How much do you know about invisible hazardous chemicals? The problem of contaminants in soils and water has become aggravated. We secure our safety in presen t and the future from the risk of various hazardous chemicals.

Spray Maite Kantan over the soil and mix. Rainwater or water sray will initiate the process. Use approximately one (1) kg of Maite Kantan per are. Depending on the soil quality and residual concentration, the amount needed for enough absorption varies.


Since pellet type is in granular form, it has broad utility and can be used by itself or by mixing with fertilizer. If sprayed and cultivated during the agricultural off-season, it decreases the injuries by continuous cropping and excessive pesticide.

Environmental improvement application is a safety-conscious product and made from activated carbon and specialty cellulose which is used for foods, thus it can safely absorb pesticide residue. Degradation of environmental pollutants by microorganisms in the soil is achieved.

255 pesticides refer to Positive List System for fungicide(Isop rothiolane etc), incecticide(Phorate etc), herbicide (Molinate etc) in simultaneous analysis items. It also adsorb dioxins and drins.
While water contamination is becoming more serious, obtaining good quality water is important globally these day. Persistent organic pollutants (POPs), industrial wastes and pesticide are spread into the wide range of water source such as groundwater, wells, lakes and rivers and cause possible adverse effects. Therefore, easy, highly effective and safe technique for water purification has been strongly demanded. We designed the tablet type from safe and highly efficient powdered activated carbon and investigated the adsorption effect as a new water purification technique.

Ultra fine powdered activated carbon is available in different shapes and sizes depending on the intended use.

Used powdered activated carbon have not only high absorption ability for organochemicals but is highly safe and environmentally-friendly product, not containing heavy metal nor arcenic.




Without stirring water, it is able to remove color by adsorbing pigments.


After adding tablets to sample water containing 255 different types of fungicide, insecticide and herbicide, 80 to 100% of pesticides are adsorbed and the water is purified in 30 minutes.


After adding, adsorption capacity of powdered activated carbon tablet is maintained for more than 6 months.

Zeolite is one of the natural minerals that upon heating or decompression, it produces large amount of steam from water that has been adsorbed by the material. Based on this, it is named ZEOLITE "boiling stone", from the Greek, zeo meaning "boil" and lithos meaning "stone".
There are naturally produced "natural zeolites" and chemically synthesized "synthetic zeolites".
"Kantan Zeolite" is a new and unprecedented type of zeolite.

Kantan Zeolite has two properties: porous structure that can ad sorb substances (Adsorption Capacity) and exchanging Na+ that are already present on negative charges with other cations such as heavy metals (Cation Exchange Capacity).


ĤMeasurement of cation exchange capacity is based on Soil Nutrient Analysis 3.2.1 (ammonium acetatemethod by Schollenberger)
Kantan Zeolite has high retention power of water and fertilizer thus reducing losss of nutrients in soil and improving plant growth. It is useful for soil amendment in agriculture and greening. It also effective for greening the dry land.

Greening Test in Catar
(Salt damage measure)
Cation exchange capacity that is one of Zeolite properties enables heavy metals to be adsorbed.
Filtration test using column test was conducted.
Solution mixed with heavy metal was adjusted to specific concent ration and measured the concentration after 30, 60, 100, 200, 300 minutes on contact with the filter (Kantan Zeolite Ca Type Coated Granular).
