- Profile

Theodore Hanein (Theo) graduated with both a BSc in Chemistry (2010) and a BSc in Chemical Engineering (2011) from the University of Balamand in Lebanon. After a summer internship as a process engineering trainee in a cement manufacturing plant, he then went on to complete his Masters degree from the University of Manchester (2012) in Advanced Process Integration and Design (MSc Refinery Design and Operation). He started his doctoral studies soon after and in 2016 was awarded a PhD from the University of Aberdeen where he specialised in calcium sulfoaluminate cement technology and clinker thermodynamics. He then immediately started working as a postdoctoral research associate in the Department of Materials Science & Engineering at the University of Sheffiled. In 2021, Theo was awarded the prestigious UKRI Future Leaders Fellowship on “Green, Circular, and Smart Cement Manufacture”.
Theo is highly experienced in thermochemistry and his research centres around green, circular, and smart materials and their processing; his main area of research is in sustainable cement production. He is highly experienced in cement clinker formulation and pyro processing, including the successful scale-up and pilot demonstration of the production of novel low-carbon cement clinkers on several occasions. He is responsible for pioneering the use of atmospheric control during clinker manufacture, for quality control and to produce novel clinkers. Theo developed the first thermodynamic database that is tailored specifically for cement clinkering and is experienced in kiln heat transfer modelling. He is involved in several projects, promoting a circular economy, resource efficiency, industrial decarbonisation, industrial symbiosis, and producing novel sustainable materials (e.g., clinker, cement, and concrete) and processes; in this regard, he has also consulted for several multinational corporations. The word cloud shown summarises his research track record.
