Abstract:
1. A plant for implementing a process for treating vulcanized-rubber waste, wherein the process for treating vulcanized-rubber waste includes the steps of: coarse cutting of said waste into fragments, attacking said fragments using a molten pure base under temperature conditions causing, in the presence of molten pure cast NaOH as the molten pure base, deconsolidation of the vulcanized rubber waste into deconsolidated solid fragments of polymeric composition: separating said molten base from said deconsolidated solid fragments; neutralizing said deconsolidated solid fragments; and recycling or reutilizing the neutralized, deconsolidated solid fragments wherein the plant forms a completely closed system, with no atmospheric pollution, the plant comprising: a device for melting said molten pure base; a reactor connected to said melting device, into which said vulcanized- rubber waste, which has been coarsely cut into pieces, and said molten pure base are introduced, and in which reactor temperature conditions are applied causing deconsolidation of the vulcanized-rubber waste into solid fragments of polymeric composition; a separating device connected to an outlet of said reactor and allowing the molten base to be separated from the deconsolidated solid fragments; a neutralizing device fed with neutralizing agent from a source of neutralizing agent, in which device the deconsolidated solid fragments are neutralized; and a device connected to the neutralizing device for sorting the neutralized, deconsolidated solid fragments.
