Construction Product Ontology

A Circular Construction Product Ontology (CCPO) that standardises construction product data to support digital product passports and automated end-of-life decisions (reuse, repair, refurbishment), improving interoperability and material reuse in the built environment.

Circularity Relevance

Core

The ontology is explicitly designed to support end-of-life decision-making, Digital Product Passports and material reuse in construction - a core circular economy function. Source: Adu‑Duodu et al., 2025

Circular Role

SupportEnabler

Provides standardised data and vocabulary (ontology) that other platforms (marketplaces, DPP systems, BIM tools) can use - functions as a SupportEnabler.

Circular Type

Standardisation

• Ontologies

CCPO is an ontology intended as a standardised vocabulary/data model for construction products and end-of-life decision-making (ontology artefact). Source: Adu‑Duodu et al., 2025 - institutional copy: Cardiff ORCA.

R Strategy

R3 - Reuse, R4 - Repair, R5 - Refurbish

Primary evidence addresses reuse (R3). Paper defines reuse categories (strong/weak/none) and repair/refurbishment actions for weak reuse - supporting R4 and R5. Source: Adu‑Duodu et al., 2025

Circular Business Model

Unknown

CCPO is a technical/standards artefact (ontology); it is not itself a commercial business model. Specific business models enabled by the ontology (marketplaces, DPP services) are out of scope for the ontology paper.

Organisational Type

NonProfit

Developed by academic researchers at universities (Newcastle, Cardiff) - classified as NonProfit (academic research output).

Sector

Construction & Built Environment

Paper and implementation focus explicitly on construction products, end-of-life and reuse; sector clearly 'Construction & Built Environment'. Source: Adu‑Duodu et al., 2025

Geographical Reach

International

• United Kingdom

Developed by UK universities but published on arXiv and intended for general/interoperable use across jurisdictions; evidence of international accessibility via preprint and institutional repository.

Hardware Component

None

CCPO is a data ontology/standard; it does not require specialised physical hardware to operate.

Tech Map Relevance

CCPO (Circular Construction Product Ontology) is a data/ontology standard intended to enable Digital Product Passports and end-of-life decision-making for construction materials (see arXiv and Cardiff ORCA). This makes it relevant as a digital enabler for circular construction markets and DPP interoperability. Source: Adu‑Duodu et al., 2025 Source: Cardiff ORCA repository
