PolyU Showcases Carbon-Neutral Construction Materials at Paris Exhibition

The Hong Kong Polytechnic University (PolyU) is presenting innovative carbon-neutral construction materials at its inaugural "Flying High" exhibition in Paris. Among these are CarbAggre, a customisable, carbon-negative material derived from construction and demolition waste, and a novel carbonation concrete coating technology designed to enhance concrete durability. These advancements are part of PolyU's broader commitment to sustainability in innovation, aiming to address environmental challenges within the construction sector.
CarbAggre: A Carbon-Negative Composite

CarbAggre represents a significant development in sustainable building materials. This material is engineered from construction and demolition waste, transforming potential landfill burden into a valuable resource. Its carbon-negative nature means that its production process sequesters more carbon dioxide than it emits, actively contributing to climate change mitigation efforts.
Enhanced Concrete Durability Through Carbonation Coating

PolyU is also exhibiting a advanced carbonation concrete coating technology. This innovation focuses on improving the longevity and resilience of concrete structures. By applying this coating, the university aims to reduce the need for frequent repairs and replacements, thereby extending the service life of buildings and infrastructure and contributing to resource efficiency.
Broader Sustainability in Innovation Theme

These construction material innovations are featured under the "Sustainability in Innovation" theme of the "Flying High" exhibition. This theme highlights PolyU's dedication to developing solutions that promote environmental responsibility and combat carbon emissions. The exhibition, running until July 1, 2024, serves as a platform to share these advancements and foster international dialogue on sustainable practices.
