Media report: PolyU and Hongkong Land collaborate to apply waste glass in low-carbon construction materials promoting a sustainable environment

27 Oct 2025

Research and Innovation

The Hong Kong Polytechnic University (PolyU) has partnered with Hongkong Land Holdings Limited to develop eco-blocks made from glass waste for use in renovating the enterprises’ properties, promoting green building initiatives.

Prof. Poon Chi-sun, Distinguished Research Professor in the Department of Civil and Environmental Engineering, and Michael Anson Professor of Civil Engineering of PolyU, and Director of the Research Centre for Resources Engineering towards Carbon Neutrality, and his team have developed eco-blocks made from recycled glass waste. The blocks not only help reduce carbon emissions during construction but also offer superior strength and durability compared to traditional bricks. The new blocks are 10 to 20% stronger than conventional bricks, and waste materials from existing properties are sufficient to produce over 20,000 eco-blocks, demonstrating a practical and scalable solution for green renovation.

This partnership exemplifies how academic research can drive real-world applications, turning waste into valuable resources and advancing the construction industry towards carbon neutrality. Prof. Poon’s work continues to connect academia and industry, delivering innovative solutions for a greener future. It effectively transforms construction waste into valuable resources, enabling more environmentally friendly and efficient building practices.
