Small choices,
big change.
SUST-I helps you swap unwanted items for free, find recycling points nearby, and identify recyclable materials with AI — all in one beautifully simple app.
SUST-I — pronounced “susti”.
About the project
Making sustainability the easy choice.
Every year, tons of usable items end up in landfills simply because people don't know where to take them — or who might need them. SUST-I was born as our senior design project to close that gap.
By combining community exchange, location services and on-device machine learning, we aim to make reusing and recycling as effortless as sending a message.
