The marble industry can cause significant environmental impacts due to quarrying, transportation, and shaping of marble. Marble extraction can disrupt the ecological balance of the mining area, from visual and noise pollution to surface and groundwater and agricultural land contamination due to the marble waste. In particular, waste marble dust (WMD) can be carried by the wind into residential areas and cause pollution. However, it can be used directly and recycled in the construction materials. This approach can have many environmental and economic benefits with the production of construction materials. On the other hand, the use of WMD as a substitute material in the construction sector was mainly analyzed for durability, workability, and strength; also, it can be a convenient option as a filler, but the environmental assessment of its use as a filler concrete is limited. This study evaluates using WMD by substituting different proportions of cement and fly ash (FA) in self-compacting concrete. CCaLC2 software was used in a cradle-to-gate assessment. When the amount of WMD used increases from 50 to 200 kg/m3, carbon footprint, acidification, eutrophication, photochemical smog, and human toxicity potentials of the raw materials increases 1,80%,236,97%, 26,48%, 221,48%, 102,22%, respectively. Considering the location of the marble mine and the marble waste storage area, using WMD instead of FA and cement in concrete can save environmental pollution from the clinker process in cement production. In addition, the transport of WMD can be seen as an economical alternative due to its low bulk density and reduced landfill.
