Method of recycling vulcanized rubber

A method of recycling vulcanized rubber comprises the steps of:

• providing a quantity of vulcanized rubber, a glycerol and hydrochloric acid solution, and a reactor;
• grinding the quantity of vulcanized rubber from a macroscopic particle size to a smaller diameter;
• filling the reactor with the glycerol and hydrochloric acid solution;
• submerging the quantity of vulcanized rubber within the glycerol and hydrochloric acid solution in order to form a preparatory mixture;
• decomposing the quantity of vulcanized rubber by simultaneously heating and agitating the preparatory mixture in order to chemically break sulfide bonds within the quantity of vulcanized rubber;
• separating a solid residue from a decomposed preparatory mixture, wherein the decomposed preparatory mixture includes a smaller quantity of vulcanized rubber, a quantity of de-vulcanized rubber, and the glycerol and hydrochloric acid solution;
• mixing an additional quantity of hydrochloric acid into the decomposed preparatory mixture within the reactor;
• decomposing the smaller quantity of vulcanized rubber by simultaneously reheating and agitating the decomposed preparatory mixture in order to chemically break sulfide bonds within the smaller quantity of vulcanized rubber;
• and recovering a full quantity of de-vulcanized rubber from the reactor through a solid-liquid separation process.
