How to Reduce Food Waste For a More Sustainable Business

Food waste is a significant global issue, and it's not just a concern for households. Restaurants, cafeterias, and other food-service establishments also generate a considerable amount of food waste, and it's a problem that needs to be addressed.

The Importance of Reducing Food Waste

Reducing food waste in a restaurant is critical for several reasons. First, it helps to reduce the environmental impact of food waste. When food waste ends up in a landfill, it releases methane gas, which is a potent greenhouse gas that contributes to climate change. According to the United Nations Food and Agriculture Organization, approximately 133 billion pounds of edible food is wasted every year. Food service businesses can have a huge impact on their carbon footprint and contribute to a more sustainable future by implementing strategies to reduce food waste.

Reducing food waste also makes sense financially. When restaurants waste food, they are wasting money. Wasted food can cost restaurants thousands of dollars each year, and have a significant impact on their bottom line. So not only can you reduce your carbon footprint and help the environment, but you can also improve your profitability.

Conduct a Food Waste Audit

Conducting a food waste audit is an effective way for restaurants to identify areas where they're generating the most waste and develop strategies to reduce it. A food waste audit involves analyzing the restaurant's waste stream to determine the types and amounts of food waste generated.

Step 1: Plan and Prepare

The first step in conducting a food waste audit is to plan and prepare for the audit. This includes setting goals and objectives for the audit, identifying the areas of the restaurant to be audited, and assembling the necessary tools and materials for the audit. The tools required for a food waste audit may include scales, gloves, bins, and waste tracking sheets.

Step 2: Collect Data

The next step is to collect data on the types and amounts of food waste generated in the restaurant. This can be done by weighing and recording the amount of food waste generated in each area of the restaurant, such as the kitchen, dining area, and bar. It's important to collect data over several days or even a week to get an accurate picture of the restaurant's food waste.

Step 3: Analyze the Data

After collecting the data, the next step is to analyze it to identify the areas where the restaurant is generating the most waste. This may include analyzing the types of food waste generated, such as spoiled or expired food, trimmings, or uneaten customer meals. The data can be compiled into a spreadsheet or waste tracking software to make it easier to analyze.

Step 4: Identify Opportunities for Improvement

Once the data has been analyzed, the next step is to identify opportunities for improvement. This may include developing strategies to reduce food waste in the areas where it is most commonly generated, such as through better inventory management practices, smaller portion sizes, or modifying menus based on seasonal availability. It's important to involve staff in this process to ensure that everyone is on board with the plan.

Strategies for Reducing Food Waste

Once you do your food waste audit and review your findings there are many strategies that you can implement to help reduce food waste at your business.

Offer to go boxes

We've all been guilty of wanting to try everything on the menu, and then not being able to finish our meal. Have eco-friendly takeout boxes on hand for customers to take home their leftovers. They'll appreciate having your delicious food again later, and won't have to feel guilty about being wasteful.

Inventory Management

One of the most effective strategies for reducing food waste in a restaurant kitchen is better inventory management. This involves keeping track of the ingredients that are used in the kitchen, and ensuring that the kitchen has only what it needs to prepare dishes. By monitoring inventory levels and adjusting orders accordingly, restaurants can reduce the risk of over-ordering and spoilage.

Menu Planning

Another effective strategy is menu planning. By designing a menu based on seasonal availability and customer demand, restaurants can ensure that they are using fresh ingredients and reducing the amount of waste generated. Offering daily specials based on the ingredients that are currently in season can also help to reduce waste.

Portion Control

Portion control is another important strategy for reducing food waste in a restaurant kitchen. If you notice a lot of food waste is coming from specific dishes, try reducing the portion size. By serving smaller portions, restaurants can reduce the amount of food that is left uneaten and discarded. Training kitchen staff to use appropriate portion sizes for each dish can help to ensure that the restaurant is not wasting food.

Proper Food Storage

Proper food storage is critical for reducing uncooked food waste in any industrial kitchen. This includes ensuring that perishable items are stored at the appropriate temperature, and that they are used before they spoil. Making sure you use dated labels and implementing a first-in, first-out (FIFO) system can help make sure that the oldest ingredients are used first to reduce the risk of spoilage.

Staff Training

Training kitchen staff on the importance of reducing food waste is essential for success in reducing food waste in a restaurant kitchen. Staff should be trained on proper food handling techniques. This should include how to get the most out of fresh ingredients when they're being prepped, storing ingredients at the correct temperature, and how to identify when an ingredient has gone bad. By training staff, restaurants can create a culture of sustainability and reduce the amount of food waste generated.

Donation Programs

Donation programs can also be effective in reducing food waste in a restaurant kitchen. By partnering with local food banks or shelters, restaurants can donate excess food that is still safe to eat. This not only helps to reduce food waste but is a great way to support your local community.


We hope you found our guide to reducing food waste to be helpful. By combining the listed strategies, including better inventory management, menu planning, portion control, proper food storage, staff training, and donation programs your restaurant or food service business can reduce its environmental impact, save money, support your local community and contribute to a more sustainable future.
