Abstract: A composition comprising used chewing gum and a filler is provided, together with a method of preparing the same. In a preferred method, the chewing gum is subjected to a pre-treatment with an oil or water before being combined with the filler. In an alternative method, the chewing gum is used alone with the filler. A composition comprising used chewing gum, a filler and a polymer is also provided, together with a method of its preparation, in which a pre-mixture of the gum and filler is first prepared, before being combined with the polymer, preferably in a molding process. Articles prepared from a composition of used chewing gum, a filler and a polymer are also disclosed.

Abstract: A method for processing waste chewing gum to form granules, wherein the granules have a D50 diameter is provided, the method comprising the step of granulating the waste chewing gum in a granulator, the granulator having a screen comprising a plurality of rectangular holes through which the granulated material passes, wherein the holes have a side of length x; and where the following relationship applies: D50=A x2+B x+C??[Formula I] in which A, B and C are constants.
