| Outline of Final Research Achievements |
This study aimed to utilize the hydrogen gas generated from municipal solid waste incineration bottom ash with water as an energy source. The influence of reaction temperature, liquid-solid ratio, and stirring speed on the hydrogen gas generation was clarified, and the effectiveness of grinding of bottom ash, addition of metal aluminum, and addition of sodium hydroxide on enhancement of hydrogen gas generation was examined. Moreover, the environmental and economic evaluation of hydrogen recovery from municipal solid waste incineration bottom ash was carried out.

| Academic Significance and Societal Importance of the Research Achievements |
都市ごみ清掃工場の灰ピットにおける爆発事故の原因物質としても知られる焼却残渣から発生する水素ガスに着目し、その水素ガスをエネルギー源として積極的に有効利用することを図る点に特色がある。我が国が脱化石燃料、脱原子力をなし遂げるには、代替エネルギー源の開発が急務であり、都市ごみからの水素ガス回収と再生可能エネルギーの有効利用の実用化を目指す本研究の意義は極めて大きい。
