薬用植物廃棄物（MPW）はリグノセルロース系バイオマスを豊富に含み、再生可能エネルギー原料として有望である。本レビューは熱化学変換（トレファクション、熱分解、ガス化、水熱炭化）を整理し、バイオオイル30-55wt%、バイオ炭20-35wt%、コールドガス効率55-70%等の収率を示す。MPW由来バイオ炭は乾燥原料1トンあたり約2-3t CO₂-eqの炭素隔離に寄与し、土壌保水・養分保持を改善する。原料変動性や政策ギャップが課題だが、触媒設計とLCAの進展が障壁克服の機会を提供する。
English
Medicinal plant waste (MPW) is a lignocellulosic-rich feedstock promising for renewable energy and climate mitigation. This review synthesizes thermochemical conversion routes (torrefaction, pyrolysis, gasification, hydrothermal carbonization), reporting bio-oil yields of 30-55 wt%, biochar 20-35 wt%, and cold gas efficiencies of 55-70%. MPW-derived biochar can sequester roughly 2-3 t CO2-eq per tonne of dry feedstock while improving soil water retention and nutrients. Feedstock variability, technical limits, and policy gaps remain, but advances in catalyst design and LCA offer pathways to overcome them, supporting circular bioeconomy and SDG 7 and 13.

日本のGX文脈において
日本ではバイオマス発電のFIT/FIP制度や食品リサイクル法、廃棄物処理法との整合が論点となる。製薬・漢方産業の廃棄物をエネルギー・炭素隔離に転換する本知見は、国内の循環型バイオエコノミー政策やGX推進に資する。
In the global GX context
Globally, this fits the circular bioeconomy and renewable energy agenda, contributing to SDG 7 and 13. It offers evidence for waste-to-energy pathways relevant to corporate decarbonization and carbon removal accounting, though it does not directly engage TCFD/ISSB disclosure frameworks.

📄 Abstract（原文）
The development of the herbal medicine and pharmaceutical sectors has generated increasing amounts of medicinal plant waste (MPW), much of which remains underutilized or is disposed of through unsustainable practices such as open burning and landfilling.MPW contains substantial amounts of lignocellulosic biomass, positioning it as a promising feedstock for renewable energy production and climate change mitigation.This review synthesizes information on the physicochemical properties of MPW and focuses on thermochemical conversion routes, including torrefaction, pyrolysis, gasification, and hydrothermal carbonization.Studies indicate that thermochemical conversion can yield 30-55 wt% bio-oil and 20-35 wt% biochar, while achieving cold gas efficiencies of 55-70%.Hydrothermal treatment can produce hydrochar with carbon contents of 55-65% and higher heating values of 18-23 MJ kg⁻¹.Furthermore, MPW-derived biochar can contribute to carbon sequestration of approximately 2-3 t CO₂-eq per tonne of dry feedstock while enhancing soil water retention and nutrient availability.However, the large-scale valorization of MPW faces several challenges, including feedstock variability, technical constraints, environmental risks, and policy gaps.Recent advances in catalyst design and life cycle assessment provide opportunities to overcome these barriers and improve the sustainability and efficiency of MPW valorization.Overall, the valorization of MPW supports the transition toward a circular bioeconomy, renewable energy, and climate action, thereby contributing directly to Sustainable Development Goal 7 (Affordable and Clean Energy) and Sustainable Development Goal 13 (Climate Action).
