Circular Economy — The Futures Collective

The Double Hexagon at a glance. This walks one focal question through the foresight side of the Double Hexagon — Align, Scan, lightweight Sense-make, then Backcasting as the main strategic move. We don't run scenarios. We name the end-state and work backwards, asking what had to be true at each step for the next to be possible.

How to read this example

Each section is signposted:

─── STEP N of 6 ─── HEXAGON 1 · <PHASE> · <TOOL> ───

Read straight through, or skip to one tool. Each step ends with Try it yourself.

Framing note. We keep this deliberately at the system / global scale. There's a huge body of useful work on city-level circularity, sector-specific EPR design, and household behaviour change — none of which we touch. The pedagogical point of this example is to practice backcasting on a problem where the end-state is clear-ish but the path is genuinely murky. Circular economy is the canonical case.

Confidence note. Current-state signals (Circularity Gap, EU regulation, sector emissions) are referenced. The 2050 end-state and every step backward from it are constructed. Backcasting is a structured argument, not a forecast.

Why this topic, why this tool

A linear-to-circular shift is one of the more agreed-upon long-horizon goals in contemporary policy — at least in declarations. The Circularity Gap Report estimates global material circularity at about 7-8% currently. (1) The EU's Circular Economy Action Plan, the EU Packaging and Packaging Waste Regulation (PPWR, effective 2025), the Right to Repair Directive (entered force July 2024), and Extended Producer Responsibility schemes across dozens of jurisdictions all point in the same general direction. (2, 3)

But the path — what gets restructured first, what gets restructured second, what's load-bearing vs theatre — is contested. "Recycle more" doesn't get to circularity. Nor does any single policy lever.

Backcasting is built for this. The founding intuition (Robinson 1990, building on Lovins's earlier work) was that for normative questions — where the end is named — prediction is the wrong tool. Backcasting names a desirable future and asks: what would have to be true, working backward, for that future to be reached? (4) The discipline isn't prediction; it's necessary conditions.

The pedagogical move here is to practise the backcasting form — not to assert that 2050 will be circular.

Focal question: If global material throughput is structurally circular by 2050 — meaning, say, 70%+ circularity rate, with primary virgin-material extraction down by ~50% versus 2024 — what had to happen, in what order, between now and then?

A note on framing. We're using a quantified end-state on purpose. "Circular by 2050" is too soft; you can't backcast from it. "70% circularity rate, primary extraction down ~50%" is specific enough that we can ask what each five-year window had to deliver. Whether those numbers are right is a separate question. They're operative.

STEP 1 of 6 · HEXAGON 1 · FRAME · The end-state

The backcasting end-state needs three things:

A date. 2050 — far enough that today's plumbing isn't binding; close enough that 2026 decisions matter.
Quantified targets. Not aspirational; not exhaustive; just enough to test against.
Architectural commitments. What kind of economy is this? Without these, the backcast collapses into "everyone recycles more."

End-state (constructed, illustrative):

Material circularity rate: 70%+ of materials in active use globally are circulated (reused, refurbished, remanufactured, recycled into equivalent applications). Today: ~7–8%. (1)
Primary virgin-material extraction: halved relative to 2024 absolute volumes, even with population and middle-income-class growth.
Five highest-emission material sectors restructured: cement, steel, aluminium, plastics, and the food system. Ellen MacArthur Foundation modelling suggests ~9.3 GtCO₂e/yr abatable in these five alone under circular strategies. (5)
Repair, refurbishment, and remanufacturing are first-order economic categories with their own statistics, financial instruments, and labour categories — not residual.
Producer responsibility is the default; the physical product is not the unit of sale for most durable-goods categories. Services, leases, and lifecycle-managed access are common.
Waste-to-incineration and waste-to-landfill are minority disposal categories, not majority.

Architectural commitments:

This is not de-growth. (We're not assuming reduction of human flourishing.)
This is also not "decoupling 2.0" — we're not assuming a magical efficiency wave.
This is infrastructure shift: how materials physically move; how products are designed; how producers are held accountable.

KANCILS to surface the obvious

Keep. Sector-specific EPR schemes that work; cement and steel chemistry research; Right-to-Repair statutory base; the consumer-electronics labelling regimes.
Away with. Recycling-as-virtue rhetoric that displaces upstream design responsibility. Headline "X% recycling rate" metrics that count export-as-recycled.
Never. A future where circularity is purchased by wealthier blocs through waste-export to lower-income regions (a continuation of the 1990s–2010s plastic-export pattern). A future where the human cost of informal recycling is invisible.
Challenging. Cement and steel chemistry is hard. Plastic types proliferate faster than recycling capacity adapts. Trade regimes were not built for circular flows.
Important. Whether the 2050 end-state is reached equitably — not just whether it's reached — is the structuring distinction.
Learn. That market signals alone don't price externalities at the speed circular transitions need.
Strengthen. Material flow analysis (MFA) capacity in lower-income economies; international standards bodies' (ISO, CEN) responsiveness to circular product definitions.

