Circular Valley Forum 2025: A day full of inspiration – and a decisive step for Europe
The event impressively demonstrated the high level of willingness to engage in exchange and joint development. At the same time, the new trilateral agreement between North Rhine-Westphalia, Flanders, and the Netherlands marked an important European milestone.
On 14 November, the Circular Valley Forum 2025 brought together more than 1,200 decision-makers from politics, business, science and civil society to demonstrate the importance of the circular economy for Europe, and to showcase the power that can be generated when regions and different industries collaborate. The motto of this year's forum was “Action Across Borders and Industries”.

The forum generated strong momentum right from the start: following opening statements by Dr. Thomas Stoffmehl (Vorwerk) and Dr. Dorothee Becker (Becker Group) and a keynote address by North Rhine-Westphalia Minister of Economic Affairs Mona Neubaur, numerous panels demonstrated how far the circular economy has already developed in many industries. Dr. Thomas Latzel, President of the Protestant Church in the Rhineland, provided a special social insight: the circular economy also touches on issues of responsibility, social participation, and the preservation of creation.

Lively exchange also between the panels

Throughout the day, experts from the metals, chemicals, and building materials industries discussed new technologies, rising recycling rates, and the conditions required for scalable solutions. The European perspective also played a central role, with delegations from North Rhine-Westphalia, Flanders and the Netherlands presenting their close cooperation and the potential of the trilateral region as a core area of the European circular economy. Pitches from startups in Batch 9 of the Circular Economy Accelerator demonstrated which new technologies are close to market maturity.

The afternoon sessions focused on topics such as digital product passports, innovation structures, regional cooperation, and the role of the tech industry in circular processes. But it wasn't just the program that shaped the day; it was also the special atmosphere at the Circular Valley Forum: "You could feel how much willingness there was to exchange ideas. That was exactly what we wanted: for people not only to discuss issues in the panels, but also to meet each other in between, share ideas, and think ahead together," says Dr. Carsten Gerhardt, Chairman of the Circular Valley Foundation. The participants enjoyed talking to each other—across their own industries and professional fields.
The forum thrives on this energy, which was palpable throughout the day. This joy of exchange is a key driver of transformation.

Highlight of the day: The trilateral agreement

In the evening, leading representatives from North Rhine-Westphalia, Flanders and the Netherlands signed a joint declaration on cooperation. This officially expands the existing collaboration between North Rhine-Westphalia and Flanders to encompass the Netherlands. NRW Environment Minister Oliver Krischer emphasised the importance of signing the declaration: 'I am very pleased that we now have comprehensive cooperation with the Netherlands and Flanders, which will further strengthen our regional expertise and expand our exchanges, enabling us to have a broader impact.'

Krischer also emphasised the importance of the circular economy in addressing the major challenges of our time. 'When it comes to climate protection and adaptation, the circular economy is key. It is the answer to ensuring a sustainable future for our planet and managing our limited resources. It is an ecological solution, but also an economic one.”

Implementation begins immediately upon signing

Work began immediately after the signing ceremony. “We sat down together straight away and started planning the next steps,” says Dr. Carsten Gerhardt. Representatives from all three regions discussed developing concrete proposals for actions and projects that would be taken beyond the regions and presented to Brussels.

Gerhardt sees this as a strong sign. "The Circular Valley Forum should be a place for implementation, not announcements. That is exactly what happened today. Today showed how much can be achieved when people who really want to make a difference come together.”
The date for the 2026 forum has already been set: November 13, 2026.

Startups
Batch 9 at Circular Valley: Three weeks full of exchange, insights, and innovation
In the autumn, fourteen international start-ups came together for an intensive accelerator programme in the Rhine-Ruhr region. The founders were provided with valuable inspiration for the next stage of their development through workshops, coaching sessions, visits to Knipex and Remex, and Demo Day.
In autumn, the Circular Economy Accelerator welcomed Batch 9 startups to Circular Valley. Teams from all over the world came together in the Rhine-Ruhr region for several intensive weeks, during which they participated in a diverse programme designed to impart knowledge, facilitate networking and advance the founders' business ideas.
  • A successful start and valuable insights from alumni
    This year's kickoff on October 27 was an energetic start that brought the teams closer together. Right from the start, the founders received practical, first-hand advice: Accelerator alumni rhinopaq and Volterica shared their experiences, tips, and stumbling blocks on their own path to success as startups in a format called “What to expect from the program.”
  • Workshops, coaching sessions, and practical inspiration
    As in every funding round, workshops and coaching sessions played a central role. The body language workshop was very well received, helping young entrepreneurs to appear confident on stage and reduce stage fright.

    Storytelling was also a central theme: in the workshop “Fine-tuning your storytelling,” Joachim Lachmuth, former editor of the children's TV show Die Sendung mit der Maus, provided insights into clear communication and effective narratives.

