122:(FAO) defines food waste as food appropriate for human consumption being discarded. The FAO reported that around one-third of all food produced for human consumption (1.3 billion tons) is lost and wasted across the entire supply chain every year, with an estimated value of US$ 936 billion. The amount of FLW varies between countries and is influenced by factors such as level of income, urbanization, and economic growth. In less-developed countries, FLW occurs mainly in the post-harvest and processing stage, while in developed countries, a significant portion occurs in the consumption stage, driven mostly by consumer behavior, values, and attitudes. FLW has serious environmental, economic, poverty, and natural resource impacts, including contributing to greenhouse gas emissions and decreased availability of food for human consumption. FLW reduction initiatives could improve food prices, efficiency in the supply chain, and access to nutritious foods for vulnerable households.
137:. To support this, the EU Platform on Food Losses and Food Waste was established to help prevent food waste and share best practices. In order to reduce food waste, it's important to accurately account for it throughout the food supply chain. However, there is currently no standardized way to do this. The Joint Research Centre of the European Commission organized a workshop to discuss how to harmonize and improve food waste accounting methodologies. Experts identified several research gaps, such as the need for clear and consistent definitions and terminology, improved data quality, and identifying drivers of food waste. These improvements will help policymakers better design policies to reduce food waste.
309:. Too Good To Go is a mobile application that connects consumers with local food businesses that have surplus food at the end of the day, such as restaurants and grocery stores, and offers the surplus food at a discounted price to reduce food waste. The app enables consumers to browse and purchase surplus food from local businesses, reducing food waste while also saving money. The app is available in several countries and has been successful in reducing food waste while also increasing revenue for local businesses. Overall this app aims to benefit both the consumers and businesses, and it has a positive impact on reducing the amount of food waste.

tonnes is classified as food wastage. This is equivalent to 7% of the total solid food products acquired by homes, restaurants, and shops in
Catalonia, which is 34.9 kg per person per year. This amount of food wastage is enough to feed over 500,000 people for a year. Home kitchens are responsible for the majority of food wastage, around 58% (151,800 tonnes), followed by supermarkets and grocery stores (16%), bars and restaurants (12%), retail food sector (9%), institutional catering and restaurant services (4%), and municipal markets (1%).
175:. Restaurants often overproduce food, leading to a surplus of food that goes to waste. For example, set menus at restaurants do not offer choices for the sizes of portions which means consumers may occasionally acquire too much food which goes to waste. In market settings, the majority of food waste is a result of poor management and storage processes. Factors such as inadequate employee training, difficulties in sales forecasting, and duration of fresh products all contribute to food waste in Barcelona's markets.
282:. The goal is to live in a way that helps the environment and doesn't harm it. Including using natural resources wisely and not wasting them. Universities can play an important role in promoting this by teaching students and encouraging healthy habits that support sustainability. This can help create a generation of professionals who are committed to protecting the environment.

220:. Additionally, food production, transportation, and processing require energy, and when food is wasted, the energy used to produce it is also wasted.
