Research on cutting food waste in restaurants, hotels and other hospitality businesses has grown fast since 2020 and shows that circular practices work, but it concentrates on preventing, minimising and recycling waste and rarely explains what drives customers to take part. This review of 51 studies maps the field and sets a research agenda.
Key findings
- Research on circular food waste practices in hospitality is recent. Of 51 studies published between 2014 and August 2023, 48 (94.1%) appeared from 2020 onwards, mostly in Q1 journals (84.3%), with Sustainability (9) and British Food Journal (6) publishing the most (Cardenas et al., 2024).
- Circular practices reduce food waste and encourage sustainable customer behaviour. Practices such as smaller portions, menu planning, nudges, visual reminders, upcycled food, take-away of leftovers and food redistribution reduce food waste; one communication intervention cut food waste by 30% (Cardenas et al., 2024).
- Most research targets prevention, minimisation and recycling. Mapped onto the food waste hierarchy, the studies focus on preventing, minimising and recycling food waste, while reusing, recovery and disposal practices receive far less attention (Cardenas et al., 2024).
- Who wastes food in hospitality differs by age, income and other traits. Younger, lower-educated, higher-income, single and travelling customers tend to waste more food, while perceived behavioural control and social norms help customers reduce plate waste (Cardenas et al., 2024).
- Theory is used in only 37% of the studies. Nineteen of the 51 studies used a theory, most often the theory of planned behaviour (7 studies); the review calls for broader theories, more explanatory research and studies in less-developed countries (Cardenas et al., 2024).

Tables
Table 1. Examples of practices in the food waste hierarchy
| Sets of practices | Examples |
|---|---|
| 1. Prevention | Just-in-time ordering systems (Lefadola et al., 2018); menu planning (Wu and Teng, 2022); rethinking purchasing strategies (e.g., timing, food quantities, types of food) (Filimonau et al., 2019) |
| 2. Minimisation | Portion control (McGrath, 2021); reducing plate sizes (Papargyropoulou et al., 2019); limiting over preparing (Cicatiello and Franco, 2020); being aware of activities that can lead to ruined/unusable food (McGrath, 2021) |
| 3. Reusing | Practices related to being creative with existing ingredients before buying new ones (Reynolds et al., 2020) |
| 4. Recycling | Redistributing to charities (Giordano et al., 2020); secondary uses (Paltrinieri et al., 2022); pickling and preserving (Joardder, 2019) |
| 5. Recovery | Sensory testing (Wellton and Öström, 2022); refreshing vegetables (Lombardi and Costantino, 2021) |
| 6. Disposal | Life cycle analyses, regenerative disposal, composting (Soma, 2021) |
Table 5. Socio-demographic variables influencing food waste
| Variable | Study selection findings | Reference |
|---|---|---|
| Age | Older people tend to waste less food than younger people. | Gallagher et al., 2022; Pandey et al., 2023; Wang et al., 2021 |
| Education level | Individuals with a higher education level are more likely to waste less food. | Wang et al. (2021) |
| Income | Individuals who possess higher income tend to waste more food. | Goodman-Smith et al., 2020; Secondi et al., 2020 |
| Gender | Based on gender, individuals adopt different strategies to reduce food waste. | Gallagher et al., 2022; Pandey et al., 2023 |
| Relationship status | Single individuals are more likely to waste more food than people with married individuals. | Secondi et al., 2020; Wang et al., 2021 |
| National identity | National identity influences food waste behaviour. People tend to be less concerned about preventing food waste when travelling. | Gallagher et al., 2022; Grasso et al., 2023; Orea-Giner and Fusté-Forné, 2023; Wang et al., 2021 |
Some studies covered various socio-demographic variables and were listed in multiple columns.
