Felix Puller : Qmilk



Qmilk uses surplus milk unfit for human consumption to produce a new casein-based fiber as a bio-textile replacement for cotton.


In Germany alone, 1.9 million tons of waste milk must be disposed of every year, milk that is unusable in the food sector but retains valuable renewable ingredients. At the same time, 30% of the world’s pesticide usage is in cotton production, damaging the environment and depleting huge quantities of water in the process.


Qmilk is manufacturing a new antimicrobial, flame-resistant and non-allergenic fiber based on the milk protein casein. The production of 1 kilo of Qmilk fiber requires just 5 minutes and 2 liters of water while recycling the casein. This fiber is 100% biodegradable and created from only natural and renewable resources. There is zero waste in the process, from production to end of life composting. Clothing and home textiles are essentially being made from milk.

“Qmilk takes a highly innovative approach to repurposing a waste stream that is seen in every country in the world.” – Anke Domaske, Founder and CEO of Qmilk

Stage of Innovation: Prototype


This innovation will change the textile, agriculture and dairy industries and have a positive impact on consumers. The Qmilk team is looking for partners to help take their innovation to scale, including the clothing and home textile, automotive, paper and medical industries.

“When we first began 2 years ago we didn’t even have a lab – we started in a kitchen with just €200 worth of equipment. Now we can’t keep up with the demand.” – Anke Domaske, Founder and CEO of Qmilk
