Theses about Zeolite

In modern agriculture, the need for sustainable and cost-effective solutions for crop fertilisation is more pressing than ever. With the skyrocketing cost of inorganic fertilisers and their environmental impact, scientists are increasingly turning to alternative solutions. A recent Greek study sheds light on the combination of sewage sludge with natural zeolite, revealing impressive results for barley production and soil health. What is sludge and why should we use it? Sewage sludge (also known as biosolids) is an organic residue resulting from the treatment of urban wastewater. It contains valuable nutrients such as nitrogen and phosphorus, as well as organic matter ... Read more

The need for renewable energy sources is becoming increasingly urgent. Biogas is a solution that utilises organic waste to produce energy. To be used efficiently, biogas must be upgraded to biomethane. According to this study, one of the most modern upgrading methods is Pressure Swing Adsorption (PSA) technology, in which zeolites play a significant role. What is biogas and why does it need to be upgraded? Biogas is produced through the anaerobic digestion of organic materials, such as agricultural waste, livestock manure and urban sewage. Its main component is methane (CH4), but it also contains carbon dioxide (CO2) and other ... Read more

New strategies and commercial products must be developed to improve animal health and performance, based on their safety, efficacy and cost-effectiveness. The aim of this study is to summarize the beneficial effects of currently used alternatives to in-feed antibiotics, i.e. probiotics, prebiotics, organic acids, phytogenic compound sand zeolites on health and growth performance in farm animals (swine, poultry and ruminants)

Effects of Supplementation of Natural Zeolite on Intake, Digestion, Ruminal Fermentation, and Lactational Performance of Dairy Cows

Abstract Effective treatment of chronic illness resulting from the long-term buildup of heavymetals in the body, such as chelation therapy, presents numerous clinical challenges, includingundesirable side effects and unpredictable efficacy. Use of a naturally occurring zeolite, clinoptilolite, to remove these toxic substances may offer an efficacious and safe alternative to thetraditional approaches. This study was designed to evaluate the ability of activated clinoptilolitesuspended in water (ACS) to remove heavy metals from the body through urinary excretionwithout the undesirable removal of physiologically important electrolytes. The protocol utilizedtwo treatment groups, each consisting of eleven healthy men aged 36 to 70 years. Volunteerswere ... Read more

Abstract Unique and outstanding physical and chemical properties of zeolite materials make them extremely useful in a variety of applications including agronomy, ecology, manufacturing, and industrial processes. Recently, a more specific application of one naturally occurring zeolite material, clinoptilolite, has been widely studied in veterinary and human medicine. Due to a number of positive effects on health, including detoxification properties, the usage of clinoptilolite-based products in vivo has increased enormously. However, concerns have been raised in the public about the safety of clinoptilolite materials for in vivo applications. Here, we review the scientific literature on the health effects and safety in medical applications of ... Read more

Zeolite or urea-impregnated zeolite as slow-release ammonia or SRU agent was potential in decreasing ruminal ammonia, pH, acetate to propionate ratio, methane, and maintaining low plasma urea within its physiological range.

In the most recently published study by the University of Patras, the effectiveness of natural zeolite in removing ammonium ions from synthetic wastewater and from secondary whey was investigated. Subsequently, the use of this zeolite as a fertiliser in wheat cultivation was investigated, given that zeolite can release bound nitrogen into the soil.

A study by the University of Patras, which investigated the effectiveness of natural zeolite in removing ammonium ions from synthetic wastewater and from whey.

The efficiency of natural zeolite to remove ammonium from artificial wastewater (ammonium aqueous solutions) and to treat second cheese whey was examined, aiming to recover nitrogen nutrients that can be used for further applications, such as slow-release fertilizers. Sorption experiments were performed using artificial wastewater and zeolite of different granulometries (i.e., 0.71–1.0, 1.8–2.0, 2.0–2.8, 2.8–4.0, and 4.0–5.0 mm). The granulometry of the zeolite had no significant effect on its ability to absorb ammonium. Nevertheless, smaller particles (0.71–1.0 mm) exhibited quicker NH4+-N adsorption rates of up to 93.0% in the first 10 min. Zeolite as a Potential Medium for Ammonium Recovery ... Read more

Zeolite and its potential uses in agriculture C. Sangeetha* and P. Baskar1, Department of Agronomy, Tamil Nadu Agricultural University, Coimbatore – 641 003, India. Received: 10-09-2015 Accepted: 25-02-2016 DOI:10.18805/ar.v0iof.9627 ABSTRACT In many parts of the world food security is being affected due to declining quality and/or quantity of the soil resource base and climate change. In this context, farming with zeolites has drawn attention. Zeolites are natural aluminosilicates present in rocks different part of the world. Use of zeolite has gained a momentum in the recent past owing to multitude of benefits accured from them. Zeolites are useful in agriculture because of their ... Read more
