This study is aimed to develop a beneficial use of disposed seashells. Sanriku region in Iwate prefecture has an issue of disposals of seashells. In this study, we mechanochemically ground seashells under dry or wet conditions. We used a planetary ball mill, a tumbling ball mill, and a converge mill as mechanochemical grinding machine. After the grinding, we examined the heavy metal absorbencies of the ground materials, and of the compounds with seashell-origin hydroxyapatite (HAP). As a result, followings were found out: 1) When seashell-origin hydroxyapatite was used, it showed adequate heavy metal absorbency (Cd, Pb). 2) When mechanochemically ground scallop seashells without HAP were used, it showed adequate heavy metal absorbency (Cd, Pb). 3) When the scallop seashells are ground for long time under dry condition (mechanochemical grinding), the material tends to be amorphous, and its heavy metal absorbency becomes greater.
