About
Dr. Andrew Chun Yong Ngo is a leading researcher at the forefront of sustainable materials management and advanced recycling technologies. His work primarily focuses on the application of multispectral and hyperspectral infrared imaging to revolutionize plastic waste sorting and recycling—a critical challenge given that Singapore alone generated over 982,000 tonnes of plastic waste in 2021, with a recycling rate of just 6%. Dr. Ngo’s major contribution lies in developing non-destructive, high-throughput imaging methods that can accurately identify and separate different polymer types, even from complex mixed waste streams. This innovation directly addresses the inefficiencies of conventional sorting, which often hampers recycling rates for plastics compared to materials like ferrous metal (99% recycling) or paper (39%). His most cited 2024 paper on this topic has already garnered attention for its practical potential to boost circular economy efforts. By bridging spectral analysis with real-world waste management, Dr. Ngo’s work offers a scalable solution to one of the most pressing environmental crises, positioning him as a key voice in the transition toward zero-waste systems.
