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.
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:

Location & approach
The campus of TU Dortmund University is located close to interstate junction Dortmund West, where the Sauerlandlinie A 45 (Frankfurt-Dortmund) crosses the Ruhrschnellweg B 1 / A 40. The best interstate exit to take from A 45 is “Dortmund-Eichlinghofen” (closer to South Campus), and from B 1 / A 40 “Dortmund-Dorstfeld” (closer to North Campus). Signs for the university are located at both exits. Also, there is a new exit before you pass over the B 1-bridge leading into Dortmund.
To get from North Campus to South Campus by car, there is the connection via Vogelpothsweg/Baroper Straße. We recommend you leave your car on one of the parking lots at North Campus and use the H-Bahn (suspended monorail system), which conveniently connects the two campuses.
TU Dortmund University has its own train station (“Dortmund Universität”). From there, suburban trains (S-Bahn) leave for Dortmund main station (“Dortmund Hauptbahnhof”) and Düsseldorf main station via the “Düsseldorf Airport Train Station” (take S-Bahn number 1, which leaves every 20 or 30 minutes). The university is easily reached from Bochum, Essen, Mülheim an der Ruhr and Duisburg.
You can also take the bus or subway train from Dortmund city to the university: From Dortmund main station, you can take any train bound for the Station “Stadtgarten”, usually lines U41, U45, U 47 and U49. At “Stadtgarten” you switch trains and get on line U42 towards “Hombruch”. Look out for the Station “An der Palmweide”. From the bus stop just across the road, busses bound for TU Dortmund University leave every ten minutes (445, 447 and 462). Another option is to take the subway routes U41, U45, U47 and U49 from Dortmund main station to the stop “Dortmund Kampstraße”. From there, take U43 or U44 to the stop “Dortmund Wittener Straße”. Switch to bus line 447 and get off at “Dortmund Universität S”.
The AirportExpress is a fast and convenient means of transport from Dortmund Airport (DTM) to Dortmund Central Station, taking you there in little more than 20 minutes. From Dortmund Central Station, you can continue to the university campus by interurban railway (S-Bahn). A larger range of international flight connections is offered at Düsseldorf Airport (DUS), which is about 60 kilometres away and can be directly reached by S-Bahn from the university station.
The H-Bahn is one of the hallmarks of TU Dortmund University. There are two stations on North Campus. One (“Dortmund Universität S”) is directly located at the suburban train stop, which connects the university directly with the city of Dortmund and the rest of the Ruhr Area. Also from this station, there are connections to the “Technologiepark” and (via South Campus) Eichlinghofen. The other station is located at the dining hall at North Campus and offers a direct connection to South Campus every five minutes.
The facilities of TU Dortmund University are spread over two campuses, the larger Campus North and the smaller Campus South. Additionally, some areas of the university are located in the adjacent “Technologiepark”.
