An ecological habitat model of Earthgarden

1. Water recycling systems

The waste water is treated by microbes, then used for gardening.
A bio-geo-filter (BGF, or a Living Machine) is also installed. To make the water recycling process successful, we use biodegradable soap without synthetic suds. Rain water is harvested in a rain water tank.

2. Ecological construction materials and paints used for the house

Lumber from local plantation forests. Bees wax, fermented persimmon extract and other paints without pollutants are used inside, controlling the level of sickhouse chemicals.

3. Passive solar design for energy saving

The eaves are set at an angle blocking the summer sun yet allowing the winter sunshine to come in.
A solar collector on the roof heats up the water for showers and baths.

4. A wood-fired stove

Installed on the 1st floor, the stove's chimney goes up to the rooftop warming the two rooms on the second floor. The ashes from the stove are used in the garden.

5. Nutrient cycle

Almost all the kitchen scraps go into compost bins and worm bins for use in the vegetable garden. Our pet rabbit's manure helps fertilize our flower beds and trees.

6. Solar panels

Solar panels installed by the Kyoto Green Fund. The KGF is a non-profit organization promoting the use of solar energy and providing environmental education.

7. Methane digester tank

In the small tank connected to the family toilet, human wastes are turned into clean liquid fertilizer for use in the gardens.
