Building Circular Cities: Digital Marketplaces Driving Construction Material Reuse

The future of net-zero, resource-efficient cities lies in how effectively we manage construction materials. This session explores how digital marketplaces are redefining resource flows by connecting stakeholders across the supply chain to exchange, repurpose, and reuse construction materials. Through transparent data sharing, traceability tools, and collaborative digital platforms, these systems enable smarter procurement decisions and measurable carbon savings. Industry leaders and technology innovators will discuss how such solutions enhance material visibility, reduce waste, and foster trust among contractors, developers, and recyclers. The conversation will highlight practical pathways for building circular economies across urban infrastructure — driving both environmental and economic value on the road to net-zero cities.

Session Learnings:

• Discover how digital marketplaces and platforms are enhancing transparency, traceability, and efficiency across Hong Kong’s construction supply chain.
• Learn how data-driven material management supports waste reduction, carbon savings, and smarter procurement decisions.
• Explore successful examples of circular construction enabled by technology, collaboration, and innovative business models.
• Understand the critical role of industry-wide partnerships and leadership in accelerating the transition toward circular, net-zero cities.
• Gain insights into how Hong Kong’s construction sector is leveraging digital transformation to build a more sustainable and resource-efficient urban future.

Post-Event Actions:

• Assess current material management practices to identify opportunities for integrating circular principles and digital tracking tools.
• Initiate collaborations with industry partners and digital solution providers to pilot material exchange or reuse initiatives.
• Develop internal policies or guidelines to promote data transparency and material traceability across project lifecycles.
• Incorporate circular procurement criteria and reuse targets into sustainability strategies and tender frameworks.
• Leverage learnings from the session to strengthen organisational readiness for Hong Kong’s transition to a circular, low carbon construction economy.
