With the soil mixing method

We mix kitchen garbage and soil and break down kitchen garbage by power of microorganism in soil and are method to turn soil into thing which nutrition is rich in.


  • We do not take place.
    If there is space for four planters even if there is not garden, there is.
  • Anyone can do it by simple method.
    Special work and tool, medicine are not necessary.
  • We can use made soil for gardening.
  • We are not in trouble in use of made soil.
    As made soil is usable in kitchen garbage and soil to mix again, soil increases and may not be in trouble.
  • Eco-friendly.
    We can recycle easily at home without taking out kitchen garbage as garbage.

We prepare

  • Kitchen garbage
  • SAT
  • Planter


As the soil mixing method breaks down kitchen garbage by power of microorganism, it is important to fix environment that is easy to act of microorganism. Specifically, we push forward work while being careful about adjustment of fluid volume, supply of oxygen.

1.We mix chopped kitchen garbage and soil small.

Kitchen garbage is small, and the resolution is early. (from 2 3cm indication)

  • Afterwards, sometimes stir (once a week indication); stirred frequently, and the resolution is earlier.
    Point: Supply of oxygen
  • When it dries too much when we stirred, we add water and when it is juicy, we put dry soil and mix.
    Point: Adjustment of fluid volume

5.We continue in other planters in the same way.

When four planters become full, the first planter is completed.

Analysis of soil

We ask Specialized Agencies and analyze thing which puts kitchen garbage into commercially available black soil for 30 days, and was completed. As a result, completed soil became clear with good soil to raise flower and vegetables. For more details, please refer to Regional Promotion Division Resources Reuse Promotion. (December, 2009 conduct)
