RCRE showcased at the ReThink HK – Sustainable Business Forum & Solutions Expo 2025

ReThink HK 2025, organized by EnviroEvents HK and co-organized by the Business Environment Council, was held at the Hong Kong Convention and Exhibition Centre (HKCEC) on 11–12 September 2025. It is a flagship event for sustainable development and the largest event in the series of activities in Hong Kong Green Week 2025. RCRE was one of the exhibitors, showcasing innovative technologies related to low-carbon construction materials at ReThink HK 2025. Many visitors showed great interest in the low-carbon construction materials displayed at the RCRE exhibition booth. Ir Prof. Poon Chi-sun, Director of RCRE, also participated in two panel sessions at the event. In the session titled “Driving Circularity in Hong Kong’s Construction Industry,” Ir Prof. Poon highlighted his research on the valorisation of various types of waste as construction materials, as well as the regulatory and practical challenges that must be addressed before these materials can be widely adopted. Another session in which Ir Prof. Poon participated was “Integrating Technology and Sustainability for Urban Challenges: A Collaborative Vision for Hong Kong and the Greater Bay Area.” This session was co-organized by the Consulate General of France in Hong Kong and Macau, Business France, The French Foreign Trade Advisors (CCEF), and the Research and Innovation Office (RIO) and Policy Research Centre for Innovation and Technology (PReCIT) of PolyU. Ir Prof. Poon was invited to deliver a keynote presentation on net-zero concrete materials. He also shared his journey in translating research projects into real-world applications and discussed the technical challenges involved in adopting new construction technologies in Hong Kong and the Greater Bay Area during the panel discussion. Both panel sessions featured fruitful discussions.  

PolyU RCRE Seminar: Low Carbon Cements and Application in China

Dr Tongbo Sui, Vice President of Sinoma International Engineering Co., Ltd. under China Building Materials Group, delivered a seminar on the topic of “Low Carbon Cements and Application in China” on 21 August 2025.

RCRE Director edited a Special Issue of “Carbon Capture and Utilization (CCU) by Waste and Concrete”

The special issue of “Carbon Capture and Utilization (CCU) by Waste and Concrete”, edited by Prof. Chi Sun Poon (Director of RCRE), has recently been published in Cement and Concrete Composites, a top concrete materials journal. The special issue covers recent advances in the science and technology of using waste and concrete to capture CO2 as a means to reduce the carbon emissions of the global construction industry.  

RCRE Associate Director, Prof. Shipeng Zhang, was featured in Asian Power

Prof. Shipeng Zhang, Associate Director of RCRE and Assistant Professor in the Department of Civil and Environmental Engineering (CEE), was recently featured in an online interview by Asian Power, a quarterly publication for the power generation, transmission, and distribution industry in the Asia Pacific region. The conversation focused on the importance of waste-to-energy technologies in Hong Kong and the latest government policies and regulations supporting their development. Published on 8 July 2025 under the title “Waste-to-energy ties with mainland key to Hong Kong’s green goals,” the article highlights Prof. Zhang’s view that partnerships with Mainland China’s waste-to-energy incinerators are essential for Hong Kong to meet its zero-waste objectives. With the city targeting the closure of landfills by 2035, tapping into these cross-border facilities will be critical to achieving a sustainable waste management strategy.
