Why the industry's green promises are leaving the most critical question unanswered.

The circular economy has been fashion's great green hope. But there's a hole in the loop.
For the past decade, circularity has been the guiding framework for sustainable fashion: keep materials in use, reduce waste, design for longevity. It is a compelling vision — and a necessary one. But there is a fundamental question the circular fashion model has consistently failed to ask: what happens when the materials we keep circulating are toxic?
A loop is only as clean as what's inside it
The standard circular model addresses material flows, but largely ignores chemical content. If a garment contains PFAS, flame retardants, or azo dyes with mutagenic properties, keeping that garment in circulation does not reduce harm — it perpetuates it. A truly circular fashion system must address not just where materials go, but what they are made of.
Why the industry's green promises are leaving the most critical question unanswered.
Recycled polyester is not a neutral choice
Synthetic fibres, including recycled ones, are often marketed as sustainable due to their lower water footprint compared to natural fibres. But producing synthetic fibres is chemical-intensive. The CO2 balance sheet looks cleaner; the toxin balance sheet does not. When we prioritise climate accounting over chemical accountability, we leave the most vulnerable people — workers in dye facilities, communities near production sites, wearers of the garments — outside the equation.
Fragmentation is the industry's trojan horse
Fragmented supply chains mean that each step in production operates according to its own logic, with no shared accountability. No single actor owns the full picture — and so no single actor is responsible for the full harm.
What a genuinely circular future looks like
It begins with material safety as a non-negotiable design principle: asking, before choosing any fibre or treatment, whether it matches its intended use — and whether it can be recycled without releasing toxins.
