Tokyo Manure Disposal--Collection trucks collecting manure barrels

In Tokyo, aside from the rural areas of the metropolis, the daily amount of excreta is enormous, averaging over 9,000 kiloliters. Of this amount, only 2.3 million, or 30 percent, is flushed, 150,000 is placed in digesters or manholes, and 1.91 million is piled into ships. The remaining 1.73 million is dumped by ship into the sea as fertilizer. The remaining 1.73 million is returned to farming villages as fertilizer, but the amount dumped into the ocean sometimes flows into beaches due to the currents, and the demand for rural returns is decreasing due to the increased production and use of chemical fertilizers in recent years.
