Abstract
The structure by which the outflow corruption to river which has brought about organic matter inflow to which population, processing of an organic matter superfluous in the river basin region area of the big city to which concentration of industry went, consumption, and abandonment exceed the environmental capacity in the river basin region area, and the corruption load of point and non-point in the ocean space carried out are finally discharged by the exclusive ocean space of a mouth of a river through a river has caused the present serious aggravation as a result.
In this paper, the generating distribution of the organic waste in a city region was calculated in Saitama Prefecture and the Arakawa river basin region area over Tokyo using the calculation system utilizing GIS. Evaluation results identify about the application possibility of small-scale biomass energy use among the circulation use systems of an organic matter on it.
