A class of naturally occurring volcanic minerals with distinctive physical and chemical properties includes zeolites. Because of its porous nature, this secure, organic, non-toxic, and affordable inorganic substance is often referred to as a “molecular sieve” and offers established economic advantages in a range of applications. There are more than 48 different types of natural zeolite minerals, all of which have similar molecular compositions and structural characteristics but differ in a variety of subtle and noticeable ways.

Zeolite is a magnet that can retain cations, including heavy metal, ammonia, low level radioactive elements, poisons, foul smells, petrochemicals, many other sorts of gases and a myriad of varied solutions. It is a highly porous sponge with a wide surface area that can absorb water up to 40% of its weight. The power of the mineral resides at its cage structure and at its Aluminium and Silicon concentration which gives the material a high cation exchange capacity.


There is a wide variety of zeolites to choose from. Zeolite manufacturers advocate for a “one size fits all” approach in solving issues and addressing all applications. However, a zeolite material mined in one deposit may be suited for removing radionuclides but not be suitable for agricultural use.

Zeolite deposits from Pangasinan, Philippines are mined and milled by LITHOS Manufacturing. The ore deposit is predominantly clinoptilolite and mordenite zeolite type. Some applications need unmodified zeolite types while other applications need a more complex type of adsorbents and such mineral zeolite is modified by heat treatment, pre-conditioning, gamma and plasma irradiation, chemical treatment and surface modification.  

  • We clean the invisible”

The Philippine natural zeolite has a big surface area of 200 sqm per gram of zeolite. The Philippine natural zeolite provides a surface where toxins unseen by the naked eye can be adsorbed and eradicated onto the zeolite honeycomb surface and gets trapped and unreactive to the environment. These invisible toxins pose health problems to humans, animals, and the environment. Noxious gases are ammonia, hydrogen sulphide, lead gas, nitrogen oxides, nitric oxide, sulphur oxides, carbon monoxide; Volatile organic compounds are benzene, toluene, xylene; heavy metals in water like lead, hexavalent chromium 6, cadmium, arsenic, aluminum; nutrients like phosphate, nitrate, pesticides, fertilizer; anions like fluoride, chlorine, sulphites, nitrites, these are ions that are adsorbed and attracted to the zeolite surface. One solution is to eliminate toxins with the use of natural and modified natural zeolites as an adsorbent, carrier, filters, and ion exchange materials in products and processes.
