Waste Tyre Co-Pyrolysis and Engine Performance of Tyre Pyrolysis Oil: A Review

Abstract

A comprehensive review that covers major works within a period of twenty-nine years (1990-2019) on waste tyre pyrolysis/copyrolysis and engine performance and emission characteristics of TPO was carried out in this study. A key issue with researchers remains on how to improve the oil yield and its quality. Waste tyre pyrolysis is established to be the most efficient and sustainable means of waste tyre disposal. It also serves as a source for alternative and renewable fuels and other by-products that can have valuable input in the industry. Co-pyrolysis is not associated with the huge burden of cost and as such is receiving particular attention. Significant research of interest that can bridge major gaps is in the co-pyrolysis of the waste tyre in combination with other wastes. There is still also the need to improve the works on engine performance and emission characteristics of TPO.