    Questions relating to intellectual property and the workshop “How to talk to investors” were also on the agenda, formats that are regularly among the highlights of the accelerator program because they lead directly to the practical aspects of investor search and company development.

    In addition, the startups received individual support in business model coaching from Circular Valley Chief Scientist Prof. Thomas Müller-Kirschbaum and in pitch training from Maximilian Merklinger from Kearney. The initiator of Circular Valley was also heavily involved in coaching the startups.
  • Company visits: A look behind the scenes
    Once again, the insights gained into companies from the Circular Valley network proved particularly valuable. At Knipex, the group gained insights into processes and innovation projects at this long-established company. A second company visit took the teams to Remex, part of the Remondis Group. There, they toured facilities in Oberhausen and Essen, gaining practical insights into recycling processes that sparked discussions about scaling, material flows, and technological solutions.
  • Exchange and networking
    The supporting program included a visit to the Zollverein Coal Mine Industrial Complex, which not only provided an insight into industrial culture, but also offered plenty of opportunity for personal exchange. Another highlight was the Circular Valley Alumni Night: on November 13, the teams met alumni, mentors, and representatives from partner companies—a “family reunion” full of conversation, inspiration, and new contacts.
  • Circular Valley Forum, Demo Day, and Green Impact Award
    One highlight was the Circular Valley Forum with Demo Day. In front of a large audience, the startups presented their solutions for a functioning circular economy, received direct feedback, and had the opportunity to meet potential partners. The forum also featured the presentation of the Green Impact Award by the Aurel Steiner Foundation, an inspiring conclusion that showcased the innovative strength of the participating teams.

    With many new contacts, valuable insights, and strengthened business models, the founders are now alumni of the Circular Valley Community and thus part of the network.

Partnertalk
How the plastics industry is becoming more circular
The Circular Valley Partner Talk at the leading plastics trade fair K 2025 at Messe Düsseldorf
At the latest Circular Valley Partner Talk at the leading plastics trade fair K, companies and institutions discussed concrete ways to achieve greater sustainability. Insights from the tour of the fair, the keynote speech, and the discussion show how diverse the approaches to a circular plastics economy are.
Plastics are a key issue in the circular economy. At the same time, the circular economy is an important topic in the plastics industry.
Both of these issues were highlighted at the latest Circular Valley Partner Talk at the Circular Valley Partner Messe Düsseldorf, where representatives of partner companies and institutions met at the leading plastics trade fair K.

The meeting began with a tour of the K trade fair and visits to the stands of Evonik, Plastics Europe, Pöppelmann, and Der Grüne Punkt, i.e., companies along the value chain: from chemical raw materials to production and processing to recycling. The respective companies presented their activities and highlighted their approaches to the circular economy.

Wolfram Diener: The trade fair itself also wants to become more circular and sustainable

Following the tour, Wolfram Diener, CEO of Messe Düsseldorf and host for the day, welcomed the group and shared his experience that the circular economy is not only an important topic in many industries that present themselves at trade fairs, but that the trade fair itself is also striving to become more circular and sustainable.

In a very concise keynote speech, Dr. Christine Bunte, Managing Director of Plastics Europe, gave an overview of the current situation in the European plastics industry, particularly with regard to how it can become more sustainable and circular. She presented the various mechanical and chemical recycling processes and showed how they can complement each other.

Chemical recycling methods are needed where mechanical methods reach their limits

This is not a question of “either/or,” but rather a nuanced consideration of “what when?” All recycling technologies are needed. They must be combined. For example, chemical recycling methods make sense when mechanical methods reach their limits. Likewise, extending product life, reuse, and intelligent product design are important for a sustainable plastics industry.

In the ensuing open discussion, against the backdrop of higher production costs and market-related challenges in terms of demand, the focus was on how the political framework conditions could be improved. Topics included more efficient reporting requirements, affordable energy prices, the role of recycled content quotas as an incentive system, and finally, how important it is for the German economy to advocate for ambitious goals at the European level.

Educational Work
Practical and creative: Circular Valley brings the circular economy to life
From the forum and the scouts project to journeys into the future: Circular Valley opens up exciting opportunities for young people to actively shape the circular economy.
The Circular Valley Foundation's educational work is constantly evolving. Its current projects demonstrate how practical and motivating learning about the circular economy can be.
  • Students at the Circular Valley Forum: Networking and pitch enthusiasm
    Around 50 students took part in the networking event for student companies as part of the Circular Valley Forum. Inspired by the pitches from Batch 9, almost half of the group expressed a desire to pitch on such a big stage themselves one day. They also took the opportunity to make valuable contacts with the startups.

    The event was a resounding success and marks a successful start to the collaboration between Circular Valley and the Kurs21 association. The association is a regional education network that is guided by the principle of sustainability and develops and implements a wide range of educational programs at the interface between schools and business.

