混合プラスチック廃棄物を熱分解、電化クラッキング、圧縮、分離によりポリマー級オレフィンに変換するプロセス設計とライフサイクルGHG分析を提示。集中型・分散型、CHP・全面電化、系統電力・再生可能電力の8シナリオを評価。陸上風力電力を想定するとGHG排出はHVC 1kgあたり約0.08kg CO2-eqとなり、EUの2040年目標（従来比90%削減）を達成可能。ただし輸送距離が160-180km以内に限定される。

This study presents a conceptual process design and life-cycle GHG analysis for converting mixed plastic waste into polymer-grade olefins via pyrolysis, e-cracking, compression, and separation. Eight scenarios are assessed, combining centralized/decentralized configurations, CHP vs. fully electrified operation, and grid vs. renewable electricity. With onshore wind power, GHG emissions drop to ~0.08 kg CO2-eq per kg of high-value chemicals, meeting the EU's 2040 climate target of 90% reduction relative to conventional naphtha cracking, provided transport distances stay within 160-180 km.

📄 Abstract（原文）
Abstract This work presents the conceptual process design and life-cycle Greenhouse Gas (GHG) analysis for converting mixed plastic waste (MPW) into polymer-grade olefins (≥99.9 wt % ethylene and propylene) via sequential pyrolysis, e-cracking, compression, and separation. The integrated plant-wide process modeling was performed within a Python-based framework as an alternative to conventional commercial simulators. Eight scenarios were assessed by combining centralised and decentralised configurations, combined heat and power (CHP)-powered and fully electrified operation, and grid versus renewable electricity supply. Under fully electrified conditions, the carbon footprint strongly depends on the electricity source. When onshore wind-harvested electricity is assumed, GHG emissions decrease to ∼0.08 kg CO2-eq per kg of high-value chemicals (HVCs), placing the process within the EU’s 2040 climate objective of a 90% reduction relative to the sector’s conventional benchmark (i.e., naphtha steam cracking, ∼1 kg CO2-eq per kg of HVC). Sensitivity analysis showed that transport-related emissions are a significant contributor in the fully electrified scenario. In particular, maintaining the targeted 90% GHG reduction relative to the conventional benchmark is only feasible for MPW transport distances of ∼ 160–180 km.
