Plastic recycling system for the MINT-Mobil

In the past year 2019, a plastics recycling system was developed and constructed for the MINT-Mobile of the Environmental Campus by students of the main subject seminar of Prof. Dr.-Ing. Michael Wahl from the department of environmental planning/environmental technology. With the help of this system, it is possible to recycle plastic residues into filament for 3D printing.

In the past year 2019, a plastics recycling plant was developed and constructed for the MINT-Mobile of the Environmental Campus by students of the main subject seminar of Prof. Dr.-Ing. Michael Wahl from the department of environmental planning/environmental technology. With the help of this plant, it is possible to recycle plastic residues into filament for 3D printing.

During the summer semester, the system was developed and designed by the students together. During the development, the emphasis was placed on students being able to operate it independently, which should arouse their interest in recycling and the technical knowledge behind it. In order to present the path of recycling in the most informative way possible, the process steps of recycling were divided into individual stations: Washing, drying, shredding, extruding, and winding. Each station represents a single process step.

Plastic residues, such as PET bottles, must first be prepared before shredding. For this purpose, the bottleneck and base are removed. The bottles are cleaned, dried, and rolled flat. As soon as the bottles have been shredded by the shredder and thus reached the desired size, the material can be melted in the extruder. The finished extruded filament is wound onto a suitable spool in the last step.

To attract more people to the system, it is planned to visit schools or other institutions with a "MINT-Mobile" and to represent the department as well as the campus on site. In this way, prospective students are to be made aware of the university and sensitized for sustainability and recycling.

Special thanks go to Prof. Dr. Ing. Michael Wahl, Adrian Huwer, Michael Mattern, and our other supporters, sponsors, and partner companies.
