How to Deal with Food Waste in Restaurants | 18 Strategies

The restaurant industry has been a major contributor to food waste, with estimates in previous years indicating that American restaurants produced 22-33 billion pounds of food waste annually, and a substantial portion of unused food in restaurants ended up being discarded.

The economic implications of this waste are considerable, not only in terms of the direct costs incurred by restaurants due to over-purchasing and inefficient use of ingredients but also in the broader context of environmental sustainability. Food waste contributes to greenhouse gas emissions and the inefficient use of resources like water, energy, and labor.

In 2023, efforts were underway to address this issue more systematically. The U.S. Department of Agriculture (USDA), Environmental Protection Agency (EPA), and Food and Drug Administration (FDA) released a national strategy aimed at reducing food loss and waste in the U.S. by 50% by 2030, highlighting the ongoing importance of this issue and the concerted efforts required to tackle it effectively.

Given this context, the necessity for restaurants to control food waste remains critical. Effective restaurant food waste management can lead to significant cost savings, improved sustainability, and enhanced brand reputation, particularly as consumers become increasingly environmentally conscious. Restaurants adopting strategies to avoid food waste can contribute to broader environmental goals while also improving their operational efficiency and profitability.

1. Conducting a Food Waste Audit

A food waste audit is a methodical process used by restaurants to identify and quantify the waste they produce. This approach involves tracking and recording all the food that gets thrown away within a specified period. The purpose of a food waste audit is to gain a clear understanding of where and why waste is occurring, enabling restaurants to take targeted actions to reduce it.

Steps to Conduct a Food Waste Audit

• Initial Assessment: Begin by collecting data on the types and amounts of waste generated. This can be done by keeping a log of all wasted food over a certain period, typically a week.
• Categorization: Classify the restaurant food waste into different categories such as pre-consumer (e.g., spoiled produce, trimmings) and post-consumer waste (e.g., leftovers from customers' plates).
• Analysis: Analyze the collected data to identify patterns and the most significant sources of waste.
• Action Plan: Develop strategies to address the identified issues, such as adjusting purchasing practices, changing menu items, or retraining staff.

2. Implementing FIFO in Inventory Management

The First In, First Out (FIFO) method is a widely used inventory management technique in the restaurant industry. It entails using or selling older stock before newer stock. This approach is crucial for managing perishables effectively and reducing waste due to spoilage.

Organizing Inventory Using FIFO

• Stock Organization: Arrange your inventory so that older items are in front or on top, making them more accessible.
• Staff Training: Educate your staff about the importance of FIFO and train them on how to properly organize and use stock based on arrival dates.
• Regular Checks: Regularly check inventory to ensure that older items are used first and to identify any items that are nearing their expiration dates.

3. Optimizing Portion Sizes

Optimizing portion sizes involves adjusting the amount of food served to customers in order to minimize leftovers and reduce waste. This strategy not only cuts down on waste but can also lead to cost savings and increased customer satisfaction.

Determining Optimal Portion Sizes

• Data Collection: Gather data on leftover food and customer feedback regarding portion sizes.
• Menu Adjustments: Based on the collected data, adjust the portion sizes of your dishes. This might mean reducing the size of some dishes or offering different portion options.
• Trial and Feedback: Implement the new portion sizes and closely monitor customer responses and waste levels. Continuously refine portion sizes based on ongoing feedback and waste audit results.

‍

4. Menu Design and Ingredient Overlap

Menu design and ingredient overlap involve strategically crafting a restaurant's menu to use similar ingredients across multiple dishes. This approach minimizes waste by ensuring that all purchased ingredients are utilized to their fullest potential.

Planning for Ingredient Overlap

• Identify Core Ingredients: Start by identifying ingredients that can be used in several dishes. These might include common vegetables, proteins, or grains.
• Menu Creativity: Develop recipes that incorporate these core ingredients in various ways. For example, a single type of vegetable could be used in a salad, a main dish, and a soup.
• Flexible Preparations: Design dishes that allow for flexible ingredient use, accommodating what's available or in surplus.
• Regular Review: Continuously evaluate your menu and make adjustments based on what ingredients are most frequently leftover or unused.

‍
