本研究は、ポーランドの実験的ラムドアース建築を対象に、解体と再利用戦略を比較したライフサイクル評価を実施。手動解体と現場再利用が最も低炭素であることを示し、安定化土材料の回収・再利用に関する標準化された技術手順の欠如を指摘。設計段階でのマテリアルパスポートやBIMの活用を提唱。
English
This life-cycle assessment study compared demolition and reuse strategies for a rammed earth building in Poland, finding that manual deconstruction with on-site reuse yields the lowest carbon footprint. It highlights the lack of standard procedures for recovering stabilized earthen materials and emphasizes the importance of early design-phase planning with digital tools like material passports and BIM.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
ラムドアース工法は日本では一般的ではないが、循環経済の視点や建材のライフサイクル管理、解体時のGHG排出評価は、建設分野の脱炭素やSSBJ対応において参考になる可能性がある。
In the global GX context
Globally, this paper contributes to the growing literature on circular construction and life-cycle assessment of low-tech building methods. Its findings resonate with EU's circular economy action plan and the push for material passports, though the specific earth-building context limits direct transferability to mainstream construction.

📄 Abstract（原文）
This study aims to evaluate the potential of circular economy principles in earth-based construction using an experimental rammed earth building located in Pasłęk, Poland as a case study. The research focuses on end-of-life scenarios for earth materials, with particular emphasis on rammed earth, adobe, and compressed earth blocks stabilized with Portland cement. A scenario-based life-cycle assessment (LCA) was conducted to compare alternative demolition and reuse strategies, including manual and mechanical deconstruction, as well as on-site and off-site material reuse. Greenhouse gas emissions associated with demolition (Module C1) and transport (Module C2) were estimated for each scenario. The results indicate that manual deconstruction combined with local, on-site reuse leads to the lowest carbon footprint, whereas off-site reuse involving long-distance transport significantly increases greenhouse gas emissions. In addition, qualitative reuse pathways were identified for wood, glass, ceramics, and insulation materials. The study reveals a lack of standardized technical procedures for the recovery and reuse of stabilized earthen materials after demolition and highlights the importance of integrating end-of-life planning into the early design phase using digital tools such as material passports and BIM. The findings demonstrate that properly designed rammed earth systems can provide a viable low-tech solution for reducing construction waste and supporting circular material flows in the built environment.
