Abstract

Highlights: Review of works related to management of ELVs and treatment of ASR. Sustainable management perspective of ELVs and ASR. Overview of ASR pre-treatment to reduce pollutant release before treatment or disposal. Overview of treatment processes to improve material and energy recovery from ASR. Findings of life cycle assessment (LCA) applied on ELVs and ASR treatment. Abstract: On the basis of statistical data, approximately 6.5 million tons of ELVs were produced in Europe in 2011. ELVs are processed according to a treatment scheme comprising three main phases: depollution, dismantling and shredding. The ferrous fraction represents about 70–75% of the total shredded output, while nonferrous metals represent about 5%. The remaining 20–25% is referred to as automotive shredder residue (ASR). ASR is largely landfilled due to its heterogeneous and complex matrix. With a start date of January 1st 2015, the European Directive 2000 /53/EC establishes the reuse and recovery of a minimum of 95% ELV total weight. To reach these targets various post-shredder technologies have been developed with the aim of improving recovery of materials and energy from ASR. In order to evaluate the environmental impacts of different management options of ELVs, the life cycle assessment (LCA) methodology has been applied taking into account the potential implication of sustainable design of vehicles and treatment of residues after shredding of ELVs. Findings obtained reveal that a combination of recycling and energy recovery is required to achieve European targets, with landfilling being viewed as the least preferred option. The aim of this work is to provide a general overview of the recent development of management of ELVs and treatment of ASR with a view to minimizing the amount of residues disposed of in landfill.
