In the ever-evolving landscape of construction, the shift towards a circular economy represents not just a trend but a necessary pivot for sustainable development. Recently, I had the pleasure of sitting down with Alex Spencer, a project manager with over a decade of experience in sustainable construction, to discuss the intricacies of implementing circular economy principles in the real world.

Our conversation unfolded with Alex recounting his latest project — an ambitious office development in the heart of Manchester. “The first step,” he emphasised, “is always to assess the scope of the development. This assessment is crucial as it dictates the appropriate methodology for a circular approach.” According to Alex, this means understanding the unique requirements and potential of each project, which can often differ vastly even among similar types of developments.
“Office developments,” Alex noted, “often present a unique set of challenges and opportunities for circularity.” In his experience, these projects tend to have a higher turnover of tenant needs, which can align well with the adaptability that a circular economy aims to achieve. “We start by mapping out the lifecycle of the building materials,” he explained. “This involves a thorough analysis of what can be reused, repurposed, or recycled, and what needs to be sourced sustainably.”
Alex shared an enlightening anecdote about integrating urban mining and material passports into the project. “We treated the existing structure as a treasure trove,” he said with a smile. “The notion of urban mining was initially met with scepticism, but once we started cataloguing materials for reuse, it was like opening Pandora’s box of possibilities.” Material passports, documents that record the origin, composition, and potential for reuse of building materials, became an invaluable tool in their arsenal. “These passports changed the game for us. They allowed us to view the building’s components not as waste but as valuable resources.”
One of the significant challenges Alex encountered was the lag in industry standards and expectations concerning the circular economy. “Industry practice hasn’t fully caught up with the ideals,” he admitted. “There’s a lot of enthusiasm, but the quantification and logging policies are still in their infancy.” Despite these challenges, Alex pointed out a growing motivation among developers and owners to incorporate circular principles into their projects. “It’s a slow burn, but the appetite is there,” he said confidently.
The conversation then veered towards the broader implications of a circular economy in construction. Alex highlighted that this approach isn’t just about sustainability; it’s also a robust business strategy. “The UK Green Building Council’s report from 2019 really hit the nail on the head,” he remarked. “A circular economy can lead to a more reliable, lower-risk cash flow. It builds long-lasting relationships with clients and de-risks project pipelines.”
Throughout the discussion, Alex was candid about the learning curve involved. “Each project is a lesson,” he said. “The complexity of integrating circular economy principles means you’re constantly adapting and evolving your approach.” He underscored the importance of collaboration and knowledge sharing within the industry. “We need to be more open about what works and what doesn’t. Sharing successes and failures helps the entire industry move forward.”
As our conversation drew to a close, Alex reflected on the future of construction and the circular economy. “I think we’re at the cusp of a significant shift,” he mused. “As more stakeholders recognise the economic and environmental benefits, circularity will become the norm rather than the exception.”
In recounting Alex’s experiences, it becomes clear that while the road to a fully circular economy in construction is fraught with challenges, it’s also paved with opportunities. For those in the industry, the message is clear: assess the scope, embrace innovation, and be prepared to adapt. As Alex so aptly put it, “It’s not just about building structures; it’s about building a sustainable future.”
For those considering a foray into circular construction, the key takeaway is to start with a comprehensive assessment and remain flexible in your methodologies. By doing so, you can unlock the potential of a circular economy to not only meet but exceed today’s sustainability goals.
