AB  - 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.

AB  - The management of industrial solid waste is regulated through several legal acts in Serbia, and in the last few years intensive work has been done to improve the legal norms that regulate the conversion of waste into materials that are no longer waste, in order to achieve the goals, set by the Green Agenda and the National Waste Management Plan. This paper provides an overview of the legal regulations which are regulating waste management, with special reference to acts and articles of acts that regulate the reuse and recovery of solid industrial waste. Possible obstacles and doubts that may arise when interpreting legal provisions are listed, with a focus on similarities and differences in the guidelines for converting waste into a by-product and material with and of waste status, the possibility of hazardous waste recovery, and the specifics of importing waste that is no longer waste into Serbia from one of the countries of the European Union. Through an example of converting fly ash into a useful cementitious raw material, some difficulties that have been encountered so far in practice are illustrated. In the conclusion of this paper, certain measures were proposed to overcome the mentioned obstacles in the implementation of the circular economy through the encouragement of the recovery of industrial waste.

AB  - In this study, a novel porous carbonaceous material, which has been synthesized from almond pits as precursors, has been characterized for the purpose of application as electrodes in electrochemical sensors. The powdery sample of activated carbonized almond pits was analyzed by X-ray diffraction (XRD) and Diffuse Reflectance Infrared Fourier Spectroscopy (DRIFT). Besides, the electrochemical properties of the sample were investigated in a three-electrode system using a CHI potentiostat. Obtained XRD diffractogram confirmed the amorphous phase of the sample, while DRIFT showed the presence of different functional groups. According to the results, synthesized carbonaceous material was found to possess great potential as a low-cost and eco-friendly material for electrochemical applications.

AB  - Nanopowders of CeO2 as a major component and different rare earth oxides added as dopants were synthesized using the modified glycine-nitrate procedure (MGNP) for the purpose of fabrication of electrolytes for IT-SOFC. Synthesized nanopowder was characterized by XRPD and Raman spectroscopy. According to results, single phase solid solution of fluorite structure were evidenced. Produced powder was then subjected to sintering at 1550 ºC for 2 h in air. By SEM analysis, highly ordered microstructure of sintered sample was verified, while EDS method revealed that the sintered sample have chemical composition very similar to a nominal one. Afterwards, the ionic conductivity of the sintered sample was measured by EIS method. The highest value was obtained at 700 ºC, amounting to 1.92×10-1 Ω-1 cm-1 .

AB  - In the present paper, possible application of novel ceramic adhesives with implementation of waste sludge for bonding of heating devices constructions was studied. For a comparison, five different samples with increasing waste addition percentage were prepared and their performance as heat-resistant adhesives were evaluated in terms of chemical and thermostability as well as ecological safety. Based on ICP-OES analysis it was observed that only sample GC20 is not ecologically-safe due to high level of Cu+ concentration. By withstanding thermal treatment in the range of 200-800˚C for over 100h, all adhesive samples showed satisfactory thermostability. This research confirms the great potential of the studied materials for application as uncostly and eco-friendly adhesives for industrial purpose.

AB  - Because of their widespread use as reagents in the flotation processing of sulphide ores, xanthates are largely found in tailings as residues. Regrettably, it is known that xanthates are not stable compounds and their decomposition generates carbon disulfide (CS2), a substance that is considered toxic. In this study, the chemical stability of xanthate was evaluated by UV/Vis spectroscopy, as a function of pH and time. The zero charge point of modified waste slag was also determined. The obtained results showed that the lowest degree of xanthate degradation is for the pH=10 and was 24.72%. For different concentrations of the KNO3 (0.1, 0.01, and 0.001 mol/dm3 ) the point of zero charge of the modified waste slag was 7.28, respectively

AB  - 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. © 2023 by the authors.

AB  - This scientific study investigated the use of activated carbon obtained from black alder cone-like flowers for the adsorption of cyanobacteria cells and cyanotoxins from raw water collected from Aleksandrovac Lake. The material was prepared by carbonization and activation, and the water sample was analysed for microcystin and cylindrospermopsin using LC-MS. The results showed that the lake had a high level of Cyanobacteria, making it unsafe for recreational activities. After treatment with the activated carbon, the removal efficiency was 99,8 %, and with no cyanotoxins remaining. The dominant cyanobacteria species was Raphidiopsis raciborskii, which is a producer of cylindrospermopsin. The study demonstrated the potential of activated carbon for removing harmful cyanobacteria and cyanotoxins from water sources.

