Multiobjective waste management optimization strategy coupling life cycle assessment and genetic algorithms: Application to PET bottles

► A mathematical model based on life-cycle assessment (LCA) results is developed. ► The environmental efficiency of the end-of-life management of polyethyleneterephthalate (PET) bottles is assessed. ► Multiobjective optimization and decision support tools are used. ► Optimal targets for efficient waste management are defined.
