“…The XRD pattern of the natural zeolite (ZA) displayed prominent peaks at 2-theta angles of 9.9°, 11.14°, 13.08°, 17.42°, 19.02°, 22.46°, 26.1°, 28.1°, 30.12°, 31.04°, 47-1870 reference chart, suggesting that Tanggamus natural zeolite predominantly consists of clinoptilolite. This type of zeolite has also been widely reported to constitute the majority of natural zeolite from various geological sources (Akgül and Karabakan, 2011;Wang et al, 2022;Karadag et al, 2006;Vassileva and Voikova, 2009;Kurniawan et al, 2022).…”

This research explores the potential of locally sourced natural zeolite from the Tanggamus District, Indonesia, for the removal of ammonium from shrimp pond wastewater. The study utilizes a comprehensive approach involving desilication modification, batch adsorption experiments, and field-scale application. The zeolite, predominantly composed of clinoptilolite, undergoes calcination at varying temperatures, with 200°C proving to be optimal for enhancing ammonium adsorption capacity. The study also highlights the efficient use of zeolite at a lower dosage of 5 g/L, yielding high removal efficiency. The real-world effectiveness of this method was confirmed by field experiments, where the application of calcined zeolite resulted in lower ammonium concentrations in shrimp ponds. The results demonstrate that the application method, specifically direct spreading in the ponds, affects adsorption performance. These findings underscore the potential of using Tanggamus Natural Zeolite as a cost-effective and eco-friendly solution for ammonium control in shrimp pond wastewater. This work paves the way for future research focusing on the long-term application effects and zeolite regeneration methods to further improve the economic and environmental efficiency of this approach.

“…It is worth mentioning that one of the most produced and potential byproducts of transesterification is glycerol. Alkaline-treated CLI showed activity in the catalytic acetalization of glycerol to fuel additives, such as Solketal [86]. Catalytic tests performed in a glass tube reactor at 50 • C for 90 min indicated a significant increase in glycerol conversion (90.4%) compared to parent CLI (3.5%).…”

Many efforts have been devoted to produce green materials and technology to prevent and minimize the adverse effects on the environment and human health caused primarily by population growth and industrial progress. Over the past years, the use of zeolites has attracted considerable attention as both an economically and environmentally friendly option. Zeolites are crystalline, hydrated aluminosilicates with an open-framework structure. Unique structural features make them very useful ion-changers, adsorbents and catalysts. The catalytic use of zeolites has expanded from traditional use in the petrochemical industry and refineries to use in the catalytic degradation of various environmental pollutants and the synthesis of fine chemicals. In recent times, progress on the use of zeolites has been achieved in biomass conversion to fuels and valuable industrial bio-based chemicals. This review highlights the recent advances in the catalytic application of clinoptilolite (CLI), the most abundant and explored natural zeolite. The main goal of the review is to give the current state of CLI applications and insights into CLI catalytic performance, which opens possibilities for a variety of applications.
