The construction sector is entering a strategic inflection point. Climate adaptation, housing demand, sustainability regulation, material scarcity, energy transition, mobility decarbonisation, and spatial constraints are converging. This combination makes one thing clear: linear construction is no longer viable. The Interreg ASSET project examined how a circular built environment can be spatially, logistically, and economically implemented in Europe, specifically in the EuroDelta megaregion (NL–BE–NRW, ~47 million inhabitants and ~13% of EU GDP), with highly relevant implications for the construction value chain.
The urgency is now spatial and economic
Construction is one of Europe’s most resource-intensive sectors, responsible for ~50% of extracted materials, ~35% of waste generation, and 5–12% of material-related GHG emissions. Meanwhile, the building demand remains strong: the Netherlands is projected to add >2.6 million homes by 2050, NRW ~1.4 million, and Belgium ~1.5–2 million. This demand competes with energy infrastructure, industrial transition, nature restoration, mobility, water protection, and climate adaptation.
The ASSET report, therefore, identifies space as the scarcest production factor of the circular transition. Circularity requires not only circular products and design, but also circular spatial systems for storage, processing, dismantling, biobased cultivation, urban mining, certification, and low-impact logistics. The Netherlands Environmental Assessment Agency estimates that circular activities could require up to 40% more space on existing industrial sites.
Three value chains as transition levers
ASSET tested three value chains at scale:
(1) Biobased construction materials (timber, fibres, algae)
The Go Biobased map shows that new rural-urban linkages are required for cultivation, first processing, and multimodal logistics. Waterways and inland ports become crucial interfaces to cities. Substitution of concrete and steel with biobased materials offers climate, health, and regional economic benefits.
(2) Urban mining (concrete, steel, technical installations)
The Go Secondary map shows that demolition and renovation cycles generate significant flows of reusable materials. Scaling urban mining requires hubs for dismantling, certification, quality assurance, storage, and digital traceability, functions that are barely present in today’s spatial planning.
(3) Chemical & steel clusters
Circular chemistry and polymer recycling concentrate around ports and heavy industrial corridors. However, these locations increasingly compete for housing, energy, and logistics, creating governance challenges that exceed the scope of a single municipal jurisdiction.
Logistics becomes the strategic bottleneck
The report introduces four circular spatial typologies: harvesting spaces, logistics spaces, production/processing spaces, and utilisation spaces — all supported by low-impact logistics. In linear construction, these functions are fragmented at best; in circular construction, they require orchestrated spatial planning.
A key insight: logistics determines cost, feasibility, and environmental performance. Water and rail are structurally more attractive for bulk flows; urban zero-emission logistics policies accelerate consolidation and specialised hubs.
A new role distribution across the construction value chain
Circular construction shifts value creation toward:
- modular & demountable design
- maintenance & lifetime extension
- reverse logistics & material harvesting
- material certification & marketplaces
- digital building passports
- leasing & service-based models
- residual value modelling
This creates a post-construction “afterlife” market. Developers gain residual value models; construction firms gain new service models; municipalities gain spatial orchestrator roles.
Governance defines the speed of transition
The biggest bottlenecks are non-technical: fragmented standards, insufficient market volume, lack of certification, slow permitting, limited spatial integration, and poor data interoperability. ASSET therefore proposes a six-step spatial strategy that focuses on ambition alignment, value chain prioritisation, logistics hubs, and integrated policy.

The core conclusion for construction managers: circularity is no longer a material innovation problem but a spatial, logistical, and institutional transition. Competitive advantage will favour actors who master chain coordination, modularity, reverse logistics, digital traceability, and regional collaboration.
2. Recommendations for the construction industry
A. Strategic (Board/CEO level)
- Shift to value chain orchestration, not just project execution
The winning firms will act as integrators, controlling flows, data, logistics and certification. - Develop residual value models for buildings
Treat buildings as material banks with future asset value instead of end-of-life liabilities. - Position in at least one circular value chain
Choose a role in biobased, urban mining, or circular chemistry — not all three.
B. Operational (COO/Procurement/Engineering)
- Invest in demountable & modular standards
Standardisation reduces reverse logistics cost and increases reuse rates. - Build partnerships around reverse logistics hubs
Work with ports, inland terminals, and industrial estates — not just demolition firms. - Require digital traceability (material passports)
Traceability becomes as important asthe strength class or CE-marking.
C. Market & Business Model Innovation
- Develop service-based models (build-as-a-service, lease, upgrade)
These create recurring revenue streams and lower lifecycle emissions. - Create internal marketplaces for reclaimed materials
Start with non-structural flows (installations, façades, interior elements) where certification is easier.
D. Policy & Governance Engagement
- Engage with municipalities on spatial needs
Circular construction cannot scale without zoning for storage, processing, hubs, and training. - Join or form regional circular coalitions
No single actor — developer, contractor, or municipality — can build the circular system alone.
