San Francisco's public trash cans have long outlived their lifespan and need to be replaced.

The garbage receptacles also get rummaged through by scavengers, who leave behind a mess. To alleviate the issues, in 2018, San Francisco Public Works officials set out in search of a perfect trash can. The quest proved harder than they had thought.
