The EPSolutely project is driving forward sustainable solutions for Expanded Polystyrene (EPS) recycling in Austria, ensuring that insulation materials remain part of a closed-loop economy. As a company committed to innovation and environmental responsibility, our member Steinbacher Dämmstoffe GmbH plays a central role in the project.
To gain deeper insights into the challenges and successes of EPS recycling, we spoke with Roland Hebbel, CEO of Steinbacher, and Maximilian Bernard, Head of Research & Development. Their expertise sheds light on how EPS waste is processed, the importance of industry collaboration, and the long-term vision for EPS recycling in Austria and beyond.
How does Steinbacher overcome the challenges of processing EPS waste with varying degrees of contamination, especially from different construction sites?
Maximilian Bernard: In general, the quality of EPS residues collected from construction sites has been significantly better than expected. Contamination mainly comes from larger foreign particles, such as cans or PU foam. To address this, we use optical separation at the dumping table, along with sieves and separators. Additionally, the traceability of collected EPS bags to specific construction sites and professionals allows us to intervene when necessary. In cases of heavy contamination, we can provide additional training or, in extreme cases, charge for disposal costs to ensure compliance.
Based on your experience with the pilot project, what improvements or investments have been critical in maintaining the quality of recycled EPS insulation boards?
Maximilian Bernard: The pilot phase has provided valuable insights, leading to key adaptations. Internally, we made adjustments in raw material return processes, including shredders and silos. However, the biggest improvements came from logistics at the construction site level. The introduction of big bags—which replaced the initial PE bags—was a game-changer. These crane-movable bags allow for larger insulation boards to be placed directly inside, simplifying handling and keeping the material dry during storage.
How has the training of clients and partners who use the EPSolutely system impacted the overall quality of the recycled materials you receive?
Maximilian Bernard: The key to success is strong industry partnerships. By integrating client feedback early in the process, we were able to fine-tune logistics on construction sites. The best example of this is the big bag system, which emerged directly from industry collaboration. Good communication with our partners ensures that improvements are implemented quickly, leading to higher-quality recycling outcomes.
What role do you see Steinbacher playing in scaling up the circular economy for EPS in Austria beyond the pilot phase?
Maximilian Bernard: We see ourselves as both innovators and facilitators of a sustainable EPS recycling system. Our responsibility extends beyond our own regional area, as we actively collaborate with national and international EPS industry partners to create a viable nationwide solution. The pilot phase has provided a strong foundation, and we are now focused on expanding and refining the system further.
As CEO, how do you envision Steinbacher contributing to the broader adoption of circular economy principles within the EPS industry, particularly through projects like EPSolutely?
Roland Hebbel: Our products have always been designed for resource efficiency and climate protection. EPSolutely serves as a flagship initiative for the European EPS industry, proving that EPS can be effectively recycled in a closed-loop system. Steinbacher is proud to be part of this transformation and is ready to support similar initiatives in other countries, sharing our expertise and best practices.
What strategic value does participating in the EPSolutely project bring to Steinbacher's long-term sustainability and innovation goals?
Roland Hebbel: Steinbacher is fully committed to increasing the recycled content in our products over the next few years. Closing the material loop is the most sustainable way to achieve this. Alongside investments in renewable energy, EPSolutely is a core part of our sustainability and innovation strategy. We strongly believe that a well-structured recycling system will not only enhance EPS's environmental performance but also create a competitive advantage by positioning EPS as a uniquely sustainable insulation material.
How do you ensure the financial viability of investing in new recycling technologies and processes for EPS in your company?
Roland Hebbel: Sustainability is an investment in long-term market security. The decision to invest in new recycling technologies is not just about immediate financial returns—it is about ensuring that EPS remains compliant with future regulations and continues to be a preferred insulation material. The European Green Deal and other policy frameworks will shape the industry's future, and only companies that adapt early will remain competitive.
What role does collaboration between industry partners, such as Austrotherm and Sunpor, play in the success of the project from a leadership perspective?
Roland Hebbel: EPSolutely was initiated by GPH, the national EPS association, with Steinbacher, Austrotherm, and Sunpor leading the way. Strong industry-wide collaboration is what makes this project a success. Each company brings unique expertise and regional networks, ensuring effective implementation. By working together, we are creating a functioning, scalable recycling system—one that will protect the climate and support the circular economy for years to come.
Conclusion
The EPSolutely project is proving that EPS recycling can be efficient, scalable, and beneficial for both the environment and industry. Thanks to the commitment of leaders like Steinbacher, innovative solutions are being developed to integrate EPS waste back into the production cycle.
Through strategic investments, industry collaboration, and client engagement, Steinbacher is setting the standard for circular economy practices in EPS insulation. The lessons learned from this pilot phase will not only strengthen Austria’s national recycling framework but also inspire similar initiatives across Europe.
As the EPSolutely project moves forward, its impact on sustainability, resource efficiency, and climate protection will continue to grow, ensuring that EPS remains a key player in the future of sustainable construction and packaging.
