首条生物酶法5000吨/年rPTA产线落地

Core Viewpoint - The signing of the investment cooperation memorandum between Yuan Tian Biotechnology (Tianjin) Co., Ltd. and the Tianjin Economic and Technological Development Zone marks the official launch of the world's first 5,000-ton bio-enzyme method for recycling purified terephthalic acid (rPTA) project in Tianjin [1] Investment and Project Details - The total investment for the project is approximately 150 million yuan, with production expected to commence by mid-2026 [1] - The project aims to process about 10,000 tons of waste textiles annually [1] Technology and Production Efficiency - The bio-enzyme recycling technology offers better raw material compatibility, supporting both post-consumer recycled (PIR) textiles and post-consumer recycled (PCR) blends [1] - The PET degrading enzyme developed by Yuan Tian Biotechnology has increased enzyme activity by 2,000 times, achieving a significant efficiency leap with an 8-hour degradation time [1] Product Quality and Cost Efficiency - The quality of the products (rPTA and rEG) is comparable to virgin materials, achieving "zero perceptible difference" from petroleum-based materials [1] - The bio-enzyme method utilizes an all-aqueous system, operates at room temperature and pressure, and does not require organic solvents, resulting in lower energy consumption and significantly reduced costs [1] Environmental Impact and Future Plans - Once the 5,000-ton rPTA production line is established, the company will focus on recycling and regenerating post-consumer waste textiles as a key raw material source, creating a closed-loop industry chain from "waste textiles to rPTA/rEG to rbPET to recycled fibers" [1] - The company plans to further develop a 100,000-ton/year bio-enzyme method rPTA production line in the future [1]
