1.1g/cm³ to ensure moderate product density; the flexural strength should be higher than 8MPa, and the compressive strength should be higher than 10MPa to meet certain strength requirements; the yield should be higher than 60% to balance production efficiency and quality.

Serial Number 260: Collaborative Research on Key Technologies and Industrialization Demonstration of High-Quality and Functional Recycled Polyester Fiber Fabrics

This project breaks through the key technological bottlenecks of recycled polyester fibers: Sub-project 1 develops recycled polyester fibers with dope-dyed technology in more than four colors, achieving a strength retention rate of ≥90% (national standard GB/T3923.1-2013), which is 5% higher than the industry average. Sub-project 2 pioneers the technology of bio-based nano-finishing agents, achieving an LOI value of 33 vol%, V-0 level flame retardancy, an antibacterial rate of >99%, with 90% retention after 30 washes, and a surface resistance of 10^6-10^11Ω. Innovative development has formed a core technology system (1 new product, 3 new processes, 4 new devices), with 25 patents filed (including 2 PCT international applications), and 2 enterprise standards established, along with the construction of dual demonstration lines for spinning and fabric. Compared to the traditional processes of Sanfangxiang Group, the chemical recycling high-precision filtration device and bio-based modification technology significantly enhance product stability and functional durability.

After reaching full production, it is expected to generate an additional output value of 300 million RMB, boost the recycling rate of waste textiles in Anhui by 15%, form a 1 billion RMB circular industry cluster, reduce CO2 emissions by 80,000 tons annually, and contribute to the goals of a "zero-waste city" and "dual carbon" targets, with technical indicators reaching the leading level domestically.

Why have recycled materials become the focus of "open competition for leadership"?

"The 'Revealing the List and Taking Command' system, also known as the technology reward system, addresses the disconnect between scientific research and application of results through an open collaborative model of 'heroes regardless of their origins.' Since it was first proposed in the 2020 government work report, it has become a key mechanism for overcoming 'bottleneck' technologies. Under the current policy direction of 'dual carbon' and 'waste-free cities,' recycled materials are a core approach to solving the 'resource shortage + environmental pressure' issue. The fields of waste plastics, carbon fiber, and polyester, which Anhui and Sanming are focusing on, are pain points in traditional recycling due to 'low utilization and low added value.' Through the open approach of 'Revealing the List and Taking Command,' not only can the implementation of technology be accelerated, but it can also promote the transformation of the recycling industry from 'low-cost recovery' to 'high-value upgrading.'"
