Abstract

Materials used by the automotive industry in particular and the transportation industry, in general, are selected based on a set of technical demands, customer demands, legal requirements, and ecological needs. Such needs include fuel efficiency, reduced emissions, weight reduction, used vehicle disposal, and the recyclability of its components. Hence, these materials are required to further accommodate specific emerging and traditional requirements that are not only essential to assess the material type and mix, when manufacturing these vehicles, but also necessary to determine its cost and its ultimate compatibility regarding recycling. In this study, the recycling of the main automotive structural materials is surveyed and assessed for two specific scenarios; aluminum-intensive and steel-intensive body structures. The deployed assessment in presented work computes the amount of energy required to recycle each vehicle structure and the cost incurred for these scenarios. The cost to energy utilized when recycling such vehicles is proposed as a parametric indicator of the recycling process. The survey part of the study highlights the ecological aspects of the automobile and further analyzes the material selection aspects and the Industrial Ecology IE aspects too. The assessment also covers the main light-weight alternatives including the high strength steel alloys, the variety of aluminum alloys and plastics. The survey features the different recycling systems from Type I to Quasicircular to completely circular material flow.