Try it yourself

Define your end-state for backcasting:
1. A date
2. 3–5 quantified targets (not exhaustive; enough to test against)
3. 3–5 architectural commitments — what *kind* of system is this?
4. Run KANCILS to surface what is being assumed / refused / kept

Test your end-state: can a reasonable person read it and disagree?
If not, you've made it too soft. Sharpen.

STEP 2 of 6 · HEXAGON 1 · SCAN · Where we actually are in 2026

We sample the current state — not exhaustively, but enough to ground each backcasting step.

Material flows

Global material consumption grew >3× over the last 50 years; growing ~2.3%/yr. (1)
Circularity Gap Report: ~7–8% global circularity rate, declining in some recent measurements as material extraction outpaces circulation.
A 70%-reduction target for material consumption is consistent with meeting current needs while staying within Doughnut-style boundaries — but the political economy of getting there is mostly unbuilt.

Regulation

EU PPWR effective Feb 2025; reuse and recycled-content targets binding through 2030. (2)
EU Right to Repair Directive entered force July 2024. (3)
US: state-level R2R legislation (NY, MN, CA, others); federal action limited. EPR schemes proliferating at state level for packaging.
Asia-Pacific: Japan's longstanding Home Appliance Recycling Law; Korea's EPR system; China's Circular Economy Promotion Law (2009, updated). Indonesia's plastic-bag and EPR initiatives advancing.

Industrial / Sectoral

Cement: alternative-binder R&D (calcined-clay limestone cements, geopolymers) maturing; deployment lags. Sector contributes ~7% of global CO₂.
Steel: hydrogen-DRI pilots (HYBRIT, H2 Green Steel, ArcelorMittal) operational; commercial scale arriving 2027–2030.
Plastics: chemical recycling pilots; mass-balance accounting controversies; bioplastics still single-digit % of polymer market.
Textiles: EU strategy released; per-garment EPR fees being modelled; resale and rental markets growing but small.
Food: regulatory recognition of food-system circularity (the EU Soil Monitoring Law, Farm to Fork) advancing; agricultural inputs not yet structurally circular.

Finance

Green and circular taxonomies (EU Taxonomy, ASEAN Taxonomy) maturing.
Producer responsibility cost internalisation is uneven; the price signal of waste is far below its real externalities in most jurisdictions.
Insurance and asset-management firms beginning to price stranded-asset risk for linear-business-model companies.

Labour and Social

Repair, refurbishment, and reverse-logistics are growing employment categories in some economies; informal-sector recyclers globally remain ~15-20 million workers with limited protection.
Right to Repair has unevenly distributed labour implications — independent repair sectors regaining viability in some markets.

Gap note. Our scan is heavy on EU and US signals, light on China's actual industrial restructuring (which dominates many of the relevant material flows), and thinner on lower-income-country waste-pickers and informal recyclers (whose role in any global circularity transition is enormous).

Try it yourself

Sample the current state of your topic across regulation, material /
physical flows, finance, labour, and culture. Mark where each signal
sits relative to your end-state — is this signal close to where 2050
needs to be, or far?
Flag where the gap is so large that the backcast will need to invent
a structural change, not just an acceleration.

STEP 3 of 6 · HEXAGON 1 · SENSE-MAKE · Identify load-bearing transitions

Backcasting is more disciplined when you've named, in advance, which transitions are structurally hard versus merely operationally hard. Operational: more EPR schemes, more recycled-content targets, more deposit-return systems. Structural: changes to ownership, accounting, trade flow, and labour categories.

We sketch the structural transitions the end-state requires:

Ownership / product-as-service shift. For durable goods, manufacturers retain title or lifecycle responsibility. This is a legal-economic shift, not just a marketing one.
Material-passport infrastructure. A globally interoperable system for tracking material composition and provenance through products' lives. (EU Digital Product Passport is an early move.)
Trade regimes for circular flows. Current Basel Convention rules and WTO frameworks were built for waste-as-bad and new-goods-as-good. Circular flows of pre-used components don't fit cleanly.
Cement and steel chemistry breakthroughs deployed at scale. Not just R&D — actual gigatonnes/yr at commercial cost.
Plastic chemistry simplification. Reduction in polymer-type proliferation; harmonised additive lists; mass-balance accounting reformed.
Labour reclassification. Repair, refurbishment, reverse-logistics, and informal-sector recyclers move from invisible / marginal categories to recognised, regulated, paid work.
Pricing externalities (carbon, materials, pollution). A genuine, global-floor price on virgin-material extraction and on waste externalities.

