本論文は、プラスチック廃棄物を製油所で処理可能な「ポリクルード」に変換する二つの水素化分解経路を評価。確率論的技術経済分析と温室効果ガス排出量計算により、20%のケースで原油価格を下回る最低販売価格を達成するものの、収益性には厳しい条件が必要であることを示した。排出量は電力構成と水素経路に強く依存する。
English
This study evaluates two hydroconversion pathways (hydrocracking and hydrogenolysis) for converting plastic waste into refinery-compatible 'poly-crude'. Using probabilistic techno-economic analysis and GHG emission calculations, it finds that 20% of simulated cases achieve profitability below benchmark crude oil prices, but only under stringent conditions: hydrocracking with on-site green hydrogen, yields above 90%, feedstock below $0.3/kg, and capacity over 250 tons/day. GHG impacts are highly scenario-dependent.

In the global GX context
Globally, plastic waste recycling faces cost and efficiency barriers. This paper provides the first probabilistic, system-level assessment of poly-crude production, highlighting key performance targets (yield, feedstock cost, scale) for cost-competitive recycling. The findings are relevant for petrochemical companies and policymakers aiming to integrate circular economy with decarbonization via hydrogen pathways.

📄 Abstract（原文）
High Resolution Image Download MS PowerPoint Slide Plastic waste recycling remains constrained by limited cost competitiveness and energy-intensive conversion and separation. Here, we evaluate the conversion of plastic waste into refinery-compatible “poly-crude” as a pathway for plastic reintegration into existing petrochemical infrastructure, potentially eliminating the need for dedicated downstream upgrading facilities and associated capital investments. We present an early-stage, system-level sustainability assessment of poly-crude production, evaluating two hydroconversion pathways (hydrocracking and hydrogenolysis) and multiple hydrogen supply strategies. Economic performance was assessed using probabilistic technoeconomic analysis integrating process modeling, Latin hypercube uncertainty sampling, and global sensitivity analyses, while environmental performance was evaluated through scenario-based greenhouse gas (GHG) emission calculations. Results show that 20% of simulated cases achieve poly-crude minimum selling prices (MSPs) below the benchmark crude-oil price, indicating constrained profitability. Scenario analysis reveals that profitability requires hydrocracking with on-site green hydrogen production, poly-crude yields above 90%, feedstock prices below $0.3 kg −1, and capacities exceeding 250 tons day −1 . GHG emissions are highly sensitive to the electricity mix and hydrogen conversion pathway, making any potential benefits relative to crude oil strongly scenario-dependent. This work provides the first probabilistic, system-level evaluation of plastic waste hydroconversion to refinery-compatible intermediates and identifies key performance targets and research priorities for improving process viability.
