Circular Economy
The built environment needs to move away from the linear economy and embrace circularity. This will reduce waste, carbon emissions and our impact on the natural world.
The built environment needs to move away from the take-make-waste economy. For a sustainable future, a regenerative, circular economy that rewards the reuse of finite materials and resources must take its place.
What is the Circular Economy?
At its simplest, the circular economy prioritises the reuse of materials, preventing the over extraction of natural resources and the number of usable materials that end up in landfill. More widely, it’s an economic model that builds overall system health by gradually decoupling economic activity from the consumption of finite resources. Its visionary principles consider a different way of doing business, placing more importance on regenerating nature, carbon reduction and sustainable resource management than our current system. In practice, it can look as small as a refill hub for groceries in a commercial development, or be more significant like retaining a building’s structure and utilising second hand steel.
Circular Economy Principles
But for practitioners in the construction industry what does following the circular economy look like?
First laid out in our 2019 Circular economy guidance for construction clients the Circular Economy principles for buildings demonstrate how to build circularity in at each lifecycle stage.
Maximise reuse (including refurbish and repurpose)
A. Reuse the existing asset B. Recover materials and products on site or from another site C. Share materials or products for onward reuse
Design buildings for optimisation
A. Design for longevity B. Design for flexibility C. Design for adaptability iv. Design for assembly, disassembly and recoverability
Use standardisation
Standardised, modular elements in buildings are created with less waste and are easier to reuse.
Products as a service
Creating payment systems whereby materials are treated as a service – the contractor pays for the service of using materials not for the materials themselves.
Minimise impact and waste
A. Use low impact new materials B.. Use recycled content or secondary material C. Design out waste D. Reduce construction impacts
How can we enable a Circular Economy?
On an asset or business level the principles empower us to make the decisions that promote a circular economy. However, we need systems change so that all of industry can embrace circularity. As part of our Advancing Net Zero programme, our 2023 report System Enablers for a Circular Economy, identified eight enablers we can harness to create this shift.
- Collaboration & early engagement
- Second-hand materials market
- Design for disassembly/ design principles
- Green contracts and leases
- Tax & legislation
- Green financing
- Metrics, benchmarks, and indicators
- Education

Resource Use
In the UK, construction, demolition and excavation account for 60% of material use and waste generation. Meanwhile, prices of construction materials in the UK rose by 4.9% between 2017 and 2018. Adopting circular economy principles offers a €1.8 trillion opportunity to the EU between 2015 and 2030.