AB  - Adsorption is one of the well-known methods in the removal of various pollutants from water bodies. The activated carbon material has great potential in water purification as an adsorbent. In process of adsorption various pollutants from water, such as different type of pathogens and toxins that can be potential risk for human health, can be effectively removed by activated carbon. The aim of this study is detail characterization of newly synthesized activated carbon materials from biowaste. Dried date palm leaf stalk (Phoenix dactylifera L.) and black alder cone-like flowers (Alnus glutinosa L.) have been chosen as bio-waste precursors. The activated carbon materials were firstly carbonized in atmosphere of N2 and then activated in atmosphere of CO2. Both processes are performed at 750 °C during 1 h. The yields of materials were 36.5 % and 24.7 % made of datepalm leaf stalk (P_AC) and black alder cone-like (A_AC) flowers, respectively. The commercial activated carbon has been characterized in order to compare with synthesized materials. For structural and chemical properties of materials was characterized in detail by: X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), low temperature N2 physisorption and Field emission scanning electron microscopy (FESEM). According to those results, materials obtained from date palm leaf stalk and black alder fruits show that newly synthesized materials have properties of an adsorbent with good potential for usage in water purification from different types of pollutants.

AB  - In order to avoid environmental issues considering disposal of great volumes of waste generated from the mining industry processes there is a tendency among researchers to find potential use of these harmful by-products. Waste slag is one such waste product since the content of different undesirable elements like cadmium, arsenic, zinc and other heavy metals may be at a level that can potentially endanger the environment and cause public health issues. On the other hand, tailings generated in the flotation facilities are also considered to be environmentally harmful because of different residual organic reagents that are applied in the process. As it is well-known, xanthates are the most widely used reagents in flotation processing of the sulfide ores, and, therefore largely present in tailings. Besides, xanthates are reported to pose toxicity and numerous negative impacts from the ecological point of view. That explains why it is of great importance to find efficient and low-cost routes for minimizing their remaining levels in tailings, therefore exposure to environment. In this study, xanthate absorption by using of the waste slag as adsorbent was investigated. For that purpose, three different starting concentrations of xanthates were selected, -20, 50 and 90 mg/l. The mass of the absorbent i.e. waste slag put into 50 ml of xanthate solution amounted to 0.01 g. Experiment was conducted on room temperature while pH value was set to be 10. The percentage of the total xanthates content absorbed was evaluated after the period of 24 h. Obtained results indicated that potential reuse of the waste slag for the removal of xanthates, may be justified and after 24 h, 98 %, 58 % and 62 % of the xanthates were adsorbed, respectively. However, further examination is needed in terms of better understanding of xanthate absorption mechanisms and improvement of waste slag absorption efficiency.

AB  - In the present paper, possible application of novel concept synthesis method of ceramic composite sealants (CCS) with implementation of alumosilicate-based waste material in intermediate temperature solid oxide fuel cells (IT-SOFC) was investigated. Besides two different basic variants of alumina matrix nanocomposites stabilized by rare earths and carbon materials (CCS-RE and CCS-C), for this purpose two additional sealant compositions with 5 wt.% addition of waste material (CCS-RE5 and CCS-C5) were designated for a comparative study. The aim of this research was to characterize the waste material, as well as the starting components used for developing ceramic composites through various characterization techniques. Analytical procedures for determining chemical composition with focus on heavy metal content in waste was performed in order to ensure the waste is ecologically acceptable to be used as an additive. Besides, the crystalline phase composition of the raw materials as well as of the sealant compositions was determined by X-ray diffraction (XRD) analysis. Finally, obtained results revealed that this research may provide the possible solution of forming a cost-effective, environmentally-friendly and high-efficient ceramic sealants for application in IT-SOFC by incorporating waste materials in its composition, without significant negative effects on its performance and main properties.

