The food industry faces increasing pressure to adopt sustainable practices, reduce waste, and develop environmentally friendly products. In this shifting landscape, student competitions have become a critical monitor for emerging trends and a testing ground for practical solutions. Recently, a team from the University of Szeged in Hungary demonstrated exactly how academic knowledge can be applied to real-world sustainability challenges by winning the national round of the Ecotrophelia competition with an innovative, circular economy-based biscuit.

The Ecotrophelia Competition as a Monitor for Industry Trends
Ecotrophelia is an international student competition specifically designed to promote sustainable, market-ready food innovation. It challenges university students across Europe to design, develop, and pitch an eco-friendly food or drink product. The competition serves as an effective monitor for the food industry, highlighting what the next generation of food engineers and scientists deem commercially viable and environmentally necessary.
In Hungary, the national final is jointly coordinated by Campden BRI Magyarország—a leading food industry research, development, and innovation organization—and the National Innovation Agency. This backing ensures that the projects evaluated are not merely academic exercises, but rather serious product concepts that align with current market demands and green transition goals. The national stage brings together the country’s most promising student teams, creating a highly competitive environment that pushes participants to refine their ideas to professional standards.
Applying Circular Economy Principles to Food Product Development
The winning team from the University of Szeged, named Fruit-ReFormers, built their project around a foundational question: how can the principles of the circular economy be translated into a palatable, high-value food product that actively reduces industrial waste?
Circular economy in food science involves designing products that reuse by-products, extending the lifecycle of materials, and minimizing environmental impact. The Fruit-ReFormers—comprising students Dorka Lukovszki, Botond Dezső, and Benjámin Jancsó from the Faculty of Engineering—identified two major waste streams: spent coffee grounds from coffee shops and fruit fiber leftover from industrial juicing processes.
Instead of allowing these by-products to be discarded, the team engineered a cream-filled biscuit they named PeelPresso. The circular approach shaped the entire product architecture. Spent coffee grounds provided a distinct flavor profile suitable for the cream filling, while the leftover fruit fiber was creatively incorporated directly into the biscuit dough. This dual-use strategy resulted in a commercially viable product that directly addresses consumer demand for sustainable goods without sacrificing taste or texture.
The Laboratory Process: Balancing Taste and Sustainability
Developing a product that is both sustainable and enjoyable to eat requires rigorous laboratory testing. Repurposing spent coffee grounds and fruit fibers presents distinct technical challenges. Spent grounds can be bitter and gritty if not processed correctly, while adding fruit fiber to dough alters its rheology, potentially affecting baking times, structural integrity, and mouthfeel.
The team spent months working in the laboratory to find the optimal balance. Their goal was to ensure the sustainability aspect of the product enhanced, rather than detracted from, the consumer experience. This involved extensive trial and error with ingredient ratios, baking temperatures, and flavor pairings.
Crucially, this innovation was not developed in a vacuum. The students worked under the guidance of their teacher and mentor, Dr. Erzsébet Illés. They also leveraged specialized faculty expertise: Dóra Csercsics provided critical insights into confectionery technology that helped bring the physical product to life, and Edina Lendvai offered valuable advice on designing and executing the consumer questionnaire survey. This collaborative approach between students and experienced faculty is a hallmark of effective engineering education.
Overcoming Development Hurdles
As noted by team captain Botond Dezső, the idea emerged organically during their research into what remains in coffee after brewing. The transition from a conceptual idea to a competition-ready product required them to navigate food safety regulations, nutritional profiling, and sensory evaluation. The months of dedicated lab work highlight the reality of food innovation: it is a methodical, data-driven process that requires patience and precision.

Business Planning and Pitching to the Expert Jury
Ecotrophelia evaluates more than just the food product itself. The multi-stage competition tests the comprehensive skill sets of student teams, requiring them to excel in product development, business planning, and live presentations.
The Fruit-ReFormers had to construct a robust business case for PeelPresso. This included defining their target market, establishing a pricing strategy, calculating production costs, and detailing the environmental impact metrics of their circular economy approach. They then had to pitch this business plan and provide live tastings to an expert jury comprising food industry professionals, investors, and innovation specialists.
This holistic evaluation process ensures that winning products have a realistic chance of succeeding in the actual marketplace. For the University of Szeged team, their ability to clearly articulate the commercial viability of their green innovation was just as important as the biscuit’s flavor profile in securing the national title.
Academic Excellence at the University of Szeged Faculty of Engineering
The victory of the Fruit-ReFormers holds significant meaning for the University of Szeged. It marked the first time in the history of the institution’s Faculty of Engineering that a student team won the national Ecotrophelia final and qualified for the European stage.
Prof. Dr. József Sárosi, Dean of the Faculty of Engineering, emphasized that this historic achievement validates the quality of the food engineering and technology education provided at the university. It demonstrates that the curriculum ranks among the very best in Hungary. Prospective students and industry professionals alike can monitor the success of such teams as a reliable indicator of an institution’s commitment to practice-oriented, innovation-driven education.
The win reinforces the idea that modern engineering education must extend beyond theoretical lectures. By providing access to specialized laboratories and fostering close mentorship relationships, the University of Szeged equips students with the practical skills necessary to lead sustainability initiatives in the food sector.

Preparing for the European Final at SIAL Paris
By winning the national competition, the Fruit-ReFormers have earned the right to represent Hungary at the Ecotrophelia Europe final. This prestigious event is scheduled for October 18–19, 2026, and will take place at SIAL Paris, widely recognized as one of the world’s leading food industry trade shows.
Competing at SIAL Paris provides an unparalleled opportunity for the student team. They will present their innovation to an international audience of food industry executives, investors, and media. The stakes are high, and the competition will be fierce, featuring the top student teams from across Europe. In the weeks leading up to the event, the team will focus on refining every detail of their product, business plan, and presentation to ensure they can effectively compete on this larger stage.
Actionable Advice for Aspiring Food Innovators
The success of the University of Szeged team offers several practical lessons for other students and aspiring entrepreneurs looking to drive innovation in the food sector:
- Identify Real Waste Streams: Start by looking at existing industrial processes and identifying where valuable by-products are being lost. Spent coffee grounds and fruit pomace are abundant, underutilized resources.
- Prioritize Consumer Experience: Sustainability alone does not sell a product. The eating experience must be the primary focus during laboratory development to ensure market acceptance.
- Leverage Academic Mentorship: Utilize the diverse expertise available within a university faculty. Combining knowledge in food chemistry, confectionery technology, and market research creates a stronger, more resilient product concept.
- Build a Comprehensive Business Case: Technical innovation must be paired with sound business logic. Understanding production costs, target demographics, and environmental impact metrics is essential for pitching to expert juries or investors.
