Europe’s petrochemical industry faces structural pressures: stagnant demand, cost disadvantages and rising decarbonization demands due to the EU Green Deal. Heavy reliance on naphtha has reduced competitiveness, while geopolitical issues expose energy vulnerabilities. Yet, integration and co-product utilization remain strengths. Evonik Oxeno’s C4-Verbund network exemplifies this resilience, turning by-products into value, securing supply chains and enhancing the robustness of value chains. Future European competitiveness hinges on cost-reduction, feedstock innovation, carbon-smart investments and collaboration across value chains.
