Recycle your used tennis balls today! Guts and Glory Tennis is your local tennis ball recycling center. When your tennis balls no longer offer the performance you are seeking, please consider recycling rather than throwing them away. (Did you know it takes approximately 450 years for a tennis ball to decompose in a landfill?) Feel free to stop by anytime and drop your used balls with us. It's that easy! We work with our friends at Rebounces for recycling as well as schools and nursing homes who regularly contact us seeking used tennis balls for the classroom chairs and patient walkers.
