持続可能な化学産業への移行には、化石燃料を代替する新技術とバリューチェーンが必要です。本研究では、CCUとバイオマス経路によるポリエチレン・ポリプロピレンの共同製造を対象に、統一的な技術経済評価フレームワークを開発しました。ユーザー定義の経済パラメータ、熱力学ベースのプロセスモデル、性能評価を整合させ、各経路を公平に比較。バイオマス・エタノール経路がコスト面（1,500～3,000 EUR/t）、バイオマス・ガス化経路がエネルギー効率（32%）、CCU経路が炭素効率（64%、副生成物込みで83%）で最適と判明しました。
English
A harmonized techno-economic assessment framework for co-manufacturing polyethylene and polypropylene via CCU and biomass pathways. The biomass-ethanol route is most cost-effective (€1,500–3,000/t), gasification is most energy-efficient (32%), and CCU achieves highest carbon efficiency (64–83%). The harmonized modeling enables fair cross-pathway comparison and provides portable results for future studies.

📄 Abstract（原文）
The transition to a fully sustainable chemical industry requires new technologies and value chains, where fossil fuels are replaced as both energy source and carbon feedstock. To identify the key metrics that will make the transition viable, we developed a modeling framework for techno-economic assessment and applied it in a case study of co-manufacturing polyethylene and polypropylene from sustainable sources of carbon, viz. captured carbon utilization and biomass pathways. Differently from existing literature, our modeling framework bridges user-defined economic parameters, thermodynamic-based process models, and process performance assessment consistently throughout the different pathways. In this manner, the process designs and economic assessment are harmonized in assumption and scope, enabling a fair, detailed comparison. The results indicate that the optimal pathway depends on the specific performance metric under consideration: cost, energy efficiency, or carbon efficiency. The biomass pathway via ethanol is the most cost-effective at around 1,500–3,000 EUR/tPP+PE, the biomass pathway via gasification route is the most energy-efficient at 32%, while the carbon capture and utilization pathway exhibits the highest carbon efficiency64%, or up to 83% when including secondary products. Last but not least, details of our thermodynamic-based process models and costing method are provided, addressing the harmonization of our results and delivering portable results to other studies.
