Location & approach

By Car

The campus of the Technical University of Dortmund is located near the freeway junction Dortmund West, where the Sauerland line A45 crosses the Ruhr expressway B1/A40. The Dortmund-Eichlinghofen exit on the A45 leads to the South Campus, the Dortmund-Dorstfeld exit on the A40 leads to the North Campus. The university is signposted at both exits.

By bus and train

The "Dortmund Universität" S-Bahn station is located directly on the North Campus. From there, the S-Bahn line S1 runs every 15 or 30 minutes to Dortmund main station and in the opposite direction to Düsseldorf main station via Bochum, Essen and Duisburg. In addition, the university can be reached by bus lines 445, 447 and 462. Timetable information can be found on the homepage of the Rhine-Ruhr Transport Association, and DSW21 also offer an interactive route network map.

The H-Bahn

One of the landmarks of the TU Dortmund is the H-Bahn. Line 1 runs every 10 minutes between Dortmund Eichlinghofen and the Technology Center via Campus South and Dortmund University S, while Line 2 commutes every 5 minutes between Campus North and Campus South. It covers this distance in two minutes.

By Airplane

From Dortmund Airport, the AirportExpress takes just over 20 minutes to Dortmund's main train station, and from there, the S-Bahn takes you to the university. A wider range of international flight connections is offered by Düsseldorf Airport, about 60 kilometers away, which can be reached directly by S-Bahn from the university's train station.

Glycolysis is a mild process for the chemical recycling of poly(ethylene terephthalate) (PET), but still lacks efficiency due to high waste streams. The aim of this work therefore is to facilitate recycling of ethylene glycol (EG) reactant/ solvent and homogeneously dissolved zinc acetate (ZnAc2) catalyst as well as dissolved product bis(2-hydroxyethyl)terephthalate (BHET) in the water-free PET glycolysis process. Through a combined approach of redosing and washing we saved 48.6±0.5% of EG and 50.0±5.2% of ZnAc2. By incorporating the collection of evaporated EG during BHET drying/repolymerization, additional 35% of EG could further be saved in each of the five duplicate runs. While applying an optimized washing procedure in the recycling experiments, an equilibrium PET conversion was consistently reached after 150 min of reaction time. Furthermore, the overall process yield was maintained at 80.6±1.8% in the recycling runs and the waste stream generation was reduced to a minimum. This study highlights the viability and environmental advantages of internal recycling, paving the way for a more sustainable and cost-effective PET glycolysis process.
