Recently, Yuantian Biotechnology (Tianjin) Co., Ltd. successfully passed the Global Recycled Standard (GRS) certification, becoming the first company in the world to achieve this honor with bio-based circular technology!

The Global Recycled Standard (GRS) is an internationally recognized certification system for recycled materials and sustainable development, established by Textile Exchange. It rigorously evaluates companies' comprehensive performance in areas such as the use of recycled materials, environmental management, and social responsibility. Obtaining this certification signifies that the company's production processes, waste management, and overall supply chain sustainability have reached internationally leading standards.

Yuantian Biotechnology has successfully achieved efficient degradation and infinite circular utilization of waste PET through its independently innovative bio-enzymatic regeneration technology. The attainment of this certification not only affirms the company's technical capabilities but also serves as authoritative endorsement for its "zero pollution, full circularity" development model.

Bio-Enzymatic Regeneration Technology
Breaking Industry Bottlenecks, Defining Future Standards

With the rapid global increase in plastic waste, leading to environmental pollution and resource wastage, the efficient recycling and reuse of waste PET plastics has become a global focus.

Compared to traditional recycling and regeneration methods, the core advantages of bio-enzymatic PET regeneration technology include:

✅ Green and Efficient: Utilizes highly efficient and specific PET-degrading enzymes to break down various waste PET materials—such as polyester fabrics, beverage bottles, and PET films—under normal temperature and pressure, with no secondary pollution.
✅ Infinite Circularity: Transforms waste PET into high-value, high-quality recycled rbPET, truly "turning waste into treasure" and enabling discarded plastics to circulate endlessly within the ecosystem.
✅ Low-Carbon and Energy-Efficient: Replaces high-energy-consumption, high-emission traditional industrial processes and indirectly reduces the carbon footprint across the lifecycle through resource recycling, with estimated emission reductions of up to 60%.
