Due to the growing amount of residues generated from Municipal Solid Waste Incineration (MSWI) and the low accessibility of landfill disposal, it is mandatory to provide a sustainable alternative for managing wastes contributing to the efficient use of resources that can help to save our polluted environment. From this point of view, our proposed idea is to transform the bottom ash into useful construction material as aggregates or light weight aggregates that can be considered as a renewable resource. Moreover, this type of aggregate can help to save our atmosphere from the produced wastes, decrease the quantity of aggregates excavated form quarries and limit the importation of manufactured lightweight aggregates from outside our country Lebanon. Our aim in this paper is to manufacture artificial lightweight aggregates from bottom ash using different proportions of binder, to study their physical and mechanical characteristics and to find out the optimal sample of aggregates made from residues based on their performance and cost analysis. Afterward, the performance of concrete made of selected artificial aggregates was studied through an experimental testing program and compared to that of concrete made by a conventional Expanded Clay lightweight aggregates and normal weight aggregates.
