The mass flow of waste tires grows with the increasing a number of vehicles on the roads.. This trend also holds in Vietnam. Currently, the waste-tires are collected, reused and recycled in several ways. This study carried out an investigation of waste tire generation collection, reuse and recycling in the South-East of Vietnam. Pyrolysis approach had been applied in some countries and Vietnam now a day. The study had also use Life Cycle Assessment (LCA) method with Simapro solfware (Version 220.127.116.11) to calculate and evaluate the environmental impacts from the waste tires pyrolysis process. The results found that there are large savings from waste tire pyrolysis in terms of material and emissions, due to the substitution of pyrolysis products. The findings from this study are: Waste tire is not completed as waste, it can be seen as a byproduct which can be reused or applied as an input material to become other useful products. A sustainable approach for waste tires, based on collection, reuse, recycling, and utilization of scrap tire and appropriate management, can achieve the goal of almost zero discharge of waste tires.
