Soil forms the Earth and nurtures abundant resources.
The energy of the soil is the foundation of society.
NTT Group produces approximately a hundred thousand tons of industrial waste
such as telegraph poles and telecommunications equipment per year.
We believe it is our corporate responsibility not only to voluntarily dispose of waste in environmentally safe ways but also to maximize the reuse of waste through recycling.
This includes such measures as recycling nickel-cadmium batteries used in cordless telephones, and collecting telecommunications equipment which has been removed to be effectively utilized.
We intend to realize telecommunications in symbiosis with the Earth by stabilizing wastes at approximately 1990 year through the year 2000.
