The emission of organic halogen compounds into the environment causes serious and irreversible damage. The University of Miskolc, the Budapest University of Technology and Economics (BME), and the EGIS Pharmaceuticals PLC had started research a decade before the European Union Environment Technology Verification (ETV) program was launched. As a result, they developed a novel and unique method that can remove the polluting organic halogen compounds from process wastewater, making it possible to discharge these compounds and to prepare them in a concentrated form so that they can be reused. The technical and economic efficiency of the patented process invented by prof. Péter Mizsey and his team has been proven and acknowledged by an international jury and independent experts. Dr Péter Mizsey works as a full professor at the University of Miskolc and the BME. Between 2006 and 2016, he was the head of the Department of Chemical and Environmental Process Engineering. From 2017, he is the head of the Department of Fine Chemicals and Environmental Technology at the University of Miskolc. His field of education and research is chemical unit operations, environmental processes engineering, and process control. He is also a member of the European Academy of Sciences and Arts. His major achievements and awards include the MOL Scientific Award, the 2004 MTA Varga József Prize and Medal, 2011; the KÖVET Organization Eco-Design Award, the BME Pro Progressio Innovation Award, the Budapest Water Summit - Professional Award, the IChemE (Institution of Chemical Engineers) Global Award, and the Vitális Sándor Award. Prof. Dr József Manczinger, professor emeritus, was a trainee at the Faculty of Chemical Engineering, BME, from 1957. Between 1982 and 1994, he was the head of the Department of Chemical Unit Operation. From 1988 to 1993, he was the vice-dean in scientific affairs of the Faculty of Chemical Engineering. From 1996, he worked as a retired full professor. He was awarded the MTA Varga József Prize in 1996 and the BME Pro Progressio Innovation Award in November 2016. He passed away on 31 December, 2016, at the age of 84. Dr András József Tóth, senior lecturer, has worked at the BME since 2011 and got his PhD degree in 2015 there. From 2016, he is an assistant professor and laboratory head. His field of education and research is chemical unit operations and technical chemistry. He is an expert of the National Accreditation Authority - European Union Environmental Technology Verification (EU - ETV). He has received many awards: Lászlóffy Woldemár Award, Hungarian Chamber of Engineers – Environmental Engineering Award, Greennovation Award, KÖVET Organization Eco-Design Award, Soós Ernő Young Researcher Award, BME Pro Progressio Innovation Award, Budapest Water Summit - Professional Award, IChemE (Institution of Chemical Engineers) Global Award, BME Rector Praise, and Vitális Sándor Award. Gábor Réti, director of the EHS division at EGIS PLC, finished his studies in 1985 at the Technical University of Budapest as a chemical engineer. He did two postgraduate engineering degrees in pharmaceutical chemistry and in environmental protection, and worked in API production areas in several positions, as section leader, plant master, and head of environment protection affairs. Since 1985, he has worked at EGIS, motivated to complete environmental-protection-oriented innovations. László Tölgyesi, chemical engineer at EGIS, actively participated in the construction of the new method. Professor Mizsey and his team have shown that it is possible to achieve great results and to contribute to the circular economy at the same time.
