home company zeolites products applications



Since a long time it is well-known that natural zeolites, due to their chemical-physical properties, can be managed in animal feeding. The addition of this mineral, also in very low dosage (1-2%), enhances very important functions, never recorded in other natural substances. ZEOFOOD, our high zeolite content product, accomplishes the following :

  • action as gastrointestinal pH buffer, since zeolites “catches” H+ ions in their structural channels;
  • inhibition of the development of harmful moulds, since zeolites absorb toxins as: mycotoxins (aflatoxins), enterotoxins, etc.;
  • regulation of the digestive process and prevention of intestinal pathologies as dysentery and gastroenteritis;
  • absorption of noxious substances as : ammonia, amine and generally bad smells for the benefit of animals and improvement of sanitary conditions of farms.
The above mentioned functions are naturally developed by ZEOFOOD, when it bound mycotoxins and has absorbed toxicant, being not soluble it passes harmlessly through gastroenteric part and it is expell through feces (not absorbed).


Recent experiments and several applications have proved that the use of natural zeolites in a modern conception of agriculture, according to the forthcoming European ecological regulations, is able to develop a role of primary importance as soil amendment and in cultural substrata having low cationic exchange capacity (C.E.C.) and scarce water retention. ZEOGREEN, our zeolite product for ecological agriculture, can be used in floriculture-horticulture and in garden hobby line for the following properties:

  • it promotes the cation exchange capacity by slow release of macroelements as potassium and ammoniacal nitrogen as well as several microelements with double advantage such as: decrease of fertilizer added to soil and the maintenance of its nutrition reserves;
  • increase of soil and/or other cultural substrata (peat and/or mould) water retention with reduction of the frequency of irrigation and water stress;
  • buffering of the burning effects of fertilizers;
  • loss decrease of the fundamental nutritive elements and reduction of polluting effects caused by nitrogen.
Finally, we remind that ZEOGREEN mixed with peat, mould and manure represents the best mineral support for the preparation of cultural substrata either for ornamental plants (planes, limes, citrons, maples, etc.) or indoor or garden plants.

Considering the importance of the properties of zeolites in environmental fields, our company in the last few years is trying to focuse its attention on the following experimental activities:
Chabazite can be used as a low cost natural mineral support for the abatement of Fe and Mn, as pre-treatment to successive processes such as exchange, oxidation and adsorption.
The removal of ammonium from tannery wastes by means of natural zeolites, can be achieved both by treatments on fixed zeolitic bed or by direct addition of zeolite to the waste. Since in this latter case the adsorption of ammonia (NH4+), requires considerable addition of zeolites, we are trying to solve the problem of huge mud production and/or to study a hypothesis of recycle of the same muds. Better results were achieved by column treatment which allows the regeneration of exhausted zeolitic material, with its subsequent recycle.
Many attempts have been carried out to use chabazite-phillipsite zeolites for the adsorption, in dissolved and colloidal form, of organic and nitrogen pollutant from wastewaters of small and medium productive settlement as houses, restaurants, hotels, etc, after primary treatments such as Imhoff tanks.
The surface porosity of zeolitite grains allows the settlement and the best reproduction of microorganisms (mineral bio-support) that develop the function of biological depuration through degradation of the pollutants.
The high affinity of chabazite towards some polluting cations promoted researches on the use of this zeolite in the treatment of Pb –bearing wastes. Tests carried out in presence of possible interfering cations such as Na, gave positive indications. Chabazite showed good affinity towards other heavy metals such as Cd and Cu.
Experimental tests proved that previously thermally activated chabazite, is able to selectively remove from CO2 – and inert gas-bearing mixtures undesired substances such as SO2 .
In order to prevent a break-down of the zeolite framework and the consequent reduction of its selectivity, it is necessary to use anhydrous gases.
