How to reduce food waste in the food service industry
Reducing the food waste in the foodservice industry is one of the most pressing challenges for the sector. Food waste in restaurants in particular is a problem of enormous proportions.
The term “food waste” refers to any food intended for human consumption that, for various reasons, is either lost or thrown away. According to the FAO (Food and Agriculture Organization of the United Nations), every year about one third of the food produced for human consumption goes to waste, for a total of 1.3 billion tonnes.
Waste occurs at all levels of the food supply chain: from agricultural production to transport, during the processing of raw materials, in the distribution phase up until the consumption. Specifically, we define food losses the products that are thrown away during production, harvesting, and initial processing; whereas food waste refers to food wasted on sale and on consumption at home or outside the home.
In this article, we will focus on food waste in foodservice, i.e. all the food products that, despite still being suitable for human consumption, are rejected or thrown away during preparation, serving or consumption in restaurants, canteens and other foodservice facilities.
The impact of food waste in restaurants is significant: it leads to financial losses, social implications and environmental damage due to CO₂ emissions, water waste and the unnecessary exploitation of many other natural resources used in food production.
The cost of food waste in a restaurant can have a significant impact on the profitability of the business. According to some estimates, food waste in restaurants can account for up to 10-15% of the total cost of ingredients, which means thousands of euros lost on products that were bought but never actually served.

In this context, companies such as Firex, which specializes in cooking and food-prep solutions, provide tech solutions that help reduce waste in the foodservice industry. Automated cooking systems, precise serving size control, and streamlined processes help optimize the use of raw materials, reducing waste and increasing the overall efficiency.
Food waste in restaurants: figures and causes
As we saw, food waste is something that affects the whole production chain, with the highest levels recorded in the very last stages, especially the consumption. In fact, according to data from the Waste Watcher 2025 survey, weekly domestic waste in Italy amounts to 617.9 grams per person. However, a significant part of the waste also comes from restaurants and catering services, with each person estimated to waste around 12 kg of food per year.
According to the FAO, around 20% of food waste in Italy occurs in the foodservice industry, where around 4 million tonnes of food are thrown away every year.
The organized catering sector processes 3 million tonnes of food, but according to data provided by Banco Alimentare and Caritas, as much as 210,000 tonnes of it are surplus and only 12% of this (around 25,000 tonnes) is actually reused. [Source: www.salute.gov.it ]
The main causes of food waste in restaurants can be found in:
- Incorrect forecasts, many restaurants prepare more food than necessary to avoid running out during service. However, inaccurate estimates of the number of customers often lead to a surplus that ends up in the trash.
- Large portions, oversized dishes may overwhelm customers’ appetites, and leftover food must then be thrown away.
- Prepping errors, dishes cooked with the wrong ingredients or cooked incorrectly must be re-made or thrown away.
- Poop menu planning, an extensive menu requires a wide variety of ingredients, which may not all be used before they go off. In addition, poor planning can lead to a large amount of leftovers that are often not reused.
- Ineffective stock management, poor food rotation can lead to spoiled ingredients.
- Poor staff training,staff are not always taught to reduce waste: inaccurate cutting, excessive use of ingredients or lack of attention in preserving can increase waste.
- Restrictive regulations, in some cases, laws prevent the reuse of unserved food or the donation of leftovers, forcing restaurateurs to throw away food that is still good.
Where does wasted food go
A frequently asked question is: where does wasted food from restaurants go? Well, the truth is, it may vary depending on local regulations, the owner’s sensitivity and the presence of recovery networks. In general, the main options are:
- Food donations: many restaurants collaborate with organizations such as the Food Bank, Caritas or local associations to donate food that has not been served but is still fit for consumption.
- Composting: organic waste can be turned into compost, reducing environmental impact and contributing to soil fertility.
- Disposal in waste: unfortunately, a significant amount of food still ends up in general waste, with high economic and environmental costs.
- Energy recovery: in some cases, food waste is used to produce biogas or energy through anaerobic digestion plants.
Promoting more conscious and responsible management of unsold food is a crucial step towards more sustainable food service.
How to reduce food waste in restaurants
Successful restaurant management that fights food waste is not only an ethical choice, but also a winning strategy from both an economic and environmental perspective. The commitment to sustainability falls within a broader international context dictated by the Sustainable Development Goals of Agenda 2030, an action program for people, the planet and prosperity, signed in 2015 by the 193 member countries of the UN. Reducing food waste in the foodservice industry is at the heart of Target 12, which aims to ensure sustainable consumption and production models. Specific actions in the Horeca sector can contribute significantly to halving global food waste, as per target 12.3, and reducing the environmental impact. This includes implementing innovative technologies in order to make the production process more sustainable and environmentally friendly (Target 9).

Restaurant owners can take several actions to manage waste in their business and reduce it at all stages of service:
- Menu planing: creating seasonal and flexible menus makes it possible to use the same ingredients for multiple dishes, reducing the risk of surplus.
- Portion control: offering calibrated portions or the option to choose between different dish sizes allows customers to select the amount of food they can actually eat, avoiding leftovers.
- Staff training: educating chefs and operators on the efficient management of ingredients and proper food storage is essential.
- Leftover management: to recover unserved food, you can offer customers doggy bags or partner with organizations such as the Food Bank to reduce waste and help those in need.
- Waste monitoring: keeping track of what is thrown away helps to identify critical areas and take targeted action.
Technology plays an increasingly central role in combating food waste in restaurants. Modern equipment helps streamline the processes, improve the food preservation, and reduce human error.
Companies such as Firex, for example, offer professional cooking and food prepping solutions that help with:
