Food upcycling focusing on private households: the potential of food upcycling in rural areas

Introduction Given the increasing importance of sustainability and the high levels of food waste, this descriptive, quantitative study explored food upcycling as a potential strategy to reduce waste, focusing on rural households in Germany. Methods A survey of 228 participants (response rate of 66%) examined the acceptance of food upcycling practices for fruits and vegetables in different age groups. Results While awareness of food waste is high, practical engagement with food upcycling remains limited. Notably, 51% of respondents was unfamiliar with the term “food upcycling,” although some of them may already be unknowingly apply this practice. Only 6% reported frequent upcycling of fruits and vegetables, while 59 % never do so. Discussion Generational trends suggest that older consumers (baby boomers and the post-war generation) are more likely to engage in food upcycling and show greater willingness to adopt and promote it. Younger generations (Gen Z and Gen Y), despite higher familiarity with the term, exhibit more neutral behavior and lower commitment. The results highlight a need for targeted initiatives to bridge the gap between knowledge and practice, especially in rural areas. Future research should include urban comparisons and a greater focus on inter-generational differences to encourage and support broader adoption of sustainable practices like food upcycling.
