MOL Group has completed its first certified production trial using circular feedstock at subsidiary MOL Petrochemicals Co. Ltd. complex in Tiszaújváros, Hungary, advancing the company’s strategic push toward circular economy integration in petrochemical production. Péter Császár, senior vice-president of MOL Group Chemicals, said the pilot demonstrates that the company can process circular feedstocks at industrial scale while adhering to a certified mass-balance methodology. Certified mass-balance approachAs part of the pilot test, MOL Group introduced circular feedstock into the Tiszaújváros complex’s naphtha-based steam cracker, enabling the production of monomers (such as ethylene and propylene), which were then polymerized into PE and PP. MOL Petrochemicals in Tiszaújváros and fellow MOL subsidiary Slovnaft AS in Bratislava both received ISCC PLUS certification in 2024 for their steam-cracking and polymerization units, allowing such feedstock tracking and product attribution, the company said. MOL said it will continue trials with alternative circular feedstocks while optimizing process configurations to scale commercial operations.
