Management
(co-founder & managing director)
Dr. Evangelos Delikonstantis
Evangelos Delikonstantis was born in Larisa, Greece on the 19th of April 1989.
He earned his bachelor and master’s degree in chemical engineering from the Aristotle University of Thessaloniki in 2012, ranked first in his cohort. In 2015, he completed the Professional Doctorate in Engineering from the Delft University of Technology, the Netherlands, with honors, specialized in Process and Equipment Design. For his thesis, he worked on the conceptual process design of a novel PET chemical recycling process for Ioniqa Technologies B.V. Afterwards, he joined USG Engineering Professionals, serving as engineer consultant in power, process and production systems.
In 2016, he joined the Catholic University of Leuven (KU Leuven) as a PhD candidate in the Department of Chemical Engineering under the supervision of Prof. G. D. Stefanidis. His PhD project focused on the development of plasma-assisted reactor systems for rich-in-methane gas streams valorization to olefins. In 2016, he was granted a scholarship by the KIC-InnoEnergy PhD school for customized training on innovation and entrepreneurship. Afterwards, he joined the Laboratory for Chemical Technology (LCT) of Ghent University as postdoctoral researcher.
His latest interests and research activities are focused on electrified chemical processes for CO2, biomass and natural gas valorization, conceptual processes design and life cycle assessment.
(co-founder & CTO)
Dr. Stavros Theofanidis
Stavros-Alexandros Theofanidis was born in Ptolemaida, Greece on the 16th of November 1989.
He received his bachelor and master’s degree in chemical engineering on April 2013 from the Chemical Engineering Department of Aristotle University of Thessaloniki. In January 2014, he joined the Laboratory for Chemical Technology (LCT) of Ghent University, to pursue a PhD degree under the supervision of Dr. Vladimir Galvita and Prof. Guy Marin, from where he graduated on October 2017. He further stayed as a postdoctoral researcher in Ghent university until June 2018. His work focused on syngas production and CO2 utilization, actively involved in catalysts synthesis, characterization and testing using advanced in-situ and operando techniques.
In July 2019, he joined the Laboratory of Petrochemical Technology in Aristotle University of Thessaloniki as a postdoctoral researcher where he was involved into two projects: CO2-assisted oxidative dehydrogenation of alkanes (supported by Hellenic Foundation Research & Innovation, HFRI-FM17-1899) and valorization of plastic waste pyrolysis gases back to monomers (H2020 MSCA ITN C-PlaNeT).
His latest research activities are focused on catalytic processes for CO2 abatement, light olefins production, plastic waste valorization, processes design and life cycle assessment.

Chemical Engineer
Dr. Vasileia-Loukia Yfanti
Vasileia-Loukia Yfanti was born in Rhodes, Greece on the 18th of October 1988.
She received her bachelor and master’s degree in Chemical Engineering on April 2013 from Aristotle University of Thessaloniki. In 2018, she received her Ph.D, from the Department of Chemical Engineering at the same university, supervised by Prof. Angeliki Lemonidou. Her PhD project focused on the development of a tandem catalytic process of glycerol hydrodeoxygenation – methanol reforming reactions to 1,2-propanediol production, without the need for external hydrogen supply. Afterwards, she continued her research as a postdoctoral researcher at Laboratory of Petrochemical Technology at Aristotle University of Thessaloniki.
Her research activities mainly focused on the effective upgrading of biomass derived feedstocks to target chemical products and fuels, actively involved in catalyst synthesis, structural characterization using advanced temperature programmed and spectroscopic techniques and catalytic evaluation on laboratory scale reactors under high pressure conditions. She was also active in reaction kinetic and mechanistic studies.
Her latest research activities are focused on catalytic upgrading of plastic waste pyrolysis oil wax-like products to a mix of lighter naphtha-like hydrocarbons, on process design and life cycle assessment.
