Coffee To-Go with a difference
What happens to the 18 million tons of coffee grounds that end up in the trash every day in roasteries and cafes around the world?
The TreeShirt Coffee realizes this lost potential: The coffee grounds are dried and processed into viscose, which, together with organic cotton, ensures a pleasantly soft feel combined with functionality. The coffee in the material has odor-neutralizing and antibacterial properties – entirely without additives, thanks solely to the natural properties of the coffee.
This shirt gives you exactly the energy you need so that you too can be active in nature and for nature.
Power of coffee grounds: From cup to textile fiber
The journey to our Coffee Carbon Shirts begins where many people's day begins: with coffee. Instead of ending up in the trash, used coffee grounds are given a second life – as a functional, sustainable textile fiber with special properties. To produce Coffee Carbon, coffee grounds are collected from cafés, roasteries, and instant coffee producers worldwide and processed in several steps:
- Carbonation: First, the coffee grounds are heated and converted into activated carbon.
- Grinding process: This coal is then ground and processed into nanoparticles.
- Fiber blend: The particles are blended with organic cotton.
- Spinning: Together we create the yarn for our Coffee Carbon Shirts.


This creates a functional, environmentally friendly textile fiber with natural advantages:
- Upcycling instead of throwing away: Coffee grounds are reused sensibly and thus become part of a circular production process.
- Climate-friendly: Up to 48% less CO₂ emissions than bamboo charcoal fibers and even 85% less than coconut charcoal
- Heat-regulating: Increases skin temperature by up to 5–10 °C in cold weather – ideal for cold days and outdoor activities
- Breathable & quick-drying: wicks away moisture and keeps you dry
- Odorless & antibacterial: Micropore structure prevents odor formation, negative ions ensure a fresh skin feeling
