economy viewpoint, avoiding landfill disposal. This is particularly true for mortars with recycled aggregates, which can still perform the same functions and have the same strength classes of the original ones made with raw materials [6; 7]. The choice of the mix design of mortars is particularly important for the LCA [8], especially the choice of components to be, totally or partially, replaced with others entailing lower impacts [9; 10] or with recycled or reused ones [11; 12; 13; 14]. Different approaches can be used to reduce the environmental impacts of mortars, which involve the possibility of using substitutions for the binder, the aggregates, and even the additives. In mortar mixtures, using Portland Cement, air line, or natural hydraulic lime makes an important difference in terms of environmental impact [15]. The type, content, and strength class of the cement directly affect the environmental impact [15; 16]. Portland Cement is the most widespread binder with the largest contribution to the Global Warming Potential [15]; for this reason several researchers investigated ways to replace it, for instance, with forest biomass ashes [6] or fly ash [17]. A recent study shows that geopolymers can be used as the binder in mortar mixtures with important environmental results, as their reaction is carried out at a moderate temperature [9]. Other researchers studied the possibility of incorporating waste materials into mortars as aggregates [6; 17], considering that sand is the component that is present in the greatest quantities [7] in mortars Construction and demolitions waste (CDW) [11], ceramic [18; 19], sanitary ware [6; 20], glass fiber reinforced polymer [6; 21], ornamental rocks [22], cork [18; 23], and expanded polystyrene [24; 25] have been incorporated into mortars as substitutes for sand, still achieving good technical performance in mortars. Evaluation of the environmental behavior of mortars should be performed based on the well-established criteria of LCA [26; 27; 28] for identifying the impacts through the entire life cycle of the material [1; 10; 29]. However, when analyzing mortars with recycled aggregates, research has shown the importance of considering and evaluating the environmental benefits, in relation to the avoided disposal of recycled materials, to the transport from factory to landfill, and to saving natural resources and raw materials [30]. [PERSON] et al. conducted an LCA of 19 mortars obtained by replacing different percentages of cement and/or sand with waste materials, using a reference mortar for comparison, all belonging to the same strength class [6]. Sixteen of 19 analyzed mortars showed better environmental performance than the reference one, according to all the impact categories considered. The three remaining mortars presented a greater ADP (fossil) impact, due to the high transport distance of wastes. [PERSON] et al. formulated 12 restoration mortars, using different binders and (calcareous and silica) sand typologies and substituting the regular additive with a recycled one obtained with waste glass powder and crushed bricks [15]. Results showed that Portland Cement and air line CL90 binders were the constituents with the largest contribution to the analyzed environmental impact categories, and that transportation distance of raw materials was one of the main parameters affecting results [15]. These studies suggest that great care should be taken in assessing environmental impacts linked to transportation and to re-processing of secondary materials, as it is not guaranteed that mortars produced with recycled materials are always the most sustainable ones [12; 14]. In particular, literature suggests that transportation may considerably influence the environmental performance of construction materials [17; 30]; therefore, it should be deeply investigated according to the goal and scope of the study.
