📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本ではEV普及に伴いバッテリー廃棄物処理が課題であり、本研究成果はセメント産業の脱炭素化と廃棄物削減の両立に寄与する可能性がある。ただし構造強度が低下するため非構造材への適用に限られる点に留意。
In the global GX context
Globally, rapid EV growth creates battery waste, and cement is a major CO2 source. This study provides a dual-benefit solution by upcycling battery waste into concrete while reducing embodied carbon, aligning with circular economy and low-carbon construction goals. Strength limitations restrict use to non-structural applications.

📄 Abstract（原文）
Lithium-ion batteries (LIBs) are essential for electric vehicles, consumer electronics, and grid storage, but their rapidly increasing demand is paralleled by growing waste volumes. Current disposal methods remain costly, complex, energy-intensive, and environmentally unsustainable. This pilot study investigates a scalable, low-impact disposal method by incorporating LIB waste into concrete, evaluating both the structural and environmental effects of LIB waste on concrete performance. Several cement–mortar cube specimens were cast and tested under compression using the cement–mortar mix with varying battery waste components, such as black mass and varied metals. All mortar mixes maintained an identical water-to-cement ratio. The compressive strength of the cubes was measured at 3, 7, 14, 21, and 28 days after casting and compared. The mix containing black mass exhibited a 35% reduction in compressive strength on day 28, whereas the mix containing varied metals showed a 55% reduction relative to the control mix without LIB waste. A case study was conducted to evaluate the combined structural and environmental performance of a concrete specimen incorporating LIB waste by estimating the embodied carbon (EC) for each mix and comparing the strength-to-net EC ratio. Selective incorporation of LIB waste into concrete provides a practical, low-carbon upcycling pathway, reducing both embodied carbon and landfill burden while enabling greener, non-structural construction materials. This sustainable approach simultaneously mitigates battery waste and lowers cement-related CO2 emissions, delivering usable concrete for non-structural and low-strength structural applications.
