Curriculum Vitae
Saqib Javed studied Bachelor of Science in Chemical Engineering from the Institute of chemical engineering and technology (ICET), University of the Punjab, Lahore-Pakistan in (2007-2011) and Master of Science in Chemical Engineering on Saudi Govt. Higher education Ministry scholarship from King Fahd University of Petroleum and Minerals (KFUPM), Dhahran (2013-15). He graduated with Master thesis titled “Fouling Mitigation of Reverse Osmosis Membrane using Layer by Layer (LBL) deposition of Polyelectrolytes”.
He served as a Lecturer in University of Wah, Wah Engineering College, Wah Cantt, Pakistan for one year (2016) and then in University of Engineering and Technology Lahore (New Campus), Pakistan for two years before he joined the TU dortmund.
In 2019, he joined TU Dortmund University as a DAAD scholar for doctoral studies (promotion) under the supervision of Prof. Dr. Dieter Vogt at the chair of industrial chemistry.
Research Topic
Polyethylene terephthalate (PET) waste is mounting up in the environment due to its poor biodegradability and low recycling rate. Glycolysis of PET is a promising chemical recycling technique to convert post-consumer PET waste into its monomer bis(2-hydroxy ethylene erephthalate) (BHET). The research topic includes the optimization of operating parameters influencing the chemical depolymerization of PET waste, thermodynamic and kinetic evaluation, improvement in the glycolysis methodology, optimization of crystallization conditions and investigating the suitability of synthesized BHET monomer into useful product.
The schematic diagram of the glycolysis process is as follows:
