| Outline of Final Research Achievements |
In the event of a large-scale disaster or an accident at a chemical plant, there are concerns about deterioration of the living environment and health hazards due to the accumulation of household odors and leakage of toxic substances. In addition, the global outbreak of the new coronavirus epidemic in 2019 has triggered a growing demand for disinfection methods that can be applied to a wide range of areas. As an environmental sanitation material for disasters, the applicant focused on Bioshell Calcium Oxide, calcium oxide fine powder calcined from scallop shells. It is a marine biomass resource with a low environmental impact during use as well as disposal that has been reported to have bactericidal activity and adsorption of organophosphorus pesticides. We have developed dispersions, agglomerated colloidal solutions, and ointments of Bioshell Calcium Oxide as versatile application forms and found that they had deodorizing, disinfecting, and infectious wound healing effects.

申請者が着目したマテリアルであるホタテ貝殻焼成酸化カルシウム微粉末はこれまでも殺菌効果や消臭効果が報告されており、食品加工の分野ですでに広く利用されている。しかし酸化カルシウムは水に難溶性のため、水溶液で使用する場合は噴射装置の目詰まりを引き起こし、使用用途が限られていた。本研究により、簡便な分散化法や凝集方法を確立し、一定の消臭効果、殺菌効果、有害物除去効果を示すことができた点が学術的意義として挙げられる。また、適切に処理されず悪臭が有害物質発生などの環境問題をもたらしてきた廃棄ホタテ貝殻を様々な形態に変化させて最も適した形態で環境衛生の向上につなげた点が社会的意義として挙げられる。
