SAN FRANCISCO (AP) — What takes years to make and costs more than $20,000? A trash can in San Francisco. The pricey, boxy bin is one of three custom-made trash cans the city is testing this summer as part of its yearslong search for another tool to use against its dirty streets. San Francisco began its search for the perfect trash can in 2018 when officials decided it was time to replace the more than 3,000 round public bins that have been on the streets for nearly 20 years. What trash can the city gets will depend in part on the feedback from residents. The city promises the new bins will be in place by the end of 2023 and will cost a maximum of $3,000 each.
