Pade Technology Co., Ltd. was established in 2023 in collaboration with Professor Jen-Jie Chieh at Institute of Electro-Optical Science and Technology, National Taiwan Normal University. The company has developed an intelligent sorting system that utilizes near-infrared (NIR) spectroscopy for fast and non-contact identification of waste textile materials and AI machine learning for high accuracy. This technology assists textile recycling operators in precise material classification and provides quality recycled textile “waste” for chemical fiber factories in textile circular economy. The European Union Carbon Border Adjustment Mechanism (CBAM) is set to be implemented in 2026, and fashion brands and retailers are jointly committed to increasing the use of recycled materials. Thereby establishing a closed-loop textile circular economy is imperative.
