The True Cost of Waste

Summary

Waste remains one of the construction industry’s most entrenched challenges. Despite increased focus on sustainability, large volumes of valuable materials are still lost on projects every year, often because waste is designed into systems, contracts and behaviours from the outset.

At The True Cost of Waste, four speakers from across the supply chain explored the scale of the issue and why current practices often fail to support meaningful reduction. The discussion will touch on how waste is historically and currently generated, how it is priced into materials, procurement and waste management, and where responsibility for materials and surplus can become unclear on site.

The session examined how waste and resource use can be better tracked, measured and understood, revealing the true costs of waste, from lost labour and unnecessary disposal to embodied carbon and missed value. Speakers shared examples of tools, processes, training and software that support improved resource management, alongside real-world case studies showing how these approaches are being implemented.

Finally, the event highlighted the environmental, financial and social benefits of managing surplus more effectively, including working with suppliers and manufacturers on standardised solutions and take-back schemes, and using incentives and behaviour-change initiatives to ensure improvements are embedded and sustained.

The True Cost of Waste challenges the industry to look beyond what waste is assumed to cost—and to rethink how better resource management can deliver lasting value.buildings.
