“…140 % up to 1150 °C). For comparison, laboratory prepared samples of clay-bricks with us much as 6 % olive-mill wastewater sludge were also reported to successfully undergo mechanical and environmental tests [10]. Savings of raw materials into ceramic samples incorporated with wet pomace from olive oil industry are further referenced in the scientific literature, with the best results obtained for 3 wt % addition [11,12].…”

“…Introduction of olive-mill solid residue into clay-based ceramics can be considered as a promising alternative solution for the valorization of this solid residue. Effluent olive-mill wastewater sludge was already embedded into fired laboratory produced clay bricks by Hamza et al [10]. Moreover, Cotes Palomino et al [11,12] have studied the influence of the amount of wet pomace (containing water, olive stone and pulp residue) into ceramics materials for optimization of their technological properties in order to meet the standards for use as structural construction bricks.…”

In the current research, the valorization of olive mill solid waste as beneficial admixture into clay bodies for developing greener ceramic materials with lower thermal conductivity, thus with increased thermal insulation capacity towards energy savings, is investigated. Various clay/waste mixtures were prepared. The raw material mixtures were characterized and subjected to thermal gravimetric analysis, in order to optimize the mineral composition and maintain calcium and magnesium oxides content to a minimum. Test specimens were formed employing extrusion and then sintering procedure at different peak temperatures. Apparent density, water absorption capability, mechanical strength, porosity and thermal conductivity were determined on sintered specimens and examined in relation to the waste percentage and sintering temperature. The experimental results showed that ceramic production from clay/olive-mill solid waste mixtures is feasible. In fact, the mechanical properties are not significantly impacted with the incorporation of the waste in the ceramic body. However, the thermal conductivity decreases significantly, which can be of particular interest for thermal insulating materials development. Furthermore, the shape of the produced ceramics does not appear to change with the sintering temperature increase.
