SCRAP TIRE DISPOSAL PROCEDURES

This is a comprehensive bibliography-based review of techniques possible and currently used per disposal and utilization of scrap tires. The general discussion covers the following topics - introduction; history; statistics; legal aspects; industrial action; ideal solution; scrap tires as a raw material; options; source control; landfill; retreads. Physical procedures discussed cover - size reduction (mechanical, cryogenic, ground rubber); fish reefs; barriers; and miscellaneous. Chemical procedures considered in more detail are - reclaim; pyrolysis (inert atmosphere, oxidative pyrolysis, steam atmosphere, molten salt, pyrolysis reactor design); asphalt component; carbon black feedstock; depolymerized scrap rubber; microbiological degradation. Scrap tire incineration and fuel value, It is concluded that for the immediate future, scrap rubber is best disposed of by incineration as a supplement for coal or other fuel.; Many procedures and processes for the disposal of scrap tires are available. Because of the complexity of the whole disposal problem - e.g., collection logistics, availability and location of markets for products generated from scrap tires, as well as economics - no one procedure or process is believed to be sufficiently outstanding that all scrap tires could be so processed. Several procedures or processes must be used to solve this industry problem. The procedure or process selected for disposing of scrap tires will be dictated primarily by economics and geographic location.
