The aim of this work is to analyze the impact and the potentials of multiple criteria decision-making methods (MCDM) especially focusing on its application in the field of sustainable solutions to waste problems. To demonstrate the applicability of MCDM methods in the field of mineral processing, the fly ash pellets selection problem was considered. Studies reported in this paper used three selected size fractions of pelletized fly ash, from power plant Nikola Tesla —B, Obrenovac, obtained at different amounts of the binder. Physical-mechanical properties of pellets samples were tested, afterwards the complex methods of multi-criteria decision making was presented, with the objective to determine adequate pellets for producing lightweight concrete. The criteria weighting was performed firstly, by AHP method, afterwards a decision model was applied, by using TOPSIS method. Fly ash pellets were ranked and the results obtained that the best pellet quality was archived for mean diameter (D...9) of 11.21 mm and 8.36 mm, with compressive strength
of 6 MPa.
