淘汰的旧衣服、床单都去哪里了？也许不久后，它们经过高科技"再生"，将成为新的产品重回市场。 在日前举办的2025循环创新·时尚大会上，中国纺织工业联合会会长孙瑞哲表示，从2005年至2024年， 纺织行业单位产值能耗下降超过65%，废旧纺织品回收利用量年均增长12%，再生纤维年使用量突破 300万吨。亮眼成绩单的背后，是纺织行业对循环经济的积极探索与持续深耕。 积极推进循环利用 在通用技术中纺院（天津）科技发展有限公司，一批色彩各异的废旧T恤和床单被集中投入反应装置， 经过快速溶解降解、固液快速分离和漂白脱色，涤纶和棉轻松分离，顺利进入回收循环流程，成为再生 纺织产品的新原料。 通用技术中国纺织科学研究院有限公司功能纤维研究所教授级高级工程师金剑介绍，在废旧纺织品中， 涤纶和棉制品占比高、回收难，尤其是涤棉混纺产品成分复杂、分离困难，成为再生利用中的"硬骨 头"。用传统方法回收，面临效率低、能耗高、污染大等问题。如今，这项化学法回收技术为破解难题 提供了绿色、低碳方案。 当前，我国每年产生的废旧纺织品总量庞大，传统处理模式面临不小压力。如何实现从"废旧衣"到"新 原料"的高质量循环，成为行业破局关键。中国纺织 ...

Core Viewpoint - The Chinese textile industry is actively transitioning towards a circular economy, with significant reductions in energy consumption and increases in recycling rates, driven by policy initiatives and industry collaboration [1][2][3] Group 1: Industry Achievements - From 2005 to 2024, the energy consumption per unit of output in China's textile industry has decreased by over 65% [1] - The annual growth rate of recycled textile materials is 12%, with the usage of regenerated fibers exceeding 3 million tons [1] - In 2024, cotton production is expected to exceed 6 million tons, synthetic fiber production is close to 70 million tons, and fabric production will surpass 30 billion meters [2] Group 2: Policy and Market Dynamics - The implementation of the "2025 target" aims for a 25% recycling rate of used textiles and a regenerated fiber output of 2 million tons [2] - Policy guidance is crucial for the textile industry's circular economy, transitioning from spontaneous exploration to a phase driven by policy and market response [2] - Future policies will focus on standardization, data sharing, and financial support to enhance the recycling system and expand applications for regenerated fibers [2] Group 3: Challenges in Recycling - Currently, only about 2% of waste textiles are recycled for industrial use, with 1% achieving closed-loop recycling [3] - The complexity of separating blended fabrics, particularly polyester and cotton, poses significant challenges for recycling efforts [3] - The predominant recycling method remains physical processing, which produces low-value products, while chemical recycling faces high costs and complexity [3] Group 4: Innovations and Future Directions - The introduction of Digital Product Passports (DPP) aims to provide traceability for fibers throughout their lifecycle, enhancing recycling efforts [3] - The goal is to enable garments to be fully recyclable multiple times, with each cycle adding new functionalities [4] - Successful exploration in China's textile industry serves as a valuable reference for global industry development, although significant challenges remain in realizing the value of the circular economy [4]

Core Insights - The conference on Digital Product Passport (DPP) V1.0 aimed to establish an international cooperation framework for product lifecycle management, focusing on green and sustainable supply chain practices [1][2] - The MA-DPP Universal Framework V1.0 was launched as the world's first DPP framework, designed to support a collaborative and trustworthy data infrastructure for global supply chains [3] Group 1: Digital Product Passport Development - The DPP serves as a digital carrier throughout the product lifecycle, emphasizing its growing importance in international cooperation for global development [2] - The steel industry is among the first sectors in the EU to implement the DPP, with a public service platform launched to support green initiatives for Chinese steel enterprises [3] Group 2: International Collaboration and Standards - Experts from various international organizations discussed the progress of the EU's DPP system and its role in lifecycle management standards, providing a global perspective on DPP standardization [4] - Strategic partnerships were formed between organizations like Zhongguancun Institute and Siemens (China) to develop ecological solutions for battery passports and carbon footprints [5]
