This is a natural volcanic material with a high and selective cationic exchange capacity. Zeolite total content: approx. 58% (Chabazite 45÷53%; Phyllipsite 3÷6%; Analcime 3÷5%).

Materials of organic origin, ZEOLITES are distinguished through their elevated and selective property of cationic exchange and have the capacity to neutralise, by keeping them internally in their own structure, leached elements such as ammonium, heavy metals and organic molecules. In addition to that, they are absorbing bad smelling gases like ammonia, hydrogen sulphide and the mercaptans – they are reducing also the emission of odours produced by biomass conversions exhausting from the cots or other similar buildings.

Furthermore, Zeolites can be of great advantage in the agricultural field, in any kind of culture, as amendment to grounds or in addition to cultivation grounds and substrates, improving the physical properties of the soil and the exploitation of the fertilizers. As result, the required quantities of synthesized fertilizers, irrigation water and finally the rate of pollution of the hydrological system; both superficial and deep.

The range of dried products is being used as absorbent and filter for industrial oils, general surface cleaning, slight abrasive and component for premixed products in the building industry (light aggregates for mortar and cement conglomerates).


  • Neutralizing harmful elements, ammonium, heavy metals and organic molecules.
  • Absorbing odorous gases, ammonia, hydrogen sulphide, mercaptans.
  • Improving the exploitation of fertilizers thereby reducing the quantity to be used.
  • The range of dried products is used to absorb and filter industrial oils, for general cleaning of surfaces, as a soft abrasive and as a component in pre-mixed materials in the building industry.
  • To be used in addition to cultivation substrates or for soil conditioning.

Fields of application

Wastewater purification - phyto-purification

The concentration of NH4 in the waste water produced by biological activities, by the disposal of solid urban waste, by industrial activities and the content of pollutants in industrial waste water are drastically reduced by means of dynamic or static treatments with zeolites which have appropriate selective properties in relation to the polluting ion.


By applying the zeolites to agricultural land and to substrates used for garden and flower cultivations in greenhouses results in a marked qualitative and quantitative improvement in production, a reduced use of synthetic fertilizers, irrigation water and pollution of the surface and deep hydrological system.
