New research launched by Grosvenor today shows that just 24% of built environment firms including architects, developers, construction, contractor and demolition firms have policies specifying material re-use targets.
The building and construction sector uses half of all new resources and generates more than a third of all waste in the EU*. To adapt buildings to new uses and meet the needs of growing populations without over exploiting natural resources, circular economy principles must be adopted at scale.
In February 2021, Grosvenor surveyed 120 professionals involved in the life cycle of buildings to understand the prevalence of material re-use and opportunities to scale circular economy practices.
88% of respondents stated their firms have an environmental sustainability policy. Of these, only 27% have a construction waste target that specified material re-use goals and 17% had no target to reduce construction waste at all.
However, 55% of participants have been involved in projects where materials from elsewhere were re-used and 62% said they are currently working on projects that could contribute materials into a second-hand market. 52% said they would be willing to receive materials in a current project.
Key barriers to supplying materials included concerns over liability, lack of a material re-use network and storage and access issues. The most cited obstacles to re-using materials included quality and consistency of materials, insurance, risk and lack of certainty over availability of materials.
Grosvenor is seeking to boost circular economy practices in the built environment by trialling a second-hand market for materials in Central London. In partnership with Elliott Wood, Orms, ARUP and HETA, Grosvenor is also increasing opportunities for learning and knowledge sharing. The first step is a range of guides addressing the key barriers identified in the research.

Steve Gilchrist, Project Director, Grosvenor commented: "Material re-use is the next chapter in sustainable design and construction. In London every year hundreds of buildings are designed, but to make way for them many must also be demolished - often this happens without due attention paid to the benefits of material re-use.
“With over half of respondents saying they could contribute or receive second-hand materials right now, our research shows that there is huge appetite to increase circular economy practices. Our goal is to increase the profile of re-use in design and construction and to develop an efficient market for second-hand materials in our capital.”
Gary Elliott, Founder and Chief Executive of Elliott Wood, added: “The re-use of second-hand construction materials is the only way forward. The industry has to establish a viable second-hand market which deals with storage, cataloguing and recertification. This is only in its infancy but with the right investment and government support will, we believe, become the norm.”
Colin McColl, Director, Orms commented: “80% of today’s building stock will still exist in 2050 and it is critical that these are included in the industry conversation around re-use and circularity if we are to meet net zero ambitions. Therefore, thoughtful deconstruction and reuse needs consideration as part of a new approach to development, that challenges traditional appraisals and views buildings differently, as material banks.”
Lucy Rees, Sustainability Advisor at UKGBC said: “Reusing building materials is critical to reducing waste and cutting carbon. But to do this successfully, our industry needs to identify and overcome the existing barriers that are blocking the widespread uptake of material reuse in our industry. Grosvenor’s proactive approach to identifying and addressing some of these barriers is both innovative and exciting. We are pleased to see so many UKGBC members already contributing to this project, and highly support and encourage others to join the network and help create a more circular built environment.”
