About UpCircle

    Recycling systems are complex. We make them intelligent.

    UpCircle was born from a simple observation: one of the world's oldest industries makes critical material decisions daily - with plenty of gut feeling and experience, but little objective data. We set out to change that.

    As an ETH Zurich spin-off founded by engineers and scientists, one principle is at our core: Decisions are made based on data - not gut feeling. We believe that precise material intelligence not only improves cost efficiency, but makes a measurable contribution to the circular economy.
