“…3) shows the continuing of the sintering interval of composition. This composition S2 according to their presented relations between bulk density and thermal shrinkage could be the optimal for production of glass-ceramics while this shows the similar properties to other previously investigated glass-ceramics (Rozenstrauha et al 2011) and could be suitable for running ceramic's production technologies without significant changes.…”

The sewage sludge from a water purification plant was analysed for recycling to the dense glass-ceramic materials. The sewage sludge containing aluminium compounds and circa 50 % of organic matter was used as a filler, but as the matrix of glass-ceramic was examined an illitic clay from Liepa deposit (Latvia). The raw materials were investigated by differential-thermal (DTA) and X-ray diffraction analysis (XRD). The dense glass-ceramic was produced from the water purification sewage sludge and limeless clay in ratio 10-40 : 90-60. The optimal values of bulk density (2.28 g/cm 3 ) and thermal shrinkage (29 %) for novel materials were observed for glass-ceramic with the sludge additive at amount of 20 wt %, obtained by sintering at temperature 1140 °C. The relationship between thermal treatment conditions and maximal treatment temperature was established. The following crystalline phases for novel materials were detected by XRD analysis: microcline (KAlSi 3 O 8 ), hematite (Fe 2 O 3 ), quartz (SiO 2 ) and corundum (Al 2 O 3 ). The physical-chemical properties of novel materials correspond to the dense glass-ceramics composite while the material itself could be applied as building material.

“…Previously made materials from Latvian industrial waste were chosen as starting substances for pellets -A5, B5 and E k 2. Pellets consisted from: A/S Valmieras stikla skiedra sewage sludge, glass waste, steel cooling refuse from Liepajas metalurgs, alumina process waste, illite limless clay from Apriki and Kuprava [9,10].…”

This work focuses on pellets made by Latvian industrial waste (waste cullet glass, sewage sludge, metallurgical slag and alumina scrap metal processing waste and raw mineral materials (limeless clay) to gain high porosity and water sorptiom. Iron sorption using ceramic pellets is explored more detailed. Physical-chemical properties and microstructure were researched to obtain a deeper understanding of how these qualities affect water purification from iron compounds. Three pellets with different properties were made in this paper : B5, A5 and E1. Composition B5 indicates highest iron sorption rate at sintering temperature 1100 °C and shows considerable iron reduction in a solution after one week.

“…They found that the calcined tile body containing LCD waste glass had a dense microstructure and had positive influences on tile specimens such as water absorption and the thermal expansion coefficient. Rozenstrauha et al (2011) spotted a dense glass–ceramics composite on SSA/glass ceramics at temperatures between 1120 and 1140 °C [ 31 ]. Esmeray and Atis (2019) used sewage sludge, oven slag, and fly ash in clay brick production; however, putting sewage sludge appears to have a negative effect on the strength of the final products, so its use should not exceed 20% [ 32 ].…”

Applying Mixture of Municipal Incinerator Bottom Ash and Sewage Sludge Ash for Ceramic Tile Manufacturing

et al. 2021

Municipal incinerator bottom ash (MIBA) and sewage sludge ash (SSA) are secondary wastes produced from municipal incinerators. Landfills, disposal at sea, and agricultural use have been the major outlets for these secondary wastes. As global emphasis on sustainability arises, many have called for an increasing reuse of waste materials as valuable resources. In this study, MIBA and SSA were mixed with clay for ceramic tile manufacturing in this study. Raw materials firstly went through TCLP (Toxicity Characteristic Leaching Procedure) to ensure their feasibility for reuse. From scanning electron microscopy (SEM), clay’s smooth surface was contrasted with the porous surface of MIBA and SSA, which led to a higher water requirement for the mixing. Specimens with five MIBA mix percentages of 0%, 5%, 10%, 15%, and 20% (wt) and three SSA mix percentages of 0%, 10%, and 20% (wt) were made to compare how the two waste materials affected the quality of the final product and to what extent. Shrinkage tests showed that MIBA and SSA contributed oppositely to tile shrinkage, as more MIBA reduced tile shrinkage, while more SSA encouraged tile shrinkage. However, as the kiln temperature reached 1150 °C, the SiO2-rich SSA adversely reduced the shrinkage due to the glass phase that formed to expand the tile instead. Both MIBA and SSA increased water tile absorption and reduced its bending strength and wear resistance. Increasing the kiln temperature could effectively improve the water absorption, bending strength, and wear resistance of high MIBA and SSA mixes, as SEM showed a more compact structure at higher temperatures. However, when the temperature reached 1100 °C, more pores appeared and seemingly exhausted the benefit brought by the higher temperature. Complex interactions between kiln temperature and MIBA/SSA mix percentage bring unpredictable performance of tile shrinkage, bending strength, and water absorption, which makes it very challenging to create a sample meeting all the specification requirements. We conclude that a mix with up to 20% of SSA and 5% of MIBA could result in quality tiles meeting the requirements for interior or exterior flooring applications when the kiln temperature is carefully controlled.
