Circular-Washing: Hype vs Reality

Greenwashing - making a product or organisation look more environmentally responsible than it is - is old news; the built environment has practised it for decades with vague labels, cherry-picked metrics and green-tinted brochures. Circular-washing is its newest and, in some ways, most effective variant, and construction is unusually fertile ground for it. Three features of the field make the washing easy.

First, circularity is genuinely fuzzy. There is no single agreed definition, no universal certification, no one number that settles whether a building or product is circular. Where a concept is loose, a marketer can pour almost anything into it and few can prove them wrong. 'Circular' has no legal meaning on a brochure, so it costs nothing to claim and almost nothing to defend.

Second, the checks are weak and the claims are far downstream of anyone who can test them. Whether a product is really recyclable, whether a market really exists to take it back, whether a building can really be disassembled and its materials recovered - all of these are only proved decades later, at end of life, long after the sale is made and the marketing has done its work. A recyclability claim made in 2026 will not be falsified until 2066, if ever, so there is little near-term risk in making it. Contrast embodied carbon, which at least has kg CO2e and life-cycle assessment as a shared, if imperfect, yardstick; circularity's yardsticks are newer and more gameable.

Third, circularity is fashionable and morally flattering. It lets a client feel virtuous, a developer differentiate, a product command a premium - and the language (loops, regeneration, nature) is warm and appealing. That demand pulls supply: where buyers want to hear 'circular', sellers will say it. The result is a market where the word races ahead of the substance. None of this means circularity is a fraud - the previous modules are about the real thing - but it means the field is swimming in claims, and that the designer who cannot tell substance from washing will specify badly, mislead clients, and eventually damage their own credibility when the gap shows. Seeing clearly is the precondition for practising honestly.

Circular-washing is not random; it recurs in a handful of recognisable moves. Learn the pattern and you will spot it fast.

1. Recycled content sold as circularity. The commonest move by far. A product boasts '40% recycled content' and is marketed as circular - but recycled content is an input claim about a still-linear product that will be landfilled or downcycled at end of life. As the course has hammered, recycled content is not circularity; it is, at best, a low rung. A carpet tile with recycled backing that is glued down and torn out to landfill in seven years is linear with a green tint.

2. Downcycling called recycling. The brochure says 'recycled', the reality is downcycling - concrete crushed to road sub-base, mixed plastics to bollards, glass to aggregate - a one-way step down to a lesser use from which the material never returns. Calling that 'recycling' (let alone 'circular') is technically defensible and substantively misleading.

3. Vague 'circular' branding with no referent. A building, a product line or a whole company is branded 'circular' with no statement of what is actually cycled, at what rate, to what value. The word floats free of any measurable claim, which is precisely what makes it safe to use and impossible to check.

4. Closed-loop claims that are not closed. 'Closed-loop' implies material returns to the same use again and again. In practice the 'loop' is often a small take-back pilot capturing a few percent of output, with the rest escaping to the ordinary waste stream. An open loop with a photogenic pilot is dressed as a closed one.

5. The single-attribute halo. One genuinely circular feature - a demountable partition, a reused staircase, a take-back scheme for one product - is used to imply the whole building or company is circular. The good feature is real; the extrapolation is the wash.

A sixth, quieter move deserves naming: the future-tense claim - 'designed to be recycled', 'ready for the circular economy', 'when the infrastructure exists'. These describe an intention, not an achievement, and lean on markets and logistics that may never arrive. Intentions matter, but a claim that depends entirely on a future that is not built is a claim about hope, and should be labelled as such.

The way to cut through washing is not cynicism - dismissing every claim - but a set of evidence tests that a genuine claim can pass and a washed one cannot. Carry these questions and apply them to any circular claim you meet.

Which rung of the R-ladder is this, really? Push the claim onto the ladder from Module 1. Is the material kept whole and reused, or repaired, or genuinely recycled to equal value - or is it downcycled, or merely recycled-content in a new linear product? Most washing collapses the moment you ask which rung it actually occupies; the honest answer is usually far lower than the brochure implies.

What share, measured how? A real circular claim comes with a number and a boundary: what fraction of this material is actually recovered and returned to use, measured over what scope, verified by whom? 'Recyclable' is a property; 'X% is actually recovered and reused' is a claim with substance. If no share and no measurement exist, the claim is decorative.

Is there a real route and market - today? Recyclable or reusable in principle means nothing without an actual route: a collector, a processor, a buyer, a logistics chain that exists now, not in a hoped-for future. Ask where, specifically, this material goes at end of life and who pays. If the answer is a pilot, a plan or a someday, the loop is not real yet.

Whole building or one feature? For a building claim, resist the single-attribute halo. One reused staircase does not make a circular building. Ask about the structure, the envelope, the services, the fit-out - are they designed to come apart and documented to be recovered, or is the circular story one photogenic element?

Who verified it, and against what? Independent verification, a recognised standard, a material passport with provenance - or the seller's own brochure? Self-declared circularity with no external check is the weakest evidence there is.

Run a claim through these five questions and the genuine and the washed separate cleanly. The genuine claim answers them with numbers, routes and evidence; the washed claim answers with adjectives. You are not being cynical by asking - you are doing the basic due diligence that circular literacy demands.

The hardest and most important application of the decoder is not to other people's brochures but to your own words. You will be tempted - by clients who want the badge, by the warmth of the language, by genuine partial progress - to call your projects 'circular' when they are, honestly, linear projects with some circular features. Resisting that is a matter of professional integrity, and it is also self-protective: overclaiming is how designers get caught in the greenwash backlash that regulators and the press are increasingly aggressive about.

The discipline is simple to state. Claim the specific, not the sweeping. Do not say 'this is a circular building'; say 'the partitions are demountable and can be reused', 'the steel frame is bolted for disassembly and documented in a material passport', 'we reused the existing foundations'. Specific, verifiable claims are both more honest and more credible than the grand adjective. Name the rung and the share where you can, and say plainly where you are relying on a future market or an unproven route. Distinguish intention from achievement - 'designed for disassembly' (a real design decision you made) is fair; 'will be reused' (a prediction about a future you do not control) should be flagged as an aspiration, not a fact. And defer the binding parts: whether a reused element is safe and certified, whether a claim meets a regulator's substantiation rules, whether a marketing statement is legally defensible - these go to structural engineers, to the governing standards, and to legal and marketing-compliance professionals, not to your own confidence.

There is a deeper point here. The reason circular-washing is corrosive is that it burns the credibility of the real thing - every inflated claim makes clients more cynical about the genuine circular projects that follow. By being scrupulously honest about your own work, naming what is real and what is aspiration, you are not just protecting yourself; you are protecting the credibility of circular design itself. Honesty is not a constraint on circular practice. In a field this full of hype, it is the practice.
