A Circularity Readiness
Model for Infrastructure
Decisions

Circularity is now used in many infrastructure conversations — but it is often invoked long before the conditions for circular action actually exist. This framework shifts the question from "Do we believe in circularity?" to "Are we currently positioned to make circular decisions well?" That shift is more useful, more honest, and more actionable.

The Core Problem

Why "do we believe in circularity?" is the wrong question

A readiness model helps by shifting the question from "Do we believe in circularity?" to "Are we currently positioned to make circular decisions well?" — and that shift matters enormously for infrastructure teams that must make capital decisions under real constraints.

Circularity is now used in many infrastructure conversations. It appears in procurement frameworks, sustainability strategies, programme commitments, and bid documentation. The problem is that it is often invoked long before the conditions for circular action actually exist — creating a familiar pattern of ambitious language, weak implementation pathways, and very little clarity about where an organisation should actually start.

For infrastructure decisions specifically, this matters enormously. Projects are long-lived, capital-intensive, and path-dependent. A poor decision early in design or procurement can lock in waste, inflexibility, or high-carbon choices for decades. Circularity cannot be retrofitted at delivery stage — it must be addressed at conception, which means readiness must be assessed before the design process closes off the options.

This framework measures readiness across six dimensions. The purpose is not a pass–fail verdict. The purpose is to reveal where enabling conditions are strong, where they are weak, and which bottlenecks will most likely block real circular action — so that teams can prioritise intelligently rather than declare ambitiously.

Framework Structure

Six dimensions that determine whether circularity is actionable

Each dimension represents a distinct enabling condition. The pattern of scores — not the average — is where the most diagnostic information sits. A single weak dimension in governance or data may matter more than three credible scores elsewhere. Work through each dimension honestly before moving to scoring.

Readiness Architecture
Six Dimensions — With Diagnostic Focus for Each

The bar length in each row illustrates a sample readiness profile. Teams should replace this with their own scored assessment. Low-scoring dimensions are the priority for intervention — not the highest-scoring ones.

1
Strategic Intent
Does the organisation define circularity clearly enough to guide real decisions, or is the term still being used as a broad aspiration? High readiness here means circular objectives are specific, measurable, and connected to procurement and design criteria — not just stated in a sustainability policy.
Sample score
3.5 / 5 — Credible
2
Design & Specification
Are designers and technical teams able to compare repair, reuse, modularity, substitution, maintenance, and end-of-life implications before procurement closes the option space? Low readiness here means circular options cannot be evaluated at the stage where they would matter most — during concept and detailed design.
Sample score
2.5 / 5 — Emerging
3
Supply Chain & Market Fit
Are there credible suppliers, recovery pathways, reverse logistics, or refurbishment options that make circular choices feasible in the actual operating context? A circular specification that cannot be met by available supply chains is not a circular decision — it is an aspiration with no delivery route.
Sample score
2.0 / 5 — Weak
4
Data & Traceability
Can the organisation identify materials, lifecycles, failure histories, or asset conditions well enough to support circular decision-making? Without data on what materials exist, where they are, what condition they are in, and what their performance history is, reuse and remanufacture decisions cannot be made credibly.
Sample score
1.5 / 5 — Weak
5
Governance & Incentives
Do procurement rules, budgets, contracts, and accountability structures support circular outcomes — or do they quietly reward linear behaviour? Many circular ambitions fail here: the procurement rulebook specifies lowest unit cost, the contract penalises novel approaches, and no one has accountability for whole-lifecycle outcomes.
Sample score
1.3 / 5 — Weak
6
Measurement & Learning
Is there a way to track whether circular interventions are delivering value — or are decisions being made without feedback? Without measurement, teams cannot learn whether their circular choices are working, cannot improve specifications over time, and cannot demonstrate value to stakeholders who are sceptical about higher upfront costs.
Sample score
3.0 / 5 — Credible

Scoring Guidance

How to score each dimension without flattering yourself

Teams should score each dimension using this four-level scale, and justify each score with a concrete recent example — either a success that illustrates the capability or a failure that illustrates the gap. Scoring from aspiration rather than evidence is the most common misuse of readiness frameworks.

The point of the scale is not precision theatre. It is structured conversation. A score difference of one level between team members is a diagnostic signal worth exploring — it usually reveals a gap in shared understanding of what the dimension actually requires.

