How we built a simple, user-friendly tool to turn composting from intention into action.

Timeline: 6 weeks
Deliverable: Physical prototype + research-backed insights
Challenge
72% of Americans don’t compost, yet 67% say they would if it were easier. We set out to design a solution that helps users follow through on good intentions by reducing friction in daily routines.
My Contribution
- Led empathy research and co-developed interview script
- Synthesized findings into journey maps and user needs
- Co-designed and tested final prototype
- Led visual storytelling for final presentation
User Interviews & Personas
We interviewed individuals with different living situations and composting experience to understand the behavioral barriers. While some users composted regularly, others wanted to but hadn’t started. Their feedback helped us identify common patterns, which we translated into key personas that shaped our design.
Lisa
Age: 50
Lives: Suburban home
Composts through a pickup service but often second-guesses items. Wants composting to be second-nature, not extra work.
Cole
Age: 21
Lives: College apartment
Wants to compost but doesn’t know how. Hesitant because of shared space and lack of a system that fits easily into daily life.
Maya
Age: 28
Lives: City apartment
Environmentally aware but busy. Wants composting to be intuitive and compact without extra research or setup.
Key Insight
Ideation
After analyzing our research insights, we held a group brainstorming session to generate a wide range of solutions. We explored over 25 ideas, from smart trash cans and composting starter kits to educational workshops and visual flyers. The most promising concept was a modular bin that could easily integrate into existing systems without requiring major behavior change.
We asked ourselves: “What intervention would feel helpful in the moment someone is about to toss something?” That guiding question led us to prototype a solution that felt both simple and scalable.
Solution
We designed a clip-on compost bin with visual signage that attaches to an existing trash can. The sign becomes visible when the lid is lifted, with the goal of intercepting the moment of disposal with helpful cues like what to compost and why it matters.
Why It Works
- Fits into existing routines and setups – no behavior overhaul needed
- Reduces hesitation with built-in, moment-of-use signage
- Addresses space constraints for small apartments or dorms
Testing & Iteration
Feedback from a college student tester helped us refine clip size, consider freestanding versions, and propose add-ons like liners or drop-off maps to support long-term use.
