SCRAP TYRES AND EXPLOITATION OPTIONS FOR TYRE RUBBER MIX

Abstract

This paper deals with scrap tyre management and current exploitation routes. The disposal of tyre waste is increasing day by day at exponential rate. Exploitation of end-of-life tyres is a significant environmental issue and challenge for all countries. Rubber has long-term decay in natural conditions due to high durability for lot of climate or soil exposure and biological attacks. Scrap tyres within most countries are burned up nowadays, but this has generally negative influence. From an economic standpoint, however, the profit derived from energy recovery by tyre incineration would be offset by the expense of meeting pollution legislation. Scrap tyres can be utilized in various rubber applications. Recommended solution is to thermally reprocess tyre waste into valuable products. One of thermal processes is pyrolysis that tyre waste can be converted into crude gas, oil and solid products. For instance, solid product can be used as carbon black with quality improvements.
