インドネシア38州を対象に、稲わら、もみ殻、トウモロコシ茎葉、パーム空果房の利用可能量と温室効果ガス・PM2.5削減ポテンシャルを評価。焼却回避でCO2換算174万トン、PM2.5を105Gg削減可能。バイオ炭化ではさらに大きな削減が見込まれるが、ライフサイクル考慮後は減少。州ごとの特性に応じた段階的実施を提言。
English
This study assesses the availability and mitigation potential of agricultural residues (rice straw, husk, maize stover, empty fruit bunches) across 38 Indonesian provinces. Avoiding burning could reduce 1.74 Mt CO2-eq and 105.3 Gg PM2.5 annually; biochar conversion offers larger but reduced benefits after life-cycle screening. The findings support differentiated provincial strategies and staged implementation.

📄 Abstract（原文）
Introduction Indonesia’s climate, air quality (AQ), and circular bioeconomy agendas require residue strategies that distinguish dispersed field burning from mill-concentrated by-products. Province-scale residue assessments can overstate mobilizable supply and mitigation when a modeled burning reference is treated as if it were observed emissions or when gross biochar storage is reported without accounting for conversion burdens. Materials and methods We conducted a screening-level material flow and scenario analysis for rice straw, rice husk, maize stover, and empty fruit bunches of oil palms across 38 Indonesian provinces using 2024 production data. A four-tier cascade quantified the theoretical, recoverable, and technical potentials. The production-normalized burning reference (S ref ), non-burning diversion (S 1 ), and biochar conversion (S 2 ) were evaluated. S ref was benchmarked against the national greenhouse gas (GHG) inventory; robustness was assessed using one-at-a-time tests and 100,000 exploratory Monte Carlo draws; and S 2 was screened using a published West Java life-cycle burden. Results Access-constrained recoverable rice straw and maize stover potentials were 17.62 and 6.46 Mt. dry matter (DM) yr. −1 , whereas technical rice husk and empty fruit bunches (EFB) potentials were 10.63 and 18.17 Mt. yr. −1 , respectively. Central S 1 outcomes were 1.74 Mt. CO₂-eq yr. −1 of avoided CH₄ and N₂O and 105.3 Gg PM₂.₅ yr. −1 ; the simulated 95% confidence interval was 1.14–3.33 Mt. CO₂-eq yr. −1 . Gross S 2 benefits of 5.78–15.28 Mt. CO₂-eq yr. −1 decreased to 5.04–13.80 Mt. after the life-cycle screen. Conclusion The results support differentiated provincial screening and staged implementation but do not establish observed 2024 emissions, health damages, cost-effectiveness, or complete life-cycle assessment (LCA).
