Bio-Gas Applications
Biogas is obtained as a result of fermentation of native manure with subsequent purification from unwanted impurities. After purification, the content of methane in biofuel rises, therefore the quality of alternative fuel improves. Compared to other types of petroleum fuels, during engine operation the biogas produces the smallest amount of carbon dioxide and particulate matter and therefore has environmental implications.
Agricultural Applications
The repeated and heavy use of chemical fertilizers causes serious environmental hazards as only a fraction is actually absorbed by the soil. The extra fertilizer is washed off leading to high concentrations of potassium, nitrogen, and phosphorus in surface water bodies. These problems can be resolved using slow-release fertilizers. Zeolites promote the nutrient-retention capacity of the soils by improving the slower release of these elements for uptake by crops.
Increasing safety for the farmer and savings in energy are some other advantages of slow-release formulation (SRF) application. SRFs have been shown to supply the active ingredient of herbicides for a longer duration of efficacy at the required rate for weed control and reduce leaching potential and environmental pollution of herbicides by decreasing the total amount of the chemical required.
Zeolites have several positive effects on soil properties, such as increasing soil moisture, promoting hydraulic conductivity, and increasing yields in acidified soils; they are widely used as soil conditioners to improve soil physio-chemical properties. Zeolite is not acidic but is marginally alkaline, and its use with fertilizers can help buffer soil pH levels, thus reducing the need for lime application.
Steel and Iron Carbon Capture Applications
Steel is a cornerstone of the Indian economy and industry, however, its manufacturing process is highly energy intensive, it relies on conventional energy sources. As a consequence, it is the biggest source of CO2 emission and one of the most carbon-intensive industrial processes in the world. Capturing CO2 is then a necessary and inevitable option in order to mitigate the global carbon emission from the heavy industry sector.
Why Now?
The industry has a goal to reach net zero carbon emissions by 2050. Steel industry needs to identify the probable technologies and options to deal with a decarbonization trail, and understand different technology options, the pros-cons for better decisions. This review covers the impact of membrane based technology towards carbon neutrality and also portrays the future research possibilities towards this mission. Being a R&D company, NxTBrane is focused on the same issue and our target is to develop a membrane based technology to capture CO2 from different industrial sectors.
Water Filtration Systems
Zeolites can be incorporated into filtration systems to remove contaminants from industrial effluents or municipal wastewater, contributing to sustainable water management practices. Zeolites act as ion-exchange materials in water filtration systems, removing heavy metals and other impurities from water.
Petrochemical Industry Applications
Zeolites find extensive use in the petrochemical industry for catalyzing reactions such as cracking and isomerization. Their ability to facilitate specific chemical transformations has led to increased efficiency in the production of fuels and chemicals.
Environmental Applications
Zeolites play a pivotal role in addressing environmental challenges. Zeolite-based materials are known to be safe for human being and environment. Their ability to selectively adsorb heavy metals, ammonia, and other pollutants makes them effective agents for water and soil remediation. This is widely believed to be the most effective cheap and sustainable way in remediation of the contaminated environments.
Animal Husbandry
Zeolites dietary supplementation is an important step in the prevention of several diseases and in the advancement of animal health. Zeolite minerals help in performance-promoting properties in the diet of livestock husbandry.
- Removal of ammonia toxic effects produced by intestinal microbial activity;
- Reduction of the absorption of toxic products of intestinal microbial degradation, such as p-cresol;
- Elimination of mycotoxin growth inhibitory effects;
- Favorable effect on feed components hydrolysis over a wider range of pH, improved energy and protein retention;
- Reducing the passage rate of digesta through the intestines and more efficient use of nutrients.
FMCG
Zeolites, aluminosilicate minerals with a porous structure, find various applications in the Fast-Moving Consumer Goods (FMCG) industries. Here are some ways in which zeolites are utilized in FMCG:
Detergents and Cleaning Products:
- Ion Exchange: Zeolites are used as builders in laundry detergents. They exchange calcium and magnesium ions with sodium ions, softening water and enhancing the detergent\’s effectiveness.
- Absorption: Zeolites can absorb and hold water, improving the stability and flow properties of powdered detergents.
Odor Control
- Zeolites are employed in products like deodorant and cat litter to absorb and neutralize odors by trapping molecules within their porous structure.
Food and Beverages
- Desiccation: Zeolites can be used as desiccants in packaging to control moisture and extend the shelf life of food products.
- Selective Adsorption: Zeolites are used in the removal of unwanted substances or impurities from food and beverages, enhancing product quality and stability.
Oil Absorption
- Zeolites are used in products such as oil-absorbent pads or wipes for cleaning up spills in the kitchen or other areas.
Personal Care Products
- Zeolites are utilized in skincare products for their ability to absorb excess oils and toxins from the skin, contributing to the formulation of facial masks, cleansers, and exfoliants.
Air Purification
- Zeolites can be incorporated into air fresheners and purifiers to absorb and neutralize odors, making them common components in various household products.
Flavor and Aroma Retention
- In the food and beverage industry, zeolites may be used to help retain flavors and aromas, enhancing the overall sensory experience of products.
Catalysis in Food Processing
- Zeolites are employed as catalysts in certain food processing reactions, facilitating the production of specific food additives or flavors.
