The statements, opinions and data contained in the journals are solely Therefore, the main problem associated with TPE production from recycled materials via melt blending is the low affinity and interaction between the thermoplastic matrix and the crosslinked rubber. Therefore, the investigation of end-of-life rubber processing methods is of high importance for both manufacturers and recyclers of rubber materials. In this paper, we review existing methods for processing of end-of-life tires, in order to obtain rubber crumb, which can later be used in the production of new industrial rubber goods and composites. We consider processes for separating end-of-life tires into fractions (in terms of types of materials) using chemical, mechanochemical, and mechanical methods to process the materials of used tires, in order to obtain crumb rubber of various fractions and chemical reactivities. These methods were reclamation, surface modification, use of rubber powder in asphalt paving, or as extender, or to produce filler to reduce the cost. Here briefly focus on why waste reduction and recycling is important; and determine methods to reduce, recycle and reuse items. Complicate the recycling process through the Tripartate discussion between DOE/MRB/Industry. This leads to phase separation and weak adhesion between both phases. 'Recyclable' waste has lowest recycling rates in plastic (7 5%), rubber (5 4%) and wood (4 6%) wastes. The statements, opinions and data contained in the journal, © 1996-2021 MDPI (Basel, Switzerland) unless otherwise stated. Methods of recycling depend on the content and include waste incineration, burial in designated areas, dumping at sea. However, their waste (materials after their end of life) do not degrade and remain for a long period of time in the environment. Despite technological developments, modern methods for the disposal of end-of-life tires most often involve either their incineration in cement kilns or the destruction of tires in special landfills, demonstrating a lack of sustainable recycling of this valuable material.
