Müll
An interactive app that helps users sort, recycle, and upcycle waste correctly — through clear guidance, gamified learning, and location-based recycling support.
Problem statement
People new to Germany struggle with recycling due to unclear guidelines, language barriers, and regional rules.
Waste recycling in Germany
Persona
Vision
Empowering individuals and communities in Germany to make sustainable waste management effortless, informed, and collaborative — through a smart, location-aware mobile solution.
Market research
Where are we trying to bridge the gap?
- Language barrier — recycling rules are often only in German, hard to follow for newcomers.
- Location — disposal rules vary city to city, with no easy way to know what applies where you live.
- Create awareness — most people don't realize the downstream impact of poor sorting.
- One-stop solution — guidance, location, and learning currently live across too many places.
Process
- Research — identifying problems with recycling and waste management in Germany.
- Ideation — sketching, creating moodboards, and low-fidelity wireframes.
- UI design — designing the visual style, design system, color scheme, and fonts.
- Prototype — building the high-fidelity prototype based on the concept.

Future potential
- Personalized eco insights — track users' recycling habits over time and show impact data (e.g., CO₂ saved, waste diverted) with weekly / monthly reports.
- Gamified eco challenges — local or global challenges (e.g., "Sort 20 items correctly this week") with leaderboards and rewards.
- Upcycling tutorials — short, interactive tutorials that help people repurpose trash, like making decorative items from cardboard and paper waste.
