Problem

A third of all food gets thrown away, often on a guess.

Wasted food uses up resources and contributes up to 10% of greenhouse gas emissions. People often can’t tell whether food is still safe to eat, so it goes in the bin.

Sketch development

Form and grip exploration

A one-handed body with a fold-out stand, a clear READY state, and a sensor head that sits close to the food without touching it.

Storyboard

Scan, result, reward

Unsure whether the leftovers are safe, the user scans them for an instant result. A green light means the food is safe, adds reward points, and saves another unnecessary bin trip.

Three states

The result reads at a glance.

97% · Safe to eat
Green ring, points added, and the CO₂ the user avoided by not binning it.
48% · Uncertain
The database can’t verify the extent of contamination, so the device says so rather than guessing.
14% · Likely contaminated
Red ring, with composting suggested instead of the bin.
