Pyrolysis is a widespread recycling technology of polymeric waste. Used tires being pyrolysis lead to the formation of three components: fuel fraction which being subjected to purification to yield gasoline and diesel fuel, steel wire which is recycled and carbon black that is accumulated contaminating the environment. This is explained by the specific properties of carbon black: small, hydrophobic particles that easily disperse and pollute the environment, is a possible carcinogen for humans, and short-term exposure to high concentrations can cause discomfort in the upper respiratory tract. At the same time, the carbon black obtained from tire pyrolysis contains a significant amount of fuel and is not miscible in polar solvents such as water. This makes the field of use of carbon black is narrow - is needed remove adsorbed fuel from particles and render them hydrophilic properties, thus obtaining a black pigment, the fields of use of which substantially increase: pigment for the production of pavement, decorative mortar, lacquers and paints, supplement for construction and repair of road. Studied tire pyrolysis residue is a homogeneous, finely dispersed, water-immiscible black substance. In order to assess the thermal stability of the residue, thermal analysis was performed in a dynamic air atmosphere. The results of thermal analysis show that the residue is stable up to 320 oC and total thermal degradation takes place at 750 oC, the carbon black begins to lose weight as soon as heating begins, the process continuing at temperatures above 300 °C; this is explained by the increased content of volatile substances that have not been completely discharged during pyrolysis. From thermal analysis was established that the carbon black contains 15% flammable volatile substances, oxygen oxidation of the surface in the air begins at 320 oC and total degradation takes place at temperatures above 430 oC. As a result of thermal degradation of soot no solid residue is formed. Based on the results of the thermal analysis, preventive degassing of the soot at 200-250 oC is recommended for evacuate volatile substances to prevent their accumulation and explosion. Oxidation with air is recommended to be carried out at 350-400 oC by continuous mixing to obtain a homogeneous product.
