| Research Abstract |
In this research, we carried out surveys in Osaka Bay and several kinds of fundamental experiments to proof usefulness of environmental restoration for eutrophic sea area utilizing marine biomass, and developed some important technologies, such as conversion of seaweeds to value-added materials, large-scale cultivation of green macroalgae, mixed methane fermentation of marine and waste-food biomass, and so forth. We also performed both environmental and economic evaluations for plural scenarios of biomass collection and treatment systems based on the fundamental data obtained by the field surveys and experiments. The results suggested that the suitable scenario leads to good performances of environmental restoration and low carbon effect, but this concept basically involves some difficulties for practical use, e.g. small surplus of energy from marine biomass, limit of demand of residue as fertilizer.
