Prato de Rua used a sticker to turn Rio dumpsters into leftover-food handoff points

A March 2017 Fast Company article describes Prato de Rua (Street Dish), an initiative by a Brazilian collective called the Makers Society. Anonymous members affix stickers to the side of dumpsters in Rio de Janeiro, asking people to hang leftover food on the bin instead of throwing it away.

Fast Company reports that many of Rio's poorest people scavenge dumpsters and back alleys for meals. By designating exchange sites where they already look, the project hopes to spare them the effort of searching through a dumpster, and get others thinking about where excess food goes and who it could benefit.

The Makers Society also created a printable version of the sticker so that people in other cities can download it, attach it to a bin and spread the movement.

Hungry people already look for food at dumpsters, so no new site is needed.

A hung bag spares people a dig through trash.

A cheap printable sticker lets anyone in any city copy the idea.

Instead of building a new distribution channel, label the one that already exists and change what people do at it.

The article reports no usage figures or results; it only says the sticker was made printable so it could spread to other cities.
