Restaurant Food Waste Statistics

Understanding the magnitude of food waste in the restaurant industry is the first step toward creating effective solutions. Here’s a snapshot of the issue:

U.S. restaurants are responsible for 22 to 33 billion pounds of food waste annually. Combined with other institutions like schools and hospitals, the total soars to 29 to 44 billion pounds.
Research indicates that 4 to 10 percent of food purchased by restaurants never reaches the consumer, largely due to over-preparation, poor storage practices, and excessively large portion sizes.
On average, diners leave 17 percent of their meals uneaten, and 55 percent of these potential leftovers are discarded at the restaurant itself.
The industry sees about 18% of the overall food waste, equating to billions of pounds of food that could otherwise be used to feed the hungry, generate energy, or create compost, potentially saving up to $25 billion annually.
Approximately 40% of all food in the U.S. is wasted, with the commercial sector, including restaurants, contributing significantly to this figure.
A staggering 84.3% of unused food in restaurants ends up being thrown away, while a mere 1.4% is donated.
A single restaurant can produce between 25,000 to 75,000 pounds of food waste in a year.
Consumer preferences are shifting, with 55% considering a restaurant's effort to reduce food waste an important factor in their dining choices.
Food costs account for 28% to 35% of a restaurant's operating budget, with food waste costing up to 4.2% of total sales.

The waste percentage can be even higher in buffet-style establishments or restaurants with extensive menus, leading to significant financial and environmental repercussions.

Causes of Restaurant Food Waste

Food waste in restaurants is a multifaceted issue, with several underlying causes contributing to the problem. Understanding these causes is crucial for devising effective strategies to mitigate waste.

Here are the common reasons behind food waste in restaurants:

1. Overproduction:

Restaurants often prepare more food than needed to ensure they can meet customer demand, especially during peak hours. This leads to excess food that is not sold by the end of the day and cannot always be reused or stored for future use.

2. Portion Sizes:

Large portion sizes are a significant contributor to food waste. When portions are too big, customers often leave a considerable amount of food on their plates, which then becomes waste.

3. Menu Complexity:

A wide-ranging menu requires more ingredients, which increases the likelihood of food spoilage before it can be used. The complexity also makes it challenging to predict which dishes will be popular on any given day, leading to overpreparation of certain items.

4. Customer Preferences and Orders:

Customers often request modifications to dishes, which can lead to waste if the discarded ingredients cannot be repurposed. Additionally, incorrect orders, either from customer or staff error, often result in perfectly good food being discarded.

5. Improper Storage and Handling:

Food spoilage due to inadequate storage conditions or improper handling is a significant cause of waste. This includes not storing food at the right temperature, not following first-in, first-out (FIFO) procedures, or improperly preparing ingredients.

6. Supply Chain Inefficiencies:

A significant factor contributing to food waste is the complexity of the supply chain. When restaurants overorder or receive perishable goods nearing expiration, they face a surplus that often goes unused. Additionally, logistical challenges can result in delayed deliveries, leaving kitchens with less time to use ingredients before spoilage.

7. Lack of Awareness and Training:

Staff may not be adequately trained on how to minimize food waste or may not be aware of the environmental and economic impact of food waste. This can lead to careless practices, such as throwing away food that could have been repurposed or donated.

8. Regulatory and Safety Concerns:

Restaurants often cite food safety regulations as a reason for discarding food. While safety is paramount, there is sometimes a misunderstanding or overly cautious interpretation of these regulations, leading to unnecessary waste.

9. Inadequate Waste Tracking:

Without systems to track food waste, restaurants may not be aware of the extent of the issue or understand the specific areas where waste occurs. This lack of data makes it challenging to implement targeted waste reduction strategies.

10. Failure to Forecast Customer Demand:

Predicting customer preferences and the quantity of food needed can be challenging. When restaurants miscalculate demand, they often prepare too much food, leading to a surplus that eventually becomes waste.

11. Lack of Proper Inventory Management:

Efficient inventory management is crucial to preventing food waste. Restaurants that fail to track their inventory accurately are more likely to order and prepare more food than necessary, exacerbating waste issues.

Recognizing these causes is crucial for any restaurant aiming to minimize waste and enhance sustainability. As we explore solutions to these challenges, remember that reducing food waste in restaurants benefits not only the environment and society but also your bottom line.

3 Types of Food Waste in Restaurants

Understanding the different types of food waste in restaurants is the first step toward implementing effective waste reduction strategies. Here's a closer look at where most waste occurs:

1. Client Food Waste (CFW)

This refers to the leftover food customers don’t consume and leave behind on their plates. It can happen for various reasons, such as overestimating their appetite, ordering too much food, or simply not liking the taste of a dish. It can also result from customers’ inability to customize their orders to their preferences.

2. Kitchen Food Waste (KFW)

This is food that is prepared but not served to customers. It can include spoilage, overproduction, trimming scraps, and spills. Spoilage can occur due to improper storage or if food is past its prime. Overproduction can happen if customer demand is miscalculated or if ingredients are prepped in large quantities in anticipation of a rush that never materializes. Trimming scraps are the leftover pieces of food that are removed during prep work, such as vegetable peels and meat trimmings. Spills are simply accidents that happen in any kitchen.

3. Service Food Waste (SFW)

This type includes waste generated during the service to customers, including order mistakes, over-preparation of dishes, and uneaten extras. Buffets contribute significantly to this category, as customers and restaurants often overestimate consumption, resulting in considerable amounts of food that cannot be reused. Recognizing these patterns can help adjust preparation and serving practices to minimize waste.

By identifying the primary sources of waste in your restaurant, you can tailor your waste reduction efforts more effectively, ensuring that strategies are focused and impactful.

How to Track Food Waste in Restaurants

Efficiently managing restaurant food waste begins with understanding the extent and nature of the waste being produced. Tracking food waste involves recording the amounts and types of waste and identifying when and why it occurs.
