Currently, the recycling of worn-out car tires is a serious problem. For example, world statistics on tire recycling showed the formation of more than 14.5 million tons of depreciated car tires per year. However, about 10% of used tires are recycled. Tire recycling by pyrolysis makes it possible to obtain fuels and lubricants, and the chamber residue represented by carbon often poses a threat to the environment as a pollutant. Therefore, the disposal of the resulting carbon black is a major problem. At the Navoi State University of Mining and Technology at the Department of Chemical Technology, the physico-mechanical properties of a carbon-saving material, which is a secondary raw material for the production of pyrolysis of worn tires, were analyzed, in turn, and the technological parameters of rubber mixtures based on SKI-3 and Nairit KR-50 rubbers were studied.

Oxidation-reduction processes are phenomena that occur continuously in nature. As a result of these processes, organic substances are converted into inorganic ones. Energy exchange in living organisms, thermal phenomena in physics, and electrical processes in nature are also related to oxidation-reduction processes. The essence of these processes is that the oxidation state of the particles that make up the substance changes during chemical reactions. This topic is mainly studied in depth in chemistry. This article provides valuable information on teaching oxidation-reduction processes.