    The cooperation partners are planning another exciting event for schoolchildren at the Circular Valley Convention. A preparatory workshop will be held on January 12, 2026, where young people will have the opportunity to contribute their own ideas and wishes.
  • Circular Valley Scouts: Companies and students on the same track
    The project “Circular Valley Scouts – On the Trail of the Circular Economy,” which is funded by the Environment and Development Foundation of North Rhine-Westphalia, is also continuing to take shape. The companies Knipex, Vorwerk, AWG, WSW, Gebr. Becker, and Gebr. Jaeger from the Circular Valley network are participating. Together with the students, the project brings circular solutions to life. The acquisition of schools is currently underway, and some places are still available.
  • Journey into the future: “Fair and Circular”: Young ideas for Wuppertal
    Another highlight is already on the calendar: On January 30, 2026, Circular Valley and Transformation Wuppertal invite you to join them on a journey into the future entitled “Fair and Circular.” The journey into the future will be based on the Future Journey model developed by the Future Design Academy (Klaus Kofler and Holger Bramsiepe). School students will work together with representatives from business, politics, and administration to develop approaches for a fair and circular economy.
Circular Valley thus demonstrates once again how education for sustainable development can be put into practice: with enthusiasm, interaction, and the opportunity for the next generation to realize their own ideas.

TraWeBa
Study on the role of German mechanical engineering in battery production published
How can German mechanical engineering excel in battery production? A new study commissioned by the Circular Valley Foundation provides a comprehensive analysis of Germany's strengths and areas where Europe urgently needs to catch up.
Batteries are a key technology for the energy transition, playing a vital role in electric vehicles, stationary storage, and smart energy systems. At the same time, Europe is facing major challenges in global competition. In particular, China has enormous economies of scale and decades of production experience. Production costs are also significantly higher in this country.

Against this backdrop, the Circular Valley Foundation commissioned the study “Identifying the potential and players in mechanical engineering for battery production in Germany” as part of the TraWeBa project. The study provides the first systematic overview of German mechanical and plant engineering companies along the entire battery value chain and clearly shows that the expertise is there, but industrialization must be driven forward more quickly and consistently.
The new study, commissioned by the Circular Valley Foundation, provides the first systematic analysis of Germany's strengths and Europe's urgent needs in battery production.
The analysis clearly shows that German technology providers offer robust solutions for almost every stage of the process: from mixing and coating to calendering, forming, and end-of-line testing. However, large-scale production lines that have been optimised over many years to balance cycle times, yields and costs as efficiently as their Asian competitors' are still lacking. However, there are also some promising strengths: companies such as Dürr and GROB are investing in forward-looking technologies, including dry electrode processes and high-precision calendering technology. Technological leadership can emerge in such niches in the short term.

The study outlines two potential development paths for Europe.
  • Joint European production model
    The first is a joint European production model comparable to the division of labour organised for the construction of the Airbus aircraft. This model aims to establish resilient, scalable cell production, albeit with a long lead time.
  • Specialising in specific niches
    The second path involves specialising in specific niches, such as process technology excellence, digital production control and quality assurance.
This would enable the mechanical engineering sector to have a faster impact and offer more attractive international solutions.

In the short term, according to the authors, Europe needs affordable batteries above all else—including through imports. At the same time, however, new regulatory requirements are opening up major opportunities in recycling: rising minimum quotas for efficiency and recycled materials are creating a growing market environment in which German technology providers can score points.
The study was also featured on the renowned online portal Battery News. The article on the study is available here.

The full study can be downloaded free of charge here.
Success
Circular Valley startups take off: New milestones from the alumni network
Once again, the alumni of the Circular Economy Accelerator are making impressive progress, from launching new pilot plants and achieving research successes to receiving awards, bringing products to market, and collaborating internationally.
The alumni are once again demonstrating how diverse and effective circular innovations can be. In recent months, numerous startups from different batches have reached important milestones, formed new partnerships, and brought their technologies to market.

The first SapoCircle pilot plant has been installed at La Badira, Tunisia by Monsapo from Batch 8. Monsapo develops machines that convert used cooking oil into natural cleaning products, demonstrating how cleaning systems can be designed to conserve resources. The pilot plant is an important step towards the widespread adoption of this technology.

Revoltech from Batch 3 is also setting new trends: Leica has unveiled a new watch strap made from LOVR, the startup's plant-based, plastic-free material. It is now part of the brand's official accessory range. Revoltech is also working on further optimizing its algae-based textile leather in the new WATER research project, funded by the German Federal Ministry of Education and Research.
  • Sustainable solutions for people and the environment
    Ecoplastile from Batch 2 has further developed its “Waste for Health Insurance” program—the first green insurance plan that uses five kilograms of recyclable plastics as a contribution for low- and middle-income people in Uganda. Para-excel, also from Batch 2, has had its main product, Phytorbit, NAFDAC-certified and has launched BioRustGuard, a completely plant-based corrosion protection product. The antimicrobial spray Phytorbit protects food from farm to market and reduces post-harvest losses.

