Outline of Final Research Achievements

In this research, we completed the following: A detailed characterization of MSWI fly ash from three incineration plants in Japan was performed. Several fishbone species and their hydroxyapatite contents were analyzed in detail. We conducted new sets of batch and column experiments under different analytical conditions to evaluate the effects of fishbone species on the leachability of heavy metals in fly ash. We generated Simulated leachates by leaching heavy metals from fly ash and stabilizing them using fish bone hydroxyapatite. Heavy metals were successfully stabilized in fly ash in the order of 80 to 100 % for Pb and Zn. We also performed the sequential analysis on the use of three stabilizing agents (zeolite, fishbone, and rice husk ash). The achievements were presented in three international conferences in China, Turkey, and Tunisia, two of them received best paper awards. One article was published at Waste Management journal (August 2022), and one more article is under review.

Academic Significance and Societal Importance of the Research Achievements

この研究は、フィッシュボーンが FA の重金属、特に Pb と Zn を安定化できることを示しました。 この手法では、10% の廃棄フィッシュボーンを FA に追加することにより、28 日間の沈降期間後に 86% 以上の鉛を安定化できました。 Zn の安定化は、より長い沈降期間 (28 日) で効率的でした。 この技術は、廃棄魚の骨の処理量を減らし、リサイクルを促進するのにも役立ちます。 さらに、フィッシュボーンと FA の最終的な混合量は、セメント化 FA の量よりも少なくなる可能性があります。 したがって、この手法は、比較的低コストで環境に優しく、持続可能な手法として期待されています。
