## Challenge

Triwool asked for a fully circular, sustainable knit garment with competitive production costs, to reduce the waste and footprint of fast fashion.

## What they built

Infini is a new yarn that combines recycled cotton leftovers with two bio-based polymers. The bioplastic is recyclable and compostable and emits less CO2 than fossil fibres, so Triwool can knit sustainable garments such as T-shirts at competitive cost.

## Impact

The team saw Triwool able to produce fast fashion branded as sustainable while keeping quality and production costs.

## Full project text

A new competitive cost yarn created of bioplastic and leftover cotton targeted towards more sustainable fashion industry.

### Challenge

Design a fully circular and sustainable knit garment product with competitive production costs.

### Solution

Infini comes as a response to the growing ecological problematic created by the fast fashion industry. The major challenge we chose to face was to introduce a new material able to replace fossil materials in the fashion industry as they leave a heavy footprint on earth. Bioplastic is recyclable, compostable, uses less resources to be produced and creates much less CO2 when compared to fossil materials. By combining cotton leftovers and bioplastic a new approach towards a more sustainable industry is paved while staying cost effective.

### Impact

While the fast fashion industry is growing so are the environmental issues but also the awareness of the users. We want cheap, fashionable, long-lasting, and ecological clothes. Triwool is now equipped with the potential to deliver exactly this. They can now produce a new kind of fast fashion and brand it as ecological and sustainable for our environment while maintaining quality and production costs.
