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 considered a soil amendment that improves the soil condition by saving irrigation water and nutrients, improve soil natural aeration and production yield.

 

Porous Alpha type P310 (Granules) saves irrigation water and increases soil aeration

 

Porous Alpha type P03 (Powder) saves irrigation water and increases soil cohesion

 

Porous Alpha has no impact on soil salinity

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:

  1. Durable

  2. Simple

  3. Ecological

  4. Safe

A clean recycling technology is used to re-process used glass into foam glass product known as Porous Alpha

 

Porous Alpha is manufactured by recycling waste glass, removing all unwanted toxic elements in the waste glass which results in reducing waste, and being safe from any harmful substances.

 

Porous Alpha is considered a durable, non-biodegradable, and sustainable solution that can stay in the soil for up to 15 years

Porous Alpha is suitable for all climates, soil conditions, and water systems.
