  • Recycling tires has become relevant during the last decade because of an urgent need to create a
    circular economy for a more sustainable industry through the means of recovered raw materials.
    Worldwide 1,4 billion tires are sold and disposed every year. Through the thermolysis process, scrap
    tires can be valorized and its constitutive materials (steel, fuel (a gas and a condensable phase) and carbon black) can be recovered. The latter product obtained by this technique receives the name of Recovered carbon black (rCB). It contains carbon black and inorganic compounds used for tire
    fabrication. It is important to compare rCB to commonly used industrial carbon blacks to validate its industrial applications. On this study, eight EPDM based formulations were prepared using two
    different carbon black types– rCB and N650. An RPA was used to examine the effects that varying
    the type and concentration of filler had on the compound properties. This study presents rheological
    and tensile properties of such mixed compounds and discusses the application similarities and
    differences between a sustainable carbon black type versus a standard furnace grade. Results show
    significant mechanical and rheological differences between N650 and rCB. Depending on the application, rCB presents as a solution to adjust compound properties to achieve a specific manufacturing goal.