Table 6. Challenges in research agenda themes to guide future studies
| Research agenda theme | Research challenges |
|---|---|
| Theme 1: Increase the scope of food waste research | Developing innovative study models to evaluate practices aimed at preventing food waste, to be applied and tested in diverse contexts. Conducting balanced comparative studies in both developed and less developed settings to ascertain the impact of circular practices on food waste reduction. Identifying context-specific factors that influence or impede food waste, thereby establishing a benchmark for comparative analyses with analogous countries. |
| Theme 2: Expanding the use of mediators and moderators | Developing research models incorporating theoretical or practical input from different disciplines to expand understanding of circular practices and food waste. Analysing the food waste system to identify circular practices utilised in addressing food waste. Determining the necessary parameters for implementing circular practices to mitigate food waste, thereby guiding the implementation of these practices to achieve optimal results. |
| Theme 3: Enhance the evaluation of strategies to mitigating food waste | Developing comprehensive study models, including actual implementation in hospitality contexts, to determine the relationship between circular practices and food waste. Retrieving the outcomes and insights from applying circular practices to reduce food waste to guide future applications and identify potential areas for improvement. Identifying the antecedents and consequences derived from the application of circular practices to assist the development of food waste reduction strategies. |
| Theme 4: Broadening the use of theories to conduct research | Undertaking comprehensive system wide studies using a flexible theoretical framework to better understand food waste and develop effective strategies to tackle it. To identify elements of the food waste hierarchy that present the greatest opportunities for substantive change. Examining apposite theories to explore inter-multi-cross-disciplinary elements of food waste behaviour within the food waste system. Developing measurement and well-founded theoretical frameworks that can be sued to predict and influence food waste behaviours in multiple levels of the food waste system and the food waste hierarchy. |

Several studies covered different aspects of the food waste hierarchy and were listed across multiple columns. The last theme is numbered (iii) in the article; it is theme (viii).
The question
The hospitality sector produces about a quarter of global food waste, much of it avoidable, and SDG 12.3 aims to halve retail and consumer food waste by 2030. Circular practices aim to prevent and reduce waste and keep food in use. We asked what research exists on circular practices regarding food waste in hospitality, what it covers, which practices and theories it uses, and what future research should address.
Implications
Practical implications
Hospitality managers can choose practices along the food waste hierarchy, tailor interventions to customers’ socio-demographic and psychosocial characteristics, communicate circular practices such as upcycled food and menu planning to customers, and build a culture of sustainability through committed leadership, which also cuts costs.
Theoretical implications
The review organises the evidence by the food waste hierarchy, shows where research is missing (reuse, recovery, disposal; less-developed countries; explanatory designs) and proposes a four-theme research agenda with mediators, moderators, theories and evaluation strategies.
Limitations and future research
- The search across nine databases may have missed relevant studies, including those not in English.
- Grey literature was excluded.
- The authors describe the review’s scope as concentrated in developed nations, which may limit its applicability to less-developed contexts.
Questions this paper answers
What are circular practices for food waste in hospitality?
Practices that prevent, minimise, reuse, recycle, recover or dispose of food waste, such as menu planning, portion control, creative use of ingredients, redistributing surplus food, and composting (Cardenas et al., 2024).
Do circular practices reduce food waste in restaurants and hotels?
Yes. A systematic review of 51 studies found that circular practices reduce food waste and encourage sustainable behaviour among customers (Cardenas et al., 2024).
Which customers waste more food when eating out?
The studies reviewed suggest that younger customers, those with less education, higher incomes, single people and tourists tend to waste more food (Cardenas et al., 2024).
What theories are used to study food waste in hospitality?
Only 37% of the 51 studies used a theory, most often the theory of planned behaviour; others include norm activation theory, social cognitive theory and institutional theory (Cardenas et al., 2024).
Key concepts
- Circular economy
- An economic model with a regenerative aim that keeps resources in use and prevents waste, rather than producing, using and discarding.
- Food waste hierarchy
- A ranking of food waste practices from most to least preferred: prevention, minimisation, reusing, recycling, recovery and disposal (European Commission, 2017).
- Plate waste
- Food served to customers that is left uneaten and thrown away.
- Systematic literature review
- A review that identifies, screens and synthesises all studies on a question through an explicit, reproducible search and selection procedure.
