RCRE-led Green Building Material Technologies to be showcased at InnoCarnival 2023

Two advanced technologies from RCRE including the eco-cements synthesised from recycled solid wastes, and the eco-friendly radiative cooling coating UmiCoolTM, will be showcased at the InnoCarnival 2023 to be held from 28 October to 5 November 2023 at Hong Kong Science Park. The eco-cements developed by Ir Prof. Chi-sun Poon, RCRE Director, and his team, are produced from solid wastes including waste concrete, waste incineration ash, and waste glass. These eco-cements can capture, mineralise and store the carbon dioxide gas in the atmosphere, while enhancing the hydrophobic performance of concrete, hence greatly reducing the risk of flooding in extreme weather. The cooling coating UmiCoolTM  developed by Prof. Jianguo Dai, RCRE Member, and his team, uses the principle of radiative cooling to cool the surface and interior of buildings or infrastructure under direct sunlight during the day. It can reduce the surface temperature by up to 6°C as compared to the ambient temperature without consuming any electricity.   Online coverage (Chinese only): Oriental Daily News - https://polyu.me/3tuzdDs Wen Wei Po - https://polyu.me/3FjcKvW
