Currently, humanity is generating more than one billion tons of food waste, including packaging, biodegradable edible food scraps, fruits and vegetables, among others. Together, these items accumulate about one hundred and thirty-two (132) kilograms per capita and almost one-fifth (1/5) of all food available to consumers (Department of Energy, 2024). Out of the total food that was wasted in 2022, sixty per cent (60 %) was produced by private households, twenty-eight per cent (28 %) originated from food and beverage service providers including hotels, restaurants, pubs and cafes, and twelve percent (12 %) came from retail stores (UNEP, 2024).
Frequently, food items and their ingredients are wasted because of a decline in quality, due to contamination, overstocking and/or spoilage issues, as they are not consumed before their expiry date, resulting in their decay (Pearson et al., 2025). Notwithstanding, the preparers of food tend to over-produce perishable items that are uneaten by consumers. Such spoilt products and surplus food will usually end up in municipal landfills, resulting in negative repercussions for our fragile natural environments, bio diversities and ecosystems (EuroStat, 2023). In other words, the piling up of food waste is inevitably causing pollution and irreparable damage| including global greenhouse gas emissions (GHG) that can exacerbate climate change for our planet.
At the time of writing, food loss and waste are triggering eight to ten per cent (8–10 %) of annual (GHG) emissions and are taking up the equivalent of almost a third of the world’s agricultural land. The disposal, handling and accumulation of food waste is costing the global economy about USD 1 trillion (UNEP, 2024). Therefore, the reduction of food loss is critical to increase the efficiency of the globe’s food systems, to improve food security for every nation and its citizens, whilst decreasing production costs in the value chain.
In this light, the rationale of this contribution is to raise awareness on responsible food and beverage operations in the hospitality industry. Primarily, it identifies sustainable practices that are intended to reduce food loss and waste from the value chain through sustainable sourcing of food products, by implementing sound inventory management systems as well as by promoting ecofriendly behaviors during responsible food preparation and consumption practices. A thorough review of the extant literature suggests that, currently, there are just a few articles that shed light on responsible food and beverage operations (Oke et al., 2023, Yong et al., 2024), although a number of institutions and organizations are raising the agenda on sustainable food production behaviors among practitioners (EU, 2021, HOTREC, 2017).
Secondly, this article highlights the importance of sustainability accounting and reporting during each stage of food preparation, production and consumption (Huang et al., 2023, Lee et al., 2024, Lin et al., 2024). It clearly explains in a pragmatic manner how environmental, social and governance (ESG) accountability standards, like the ones formulated by Global Reporting Initiative (GRI), Sustainability Accounting Standards Board (SASB) and the Food Loss and Waste Accounting and Reporting Standard (FLW Standard) among others, could be applied in the hospitality industry context.
Therefore, the research objectives of this contribution are threefold: (i) It identifies and discusses about sustainable practices that hotels, restaurants and cafes can implement to minimize food loss and waste; (ii) It sheds light on different regulatory instruments including guiding principles and standards, that can be utilized for ESG accounting, disclosures, audit and assurance of food and beverage services, including those operated by hospitality practitioners; (iii) It advances a theoretical model that clearly summarizes different aspects related to ESG dimensions.
Hospitality businesses can implement a number of responsible practices. The very first step for them is to develop ‘sustainable’ menus. The restaurants’ menus can offer a choice of different portion sizes to satisfy the requirements of different customers. They may feature fewer items in their menus to operate their business with a reduced inventory of food products to decrease storage costs, minimize waste and spoilage. It is in the interest of restaurant owner-managers to procure fresh ingredients from local businesses including farmers, bakers, butchers, et cetera, to ensure that they are preparing good food for their valued customers. Local products including organic items like fruit and vegetables, will have a longer shelf life than imported ones.
The hospitality businesses ought to forge close relationships with dependable, local suppliers to implement just-in-time purchasing systems (Camilleri, 2015a; Camilleri, 2017a). There is scope for them to purchase regularly and in smaller quantities to reduce the probabilities of food spoilage and dehydration. They are expected to continuously monitor the expiration dates of their food items and ingredients to minimize waste and to respect relevant hygienic standards. Owner-managers may apply the first expired first out (FEFO) principles in their kitchens, to avoid any stock-outs. Moreover, they can use food tracking devices to identify the types of food waste they are generating.
