Eco Expo Asia 2025

RCRE has set up an exhibition booth with a start-up “Carbon Capture & Storage (CCS) Limited” at Eco Expo Asia 2025 to showcase the sustainable low-carbon construction materials and technologies. This event was held at the AsiaWorld-Expo on 28 – 31 October 2025. Prof. Shipeng Zhang (Associate Director of RCRE) has also been invited to be a speaker to present the developed low-carbon technologies for construction. 

Joint Seminar: The 3D Eco-Concrete Printing for Hong Kong’s Construction Industry

A joint seminar with Hong Kong Institute of Project Management (HKIPM), PolyU-NAMI 3D Concrete Robotic Printing Research Centre (RCC3D), BRE and CEE of PolyU, titled "The 3D Eco-Concrete Printing for Hong Kong's Construction Industry," was held successfully on 28 October 2025. The seminar featured insightful presentations from three distinguished guests: Dr Jacky Chung (RCC3D and RCRE Member), Ir Lucas Lam (RCC3D) and Dr Junli Liu (CEE). Following the seminar, attendees toured RCC3D’s lab to observe 3D concrete printing technologies in action.  

RCRE Director Partners with Industry to Convert Waste Glass into Low-Carbon Bricks for Central Mall Renovation

Ir Prof. Poon Chi-sun, Director of RCRE, has partnered with Gammon Construction to support Hongkong Land’s HK$7.8 billion “Tomorrow’s Central” initiative, which aims to renovate its shopping mall in Central. This project will transform demolition glass waste into partition bricks and low-carbon cement alternatives, with the goal of recycling 75% of the waste generated. The innovative technology grinds waste glass into powder to replace 20–30% of the cement in brick production, resulting in eco-bricks that are 10–20% stronger than conventional ones. With over 41 tonnes of glass already dismantled and more than 20,000 bricks expected to be produced, this approach offers a scalable solution for managing Hong Kong’s extensive glass waste and could be expanded to develop structural building materials in the future.   Online coverage (Chinese only): Ming Pao Daily News - https://polyu.me/4qnMOFr Hong Kong Economic Times - https://polyu.me/43oVvpc (subscription required) Headline Daily - https://polyu.me/4nlRr0d Wen Wei Po - https://polyu.me/4nl6yXQ Bastille Post - https://polyu.me/49ovAlc Macau Business - https://polyu.me/43B2X0v PC home - https://polyu.me/3L9A1X3 Sina HK - https://polyu.me/43wW9Ru Global News - https://polyu.me/3WWvQjW NetEase - https://polyu.me/4hmWmfP
