CBS Evening News traveled to Ohio Stadium and that team up north's stadium to keep the rivalry strong and see which team diverts the most waste from the landfill during and after home game days.
Lately, that's been Ohio State, where Mary Leciejewski is associate director of environmental sustainability.
"I mean, it just comes with the territory," Leciejewski said.
In this competition, armies of volunteers collect and sort through mountains of trash, separating what's recyclable from what's compostable, like food scraps and cups, forks and plates that are made to decompose over time.
Last season, Ohio State claimed two national titles: one in football and one in trash. The Buckeyes diverted 94% of game day waste away from the landfill, topping the Wolverines' 79%.
