Assessment of human health impact based on life cycle assessment: A case study of Thai retread tire

Abstract

© Published under licence by IOP Publishing Ltd. The sustainable production of tire supply chain has been recently highlighted to reduce the environmental and human health impacts. The main environment problem of tire supply chain is waste treatment. When the tires reach the end of their working life, they are recycled (obtaining raw materials and other components for certain manufacturing processes) or burned (obtaining energy). During the exploitation, a tire with worn tread can be processed in a certain way to allow its reuse. The retreated tire should be accepted for further treatment. Hence, this study conducted the human health impacts of retread tire using life cycle assessment. The recipe2016 technique and Sigmaoro 9.0 software were used as the method of human health assessment. The result showed that the total value of human health impact assessment for retreated tire production were 4.3007E-06 Daly. The hotspot of human health impact for retreated tire production was tire material and electricity consumption. Form this finding will help designers or managers recommend the installation scenario of retreated tire production by considering human health impacts.