Each transition has different drivers and timelines. None happens by 2050 without commitments made well before.

Try it yourself

Sketch the *load-bearing* transitions your end-state requires.
Distinguish:
- Operational transitions (more of what's already happening, scaled)
- Structural transitions (changes to ownership, accounting, trade,
  classification)
Aim for 5–8 structural transitions. These will be the anchors of your
backcast.

STEP 4 of 6 · HEXAGON 1 · STRATEGY · Backcasting from 2050

Name a quantified 2050 end-state, then reverse-engineer what each step required.

We walk the path backwards in 5-year windows. The discipline at each window is: if the next window is to be possible, what had to be true in this one?

2050 — End state

70%+ material circularity rate
Virgin extraction halved vs 2024
Five high-emission sectors (cement, steel, Al, plastics, food) restructured
Producer-retained-title or lifecycle-responsibility is default for durable goods
Repair / refurbishment / remanufacturing as first-order economic categories

2045 — Pre-end-state

Material passports for all imported durable goods entering G20 markets. Passports interoperable between EU, US, China, India.
Cement: ~40% of new cement is alternative-binder (calcined-clay limestone, geopolymer, magnesium-based). Commercial cost parity reached around 2042.
Steel: hydrogen-DRI provides ~50% of primary steel. Scrap-based EAF accounts for another 40%.
Plastics: regulated polymer-type reduction. Major durable-goods sectors limited to ~5 base polymers.
Carbon prices in G20 markets at $200+/tCO₂e equivalent. Material-extraction levy in place in ~30 jurisdictions.
Reverse-logistics infrastructure (collection, sorting, dispatch back to manufacturers) at scale.

2040 — Inflection

EU Digital Product Passport scope extended from textiles / electronics / batteries to broad durable-goods categories.
Hydrogen-steel cost-parity with conventional achieved by 2038 in EU and North America; Asian deployment lagging by ~5 years.
WTO frameworks formally amended (or worked around via plurilateral agreements) to permit cross-border circular flows without classification as waste.
Labour: repair / refurbishment / remanufacturing recognised occupations with sectoral wage floors in EU and 4–5 other jurisdictions.

2035 — Crossroads

First wave of EPR-shift to full lifecycle cost (not partial recycling cost) in EU. Producers begin to internalise the full disposal cost as part of pricing.
Producer-retained-title arrangements (cars-as-service, appliances-as-service) at meaningful share (~10–15%) in EU consumer durables.
Material passports in place for textiles, batteries, electronics, vehicles — mandatory.
Carbon prices in EU ETS at $150+/tCO₂e; California / WCI / Korea / China ETS converging.
First wave of informal recycler integration programmes — formalising waste pickers in India, Brazil, Indonesia, Egypt — connected to EPR financing.
Steel: first 5+ GW/yr capacity of hydrogen-DRI commercially operating.

2030 — Foundations

Right to Repair becomes default across G7 with implementing regulations; cross-border parts standards harmonising.
EU PPWR delivers measurable packaging waste reduction; precedent for sector-specific volume caps.
Cement and steel alternative-tech: hydrogen-DRI commercial demonstration; alternative binders >10% of new production.
ASEAN, AU, Mercosur ratify and implement core EPR principles.
Material-extraction levies introduced in at least 5 jurisdictions.
Plastics treaty (under UNEP negotiation since 2022) ratified and in force.

2026 — Today, looking forward

What 2030 demands of us now:
- Plastics treaty negotiations land; the proceduralism risk is significant.
- Cement and steel decarbonisation pilots get committed buyers (green-premium offtake agreements).
- Material passport standards committee work accelerates beyond EU.
- Right to Repair scope expansion in US states and across non-EU OECD.
- First serious informal-recycler integration pilots receive sustained donor + government funding.
- National-level material flow accounting becomes a statistical priority.

Try it yourself

Backcast from your end-state in ~5-year windows.
For each window, name:
- What is true (capacity, prices, regulation, technology, labour)
- What had to happen between this window and the previous (i.e., the
  next-younger window)
- What 2026 commitment this implies

Stop where 2026 implications get clear. The point isn't to write a
plan — it's to surface what 2026 commitments are *load-bearing* vs
*theatre*.

STEP 5 of 6 · HEXAGON 1 · STRATEGY · Wind-tunnel two moves

A backcast can mislead if it makes the path look smoother than it is. We wind-tunnel two candidate 2026 commitments by asking which 2050 they each deliver, and where each breaks.

