The bins were never the problem

A university wants to cut dining-hall waste. The brochure says 'sustainability, students, data'. Eighty teams will put sensors on bins. A cook tells you, offhand, that at 20:40 they throw whole trays because students will not take leftovers in front of their friends.

Where is the hack?

• aIoT weight sensors on every bin, dashboard for estates
• bAn app that gamifies not wasting food with points and a leaderboard
• cA way to claim leftovers at 20:40 without performing poverty — anonymous, ordinary, already in the line
• dA computer-vision model that classifies waste streams for a report
