On August 12, 2025, Yuantian Biotechnology (Tianjin) Co., Ltd. and Tiandai Environmental Protection Materials (Tianjin) Co., Ltd. reached a strategic cooperation agreement, aiming to break through the recycling bottleneck of PCR (post-consumer waste textiles) and create a complete closed-loop system from collection to reycle application.  

 

 Post-Consumer Waste Textiles:  

 The Last "Hard Nut to Crack" in the Recycling Industry  

 

It is estimated that China generates over 56 million tons of waste textiles annually, yet the recycling rate remains below 20%. Among these, post-consumer waste textiles (such as discarded clothing and home textiles from ordinary consumers) are particularly challenging to recycle and regenerate.  
 

 

On one hand, post-consumer waste textiles come from scattered sources like households and individuals, lacking a centralized collection system. They rely on fragmented donation bins and community collection points, resulting in low collection efficiency and high transportation costs.  

 

On the other hand, post-consumer clothing is often made of blended materials (e.g., cotton + polyester) and may be contaminated with stains, chemicals, or microorganisms (such as mold). Traditional recycling technologies cannot separate different materials, leading to unstable performance in recycled products.  

 

How can this challenge be addressed? Yuantian Biotechnology and Tiandai Environmental Protection have proposed an innovative solution!  

 

A Breakthrough Moment:  

Three Revolutionary Advances in Bio-Enzymatic Method  
 

 

01 One-Step Enzymatic Hydrolysis**  

A single enzyme with dual functions efficiently produces rPTA and rEG monomers, replacing the traditional "two-enzyme, two-step method." This enables a simpler, faster, and greener mass-production revolution.  

 

02 Solving the Challenge of Blended Fabric Recycling**  

The bio-enzymatic recycling technology stands out for its exceptional ability to degrade blended fabrics. It can precisely break down PET components in complex blended materials like polyester-cotton and polyester-ammonia, offering极强的raw material adaptability.  

 

03 Product Quality Comparable to Virgin Materials**  

The bio-enzymatic recycling technology breaks down waste textiles into rPTA and rEG monomers, which are then polymerized into再生PET. The quality and performance of the recycled products are on par with virgin materials, achieving true infinite recycling + upcycling.  

A Powerful Collaboration:  

Revolutionizing the Recycling of Post-Consumer Waste Textiles  

 

Tiandai Environmental Protection is Tianjin’s first recycling technology company dedicated to the circular reuse of waste textiles. It is committed to building a full industrial chain circular economy system for waste textiles and promoting green and low-carbon transformation in the textile industry. By leveraging AI-enabled smart manufacturing spectral sorting recognition and collaborating with intelligent manufacturing robots, the company achieves efficient sorting, cutting, crushing, and separation of blended materials in post-consumer waste textiles.  
 

 

This powerful collaboration between Tiandai Environmental Protection and Yuantian Biotechnology will focus on the complete value chain of post-consumer waste textile recycling: Tiandai Environmental Protection will handle the collection and sorting end, while Yuantian Biotechnology will focus on the recycling technology end. Together, they will form a green consumption closed loop of "collection-recycling-application," improving the recycling rate of post-consumer waste textiles.
