We are aevoloop: A fast-scaling deep-tech startup pioneering Next-Gen-Plastics. Contrary to common belief, plastics remain indispensable where no alternative exists, from critical medical devices to protective gear. That’s why we re-engineer polymers from the ground up, merging the advantages of classic plastics — high-performance and versatile — with a new era of sustainability: turning plastic waste into new materials that are fully circular and biodegradable.

Our mission is clear: Plastics are vital for a liveable future, so we develop next-generation materials that enable a truly circular economy. As we achieve new milestones and drive innovation, we continuously expand our team and expertise — giving you the chance to grow your career alongside our impact.

Our work is guided by five values: Pioneering, Conscientious, Disruptive, Transparent and Contributive. These drive us to unite the rigour of responsible research with playful innovation and to act as a trusted catalyst for sustainable material solutions.
