Cal Athletics teamed up with Cal Zero Waste, Levy, Pepsi and r.World Reusables to make football game days zero waste. Levy served drinks at California Memorial Stadium from durable, reusable plastic cups. Fans deposited cups into clearly marked return bins at the game, while r.World collected, sanitized and returned them for the next game. This change diverted thousands of cups away from the landfill, cut greenhouse gas emissions from production and disposal, and reduced litter.