Move A — Push hard on Extended Producer Responsibility expansion globally

Holds up in: most paths. EPR is one of the more robust structural levers.
Risks: EPR schemes that focus on collection costs without changing product design (i.e., paying for waste rather than preventing it) generate the appearance of progress without structural change. Many existing EPR schemes are in this trap.
2050 image it delivers: a recycling-heavy 2050 with modest structural change. Not the end-state we named.

Move B — Invest in producer-retained-title (product-as-service) economic infrastructure

Includes: lease-based accounting standards, regulatory clarity on returned-goods classification, financing of reverse-logistics infrastructure, consumer law adjustments.
Holds up in: paths where ownership shifts are accepted. Politically harder than EPR.
Risks: a "rental dystopia" where consumers lose ownership without gaining circularity — large companies extract rents without redesigning products.
2050 image it delivers: a structurally circular durable-goods economy if paired with strong consumer-protection and labour frameworks. Otherwise, a worse version of today.

What survives across both moves?

Material passport infrastructure
Trade-rule reform
Labour reclassification
Material-extraction levies

These are the robust 2026 priorities — not the most exciting, often the least funded.

Try it yourself

Pick 2 candidate 2026 moves. For each:
- Which paths does it hold up in?
- Where does it deliver the *appearance* of progress without
  structural change?
- What 2050 image does it actually produce if pursued alone?
List the moves that survive across both candidates — these are the
non-glamorous infrastructure investments.

STEP 6 of 6 · HEXAGON 1 · REFLECT · Honest read on the backcast

Reflective questions after a backcast:

1. Where did you fudge? Where did a single bullet ("commercial cost parity reached around 2042") quietly do an enormous amount of work? Cement and steel chemistry are the big ones in this backcast. The path is plausible only if the cost-parity bullet is delivered.

2. What did you smuggle in as inevitable? We treated material passports as obviously achievable. They are technically simple and politically dense. (Who owns the data? Who is excluded from the standard? Who pays for the audit infrastructure?) A real exercise would slow down here.

3. What's the path you didn't draw? We didn't draw the path where the global political economy doesn't converge on circular goals. (The de-globalisation backcast.) Drawing it would be a useful counter-exercise.

4. What's the 2026 action that the backcast actually implies? For a sectoral organisation: pick one of the five high-emission sectors and look at what's load-bearing in 2030. Work back from there.

For an advocacy organisation: shift attention from waste-management EPR debates to product-as-service and trade-rule reform.

For a researcher: study informal-recycler integration cases (Pune SWaCH cooperative, Bogota recicladores, Cairo Zabbaleen) as paradigms for the global labour reclassification.

For an investor / financier: stranded-asset risk in linear-business-model companies — by 2030 not 2040.

5. What does the backcast refuse to do?

It refuses to forecast. It is a structured argument about necessary conditions.
It refuses to allocate blame.
It refuses to substitute for sectoral expertise — each of the structural transitions has its own discipline of practice.

The backcast's value is that the conversation in 2026 changes when the question is not "what should we do about circular economy?" but "given that we want X by 2050, what had to be true by 2030?" The second question is much more answerable, and the answer surfaces commitments that today's policy debate doesn't.

Try it yourself

Reflect on your backcast in 60 words or fewer per question:
1. Where did I fudge?
2. What did I smuggle in as inevitable?
3. What path did I refuse to draw?
4. What 2026 action does the backcast actually imply?
5. What does the backcast refuse to do?

What this example does and doesn't claim

Documented (with citations):

Circularity Gap Report: ~7–8% global circularity figure (1).
EU Packaging and Packaging Waste Regulation (PPWR) effective 11 February 2025 (2).
EU Right to Repair Directive entered force July 2024 (3).
Ellen MacArthur Foundation modelling: ~9.3 GtCO₂e/yr abatable in five sectors under circular strategies (5).
Backcasting as a method (Robinson 1990, Lovins earlier) (4).

Constructed:

The 2050 end-state (70% circularity, halved virgin extraction) is operative, not predicted. It's set high enough to make the backcasting tractable.
All backcasting windows (2026, 2030, 2035, 2040, 2045, 2050) are speculative chains of necessary conditions. Specific numbers (e.g., "hydrogen-DRI cost parity around 2038", "carbon price $200+/tCO₂e by 2045", "EPR expansion under specific timelines") are illustrative anchors only.

Out of scope:

City-level circular economy programmes (well-covered elsewhere).
Sector-specific deep dives. The example walks across cement, steel, plastics, textiles, food — but a real cement-circularity exercise would be a separate, much deeper backcast.
The de-globalisation counter-scenario. Worth running.
Consumer behaviour change. Treated as endogenous to structural shifts here.
