Where circular materials meet the people who need them — and where the services that make circularity possible find their audience. Suppliers, brokers, consultants, and specialists: this is your space to share, source, and connect.
The circular economy in construction does not run on good intentions. It runs on materials that exist, services that function, and market players who know how to connect supply with demand across the whole value chain.
This category is the market layer of (re)BUILD — the place where the people who produce, recover, trade, assess, certify, and design with circular materials can find the people who need them. And where the professionals looking to source, specify, or evaluate circular solutions can find the market.
What do we mean by circular materials?
Circular materials are not simply sustainable materials. They are materials that have been designed, recovered, or processed to stay in use — at the highest possible value, for as long as possible.
That includes:
-
Secondary and reclaimed materials — salvaged structural steel, reclaimed timber, recovered bricks and stone, deconstructed flooring, reused façade elements and windows
-
Bio-based materials — hemp, straw, cork, bamboo, timber and wood fibre systems, mycelium — materials that store carbon and return to biological cycles at end of life
-
Materials with high recycled content — recycled concrete aggregates, recycled insulation, secondary aluminium and steel produced from recovered streams
-
Low embodied carbon materials — materials specified and verified for their reduced carbon impact across the full production cycle, including Environmental Product Declarations (EPDs) as the evidence base
-
Components designed for disassembly — building elements engineered to be recovered, reconditioned, and reused in a second or third life cycle
What do we mean by circular services?
The material alone is not enough. The circular construction economy runs on a network of specialised services that make material recovery, reuse, and responsible sourcing possible. Every one of these belongs here:
-
Pre-demolition auditors — assessing reuse and recycling potential before the first wall comes down
-
Selective deconstruction contractors — the hands that recover materials without destroying them
-
Material brokers and traders — connecting surplus with demand across regions and borders
-
Material banks and warehouses — the physical infrastructure of urban mining
-
Urban mining specialists — identifying and unlocking material value in the existing building stock
-
LCA consultants — measuring embodied carbon, attributing impact to reused materials, making environmental claims credible
-
Embodied carbon specialists — professionals who assess, reduce, and verify embodied carbon in construction projects, from material specification through to whole-life carbon reporting
-
EPD verifiers and programme operators — producing and validating the data that underpins circular material specifications
-
Circular design consultants — integrating material circularity from the earliest design stage
-
BIM for circularity specialists — digitising material information for tracking, reuse, and future recovery
-
Material passport providers — creating the digital records that give materials a second life
-
Circular procurement advisors — helping clients and developers write tenders that the market can actually answer
-
Waste management and sorting specialists — closing the loop on construction and demolition waste streams
-
Testing and certification laboratories — validating the performance of reused and recycled materials so they can be specified with confidence
What belongs here
-
Materials available for reuse or sale — with honest description of quality, quantity, location, and condition
-
Sourcing requests — what you need, where you are, what specifications matter
-
Service introductions — who you are, what you do, where you operate, what makes your approach different
-
Technical discussions — performance of secondary materials, contamination challenges, quality assurance for reused components
-
Market observations — pricing trends, availability gaps, logistics barriers, what’s moving and what isn’t
-
Tool and platform reviews — material exchange platforms, tracking software, EPD databases
A note on how this space works best
This is the category where the line between useful contribution and self-promotion is thinnest — and that’s worth naming directly. Suppliers and service providers are not just welcome here, they are essential to what this network becomes. But the posts that build trust and generate real business are not the ones that read like brochures.
Share what you know. Share what you’ve learned about a material stream, a logistics challenge, a quality issue, a market gap. Share the project where your service made the difference — and be honest about the constraints. That kind of content attracts the right clients, builds the right reputation, and makes this category worth reading for everyone.
