Abstract
A method of reclaiming used tennis balls and transforming the material reclaimed from the tennis balls into soles for footwear. This multi-step process requires acquiring used tennis balls, grinding the tennis balls into ground rubber bits (usable elements) and tennis ball “fuzz” (unusable elements). The rubber and fuzz are passed through a screen which allows the rubber bits to exit the screen but retains the fuzz. The rubber is then mixed with an H2O and Polyurethane mixture to form a rubber mixture. This mixture is then pressed into a shape using a mold, cured, and then used to manufacture footwear.
