The Tokyo Metropolitan Government has launched an innovative initiative to recover phosphorus from sewage sludge for use as a raw material for agricultural fertilizer.

In cooperation with the National Federation of Agricultural Cooperative Associations, or Zen-Noh, the Tokyo government aims to distribute nationwide fertilizers made from recovered phosphorus.