Scoring Reference
Four-Level Assessment — What Each Level Actually Means
1
Rhetorical
Circularity is claimed but not operationalised. No specific criteria, tools, or processes exist. The language appears in documents but does not shape decisions.
2
Isolated
There are isolated efforts — a pilot project, a willing individual, a one-off specification change — but they depend on champions rather than systems. They have not become repeatable or structural.
3
Credible
Circular choices are becoming operational in selected workflows. The enabling condition exists and is documented, but is not yet consistent across all relevant projects, teams, or procurement processes.
4–5
Embedded
Circularity is embedded well enough to influence design, procurement, operations, and review consistently. It would survive a key person leaving. It can be demonstrated to external stakeholders with evidence.

Application in Practice

A worked example — and what the framework actually produces

The framework works best when applied to one specific infrastructure decision, not to an entire organisation at once. Start narrow: a material substitution choice, an asset-replacement question, a building retrofit package, or a maintenance strategy. Score the six dimensions against that decision context rather than against an ideal future state.

⚙ Worked Example
Infrastructure team considering recycled polymer-enhanced material options in a road surface refurbishment project
A highways team has been asked to consider recycled or polymer-enhanced material options as part of a lifecycle-cost analysis for a refurbishment programme across 40 kilometres of secondary road network. The team applies the framework to this specific procurement decision.

Strategic intent scores 3: leadership wants lower waste and longer asset life, and this is stated in the programme brief. But it is not yet translated into specific technical criteria that procurement staff can use to evaluate bids.

Design and specification scores 2: the technical team can identify recycled-content options, but lacks lifecycle comparison tools that would allow them to evaluate performance, durability, and whole-life cost on equal terms with conventional specification. There is no internal guidance document covering this material class.

Supply chain and market fit scores 1.5: only two regional suppliers have confirmed availability of compliant recycled-content materials at programme volumes, and lead times are 30% longer than the conventional supply chain. There is no recovery pathway for materials at end of life.

Data and traceability scores 1: the programme does not have a systematic record of existing materials in the network by type, age, or condition. Reuse decisions cannot be made without this baseline.

Governance and incentives scores 2: the procurement process uses lowest-price-technically-compliant evaluation, which systematically disadvantages materials with higher upfront cost but lower whole-life cost. No evaluation weighting exists for lifecycle performance.

Measurement and learning scores 2.5: two pilot sections were completed under a previous programme, but no formal monitoring protocol was applied, and outcomes were not systematically recorded.
Framework Output
The diagnosis is not that the team lacks commitment to circularity. It is that data traceability and governance structures are blocking real circular action — and those are the dimensions that should be addressed before the next procurement round, not the strategic intent statement.

Critical Awareness

Three ways this framework is commonly misused

The framework loses its value when teams use it to confirm existing assumptions rather than challenge them. Three misuses account for most of the cases where readiness assessments produce useless or misleading results.

Turning it into a branding device
If teams use the maturity language only to signal innovation status — without honest scoring — the framework produces a flattering narrative rather than a diagnostic. The score should be justifiable with specific recent examples, not with aspirational policy language.
Ignoring context specificity
Circularity looks different in settings with weak recovery infrastructure, unstable supply chains, or limited traceability. The framework should help adapt expectations to context — not erase it. A score of 3 in a well-resourced European context may represent stronger real conditions than a score of 3 in a resource-constrained setting with different market structures.
Treating all dimensions as equally urgent
In practice, a low score in governance or data traceability may be far more constraining than two moderate scores elsewhere. The framework should produce a prioritised intervention list — starting with the dimension whose weakness most directly blocks circular action in the current decision context.

Decision Gate

Before committing to a circular approach — six questions

These questions function as a minimum gate for circular infrastructure decisions. If any question cannot be answered clearly and specifically — with reference to real conditions rather than programme aspirations — the readiness is not yet sufficient for the circular approach to be described as a credible decision rather than a stated preference.

Readiness Gate
Six questions before any circular infrastructure commitment
What value are we retaining — and through what specific mechanism, at which lifecycle stage?
Are there credible supply chain options that can meet circular specifications at required volumes and timescales?
Does our data on existing materials and assets support reuse or remanufacturing decisions — or are we working from assumptions?
Does our procurement process evaluate lifecycle value — or does it systematically select against circular options through lowest-price criteria?
Are there standards or testing pathways for secondary or recycled materials in this specific application class?
How will we know whether it worked — what monitoring will we apply and who is accountable for reporting the outcome?
