Why Do Restaurants Waste Food: Insights and Solutions

Restaurant food waste is a pressing issue in the United States, with an astonishing 40% of food produced going to waste. This not only costs restaurant owners millions of dollars annually but also has significant environmental implications. However, there are practical measures that restaurateurs can adopt to diminish food waste while saving money. In this article, we will delve into some of these strategies. Let’s explore!

Restaurant Food Waste: What It Entails

Restaurant food waste encompasses edible food that remains unused or uneaten in commercial eateries. It differs from food scraps, which typically consist of inedible parts like fruit peels, bones, and shells. Restaurant food waste, on the other hand, involves fully prepared meals and perishable ingredients such as dairy, bread, and proteins that can no longer be utilized for their intended purpose.

Food waste in restaurants has become a growing concern globally due to its environmental impact. Each year, billions of kilograms of restaurant food are discarded, emitting methane and other harmful greenhouse gases as it decomposes in landfills. Beyond the environmental consequences, food waste also incurs high economic costs for restaurants, as it involves purchasing ingredients that ultimately go to waste.


Why Do Restaurants Discard Food?

There are various reasons why restaurants throw away food. Some common causes include:


Restaurants may prepare more food than necessary, resulting in excess that cannot be served to customers. Overestimating the required quantity or sudden changes in customer demand can lead to this situation.

Food Spoilage

Restaurants often use perishable ingredients such as meat, fish, dairy, and fresh produce. If these ingredients are not used within a specific timeframe, they spoil and must be discarded.

Health and Safety Regulations

Restaurants may be obligated to dispose of food for health and safety reasons. For instance, if Time/Temperature Control for Safety (TCS) food remains at room temperature for too long, it becomes unsafe to serve and must be discarded.

Food Left Uneaten by Customers

Restaurants are legally required to discard any uneaten food to mitigate contamination and health risks. Unfortunately, this often means perfectly good ingredients and meals end up in the trash, resulting in a significant waste of resources.

The reasons behind food wastage in restaurants are complex and extend beyond health regulations. Restaurants often aim to serve a specific number of meals per night, and any excess ingredients may be discarded instead of being used for future dishes. Additionally, many establishments hesitate to donate leftover food, fearing potential liability if someone falls ill after consumption.

Incorrect Orders

Incorrect orders must be discarded to avoid customers consuming unsafe or substandard food. Repurposing erroneous orders can be challenging due to the time and effort required to transform them into usable ingredients.

Customer Dissatisfaction

When patrons are displeased with their food, they often request it to be returned. In compliance with food safety regulations, any food served and returned cannot be reused due to potential health concerns.

Fast-paced Nature of Restaurant Work

Mistakes in the kitchen, such as over-ordering, excessive preparation for special events or menu items, inaccurate portioning, and improper storage, can result in surplus food being thrown away. In some cases, restaurants even discard perfectly safe-to-eat food because it doesn’t meet their standards in terms of appearance or texture.

Overall, the reasons for food wastage in restaurants are multifaceted and vary depending on the establishment and circumstances.

Different Types of Food Waste in Restaurants

Food waste in restaurants stems from several sources. Some common types of food waste include:

  1. Client Food Waste (CFW): This refers to the food left unconsumed by customers at restaurants. It includes uneaten portions on plates, half-eaten meals, and takeaway leftovers. CFW occurs when customers overestimate their portion needs, order more food than they can consume, or are unable to finish their meals. It is the most challenging type of food waste to manage since it falls beyond the control of the restaurant.

  2. Kitchen Food Waste (KFW): KFW comprises excess food that is prepared but not served. It typically consists of uneaten prepared meals, expired ingredients, and food trimmings. KFW often results from inaccurate forecasting, overproduction, or excessively large portion sizes.

  3. Buffet Leftover Waste: This refers to the food remaining unconsumed by customers at buffets. Buffet leftovers occur when customers take more food than they can eat, leave behind unfinished dishes, or fail to adhere to proper portion control.

