Repair or rehome an item instead of throwing it away.
Tech partner
The world generates over 60 million tonnes of e-waste a year — and less than a quarter of it is properly recycled.
When repair shops, take-back schemes, and resale channels are too fragmented to find, broken electronics pile up in drawers, reusable clothes and materials go to the curb, and throwing things away stays the easiest option — feeding the 60+ million tonnes of e-waste a year, less than a quarter of it properly recycled.

What to build
Your Mission
Build an AI-powered solution that makes repairing or rehoming an item easier than throwing it away.
A static directory of recyclers or a search that returns dead links and closed shops still sends people to the curb. The gap is a confirmed, practical route: a working repair cafe, a certified recycler, a take-back program, or a resale channel for this exact item and location — without wasted trips.
How to build
Master the Challenge in 2 days.
Day 1
Find your personal angle on the problem.
Pick the smallest experience that helps someone repair or rehome an item instead of throwing it away. The goal is to make one of those experiences work well, not to solve every part of the problem at once.
- Finds circular-economy services around an item and location
- Verifies each candidate is still operating and accepts the item type
- Enriches matches with practical details like hours
Pick your angle
Day 2
Prototype a minimal possible solution.
Choose the simplest format that fits the experience and audience. Build only what you need to test whether the idea works, people can use it, or the system can deliver.
- A no-code prototype in Lovable, Bolt, or v0
- A working app in Cursor
- A custom-coded solution — Exa can sit underneath as a retrieval layer finding repair cafes, recyclers, and take-back programs, verifying they still operate and accept the item, and enriching matches with hours and cost