    Shards from Batch 2 is currently building a tile production facility in the Münsterland region. The glazing line has now been delivered for this purpose. This machine is the heart of the surface finishing process and contributes significantly to the quality and aesthetics of the finished Shards tiles. The company manufactures tiles from construction waste and does not use any primary raw materials.

    Space Era, also from Batch 2, was given the opportunity to present its modular architecture at Expo Real 2025 in Munich, one of the world's largest real estate trade fairs. Biomyc from Batch 3 won an award from the EIT Food Accelerator Network for its work with fungus-based materials, while Gescol – also Batch 3 – was certified as a MITIGATING solution based on its life cycle analysis of recycled products from safety boots.
  • Awards and international recognition
    Further successes demonstrate the breadth of the alumni network: Radical Dot from Batch 6 was among the winners of the Santander X Global Challenge, and T-Phite from the same batch was accepted into the TUM Venture Lab ChemSPACE and received the Crowd Favorite Award at the Advanced Materials Competition 2025.

    ContainerGrid from Batch 6 participated in the MassChallenge ClimateTech program in Boston, strengthening its presence in the US market. Resourcly from Batch 7 won the Mannheim Start-up Award and raised €2.7 million to help manufacturers use their resources more efficiently.
  • Market successes and strategic partnerships
    ChemSmog from Batch 8 reports over 500 tons sold, representing 825 percent year-on-year growth. The startup supports chemical companies in managing their hard-to-sell inventories via a digital marketplace that connects them with buyers.
    Folgrid Technologies is working on two Spanish agrivoltaic pilot projects and has been able to establish valuable partnerships through the Circular Valley network: with the Jülich Research Center and the University of Bari.

    From Batch 8, Simplyfined won two prizes at the Senkrechstarter Award, Vlastic was accepted into the Raise Cohort of Impact Shakers, and Volterica secured a place in the Bryck Energy Accelerator. Finally, from Batch 9, AraBat impressed the jury of the Adriano Olivetti Prize in the “Change” category with its bio-based solution for recovering critical raw materials from lithium batteries.
The numerous successes show that startups from Circular Valley are growing, networking, and bringing their innovations to where they are needed—into the practice of a circular future.

Podcast
“Welcome to Circular Valley” – Listen to the future of the circular economy
With a diverse range of guests and relevant topics, “Welcome to Circular Valley” has become a key point of reference in just a few months. The podcast highlights players, ideas, and trends that are setting cycles in motion.
Since the beginning of the year, the podcast “Welcome to Circular Valley” has been taking its listeners on an ever-expanding journey through the circular economy. What started in January as a new format from the foundation has developed into a reliable platform for knowledge, perspectives, and concrete solutions in just a few months.

The topics range from material innovations and circular construction to chemical recycling and AI applications to issues of waste management, agriculture, and financing. Startups that work with innovative approaches—such as sustainable packaging, new materials, or the handling of electronic waste—are repeatedly given a voice. In addition to young companies, established players also provide insight into their processes: from manufacturers who are rethinking product design to organizations that strengthen regional cycles or bring digital solutions to industry.
The podcast “Welcome to Circular Valley” has been available on all popular platforms since the beginning of the year.
Previous guests have included Dana Aleff, co-founder and managing director of Circonomit, Dr. Peter Stemper, member of the board at NRW.BANK, Montgomery Wagner from revoltech, Dr. Thomas Rodemann from Vorwerk, and Felicitas Erfurt-Gordon, managing partner at Erfurt & Sohn.

A live recording on the introduction of the digital product passport, which is set to play a key role in making material flows more transparent in the future, recently received particular attention. One of the podcast's strengths is that it also addresses such current debates and brings different perspectives into the dialogue.

A recurring element also provides surprises time and again: at the end of each episode, the guests describe what they currently need or are looking for in their work. This ranges from specific research questions to approaches for collaboration. For many listeners, it is therefore particularly worthwhile to listen to the last few minutes of an episode—they often open doors to new projects, partners, or ideas.

Outlook: New voices, new topics

Many exciting episodes are still to come: in the coming weeks, for example, interviews are planned with Carsten Cramer, managing director of BVB, Maren Schulze from Madaster, Talke Schaffrannek from BASF, and Jürgen Ephan, managing director at Remondis. This development shows how diverse the circular economy has become – and how many industries are searching for circular solutions.

New episodes are released (in German) every two weeks on all popular platforms. Anyone who wants to share the podcast content can do so very easily: listen, recommend it to others, and share or like the accompanying social media posts. Every bit of encouragement helps to raise awareness of circular economy issues and strengthen dialogue within the network.
