Outline of Annual Research Achievements

In order to develop a novel method for recovery of elements that will increase Japan's self-sufficiency and reduce the need for metal imports, the key aim of this project is to synthesize stable porous monoliths from waste seaweed and rice straw. Therefore the first task was to source feedstocks of these wastes. One kilogram (dry weight) of each biomass was likely to be sufficient for lab scale testing. Once received laboratory-scale, investigations into the production of porous materials using sustainable and salable procedures should begin. The idea was to keep production simple and low cost with a maximum of three to five steps from the initial biomass feedstock to final material.

Current Status of Research Progress

3: Progress in research has been slightly delayed.

Reason

研究環境が分担者の希望に沿わなかったため研究が当初の計画どおりに進まなかった。

Strategy for Future Research Activity

今後は研究代表者を交替し、分担者の希望に沿った実験設備や研究環境も有する部署に移動し研究を遂行する。
