To effectively mitigate the global greenhouse effect, the industry must look beyond traditional "emission reductions" and prioritize Carbon Capture and Utilization (CCU).
Unlike Carbon Capture and Storage (CCS), which focuses on permanent underground sequestration, CCU views captured CO2 as a valuable resource. Through advanced technology, it transforms CO2 into high-value everyday materials while maintaining carbon neutrality throughout the production process—turning the vision of a truly sustainable closed-loop cycle into reality.
Reducing reliance on fossil fuels by utilizing renewable plant-based or biological sources to minimize the carbon footprint right from the source.
Integrating post-consumer and post-industrial waste for recycled regeneration, operationalizing a sustainable, closed-loop production philosophy.
Yie-Cheng has entered into a formal cooperative agreement with global chemical leader
Aether Industries Limited to co-develop technologies that polymerize captured carbon dioxide into premium polycarbonate raw materials. Leveraging our specialized technical expertise, these materials are engineered into our advanced polycarbonate PU membrane (PURE). By laminating this innovative membrane with Recycled Polyester fabrics, we have created an epoch-making solution for high-performance outdoor textiles.

Precisely capturing carbon dioxide (CO2) from stationary industrial sources to prevent atmospheric release, operationalizing our commitment to eco-friendly principles.
Partnering with Aether to polymerize captured CO2 into Polycarbonate Polyols, successfully transforming emissions into high-value chemical matrices.
Engineered with proprietary technology, our premium waterproof and moisture-permeable PURE PU membrane is laminated with recycled polyester to power elite-tier performance apparel.
