Abstract: The objective of this work is to convert waste into products with economic values within the framework of sustainable development. To this end, vacuum pyrolysis, a thermal degradation route, makes it possible to recover value added products from used tires. Among the main products mention is made of pyrolytic carbon black which is used as a reinforcing filler in tires at a rate of 25-30 wt%. Carbon black is an essential material in several industrial fields, particularly in rubber factories as a reinforcement for increased stiffness and abrasion resistance thanks to its structural properties and chemical activity. The chemical composition of pyrolytic carbon black is altered due to residual carbonaceous deposits on its surface, which leads to a loss of chemical activity. Modifications have been considered in order to activate the surface of these particles, in particular the structural properties and the chemical composition of these fillers with functionalization techniques. The objective of the study is to develop a novel functionalization method to modify the surface of carbon black particles. The Catalytic Grafting method was evaluated, which would make it possible to graft more functional groups while greatly reducing the costs associated with functionalization, since no subsequent pyrolysis procedure is required. It consists in growing oligomers of the target polymer in the composite on the surface to compatibilize the solid with the polymer. The composite systems that are possible with these recycled fillers are numerous and varied, depending on the nature of the polymer and the production technology of the composite material. The fields of application are also very vast and expanding with, for example, the advent of 3D printing in which the thermoplastic yarns used are increasingly loaded with particles to improve the properties of the manufactured parts.