AB  - Nanosized multi-doped ceria with composition Ce0.8Nd0.0025Sm0.0025Gd0.005Dy0.095Y0.095O2-δ (CNSGDY) as perspective solid ionic conductor was obtained by modified glycine-nitrate procedure (MGNP) and room temperature self-propagating reaction (SPRT). The pressed pellets of both powders were sintered at 1550°C for 2 h in an air atmosphere. The obtained sintered samples were characterized by XRPD, Raman spectroscopy, FESEM, EDS and EIS methods. Despite a high temperature of sintering, XRPD and FESEM analyses of the samples confirmed appropriate dimensions of grains with fluorite structure. Overall concentration of introduced dopants (x = 0.2) in the structure of CeO2 after the sintering process was confirmed by EDS analysis. After sintering, Raman spectroscopy confirmed retention of the oxygen vacancies in the ceria lattice, which is in accordance with the improvement of ionic conductivity of solid ionic conductors. The highest value of total conductivity was obtained for the sintered MGNP sample at 700°C (4.22 × 10−2 S cm−1), with the corresponding activation energy of 0.26 eV.

AB  - In the present paper, possible application of novel concept synthesis method of glass-ceramic sealant with implementation of alumosilicate-based waste material in intermediate temperature solid oxide fuel cells (IT-SOFC) was investigated. Besides basic components for glass-ceramic sealant (sample GC0), for this purpose four additional sealant compositions with certain waste content, designated as GC1, GC2, GC3, GC4, were prepared for a comparative study. Waste was added in the basic sealant composition in such a way that certain percent of alumosilicate clay was substituted with alumosilicate-based waste material, with proper amount of water as a solvent. Waste share in compositions was 5, 10, 15 and 20% of total amout of alumosilicate clay as a replacement, respectively.A total of five different joint specimens were assembled by placing a sealant paste of 10mm thickness between two bricks to form brick/glass–ceramic/brick sandwich specimens appropriate for further heat treatments. Such formed ‘green’ joints were initially air-dried for 24h at room temperature, which was required for solvent to evaporate and cause initial bonding. Heating cycle in the period of four weeks was carried out in a chamber furnace. First day samples were heated to 200 ̊C for 2 h. Each day heating temperature was raised for 100 °C while dwelling time was prolonged for one hour, so by the end of the first week samples were heated to 600 °C for 6 hours. Next three weeks annealing of the samples was performed at 600 °C for 6 hours, 700 °C for 7 hours and 800 °C for 8 h, respectively, after what the thermal cycle was completed. The heating rate of the furnace at each heating step in the given joining process was 5 °C/min,while cooling was at natural speed. Mentioned firing temperatures were selected in accordance to common operating temperature range of IT-SOFC so as to simulate real working conditions. After the completion of the cycle, it was observed that all variants of the sealant withstood high temperatures without significant cracks or damage. Moreover, after detailed chemical, physical, mechanical and optical properties examination it was determined that compositions remained unaltered, which clearly indicates to their stability and reliability that is required for their application as sealants for IT-SOFC components. In addition, this research shows the possibility of forming a cost-effective, environmentally-friendly and high- efficient sealant for application in IT-SOFC by incorporating waste materials in its composition, without significant negative effects on its performance and main properties.

AB  - This paper presents the examination of potential application of slag, obtained from lignite combustion process in heating plant in Valjevo, Serbia, as a replacement for cement in mortars and concrete production. Waste slag was characterized with X-Ray Diffraction Analysis, Field Emission Scanning Electron Microscopy and Gamma spectrometric analysis, while its application possibility was investigated with testing Pozzolan activity Strength activity index, Activity index and Water requirement. The aim of this study is to determine under what conditions the slag could successfully replace cement in construction industry in certain percentages. Based on presented results it was concluded that, after mixing with silicate fume, waste slag can be used for the purpose mentioned. Optimal proportion of cement replacement is 20%-: 18% of slag and 2% of silica fume.

AB  - In presented paper influence of the modification on the point of zero charge of the waste slag generated by lignite combustion in heating plants and its properties for xanthates removal from aqueous solutions were investigated. The obtained results showed that the modification did have negligible effect on the point of zero charge and after modification the pHpzc changed from 6.92 to 6.90. The preliminary test of the xanthates removal from aqueous solutions showed that modification significantly increased removal efficiency, from 18.50 to 98.60 %.
