Even though thousands of people suffer from hunger each day, there are people that simply throw away their food, imposing serious environmental, social and economic consequences. Food waste concept, however, is not as strictly defined as it varies from research to research. The classification itself can be specific to certain regions and cultures, and it can even be affected by the eating habits of the researchers. This review paper aims to unify the theoretical knowledge of food wasting with examples from actual research, evaluating data from the perspective of eating habits and finding motives for such an action, such as family and friends’ influence, incomes, lifestyle, religion, mass media etc. Previously done studies show that people are less concerned about reducing food wastage when it comes to environmental and social problems, but are the most motivated if they see a real opportunity to save money.

Food rescue has emerged as a promising approach to address the interrelated issues of food insecurity and food waste. According to the food waste hierarchy, the next best strategy after food waste prevention is to donate surplus food for human consumption. However, while some countries have well-established networks of charities and government support to promote surplus food donation and food rescue in most developing countries is often less structured and smaller in scale. To gain insights into the current landscape of food rescue, this study thoroughly examined existing food rescue operations and systems, mainly from the UK, Singapore, Malaysia, India, and the Philippines. The study also analysed several countries' food rescue policy environments to understand how an enabling environment can be created. A particular focus was set on food safety being a critical consideration when rescuing and donating surplus food. Simplified food safety guidelines, staff training, and adequate storage and transportation facilities are crucial to food safety. Effective partnerships between food rescue organizations, food businesses, government agencies, and other stakeholders are also critical to the success of food rescue efforts. The study found a need to develop such partnerships in developing countries, where they may be less established than in the Global North. To facilitate the development of an enabling environment for food rescue in low- and middle-income countries (LMICs), the study developed a set of templates, including relevant food safety guidelines, partnership contracts, and policy templates. These resources can serve as valuable tools for stakeholders in LMICs to promote and enhance food rescue efforts that can help address food insecurity and reduce food waste.
