END-OF-LIFE VEHICLES MANAGEMENT AND INITIAL ESTIMATION OF THE MATERIAL FLOW FROM ELV IN VIETNAM

Quang Duc Nguyen

Abstract


End-of-life vehicles (ELV) can be considered as a specific scrap source in Vietnam that is out of the Government control. This research is the initial research in Vietnam for the estimation of ELV flow and the determination of material flow from an ELV. For the estimation of ELV in Vietnam, a combination tool using the population balance model, logistic function and Weibull distribution is applied. It is estimated that the owner rate of car in household is quickly increased, and thus, increases the number of car and the ELV. By the 2030, the owner rate in household reach 0.13 unit per household, double it is in 2022 and 10 times higher in 2012. Up to 2030, nearly 190.000 passenger cars will be discarded, equals with the accumulated outdated automobiles up to 2019. In the case of a common passenger car, it is found that more than a half of an ELV (57%, in weight) can be reused in Vietnam, including mostly engine parts, wheels, air bag, speaker, chassis or mirror. About one third (32%) can be recycled as secondary material resources, including mostly metal parts, some types of plastic and rubber. The rest (11%) that cannot be reused or recycled is dumped without control around the dismantling site, causes many harmful impacts to environment and public health.

While ELV is classified into groups of equipment that are needed to retrieve and treat by the producers under Decision 16/2015/QĐ-TTg, Vietnam do not have any proper legislation to control this waste flow, as well as any formal facility to treat it. Thus, it is still hanging for Vietnamese Government to improve the legislation and management infrastructure for the application of Extended Producer Responsibility system to manage this type of waste.
