Why It Matters
The SUE showcases how sustainable, fully recyclable materials can be integrated into autonomous public transport, accelerating circular‑economy adoption in mobility solutions.
Key Takeaways
- •Covestro supplies polycarbonate glazing and sensor‑transparent Makrolon AX ST
- •Interior uses recyclable Arfinio monomaterial and durable TPU upholstery
- •SUE minibus will be road‑tested up to 50 km/h later 2026
- •Project funded by German ministry and EU, involving ten partners
- •Design prioritizes circular economy with fully recyclable components
Pulse Analysis
The emergence of autonomous shuttles marks a pivotal shift in urban mobility, but their environmental footprint remains a critical concern. By leveraging Covestro’s high‑performance Makrolon polycarbonate for the panoramic windshield, the SUE minibus achieves both structural integrity and optical clarity while allowing seamless integration of lidar and camera sensors behind a transparent cover. This sensor‑transparent solution reduces the need for additional housing, cutting weight and simplifying the vehicle’s electronic architecture.
Beyond the exterior, Covestro’s Arfinio monomaterial introduces a stone‑like aesthetic that is 100 % recyclable, aligning with the growing demand for circular design in public transport. Paired with TPU‑based seat upholstery, the interior balances durability with sustainability, ensuring components can be reclaimed at end‑of‑life without compromising passenger comfort. Such material choices not only lower lifecycle emissions but also set new standards for recyclability in the automotive sector, where mixed‑material assemblies have traditionally hindered recycling efforts.
The SUE project’s financing by the German Federal Ministry for Economic Affairs and Energy and the European Union underscores policy support for eco‑friendly mobility innovations. Collaboration with ten research and industry partners, including Fraunhofer and Deutsche Bahn, accelerates technology transfer and paves the way for broader deployment across European cities. As regulators tighten emissions targets and cities seek low‑impact transit options, the SUE’s blend of autonomous capability and circular material strategy positions it as a blueprint for the next generation of sustainable public transport solutions.

UE | STUDIOS Unveils the SUE Autonomous Electric Minibus (Developed with Covestro Materials and EU Funding)
UE | STUDIOS has unveiled the SUE (Self‑driving Urban E‑Shuttle), a fully autonomous electric minibus developed for public‑transport applications using materials from Covestro. The vehicle, which features a 381 cm polycarbonate windshield and recyclable monomaterial interior components, will be tested on public roads at speeds of up to 50 km/h later this year.
The project was funded by the German Federal Ministry for Economic Affairs and Energy and the European Union, and developed in collaboration with a consortium of ten partners including the Institute for Automotive Engineering at the Lower Saxony Research Centre for Automotive Technology, TÜV Nord, Fraunhofer Institute EMFT and Deutsche Bahn.

Covestro’s Makrolon AG polycarbonate is used for the panoramic glazing, while sensor‑transparent Makrolon AX ST enables integration of autonomous‑driving sensors behind opaque covers. The interior features the first automotive application of Arfinio, a recyclable monomaterial with a stone‑like appearance, alongside TPU‑based seat upholstery designed for durability in continuous public‑transit operation.
“We considered recycling during the design process and worked with three fully recyclable monomaterials—Arfinio, TPU and polycarbonate—that can be found either in interior or exterior.”
— Jochen Hardt, Head of Global Marketing Mobility, Covestro
“We wanted to develop not just a technologically advanced vehicle, but one optimally aligned with passenger needs in terms of service, information, ergonomics and aesthetics.”
— Alexander Uedelhoven, Founder and Project Manager of SUE, UE | STUDIOS
