Used tires recycle management and processing: a review

Abstract

Abstract The number of used tires in the world is projected to increase in the future due to an incrementing number of cars and motorcycles particularly in developing countries such as Indonesia. This situation can endanger the environment and public health since it poses a high risk for fires. Despite the environmental impacts, used tires present economic values. This can be achieved by processing it into several forms such as tire-derived fuel, asphalt rubber, and rubber-plastic products. Furthermore, to collect used tires from tire users and send it into used tires recycler, management scheme is required. This paper aims to review the development of used tires recycle management and processing. It has been found that several management schemes for recycling used tires have been identified from literature including Extended Producer Responsibility (EPR), Free Market, and Government. Moreover, several processes to recycle used tires were identified, such as: retreading, energy recovery, product recycling, material recycling, and pyrolysis.
