An ECO Recycling Bin stolen from the baseball field across from Allyn Brook Park in Durham was returned on Friday, according to ECO advisor Susan Michael.
Michael reported the bin missing on Wednesday.
It's not clear who took the container.
The Environmental Coginchaug Organization around the school's Athletic Complex and Allyn Brook Park last month, as part of a fundraising effort and to encourage recycling.
According to Michael the ECO club recently collected 188 bottles, including 130 for deposit and 58 others that will be recycled, from the bins.
The club will document their efforts and present the results to the Rockfall Foundation later this year, which provided a grant to help pay for the recycling bins.