Their monitoring and control of food waste should be carried out on a day-to-day basis, as it can lead to significant operational efficiencies and cost savings. Practitioners may keep a track record of their waste in a spreadsheet. They can measure the quantity of organic waste that is generated from their premises. They may include details like the dates (and times of events), which ingredients or recipes were wasted, the name of the employee(s) who was (or were) responsible for the waste, et cetera. Furthermore, practitioners can estimate the composition of their organic waste and identify whether it is derived from vegetables, bread/pasta, specific meats, etc. This will allow them to make adjustments in their food menus (if possible).
Such food trackers may also help the hospitality business to detect irresponsible behaviors in their kitchens and to minimize food waste from their properties. It may indicate that certain employees are not engaging in responsible food preparation behaviors. There is scope for hospitality businesses to train their human resources, at all levels, particularly new employees, on circular economy approaches [Camilleri, 2014). This way, they will be in a better position to improve their efficiencies in terms of reducing, reusing and recycling resources, and responsible waste disposal practices (Camilleri, 2019a; Camilleri, 2020). They have to be supported and educated on the best practices to ensure that they are improving the (economic) sustainability of their businesses’ food and beverage operations whilst minimizing their impact on the natural environment (Camilleri, 2015b; Camilleri, 2016a; Camilleri, 2017). Table 1 illustrates the responsible behaviors that can be implemented by hospitality businesses to reduce food loss and the generation of waste from their premises:
This research shed light on a number of laudable circular economy initiatives that were drawn from the hospitality industry. It also made reference to a sustainable enterprise that utilizes a sharing economy platform that links consumers with hospitality service providers. Mobile users can purchase surplus food from hotels, restaurants and cafes at a discount. At the same time, the app enables the businesses to make revenue out of their perishable food and to minimize their environmental footprint by reducing their waste. Moreover, it reported that businesses can benefit from tax deductions and credit systems, in different contexts, if they donate surplus (edible) food to charities and food banks. Alternatively, if the food is contaminated or decayed it may be accumulated and turned it into animal feed, compost or transformed into energy through methanation processes. The case studies indicated that the re-utilization of non-edible leftovers may be monetized if they are used for such secondary purposes.
Key Takeaways
The implementation and execution of the circular economy’s closed loop systems ought to be promoted through different marketing channels. Hotels and restaurants can use marketing communications through different media to raise awareness on how they are capable of generating less waste (Camilleri, 2016b). They should promote sustainable production and consumption behaviors through different media outlets, including traditional and digital channels (Camilleri & Costa, 2018; Camilleri, 2018a; 2018b; 2018c).
The hospitality businesses responsible initiatives can raise their profile among different stakeholders, including customers and suppliers, among others (Camilleri, 2015; 2018d). The customers will probably appreciate the hospitality businesses’ efforts to reduce their impact to the natural environment. Some of their sustainability measures are dependent on the active commitment of hotel clients and restaurant patrons. Therefore, it is very important for them to raise awareness about their waste prevention campaigns and on their environmental achievements so that they may feel part of the responsible initiatives. This way, they become key participants in the reduction of generated waste. Hence, businesses can educate customers about responsible consumption behaviors to help them in their endeavors to curb food loss and the generation of unnecessary waste [Camilleri & Ratten, 2020; Camilleri, 2019b). The food and beverage servers could engage in conversations with their clients to better understand their food requirements.
In a similar vein, this research suggests that the hospitality businesses ought to forge closer relationships with their suppliers including farmers and other retailers, to implement responsible inventory management systems and just-in-time purchasing. Suppliers must continuously be informed and updated on their procurement policies. Their ongoing communications may facilitate collaborative practices that may translate to positive outcomes, including the sourcing of better-quality products with extended lifecycles and longer expiry dates.
This contribution reported various preventative measures and recycling practices that may be taken on board by hospitality practitioners and their stakeholders, to reduce food waste and its detrimental effect on our natural environment and biospheres. There is scope for trade unions and industry associations in tourism and hospitality, to promote the responsible behaviors, among their members.
Notwithstanding, regulatory authorities and their policy makers can encourage hospitality practitioners to invest in environmentally friendly systems to minimize their food loss and waste. They can offer them financial incentives like tax deductions or exemptions when they donate surplus food. Alternatively, governments can support them by providing adequate infrastructures and resources including on-site composting facilities and/or methanization processes that are aimed to minimize the accumulation of food waste that finishes in landfills. Such responsible investments will ultimately result in a sustainable value chain in tourism cities, as they add value to the hospitality businesses, to the environment and to society, at large (Salonen & Camilleri, 2020; Camilleri, 2017b).
