Where Did All the Trash Cans Go?Intermediate

Finding a place to throw away a coffee cup can be surprisingly difficult in big cities. In San Francisco and Seoul, people often walk many blocks without seeing a single trash can. This creates a frustrating problem for residents and tourists.

This shortage is not an accident. Both cities removed many public bins on purpose. City officials believed that having fewer trash cans would make streets cleaner. They thought people would learn to carry their trash home instead of littering.

Danny Sauter discovered how much this bothered people during his 2024 campaign for San Francisco city supervisor. He expected voters to talk about housing costs and homelessness. Instead, people kept complaining about missing trash cans. They told him that bins they had used for years suddenly disappeared. After he won the election, Sauter asked the city to add 1,500 new trash cans to his district.

San Francisco started removing bins in the mid-2000s. The city had about 5,000 public trash cans, but the mayor decided to remove over a third of them. He was inspired by Tokyo, where streets are very clean even though there are almost no public bins. The idea was simple: if there are fewer trash cans, people cannot dump their household garbage in them illegally.

Seoul had similar reasoning but for different reasons. In 1995, South Korea created a new system where residents must buy special bags for their trash and pay by volume. Many people didn't want to pay for these bags, so they started throwing away their household trash in public bins for free. This prompted Seoul to remove thousands of bins from streets and subway stations. The number dropped from over 7,600 to under 5,000.

Both cities expected people to change their behavior and carry trash home like people do in Tokyo. But this didn't happen. Tokyo's clean streets depend on strong cultural habits that developed over many generations. San Francisco and Seoul didn't have these same traditions. Instead, trash ended up in alleys, flower pots, and around the few remaining bins.

Other cities tested similar ideas. Philadelphia studied different numbers of bins in parks and shopping areas. The results were clear: more bins meant less litter, and fewer bins meant more litter. New York removed bins from some subway stations and later found that fires on subway train tracks increased by 33%.

Cities like Washington, D.C. and Portland took a different approach. They added more bins and kept their streets cleaner. Washington has about 6,600 public trash cans, more than twice as many as San Francisco.

Now both San Francisco and Seoul are changing their plans. They are adding new, better-designed trash cans back to their streets. Seoul plans to have thousands more bins by focusing on tourist areas.

The lesson is becoming clear: making it easy for people to throw things away works better than making it difficult. Simple solutions often work better than clever ideas.

1. Have you ever had trouble finding a trash can in a city?
