Scallop shells, which are a waste product in the seafood industry, are disposed more than 200,000 ton per year in Hokkaido, Japan. We report effective uses and simple application for discarded shells as a formaldehyde adsorbent. The adsorption performance of scallop shells to remove formaldehyde vapor is investigated. Planetary ball milling under dry conditions and subsequent water addition realize shells with a crystallite size (35-90 nm) and equivalent size of the specific surface area (41-191 nm) in the nanometer range. The comminution properties of the scallop shells, especially the grinding limit, are estimated via a semi-theoretical consideration for the grinding limit. Additionally, the adsorbed amount of gaseous formaldehyde using a self-designed adsorption line is estimated. The nanosized scallop shells exhibit an excellent adsorption performance rather than the feed shell, and the adsorbed amount is positively correlated with the specific surface area of the shell. Hence, scallop shells have potential to adsorb volatile organic compounds.

在日本北海道，扇贝壳是海产品工业中的废弃物，每年被处理20多万吨。我们报告了废弃贝壳作为甲醛吸附剂的有效用途和简单应用。研究了扇贝壳对甲醛气体的吸附性能。在干燥条件下的行星式球磨和随后的水添加实现了具有在纳米范围内的微晶尺寸（35-90 nm）和比表面积的等效尺寸（41-191 nm）的壳。通过对扇贝贝壳粉碎极限的半理论分析，估算了扇贝贝壳的粉碎特性，特别是其粉碎极限。此外，利用自行设计的吸附线估算了甲醛的吸附量。纳米级扇贝贝壳比饲料贝壳具有更好的吸附性能，吸附量与贝壳的比表面积呈正相关。因此，扇贝壳具有吸附挥发性有机化合物的潜力。
