Game day recycling is the idea that having large crowds of people in a small, concentrated space will generate great amounts of trash and products that need to be recycled. On college campuses with large stadiums, a home football game can attract up to about 110,000 people, like the University of Michigan’s stadium. However, because colleges only play a limited number of games at home each season, the recycling programs specifically for game days are usually specialized and separate from the school’s regular recycling program.
