“…Besides, many scientific articles propose the incorporation of wastewater sludge in the industrial production of ceramic tiles for various purposes, such as glazed, roof, and floor tiles. Considering the results of mechanical properties, water absorption, apparent density, and the other features obtained in some of the studies [ 19 ], sludge can be successfully added even at a percentage above 30% of the total final tile mix with no detrimental effects on the performance. More interestingly, Rodrigues and Holanda [ 20 ] concluded that integrating waste sludge as a replacement for kaolin by up to 10% can allow the production of ceramic floor tiles at lesser firing temperatures, which might lower manufacturing costs and have significant financial benefits in addition to the environmental ones.…”

“…Regarding this, it is important to note that almost all developed countries worldwide depend on concrete as one of the basic engineering materials in most building structures. Also, the concrete industry is one of the largest consumers of virgin raw materials of nature and, therefore, has a bad reputation in terms of ecology [ 19 ]. Moreover, concrete prices have risen drastically in the past decade due to high demand and production costs.…”

This research presented, for the first time, the results of the successful application of the waste press sludges, WSLP (plant for lacquer and paint) and WSEP (powdery enamel plant), from a wastewater treatment plant generated during heating device production in the construction industry. The results of WSEP characterization and its influence on cement paste, mortar, and concrete properties showed that this material could be used as a cement replacement (with a maximum replacement amount of 20%) in producing mortar and concrete. Although waste WSLP sludge does not possess pozzolanic properties and does not meet the criteria prescribed by the standards for application in mortar and concrete due to its chemical inertness and fineness, as well as its extended setting time, it can be used as a replacement for stone filler or other powdered mineral admixture in the production of self-compacting concrete (SCC) in amounts up to 100%, with a maximum quantity of up to 100 kg/m3. The obtained results indicate that with the appropriate conversion, waste sludges, despite representing hazardous waste, can be used as safe products in the construction industry; i.e., the waste material can become a useful and valuable raw material by applying (respecting) all of the principles of the green economy.

“…In general, an extensive literature survey evidenced that wastewater sludge is being widely investigated for a broad range of effective applications in numerous engineering fields. It has been reported to possess great potential to be applied as a component of construction materials [14][15][16][17], as an adsorbent for the removal of different pollutants present in soil and water [13], as fertilizers and ameliorants for an enhancement of the structure and properties of soil [13,18], and even as a potential sustainable biomass resource for energy production [19][20][21]. However, most of the mentioned research studies have been focused namely on municipal (sewage) wastewater sludge.…”

The Incorporation of Waste Sludge into the Production of High-Temperature-Resistant Adhesive Ceramic Materials

et al. 2023

In recent years, the interest of the scientific community has become focused on the integration of circular economy principles by eliminating end-of-life concepts and forming zero-waste strategies. The present paper suggests the possible application of innovative, eco-friendly, cost-effective, and highly efficient ceramic materials with the partial implementation of aluminosilicate-based waste in the form of wastewater sludge in advanced technology solutions. The specific objective was to demonstrate the effective utilization of the investigated waste in the production of refractory adhesives and/or sealants for Intermediate-Temperature Solid-Oxide Fuel Cells (IT-SOFCs). Different physical–mechanical and chemical properties were determined along with the performance of leaching tests, the thermal cycling procedure, and leakage tests in a single cell. Based on the maintenance of mechanical integrity after thermal cycling and satisfying crystal and microstructural stability after high-temperature treatment, it was concluded that the investigated materials may be considered promising candidates for application as heat-resistant adhesives for connecting components in heating systems. However, they were not found to be applicable as sealants for IT-SOFCs in raw form according to the failure of testing in a single cell. Still, requirements for this purpose could be met after certain modifications of the composition and synthesis methodology, which presents the major initiative for our further research in this field.

“…A sustainable approach is needed to face the challenge of the scarcity of these materials in the coming years, which will be aggravated by the excessive use of non-renewable resources [3][4][5]. Some alternatives to exploiting non-renewable natural resources include reusing building materials, replacing building materials with low environmental impact materials, and adopting eco-friendly materials such as recycled materials or waste [5][6][7]. In addition, adopting more efficient construction techniques, such as modular construction, can also benefit the sector as it can significantly reduce the waste of building materials [7,8].…”

In this study, we developed formulations of a ceramic coating from clay, kaolin, quartz, talc and feldspar as a standard formulation with the addition of eggshell residue to improve the mechanical characteristics of the product. The addition of eggshell residue is justified as it will contribute to filling the formulation’s interstices. It would also help decrease the sintering temperature due to the high presence of calcium oxide in its composition. Samples with the ceramic coating (45% by weight of feldspar; 30% by weight of clay; 15% by weight of kaolin; 7% by weight of quartz; 3% by weight of talc; and additions of 5%, 10% and 20% by weight of eggshell residue) were pressed uniaxially at 70 MPa for 30 s; dried at 110 °C for 24 h; and sintered at 1000 °C, 1100 °C and 1200 °C. The main mineralogical phases (microcline, mullite, quartz and anorthite) of the sintered samples were identified by X-ray diffraction (XRD). After evaluating the physical-mechanical properties (water absorption, linear shrinkage, apparent porosity and resistance to flexion), it was observed that the incorporation of eggshell residue (5%, 10% and 20%) resulted in a significant loss of the desired physical and mechanical properties. A loss of over 50% of mechanical strength was obtained.
