Preserving eco-design and circular economy principles across technology readiness levels.
A decision guide for R&T practitioners working on aircraft cabin components. Navigate circular design criteria, organizational conditions, and sustainability methods across every TRL gate.
01 — Foundations
Two Concepts,
One Challenge
Two related but distinct concepts underpin this tool. Understanding the difference matters for how criteria are framed at gate reviews.
Design
The integration of environmental criteria into the earliest stages of product design, before decisions become costly to reverse. In aviation, environmental impact is dominated by the operational use phase — making weight the primary measurable eco-design criterion, since every kilogram saved directly reduces fuel burn across the aircraft's service life.
MethodEconomy
A resource management model that keeps materials in use for as long as possible through reuse, remanufacturing, and recycling. In aviation cabin development, this shifts the goal from replacing components to recovering their material value — guided by an R-strategy hierarchy from highest-value reuse down to recycling as a last resort.
Strategic Goal02 — Modules
Three Entry
Points
Each module addresses a different dimension of the same challenge: keeping circular intent alive as a project moves from concept to certification.
Navigator
Criteria, framing, and data guidance organized by TRL cluster. Know what is still designable, what evidence is available, and how to defend circular choices at gate review.
Open moduleWorks
Organizational conditions that have protected circular intent in practice. For each example: what condition was in place, why it worked, and how a practitioner can approximate it.
Open module& Tools
A use-this-when overview of methods and tools mapped to TRL stage and barrier type. From value chain mapping to pLCA, find the right instrument for the right moment.
Open module03 — Recommendations
General
Guidance
Cross-cutting advice for keeping circular intent durable through gate reviews, design freezes, and the long quiet middle of an R&T programme.
Engage circular criteria before the design freeze
The earlier circularity is written into the design criteria, the cheaper it is to defend later. After TRL 6, recoverable trade-offs become structurally hard to revisit.
Translate impact into metrics decision-makers already trust
In aviation cabin development, weight is the universal currency. Circular wins land harder when expressed as a fuel-burn delta over service life, not as a stand-alone LCA score.
Pair every method with the gate review it supports
A method without an audience produces a deck no one reads. Sequence pLCA, value-chain mapping, and supplier scorecards to the gate that actually consumes their output.
Document the trade-offs you ruled out, not only the ones you kept
The reasons a circular option was deferred are often the most reusable knowledge across programmes. Capture them inside the gate package, not in side notes that disappear with the team.
