“…The synthesized zeolites have low solubility in water (0.89%–3.23%) and in citric acid (14.22%–18.57%). Considering the average release rate of the nutrient, compared to data of average absorption of K by different crops, zeolites have great potential to supply it for longer periods of time for direct application via soil (Estevam et al., 2021).…”

“…Studies have verified that zeolites produced using low‐cost precursors (residues), such as coal fly ash, rice husk ash and sugarcane ash, exhibited potential as a controlled‐release fertilizer (Bonetti et al., 2021; Estevam et al., 2021; Hermassi et al., 2020; Inácio, 2016). Mallapur and Oubagaranadin (2017) presented a complete review of zeolite synthesis by using different types of residues.…”

Zeolites have been widely applied as catalysts, wastewater treatment agents, gas adsorbents and fertilizers, among others. However, the use of natural zeolites or those synthesized from oversaturated commercial solutions are more explored commercially than the zeolites synthesized from residues. Therefore, the aim of this review is to highlight the importance of zeolites synthesized from agro‐industrial residues and their use in agriculture. This review has been divided into three different sections, that is, zeolites, agriculture applications, synthesis of zeolites from residues and their application in plant growth. In the first section, the definition, types and the critical properties of zeolites are explained. The second section gives a brief review of the application of zeolites in agriculture. Finally, the synthesis of zeolites from residues, such as coal ash, rice husk ash and sugarcane ash, with special attention to renewable sources is presented. The optimization of the synthesis of zeolites from residues with the incorporation of specific nutrients necessary for the cultivation of soybeans, corn and sugarcane (considered the most significant crops in Brazilian agriculture in terms of the planted area) can significantly contribute to the concept of circular economy at the industries and the fulfilment of sustainable development objectives, especially, the number 12 (SDO—12—Responsible consumption and production).

“…Moreover, a cost-effective method of FA utilization in producing a zeolitic product with a well-structured framework capable of efficiently retaining K ions was proposed. This product, called MER zeolite, exhibits improved performance in releasing K nutrients, thus minimizing nutrient wastage and reducing the risk of environmental pollution [159].…”

The synthesis and utilization of zeolites derived from fly ash (FA) gained significant attention years ago due to their potential to address environmental challenges and promote sustainable practices subscribing to the circular economy concept. This paper highlights the recent findings regarding the synthesis and utilization of zeolites derived from FA. It begins with a discussion about the recent challenges regarding industrial waste management and statistics regarding its availability on the global market with a special insight into the situation in Poland. The characteristics of FA obtained from various fuels were presented and the main differences were highlighted. Then, different methods used for the synthesis of zeolites from FA were discussed in small and pilot scales taking into consideration the main challenges and problems. The analytical methods used in porous materials synthesis verification and properties determination were described. The sorption properties of FA-derived zeolites were presented and discussed. Finally, the paper emphasizes the potential applications of fly ash-derived zeolites in different fields. Their importance as sustainable alternatives to conventional materials in industry, construction, agriculture, power, medicine, and other industrial sectors was analyzed.

“…The FA are composed of small particles, presenting an average particle size between 3 to 34.57 µm, and are mainly composed of SiO 2 , Al 2 O 3 , Fe 2 O 3 , TiO 2 , CaO, and MgO [8][9][10][11][12][13]. The disposal of FA may be related to economic and environmental problems around the world, and thus researchers have been developing studies regarding its reuse, such as the synthesis of zeolite [12,14,15], development of a catalyst used in the decomposition of NO and NH 3 [16], recovery of gallium and vanadium [17], Zn 2+ , Pb 2+ , As (V), hexavalent chromium and dye…”

This work aims to prepare and characterize the unburned carbon obtained from gasification residues and evaluate its application as an adsorbent for the removal of textile dye contaminants. The results of physical and chemical properties showed a specific mass of 2.05 g/cm3, surface area of 23.983 g/cm2, and diameter and pore volume of 0.844 nm and 2.262 cm3/g, respectively. These properties, along with the point of zero charge and chemical bonds present on the surface, favored the adsorption of cationic dyes. The adsorption results showed great potential for the removal of methylene blue, crystal violet, and basic fuchsin if compared with bromocresol green, and indigo carmine. The maximum removal values obtained for methylene blue were up to 99% and the kinetic adsorption was faster at the beginning of the process, reaching the equilibrium in less than 5 min. The results obtained through the adsorption isotherms showed a maximum adsorption capacity of 333.33 and 476.19 mg/g, at the temperature of 291 and 328 K, respectively. The satisfactory results showed that the use of unburned carbon is a cost-effective and eco-friendly alternative to reusing the residue from gasification and also contributes to the decontamination of watercourses.
