本論文は、養殖・食品加工の副産物である二枚貝殻のリサイクルを通じた脱炭素化の可能性を検討する。貝殻から高純度炭酸カルシウム（CaCO3）を抽出し、カルシウムルーピング（CaL）によるCO2吸収材として利用する。MATSHELLプロジェクトの成果として、生物由来CaCO3が従来品に代替可能であり、高付加価値市場での需要が高まっているが、サプライチェーン統合や規制の複雑さなどの障壁が存在する。専門家インタビューに基づく分析により、産業共生モデルに沿った課題解決策を提示する。
English
This paper explores the potential of recycling bivalve shells, a by-product of aquaculture and food processing, for decarbonization. Shells provide a sustainable source of high-purity calcium carbonate (CaCO3) used in calcium looping (CaL) for CO2 capture, supporting circular economy principles. The MATSHELL project shows that biogenic precipitated CaCO3 offers a competitive alternative to conventional sources with rising market demand, but faces barriers in supply chain integration, regulatory complexity, and industrial adoption. Expert interviews identify actions to address challenges within industrial symbiosis models.

📄 Abstract（原文）
Recycling mussel shells offers environmental and industrial benefits. As a by-product of aquaculture and food processing, shells are often discarded, contributing to waste management challenges and costs. Recent studies highlight their potential as a sustainable source of high-purity calcium carbonate (CaCO3), which can be extracted through processes involving washing, grinding, and calcination. This valorization reduces waste volumes, lowers disposal expenses for producers and introduces low-cost raw material to the CaCO3 market. Notably, calcium derived from mussel shells can be utilized in emerging technologies such as calcium looping (CaL) for CO2 capture, where calcium oxide (CaO) acts as a regenerable sorbent. Using shell-derived calcium in such applications supports circular economy principles and enhances the environmental performance of carbon capture. The MATSHELL project explores the potential of recycling bivalve shells to produce biogenic CaCO3 and reuse for high-value applications. Findings show that biologically sourced precipitated CaCO3 offers a competitive alternative to conventional sources, with rising market demand in high-value sectors. However, key barriers exist, including supply chain integration, regulatory complexity, and limited industrial adoption. The results of our analysis, conducted by interviewing a panel of experts, identified potential actions to address the challenges in accordance with industrial symbiosis models. The potential of the developed model was enhanced by integrating appropriate activities to optimize its implementation.
