“…The availability of food at the school snack bar also increases food waste, which encourages schoolchildren to eat more than they can (Priefer, Jörissen, & Bräutigam, 2016). Schoolchildren waste less food if there is a positive atmosphere in the dining hall (Elnakib et al, 2021).…”

The research aims to identify the factors affecting food waste and waste generation in schools and, consequently, barriers to zero-waste food consumption based on a systematic review of literature for the period 2015-2022. The research employed qualitative methods: systematic literature review, analysis and synthesis, as well as the monographic method. The literature review examined 1702 research papers and the abstracts. Using a PRISMA 2020 flow diagram, 54 papers were selected from the ScienceDirect, Scopus and Google Scholar databases for an in-depth analysis. Based on the literature review, 8 groups of factors that affected the generation of food waste in schools in the consumption process were identified: demographical, political, school food policy, environmental, socio-economic, personal/human, physical/human and geographical. The factors identified and aggregated might provide a basis for further discussions on zero-waste food consumption and food waste reduction in schools, as well as specific actions to optimize school food consumption and promote effective food and food waste management.

“…The Internet and the school environment were most often indicated as the source of knowledge on food waste. Studies show that interventions and the implementation of educational programs aimed at increasing social awareness of the scale of the problem lead to a reduction in the scale of food waste [9,18]. Educational institutions around the world are working to implement an educational framework that integrates One Health and transdisciplinary competencies to improve sustainable food production and environmental management.…”

Background. Consumer behavior and food waste are crucial factors that contribute to global food in security. This study aimed to evaluate the knowledge of food safety and food waste young consumers in Poland have. The survey was conducted among young people aged 15 ÷ 29. The impact of education, place of residence and household residence on the knowledge of food safety and food waste was exam ined. The cross-sectional survey was carried out between September and December 2022, using the CAWI technique for data collection. The anonymity and confidentiality of data were ensured. Results and conclusion. The respondent group comprised 640 people. Significant differences were observed in the definition of food safety among groups with different levels of education. The vast ma jority of respondents were not familiar with or did not even hear of the WHO's "5 Keys to Safe Food" (68.1 %), the 2030 Agenda for Sustainable Development (86.3 %) or the concept of sustainable food (59.1 %). On the other hand, when it came to issues of food loss and waste, 86.5 % of respondents were familiar with these concepts. As many as 67.3 % of respondents admitted to throwing food away. The groups differed significantly both in terms of education and place of residence. Based on logistic regres sion, it was estimated that those living alone, those living in the city and those with secondary and higher education were more likely to pay attention to food waste. Based on the survey, it can be concluded that large-scale educational action is needed.

Sustainability Recommendations and Practices in School Feeding: A Systematic Review

et al. 2022

View full text Add to dashboard Cite

Considering the importance of schools for sustainable food offers and the formation of conscientious citizens on sustainability, this systematic review aimed to verify the recommendations on sustainability in school feeding policies and the sustainability practices adopted in schools. The research question that guided this study is “what are the recommendations on sustainability in school feeding policies and the sustainability practices adopted in schools?”. This systematic review was prepared according to PRISMA, and its checklist was registered in PROSPERO. Specific search strategies for Scopus, Web of Science, Pubmed, Lilacs, Google Scholar, and ProQuest Dissertations & Theses Global were developed. The included studies’ methodological quality was evaluated using the Meta-Analysis Statistical Assessment and Review Instrument (MASTARI). A total of 134 studies were selected for a full reading. Of these, 50 met the eligibility criteria and were included in the systematic review. Several sustainability practices were described. The most cited are school gardens and education activities for sustainability. However, actions carried out in food services were also mentioned, from the planning of menus and the purchase of raw materials (mainly local and organic foods, vegetarian/vegan menus) to the distribution of meals (reduction of organic and inorganic waste: composting, recycling, donating food, and portion sizes). Recommendations for purchasing sustainable food (organic, local, and seasonal), nutrition education focused on sustainability, and reducing food waste were frequent; this reinforces the need to stimulate managers’ view, in their most varied spheres, for the priority that should be given to this theme, so that education for sustainability is universally part of the curricula. The importance of education in enabling individuals to promote sustainable development is reaffirmed in Sustainable Development Goal 4 (SDG 4). The development of assessment instruments can help monitor the evolution of sustainable strategies at schools and the main barriers and potentialities related to their implementation.
