クラフトパルプ工場を対象に、黒液ガソ化・リグニン/ヘミセルロース価値化・熱統合・BECCSをROSES枠組みで比較したレビュー。黒液ガソ化統合でエクセルギー効率が約40%から約44%に向上し、経路別に0.3〜1.5 t CO2/パルプtのネガティブ排出が示された。経済性は製品価格・資本費・稼働率・炭素価格に強く依存し、補助金なしでの成立には炭素価格閾値が鍵となる。
English
A ROSES-based review comparing black liquor gasification, lignin/hemicellulose valorization, heat integration, and BECCS in kraft pulp mills. Integrated gasification raises exergy efficiency from ~40% to ~44%, with net negative emissions of 0.3–1.5 t CO2 per tonne pulp depending on pathway. Economics hinge on product price, capex, utilization, and carbon price, defining a subsidy-free viability threshold.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本は製紙業が多く、GX-ETSやカーボンプライシング導入議論が進む中、パルプ工場のBECCSはネガティブエミッションとScope1削減の両面で重要。炭素価格閾値の知見は国内事業者の投資判断やSSBJ開示における移行計画策定に直結する。
In the global GX context
As carbon pricing expands under EU ETS and emerging Asian schemes, this review quantifies the carbon price threshold at which BECCS in pulp mills becomes viable without subsidy. It informs transition finance and CDR accounting debates, and offers a replicable pathway framework for hard-to-abate industrial decarbonization.

📄 Abstract（原文）
Kraft pulp mills are increasingly viewed as strategic platforms for decarbonization because they combine biogenic carbon flows, chemical recovery infrastructure, and opportunities for heat and material integration within a circular bioeconomy. However, prior reviews have focused mainly on gasification and have given less attention to integrated carbon capture, high value product routes, commercial failure lessons, and pathway specific economic thresholds. We critically reviewed sources published from 2018 to 2025 using the ROSES framework and a standardized reference case of a 1000 ADt/day bleached kraft mill. The synthesis compared black liquor gasification, lignin and hemicellulose valorization, heat integration, and bioenergy with carbon capture and storage using exergy, greenhouse gas, techno economic, and technology readiness evidence. Results show that black liquor gasification-based systems can increase exergy efficiency from about 40% for conventional recovery boilers to about 44% in integrated configurations, while system expansion studies report net greenhouse gas intensities of about 0.3 to 0.6 t CO 2 below zero per tonne pulp for selected fuel and chemical pathways. Carbon capture can deepen decarbonization, but the outcome is route specific: post combustion MEA systems typically achieve about 0.3 to 0.9 t CO 2 below zero per tonne pulp, whereas pre combustion capture integrated with black liquor gasification and water gas shift can reach about 0.8 to 1.5 t CO 2 below zero per tonne pulp where transport and storage infrastructure exist. Economic performance remains highly sensitive to product price, capital cost, utilization rate, and carbon price.
