The Problem

Textile dyeing consumes 92 trillion litres of water annually and pollutes rivers with heavy metals and azo dyes, particularly in developing economies. Conventional synthetic dyes rely on petroleum feedstocks and toxic fixatives. Sustainable, non-polluting dyeing methods are urgently needed.

Coral fluorescent proteins inspire biodegradable, vibrant coloured fibres without synthetic dyes, eliminating textile industry's water pollution.

Reef-building corals produce fluorescent proteins (GFP, RFP) to absorb excess sunlight energy and re-emit it safely, protecting symbiotic zooxanthellae from photodamage. These proteins exhibit extraordinary colour saturation, photostability, and biological efficiency—traits the synthetic dye industry has attempted to replicate for centuries using energy-intensive chemical synthesis and toxic fixatives. Textile dyeing is the second-largest water polluter globally, accounting for 92 trillion litres of wastewater annually, contaminating rivers and groundwater with heavy metals and azo dyes. Werewool approached this by extracting and cultivating coral-derived fluorescent proteins, then genetically engineering bacteria to produce them at scale. Rather than chemically dyeing fibres, the company ferments genetically modified organisms that secrete fluorescent proteins directly onto wool fibres during cultivation. The result is Werewool—textiles with vibrant, stable colours (reds, greens, cyans) that are fully biodegradable, non-toxic, and require no water-intensive rinsing or chemical fixation. Each fibre is literally a biological composite, embedding living protein pigments. Field trials demonstrate colour fastness exceeding conventional dyes whilst eliminating wastewater entirely from the dyeing process.

How Scleractinian coral fluorescent proteins translates into Werewool - Coral Fluorescent Proteins in Biodegradable Dyes

Term

Applied to Werewool - Coral Fluorescent Proteins in Biodegradable Dyes

Function

Corals must protect delicate photosynthetic partners from excess light whilst creating vibrant colours for mate attraction and species recognition. They solve this by synthesising fluorescent proteins that absorb dangerous wavelengths and re-emit them safely.

Mechanism

Coral fluorescent proteins (GFP variants) contain a chromophoric tripeptide (Ser-Tyr-Gly) that absorbs blue-green light and emits red or green fluorescence. This protein is synthesised in situ, requires no external fixatives, and remains photostable for the coral's lifetime—decades or centuries.

Design Principle

Replace chemical dye synthesis with biological production of colour-active compounds. Integrate pigment production directly into fibre cultivation rather than as a post-processing step. Design for full biodegradability of both fibre and pigment, enabling circular textile systems.

Resulting Design

Werewool textiles achieve vibrant, stable colours through embedded biological pigments that require no chemical dyeing, water rinsing, or toxic fixatives. This eliminates wastewater entirely from the dyeing process whilst producing fully compostable, non-polluting textiles.
