This paper presents a multi-objective optimization framework integrating industrial symbiosis (IS) and carbon capture utilization (CCU) for net-zero industrial parks. Applied to Portugal's largest industrial park, the model identified 26 symbiotic exchange routes and 7 CCU technologies, achieving 87-90% reduction in climate impact while generating €65.5M/year net revenue. Methanol production from CCU emerges as a critical pathway.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本の産業団地（コンビナート）におけるカーボンニュートラル戦略に示唆を与える。特に、工業共生とCCUの統合最適化は、日本の化学・鉄鋼コンビナートの脱炭素化に応用可能。ただし、日本のCCU実証規模やコスト構造はポルトガルと異なるため、国内データでの再検証が必要。
In the global GX context
This framework offers actionable optimization strategies for industrial parks globally, especially relevant for regions with high industrial concentration like Europe and East Asia. The integration of IS and CCU with multi-objective trade-off analysis provides a methodology applicable to GHG-intensive clusters. The results highlight methanol as a key CCU product, aligning with global interest in e-methanol.

📄 Abstract（原文）
The integration of industrial symbiosis (IS) and carbon capture utilization (CCU) is recognized as a key strategy for achieving net-zero emissions in industrial parks (IPs). However, the optimization of these processes in combination remains an undeveloped research area. This work presents a multi-objective optimization framework implemented in Pyomo and linked with OpenLCA to simultaneously maximize material exchanges and minimize operational costs while evaluating CCU deployment. Applied to Portugal's largest industrial park, the model identified 26 feasible symbiotic exchange routes involving 14 enterprises and 7 potential CCU technologies. Maximum material exchange optimization yields 3,042,107 ton/year across 26 symbiotic routes and 7 CCU units, achieving 89.8 % reduction in climate change impact (from 13.5 to 1.76 million CO2eq/year); Cost minimization achieves 2,223,298 ton/year with 27 % fewer exchanges, delivering 87.0 % environmental reduction and net revenue of €65.5M/year via carbon tax avoidance. The proposed trade-off configuration deploys 2 CCU units (both for methanol production), establishes 12 symbiotic routes, exchanges 2,925,556 ton/year, and generates €65.5M/year net benefit. Decision variables encompassed inter-enterprise flows, binary decisions to select exchanges, and CCU unit selection informed by technology readiness level (TRL). The epsilon-constraint method generated a Pareto front revealing the cost-benefit trade-offs of the symbiotic network. IS with CCU integration can reduce IP climate impact by 87-90 % while generating substantial economic returns. Methanol emerges as the critical CCU pathway for replacing fossil-imported feedstocks. This framework provides decision-makers with actionable optimization strategies for achieving near net-zero industrial parks by 2050, not only through CCU but also through IS.
