Agriculture
If Porous Alpha is mixed with soil, the water retention capacity of the soil is increased, because the pores of Porous Alpha catch and retain water which otherwise would infiltrate in the soil. Fertilizer is retained as well and soil aeration is also one of the key features.
Water Treatment
Porous Alpha can reduce the cost of treatment for discharged water with phosphorus.
Our company has patents on the Production methodology of adsorption agent of Phosphorus ion, Phosphorus acid fertilizer, and adsorption agent of phosphorus ion.
Porous Alpha can reduce the cost of fluorine water treatment. Our technology “Fluorine adsorption agent and fluorine-containing water treatment” is patented.
Air Treatment
Compared to the competing solution based on rock wool, we have advantages in durability & cost.
Microbes derived from manure, contained in Porous Alpha, digest gases in the interconnected pores.
Porous Alpha is compliant to Japanese soil environmental standard.Based on the result of leaching test, the utilization of Porous Alpha doesn‘t have any problem related to heavy metal and toxic product to use it as the soil including mixing with soil.
Key advantages:
-
Durable
-
Simple
-
Ecological
-
Safe
Under the Japanese regulation, Porous Alpha can be used safely as a soil conditioner for agriculture.
Result of leaching test based on the “Environmental regulation regarding the soil pollution”, 23 August 1991, Ministry of Environment, analyzed by Tottori Health Service Association.
Porous Alpha exists since 2005. Due to its origin, it could last for a long time. We believe that 25+ years without losing properties is possible
