Editor’s note: A previous version of this story incorrectly stated the collection schedule based on outdated information. Recycling and yard trimmings will be picked up on alternating weeks in Atlanta. The story has been updated to reflect the correct information.

Atlanta residents who pulled their blue recycling bins to the curb Monday may have been surprised to see they were still full at the end of the day.

That’s because recycling in Atlanta isn’t being picked up this week. Announced earlier this month, the city is reducing recycling and yard trimming pickups to every other week, for at least the next three months. Trash will continue to be picked up every week.

Recycling and yard trimmings will be picked up on alternating weeks.

The city did not specify why the pickups are being reduced, but suggested it could be tied to COVID-19 cases among Department of Public Works employees.

“As COVID-19 cases continue to rise nationally and locally and directly impact our solid waste frontline workers, DPW has implemented service changes to help mitigate the adverse health and safety effects on employees while continuing to provide quality, effective and efficient services to residents,” the department said in a notice.

Future schedule changes “will be made based on the number of COVID-19 cases experienced by the department.”
