The Challenge

The global textile market produces 1.2 billion tons of CO2 equivalent per year and uses dyes that are responsible for 20% of global wastewater. The industry also depends on petroleum based synthetic fibers that account for 35% of global microplastic pollution.

Innovation Details

Werewool is creating a revolutionary fiber development platform to create biodegradable fibers with tailored aesthetic and performance properties. Inspired by nature, and utilizing the tools of biotechnology, Werewool is developing a platform to design fibers at the DNA level for sustainable textiles with inherent properties such as color, moisture management, and stretch, that meet the demands of today’s consumers. The team identifies structures found in nature, such as the red fluorescent protein found in some species of Discosoma, a coral relative. They then grow fibers that are reliant on these proteins, creating textiles without the need for toxic dyes, finishes, and petroleum based synthetics.

Watch how Werewool uses proteins found in nature to produce natural color.

Biological Model

Nature’s organisms have evolved structural proteins to support their ability to survive. For example, the Discosoma Coral depends on the structure of RFP (red fluorescent protein) as a source of colorant to support a symbiotic relationship with an algae to survive. Werewool is emulating proteins found in nature to create natural color, and apply it to create textiles without the use of dyes or s.
