Wedoany.com Report-Oct. 25, Hongkong Land, a major property developer, has launched an innovative initiative to recycle tempered and laminated glass waste from shopfronts and curtain walls as part of its $400 million upgrade of the 12-building Landmark portfolio in Hong Kong’s Central district. The project, named Tomorrow’s Central, is a three-year effort set to conclude by 2027 and includes facade enhancements, retail space reconfigurations, lobby relocations, and the addition of new exit staircases.

The 12-building revamp in Hong Kong’s Central district will create some 50 tonnes of unwanted tempered and laminated glass, and local landfill sites are nearly full

This pioneering effort involves a collaboration with Gammon Construction, the project’s main contractor, and Hong Kong Polytechnic University (PolyU). The initiative introduces circular-economy principles to the construction sector by repurposing glass waste. During the 2023 pre-construction phase, Gammon identified approximately 50 tonnes of glass, including shopfronts, facades, and curtain walls, that would be removed during the upgrade.

Currently, Hong Kong lacks a viable method for recycling tempered and laminated glass, which typically ends up in landfills. With the city’s landfill sites projected to reach capacity by 2026, this poses a significant challenge. To address this, the partnership aims to grind the glass into aggregate for producing low-carbon concrete partition blocks, which will be used directly in the Tomorrow’s Central project. These blocks will meet the standards set by Hong Kong’s Buildings Department, marking a first for the city.

“At Hongkong Land, we’re committed to building a circular economy, one where waste is not a burden but a resource,” said Hongkong Land’s chief executive Michael Smith. “This initiative provides scalable, replicable models sure to shape construction practices in Hong Kong and beyond.”

Gammon’s chief executive Kevin O’Brien emphasized the importance of sustainability, stating: “Sustainability must be embedded from the earliest stages of construction. This commercial-academic partnership will create meaningful industry-wide change.”

Professor Chi Sun Poon, director of the Research Centre for Resources Engineering towards Carbon Neutrality at PolyU, highlighted the project’s potential, saying: “This initiative will transform how tempered and laminated glass waste is handled.”

The project is particularly significant given Hong Kong’s ageing building stock, with thousands of structures over 50 years old requiring upgrades. By recycling glass waste into usable construction materials, the collaboration sets a precedent for sustainable practices in the region’s construction industry. This approach not only reduces landfill pressure but also promotes resource efficiency, aligning with global efforts to minimize environmental impact.

The Tomorrow’s Central project demonstrates how innovative partnerships can address urban challenges while advancing sustainable development. By integrating recycled materials into a major redevelopment, Hongkong Land, Gammon Construction, and PolyU are paving the way for scalable solutions that could influence construction practices across Hong Kong and beyond, fostering a more sustainable future for the industry.
