MobilKreis conference

Following a successful launch last year, we are hosting the 2nd MobilKreis Conference in Dortmund on September 23 and 24, 2025. This year's theme is "Shaping the circular economy together: innovations between science and practice“. The conference is a platform for exchanging experiences, gathering valuable suggestions, developing new ideas, and engaging in interesting discussions. You can expect presentations, workshops, and keynote speeches that will provide inspiration for a sustainable future. Topics include the optimization of dismantling processes, the reuse of automotive components, information exchange in circular production networks, intelligent and variable process planning, and many more.

We look forward to your participation!

The conference places a strong focus on practice-orientated approaches. The aim is to prepare scientific findings and research results in such a way that they are understandable and accessible to the general public. The papers. to be prepared and the presentations .at the conference should fulfil the following criteria:

Expressiveness: The content of the papers and presentations should be clear and concise. Complex research results are presented in an understandable way in order to offer readers and listeners added value.
Public accessibility: The papers and presentations will not only be made available to conference participants, but also to the general public on the MobilKreis Hub (https://hub.mobilkreis.de/). This enables an additional and long-lasting transfer of knowledge beyond the conference.

General conditions:

Contributions: Paper with 4 - 10 pages of text (references and biographies excluded) or corporate strategies related to circular economy
Language: Conference language is German, submissions in English are also possible
Focus: Practical transfer of results based on scientific findings from your project or company
Template: Word-Template (download)

Time course:

Deadline for the contribution (Word und PDF): Extended until 13.06.2025, to benjamin.koch@mb.tu-chemnitz.de
Feedback on the article: 04.07.2025
Submission of the revised contribution: 28.07.2025
Deadline for the presentation (PowerPoint + PDF): 09.09.2025, also to benjamin.koch@mb.tu-chemnitz.de

Additional notes:

Both the contribution and the presentation will be published on the MobilKreis Hub, please note any confidentiality agreements with your partners.
The contribution can have more depth than the presentation, but the presentation should be meaningful on its own (e.g. on the MobilKreis Hub).
The paper and presentation should be prepared in such a way that they can also be understood by non-scientists.
For the practical transfer of results, it is advisable to derive concrete basic ideas and recommendations for action for companies - especially SMEs.

We look forward to a lively exchange and a successful event!

Places

PHOENIX West: Former steelworks site with impressive blast furnace backdrop. Pure industrial culture to arrive at.

Westfalen Stadium (SIGNAL IDUNA PARK): Germany's largest soccer stadium is a thrilling place to visit even when there is no game on. There are some great photo spots around the south stand and Strobelallee. You can also take a stadium tour and visit the BORUSSEUM (tickets can be purchased online or on site, opening hours 10 a.m. to 6 p.m.). In the evening, the arena is often lit up to create a special atmosphere. This can be easily combined with a short detour to Westfalenpark.

Ideal as a start/finish point for a short urban walk. Stops: Dortmunder U, Westentor (U42, U43, U44, 452)

Port of Dortmund: Industrial backdrop on the Dortmund-Ems Canal: cranes, quays, and ships. Perfect for a short evening stroll with photo stops. A creative quarter is emerging around Speicherstraße.

Tip: Take a stroll along the quay and watch the sun set over the canal. Stop: Hafen (U47 towards Westerfilde)

Activities

Urban Walk: Start at Rheinische Straße with street art around the Dortmunder U. Then continue into the trendy district with its many kiosks, bars, and small bistros.

Many establishments have outdoor terraces and are ideal for a relaxed evening out with short distances to cover.
