ABSTRACT

Post-disaster activities mostly involve the reconstruction phase. This phase is quite long and costs are very high. In the immediate aftermath of the disaster, already frayed economies seek resources to cover the cost of new structures. However, the remaining debris after disasters can be used by recycling for restructuring and can be brought into the economy. In this study, according to a possible Istanbul earthquake scenario, the recycling of the debris was evaluated by two multi-criteria decision-making methods and it was determined that correct separation could prove a serious gain both to post-disaster activities and the economy. The determined criteria were weighted using the SWARA method, and the prioritization and ranking of alternative materials were provided by the CoCoSo method. As a result, it was determined that concrete, steel, and bricks will contribute primarily to restructuring and the economy after separation; changes in the criterion weights were examined in a sensitivity analysis.