How to Reduce Food Waste in Restaurants

Reducing food waste in restaurants is crucial not only for financial reasons but also for environmental sustainability. Here are 11 practical tips to help minimize food waste:

1. Buy Flawed Ingredients

Restaurants can reduce food waste by purchasing imperfect fruits and vegetables. These products are often cheaper because grocery stores typically do not display produce with blemishes, discoloration, or unusual shapes. By buying these items, restaurants can save money while still providing high-quality ingredients and preventing edible produce from ending up in landfills.

2. Cater to Preferences or Provide Multiple Portion Sizes

Portion sizes play a significant role in food waste. Some customers may not finish their entire meal, while others may desire larger portions. By proactively asking customers about their preferred serving sizes and accommodating their requests, restaurants can minimize food waste.

3. Repurpose and Multi-Use Edible Ingredients

Restaurants can repurpose and multi-use edible ingredients to reduce waste. For example:

  • Trimmings from cutting raw vegetables can be used for soups or stocks.
  • Bruised fruits and vegetables can be pureed for sauces.
  • Stale bread can be transformed into croutons or breadcrumbs.
  • Excess proteins like chicken and fish can be shredded for tacos.
  • Wilted greens can be salvaged for salads or pesto.

This approach reduces ingredient purchases, resulting in cost savings and reduced food waste.

4. Mindful Menu Planning

Efficient menu planning is key to reducing food waste in restaurants. Chefs can ensure that they purchase and utilize only necessary ingredients, avoiding over-purchasing or over-preparation. Menu planning also fosters menu balance, ensuring a variety of dishes while preventing excessive stocking of particular items. Chefs should consider the size and capacity of the kitchen, ingredient seasonality, customer preferences, and budget constraints to plan menus effectively.

5. Implement Discount Pricing

Offering discounts on specific menu items can prevent food waste. Discounts encourage customers to purchase items that have been around longer, helping to clear out stock before it spoils. Discounted menu items can also serve as promotional tools, with restaurant owners adjusting prices based on the speed of sales.

6. Foster Local Food Partnerships

Partnering with local farms and suppliers allows restaurants to access fresher ingredients without the need for long-distance transportation. This reduces food waste resulting from spoilage during transit and storage.

7. Embrace Composting

Composting is an effective method to reduce food waste in restaurants. It involves breaking down organic matter, including leftover food scraps, into nutrient-rich soil suitable for gardening or landscaping. By composting restaurant waste, establishments can minimize landfill waste and generate a valuable byproduct.

8. Encourage Employee Education and Empowerment

It is essential to educate restaurant workers about the significance of reducing food waste and how their actions contribute to this goal. Training should cover portion sizing, inventory management, proper storage techniques, and safe handling practices to ensure efficient food utilization with minimal waste.

9. Encourage Taking Home Leftovers

Encouraging customers to take home their leftover food can significantly reduce food waste. This benefits both the customer, who can enjoy a meal later, and the restaurant, which saves resources. Restaurants can provide containers or packages designed specifically for leftovers to facilitate safe storage without compromising food quality.

10. Donate Excess Food

Restaurants can donate their excess food to food banks, charities, and shelters. While there may be legal considerations, such donations effectively reduce waste and provide meals to those in need. Restaurants should ensure that donated food is stored, handled, and transported correctly to ensure its safety for consumption.

11. Utilize Restaurant Inventory Management Software

Implementing restaurant inventory management software can significantly reduce food waste. These solutions offer features that help operators manage stock effectively and identify areas to cut down on waste. Features like expiration date tracking, demand forecasting, automated order generation, payment system integration, and reporting can optimize resource management. Many inventory management systems also include threshold and alert capabilities, allowing operators to take action before food goes to waste, thereby saving time and money. By leveraging these features, restaurants can minimize waste, increase operational efficiency, and improve profitability.

Conclusion: Driving Sustainability in Restaurants

As the global population grows and resources become scarcer, reducing food waste becomes increasingly critical. In restaurants, food waste not only represents a financial loss but also contributes to environmental degradation and food insecurity. By adopting strategies such as meticulous inventory management, composting, and food donation programs, restaurants can play a pivotal role in creating a more sustainable and equitable food system. By taking proactive steps to combat food waste, restaurants contribute to a better future for everyone.
