Recently, the results of the "Top 10 Rubber and Plastic Technology Trends Case Selection Activity in 2025" (hereinafter referred to as the "Selection Activity") hosted by "Yashi Rubber and Plastic Network" were officially announced! Yuantian Biotechnology (Tianjin) Co., LTD. - The case of bio-enzymatic regeneration and industrialization of waste PET plastic has won the Excellence Award for its representative, forward-looking and innovative technology.
In this selection event, over a hundred enterprises submitted nearly 120 cutting-edge technology cases, covering ten major technological trend areas from material innovation to process upgrading, from intelligent manufacturing to green transformation. The participating enterprises include not only the top 50 global chemical companies but also specialized, refined, distinctive and innovative "little giants" and single-champion enterprises. After professional review and online voting by a review committee composed of over 20 scholars from universities, experts from industry associations and representatives of terminal enterprises, Yuantian Biotechnology (Tianjin) Co., LTD., one of the local innovative forces in China's recycled plastic industry cluster, stood out.
A technology is driving a market worth hundreds of billions of recycled PET
The rapid growth of global waste plastics has led to environmental pollution and resource waste. The efficient recycling and reuse of waste PET plastics have become a global focus.
According to data from Behers Consulting, the global recycled PET market size was 10.51 billion US dollars in 2024 and is projected to reach 13.817 billion US dollars by 2029. At present, it seems that none of the existing PET recycling technology routes can fully meet the market demand.
The enzymatic PET regeneration technology of Yuantian Biology has solved the problem of full life cycle management of plastic waste and can achieve the infinite recycling of waste spinning.
Regeneration of PET by biological enzyme method
Technological innovation demonstrates global potential
The key to the bio-enzymatic PET regeneration technology lies in the research and development of PET-degrading enzymes.
The technological breakthrough of the PET degradation enzyme developed by Yuantian Biology mainly lies in that it can endow one enzyme with two catalytic functions. The enzyme activity is 1920 times higher than that of natural enzymes, and the thermal stability is improved by 20℃. It can degrade various PET wastes into monomers (rPTA and rEG) under normal temperature and pressure conditions, and then polymerize to generate food-grade rbPET. Realize the unlimited recycling of PET plastic.
This technological breakthrough of "Made in China" marks that our country has reached the global forefront in the field of bio-plastic recycling.
Multi-party collaboration promotes the sustainable development of the industry
The governance of plastic pollution requires collaboration throughout the entire industrial chain. Breakthroughs in green technologies such as bio-enzymatic recycling will inject new impetus into the plastic recycling industry under the "dual carbon" goals.
At present, the company has built a ton-level industrial production line and has taken the lead in completing a closed-loop recycling system in the textile field. It has completed a series of verifications of r PTA - rb PET - spinning - weaving - ready-made garments and shoes, and has made in-depth breakthroughs in the high-end polyester field, automotive and packaging fields, completing the verification of industrial filament degradation in automotive airbags. Produced the world's first PET bottle for enzymatic regeneration of waste textiles.
The textile industry has achieved a closed-loop circulation
From recycling to regeneration, from materials to the end.
The bio-enzymatic regeneration technology of Yuantian Biology is reshaping the sustainable development path of the plastic industry.
The success of this case not only demonstrates the enterprise's innovative strength in the field of green technology, but also provides a practical Chinese solution for global plastic pollution control!
