Dynamic flow analysis of current and future end-of-life vehicles generation and lead content in automobile shredder residue

Abstract

Since End-of-life vehicles (ELVs) contain toxic substances, they have to be treated properly. The purpose of this study was to obtain useful information for ELVs management from the viewpoint of toxicity. We focused on lead as a representative toxic substance contained in vehicles and investigated the dynamic substance flow of lead contained in ELVs and its content in automobile shredder residue (ASR). A population balance model was used to estimate the number of ELVs generated between FY (fiscal year) 1990-2020, employing a Weibull distribution for the lifespan distribution. 16 lead-containing components of the vehicle were considered. It was estimated that the annual number of ELVs generated would be 2.9 million as of FY2020. The results implied it is hard to remove Pb completely. This is because 5,000-11,000 t-Pb will still remain in vehicles in use in FY2020 even though most components in new model vehicles could be replaced by lead-free

Automotive shredder residue (ASR) management: An overview

“…If ELVs are not treated appropriately, hazardous compounds may remain in the shredder residue (Gonzalez-Fernandez et al, 2009;Yano et al, 2014).…”

End-of-life vehicle management: a comprehensive review

“…Lu et al [128] identified drivers for new joining solutions in the automotive industry and specifically reviewed the current use of adhesive technology in ELVs. Yano et al [129] investigated the dynamic substance flow of lead as a representative toxic substance in ELVs and ASR. They applied a population balance model for estimating the number of generated ELVs in Japan between fiscal years 1990-2020.…”

Recycling of End-of-Life Vehicles in Small Islands: The Case of Kinmen, Taiwan

“…There are statistical reports about the ELV collection amount in Taiwan, but the data for Kinmen and the generation amount is not clear. To quantify the number of ELVs generated from process (a) in Figure 1, we estimated the amount of ELV generation by the population balance model (PBM) developed by Tasaki et al [23], which is applied in many researches [24][25][26]. The PBM method estimated the future generation of waste durable goods by shipment number, possession number and lifespan distribution.…”
