The Hong Kong Polytechnic University (PolyU) is committed to advancing science‑driven solutions for some of the world’s most pressing environmental and urban challenges. From air quality and green construction to marine infrastructure, fire safety, and urban heat resilience, PolyU’s interdisciplinary research supported by the Research Grants Council delivers impactful innovations that enhance public health, safety, and long‑term sustainability.
- ️Air quality and public health
PolyU researchers are identifying key toxic components and emission sources of PM2.5 that are linked to chronic obstructive pulmonary disease, ischemic heart disease and other serious conditions. Their findings help shape health‑oriented air‑quality policies.
- Green construction
PolyU research has revealed an underestimation of soil emissions and an overestimation of biogenic emissions. These insights provide new insights to address winter haze and photochemical smog, particularly in China.
- Sustainable marine infrastructure
Using Fiber-Reinforced Polymer and Seawater Sea-sand Concrete instead of traditional steel, PolyU has developed ultra-strong seawater sea-sand concrete with a compressive strength exceeding 180MPa to enhance durability and sustainability in marine infrastructure.
- Smart fire safety system
PolyU’s AI-driven firefighting system, SureFire, provides real‑time monitoring of fire evolution and predicts critical events such as flashover or structural collapse. This system supports faster and safer emergency decision‑making.
- ️Urban heat and climate resilience
Through micro‑climate simulations, AI‑based optimisation, and wind‑heat‑moisture modelling, the PolyU research team supports the creation of healthy, resilient outdoor spaces integrated with urban design from the earliest planning stages.
Through these innovative initiatives, PolyU is not only pushing scientific boundaries but also working towards cleaner skies, safer cities, and a more livable future for generations to come.
