自動車分野でガラス繊維強化プラスチックに代わる低炭素材料として、レモン皮、オレンジ皮、クルミ殻、ピスタチオ殻を同一条件下でナノカーボンプレートに変換し、原料由来の構造・性能・環境影響の関係を比較した。ピスタチオ殻由来の炭素を1wt%添加したPP複合材料は引張強度を約34%向上させ、40wt%の亜麻繊維を含むMAPP相溶化複合材料では引張強度約52MPa、曲げ強度約75MPaを達成。LCAでは、ピスタチオ由来ハイブリッドがバージンPPでGWP 2.65kg CO2eq（30GF-PPの2.78kg CO2eqを下回る）、リサイクルPPで1.61kg CO2eq（42.1%削減）を示した。
English
This study converts lemon peel, orange peel, walnut shell, and pistachio shell into nano-carbon plates under identical conditions to compare feedstock-dependent structure, performance, and environmental impact. At 1 wt% loading, pistachio-derived carbon increased PP tensile strength by ~34% while preserving ductility; in MAPP-compatibilized composites with 40 wt% flax fiber, tensile and flexural strengths reached ~52 and 75 MPa, respectively. Cradle-to-gate LCA showed pistachio-derived hybrid with virgin PP achieved GWP of 2.65 kg CO2eq, slightly below the 30GF-PP benchmark (2.78 kg CO2eq), and recycled PP reduced GWP to 1.61 kg CO2eq (42.1% reduction). The work establishes a feedstock-sensitive upcycling strategy for circular composite design.

📄 Abstract（原文）
ABSTRACT As the automotive sector seeks lower‐carbon alternatives to glass fiber–reinforced polymers, biomass‐derived carbons are increasingly explored as sustainable reinforcements. However, biomass precursors are often treated as generic carbon sources, leaving the relationships among waste origin, carbon structure, composite performance, and environmental impact insufficiently understood. Here, lemon peel, orange peel, walnut shell, and pistachio shell were converted under identical thermal–chemical conditions into defect‐rich nano‐carbon plates, enabling a controlled comparison of precursor‐dependent structure–property–environmental relationships. Citrus‐derived materials exhibited more wrinkled and oxygen‐rich morphologies, whereas nutshell‐derived materials, particularly those from pistachio shell, showed more carbon‐rich surfaces and higher C/O ratios. At 1 wt.% loading, the nano‐carbon plates increased PP tensile strength by up to approximately 34% while largely preserving ductility. In MAPP‐compatibilized composites containing 40 wt.% flax fiber, the pistachio‐derived system achieved tensile and flexural strengths of approximately 52 and 75 MPa, respectively. Cradle‐to‐gate LCA revealed strong feedstock‐ and scale‐dependent differences. The pistachio‐derived hybrid showed a GWP of 2.65 kg CO 2 eq with virgin PP, slightly below the 30GF‐PP benchmark of 2.78 kg CO 2 eq, while recycled PP reduced the GWP to 1.61 kg CO 2 eq, corresponding to a 42.1% reduction. This study establishes a feedstock‐sensitive upcycling strategy for realistic circular composite design.
