What is Zeolite

What Is Natural
Clinoptilolite Zeolite

Zeolite is a natural aluminosilicate mineral formed when volcanic ash crystallizes in marine basins over millions of years. Its internal, ordered microporous structure and negatively charged framework give it the ability to selectively exchange and adsorb specific cations.

KMIZEOLITE's clinoptilolite has a purity of 97% and is the most widely used zeolite species in industrial applications worldwide. Molecular formula Na₆[Al₆Si₃₀O₇₂]·24H₂O, CAS 1318-02-1.

Application Value Proven by Data

44%
Ammonia Reduction

Adding 38% zeolite by weight to poultry litter reduced ammonia loss by 44% (Karamanlis study)

70%
Strawberry Yield Increase

Study results show a 70% increase in strawberry yield and a 70% reduction in nitrogen leaching with zeolite soil treatment

30%
Cement Replacement

Can replace up to 30% of Portland cement. Reduces carbon footprint while improving durability (ASTM C618)

35%+
Asphalt Fuel Savings

Adding zeolite to warm-mix asphalt cuts burner fuel consumption by more than 35%

Parsley Biomass

With zeolite treatment, parsley biomass rose from 487g/m to 1,500g/m (roughly a 3-fold increase)
