本研究は、石灰石廃棄物処理と二酸化炭素回収・利用（CCU）技術を統合した建築材料生産の脱炭素化アプローチを提案する。物質・炭素フローのバランスモデリングにより、廃棄物の85-95%を二次経済循環に組み込み、CO2排出量を30-40%削減できることを示した。最終埋立量は従来比6-10分の1に減少し、循環経済の原則に合致する。
English
This study proposes an integrated approach combining limestone waste processing and Carbon Capture and Utilization (CCU) for decarbonizing building materials production. Material and carbon flow balance modeling shows that 85-95% of waste can be recirculated and CO2 emissions reduced by 30-40% with 60% CCU capture efficiency. Landfill volume decreases 6-10 times compared to fragmented management, aligning with circular economy principles.

📄 Abstract（原文）
Carbonate raw material processing generates significant limestone screenings and CO₂ emissions from the chemical decarbonization reaction (CaCO₃ → CaO + CO₂). Fragmented environmental measures fail to systematically reduce the overall environmental burden. This study develops an integrated approach to managing mineral and carbon flows. The methodology includes analysis of scientific publications, examination of technological schemes, balance modeling of material and carbon flows, and conceptual assessment of integrating Carbon Capture and Utilization (CCU) technologies into wet flue gas cleaning systems. Implementation of the integrated scheme enables the involvement of 85–95% of limestone screenings in secondary economic circulation. Process decarbonization calculations show CO₂ emissions reach approximately 0.418 t per ton of processed raw material (95% CaCO₃ content). CCU implementation with 60% capture efficiency reduces total CO₂ emissions by 30–40%. Comparative analysis reveals a synergistic environmental effect through comprehensive management of solid, particulate, and gaseous flows. Landfill volumes decrease by 6–10 times compared to fragmented management. The proposed concept aligns with circular economy principles and serves as a methodological basis for modernizing carbonate processing enterprises.
