Speaker

Dr. Stephan Kothrade
Member of the Executive Board and Chief Technology Officer
BASF SE
Lecture information
Stephan Kothrade’s keynote outlines how circularity is becoming technically feasible at industrial scale, from recycled and renewable feedstocks to concrete examples such as loopamid® in textiles or solvent‑based PA6 recycling in the automotive sector. These innovations show what is already possible – but they also reveal a gap: despite progress, the green transformation is not moving fast enough. Clear, coherent regulation, technology‑neutral rules and demand‑pull mechanisms are needed to make circular solutions economically viable and scalable. The presentation makes the case that Europe can strengthen its resilience and competitiveness, if policymakers help create the conditions to accelerate circularity across industries.

Session: Opening & Keynotes
Language: English
Speaker

Prof. Dr. Dr. h.c. Christoph M. Schmidt
President
RWI - Leibniz Institute for Economic Research
Lecture information
Transforming the economy to a circular economy (CE) requires an encompassing digital transformation. In particular, applications of artificial intelligence (AI) can serve as enablers of CE applications. To this end, an effective AI policy needs, first, to be formulated as a European endeavor: It needs to reduce technological dependencies, but without compromising openness and competition. Second, the provision of a high-performance computation infrastructure is indispensable for the training of sufficiently powerful AI models. Third, access to high-quality data is a key prerequisite of the further development of specialized AI applications, requiring a lean and business-friendly regulation and the establishment of trustworthy approaches to data sharing, especially of industry data.

Thomas Krämer
Director Asia | Pacific
WIPOTEC GmbH
Lecture information
What if every product could tell its own story – from the origin of its materials to its reuse and/or recycling? This talk demonstrates how product marking and digital transparency become key enablers of the circular economy. Starting from the limits of the linear economy (Take–Make–Waste), it explains the shift toward data-driven, circular systems. The focus is on digital product markings and QR codes as the foundation for traceability, Digital Product Passports, and the implementation of regulatory requirements such as PPWR and ESPR. Practical examples illustrate how products become part of a resource-efficient digital ecosystem – and how knowledge of existing processes and development possibilities, combined with imagination, drives real innovation.

Circular economy – design requirements for reusable transit packagings
Format: Lecture
Session: Product Lifespan: Reuse, Repair, Refurbish
Language: English
Speakers

Walter Ahn
Founder
WASTO-PAC GmbH
Lecture information
EU’s PPWR is a key driver for reducing oneway (plastic) packaging and forces companies to think about reusable packaging. But the devil is in the detail as today’s oneway design is often not ideal at all for multiway purposes as suddenly reverse logistics, sorting, inspection, cleaning and repair needs to be considered.
We will address these topics as we are offering such services already long before PPWR and the term ’sustainability‘ became a trend.

Hydrometallurgical battery recycling at industrial scale:
What really matters for reliable, high-recovery and future-proof operations
Format: Lecture
Session: Recycling of resources
Language: English
Speaker

Dr. Michel Siemon
CEO
Primobius
Lecture information
For battery manufacturers, recycling companies, and automotive OEMs seeking to close material loops, lithium-ion battery recycling is no longer a question of technical feasibility. The challenge is how to operate plants that perform efficiently, responsibly and reliably while ensuring long-term economic viability.
As battery technologies evolve, facilities must process varying material compositions across chemistries such as NMC, LCO and LFP while achieving high recovery rates, battery-grade quality and stable throughput.
The presentation illustrates how the combination of mechanical pre-treatment through wet shredding and hydrometallurgical refining enables efficient metal recovery while reducing emissions, residues and water consumption. It shows how Primobius recycling processes support responsible resource recovery and stable plant operation.

Unlocking Low‑Carbon Construction: Ambition, Barriers, and the Case for Scaling Iron Silicate
Format: Lecture
Session: Recycling of resources
Language: English
Speaker

Inge Hofkens
COO Multimetal Recycling
Aurubis AG
Lecture information
Europe has committed to climate neutrality by 2050 – and construction must deliver. Yet a paradox persists: proven, low-CO₂ materials struggle to scale due to fragmented regulation. Using iron silicate from Aurubis as a case study, this talk shows how a safe, industrially available mineral can reduce concrete’s footprint by around 10% and save thousands of tons of CO₂ in large projects. To unlock such potential, Europe needs harmonised, science-based rules that enable circular materials to move from ambition to implementation.

Circular Aromatics from MSPW Sorting Residues: Pyrolysis Char as an Alternative Reforming Agent – Lab-to-Demo Scale
Aromatics are foundational to Europe’s sustainable plastics value chain, underpinning packaging, fibers, and engineering polymers. Securing low carbon supplies of BTX (Benzene, Toluene and Xylene) is therefore strategic: European demand is on the order of 15 Mt/y for BTX. Chemical recycling via pyrolysis can address this need by converting yet non-recyclable plastic waste streams into high-value hydrocarbons while reducing contaminants. The Pyromat technology developed at Fraunhofer UMSICHT employs pyrolysis char – the solid by-product of the initial pyrolysis step – as an alternative reforming/upgrading agent, promoting aromatic formation and lowering heteroatom contents in a single process.
The process demonstrates robust removal performance for halogens and metals – including chlorine, bromine, aluminum, phosphorus, and other heteroatom species – achieving thresholds compatible with drop-in petrochemical processing

Lecture information
Digital ecosystems – including data spaces – unite different actors under a common governance frameworks towards fulfilling a shared value proposition with the promise, to be faster, more cost efficient, and more productive than other forms of coordination.
Invariably, digital ecosystems build on the sharing of data as the first step to be able to provide value add services based on this shared data. Conceptually and technically, this may be realized either in the form of a more centralized (data) platform or a more decentralized data space. [548]
This lecture compares the two options and provides clear guidance on several key determinants influencing such as decision.
