Abstract
In order to depict the complex regional waste biomass flows at a glance and to account emissions from the regional system, we collected data on flows, compiled those in the database in the Kochi Prefecture and we designed the PIOT for data analysis. Specific features of our PIOT are; the household, the landfill and the deposit and stock were included in the intermediate demand, and energy consumption and production were arranged in the margin of the table. Preliminary PIOT in wet weight basis was presented.
