本研究は、石灰製造における間接加熱炭酸カルシウムルーピング（IHCaL）CO2回収技術の初の包括的LCAを実施。5シナリオを評価し、IHCaLにより温暖化影響を80%以上削減可能と示した。SRF燃料では正味負の温暖化影響を達成。一方、褐炭利用では生態毒性や富栄養化が増加。燃料選択と上流工程の最適化が重要。
English
This study provides the first comprehensive LCA of indirectly heated calcium carbonate looping (IHCaL) for lime production, evaluating five scenarios. IHCaL reduces global warming impact by over 80%, with SRF-fueled systems achieving net-negative emissions. However, lignite-fueled scenarios increase ecotoxicity and eutrophication. Fuel choice and upstream optimization are critical.

📄 Abstract（原文）
Reducing process CO₂ emissions from lime production is essential for decarbonising one of the most carbon‑intensive industries. This study provides the first comprehensive life cycle assessment (LCA) of indirectly heated calcium carbonate looping (IHCaL) applied to lime plants, evaluating five scenarios: a reference plant, two tail‑end IHCaL configurations, and two fully integrated IHCaL configurations, each fuelled by lignite or solid recovered fuel (SRF). Using ReCiPe 2016 midpoint and endpoint methods and a functional unit of 1 kg of lime, environmental impacts were quantified across 18 categories and assessed using Monte Carlo uncertainty analysis (10,000 iterations). All IHCaL scenarios substantially reduce global warming impact relative to the reference case, with reductions exceeding 80%. SRF‑fuelled systems achieve net‑negative mean global warming impact due to avoided landfill burdens, and tail-end configurations further benefited from electricity export. However, lignite‑fuelled IHCaL scenarios increase freshwater and marine ecotoxicity, freshwater eutrophication, and human carcinogenic toxicity, driven mainly by upstream lignite mining. SRF‑fuelled scenarios avoid these burdens but have higher mineral and fossil resource scarcity impacts related to natural gas use in SRF processing. IHCaL offers a strong route to decarbonisation of lime production, provided fuel supply chains are carefully managed. The findings show SRF as the environmentally preferred fuel and underscore the importance of upstream process optimisation and region‑specific electricity modelling.
