Circular economy (CE) is a model that is gaining significance in the context of sustainable development and environmental protection, focusing on minimizing waste generation and maximizing the use of available resources through recycling and extending product life cycles. The implementation of CE in various European Union countries demonstrates diverse approaches to resource management, waste production, and energy efficiency improvement. These differences primarily stem from varying strategies, national policies, levels of social awareness, and technological advancements. The article identifies the key challenges and barriers associated with CE implementation in selected countries—Poland, the Netherlands, and Romania—and highlights specific areas requiring improvement and adaptation. It emphasizes the critical role of aligning national policies with the EU guidelines, promoting ecological education, and investing in innovative technologies and solutions that support sustainable development. Additionally, it points to the need for developing appropriate waste management infrastructure and encouraging businesses and consumers to change habits and engage in pro-environmental actions.

Functional food plays an increasingly important role in shaping healthy dietary habits by integrating health-promoting components into consumers’ everyday diets and helping reduce food waste. Products developed using by-products and raw material streams from food processing can support the principles of the circular economy (CE) by improving resource efficiency and lowering the environmental footprint of the food system. In Poland, as in many countries worldwide, functional food is a rapidly growing category that can contribute to public health and serve as a driver of economic development. However, the excessive and scientifically unsupported use of the term “functional food” for marketing purposes may mislead consumers and weaken trust in this product group. From a CE perspective, transparent communication and informed consumer choices are essential, as they promote environmentally responsible behaviors and support sustainable production models. The aim of this study was to assess the level of knowledge about functional food among residents of Eastern Poland, which is a less industrialized and predominantly agricultural region. The analysis focused on awareness of health benefits, consumption frequency, consumer attitudes, and interest in educational initiatives promoting functional food within CE principles. The study also examined whether consumers associate functional food with sustainability-oriented practices. The findings offer insights for educational and marketing strategies grounded in scientific evidence and highlight the potential of functional food in building a sustainable, resource-efficient food system.
