Ultimately, what trash can the city gets will depend on feedback from sanitation employees, and the surveys completed by the end of September, Rubenstein said. The new cans are not expected on the streets until the end of 2023.
Diane Torkelson, who often picks up trash in her Inner Richmond neighborhood with other volunteers, recently trekked 5 miles (8 kilometers) with a dozen other civic-minded San Franciscans to examine three of the cans.
The two prototypes were already full when the group arrived to check them out, she said.
"If the trash can is full, it's of no use, no matter how well it was designed," she said.
