What Causes Food Waste in the Restaurant Industry?

In order to find ways to reduce food waste, it’s important to look at the causes first

Unlike household waste, one of the primary causes of food waste in restaurants is producing too much food. To ensure they don’t run out of popular dishes during busy times, many restaurants prepare more food than necessary. 

While having more food produced can keep customers satisfied, it often results in surplus, unsold food. Almost every food and agriculture organization agrees that generous portion sizes, another common practice, can also contribute to waste when customers can’t finish their meals. 

Finding solutions to food waste starts with better management approaches

When focusing on reducing wasted food, restaurants can analyze customer demand patterns, track food waste, and adjust their food production accordingly, striving for a balance between meeting customer expectations and minimizing waste. However, that’s not the only thing that causes food waste in the restaurant industry.

  • Menu Changes and Food Spoilage: Frequent changes to a restaurant’s menu can lead to the disposal of ingredients that are no longer needed. As seasonal dishes give way to new offerings, unused ingredients from previous menus can go to waste. 
  • Consumer Behavior and Inadequate Storage: Customer behavior also plays a role in food waste. Uneaten portions, dietary restrictions, and shifting preferences can lead to unfinished meals, contributing to restaurant food waste. 
  • Expiration Dates and Inefficient Practices: Restaurants sometimes discard food prematurely due to misinterpreting or ignoring expiration dates. Inefficient kitchen practices, such as inadequate training or suboptimal processes, can also lead to mistakes and wasted ingredients. 
  • Supplier Practices and Buffet Services: Supplier-related challenges, such as inaccurate orders or low-quality products, can contribute to food wasted in restaurants. Additionally, buffet-style and self-service restaurants may witness more leftover food, as customers tend to take more than they can consume. 

How to Reduce Food Waste in Restaurants?

Minimizing food waste is a challenge that the restaurant industry has grappled with for years. It’s not just about the economic impact, although that’s significant; it’s also about our responsibility to the environment and the ethical imperative to feed the hungry.

    • Cleaning Supplies: Empty containers from cleaning agents, used sponges, and so on.

    4. Energy Waste:

    • Excessive Heating/Cooling: Improper use of HVAC systems or lack of proper insulation.
    • Wasteful Lighting: Using non-energy-efficient lighting or keeping lights on unnecessarily.
    • Inefficient Appliances: Using older appliances that consume more power than newer, energy-efficient ones.

    5. Water Waste:

    • Leaky Faucets: Can lead to substantial water waste over time.
    • Excessive Dishwashing: Not optimizing the dishwashing process can lead to wasted water.

    Minimizing food waste in the food industry is crucial for environmental sustainability, cost savings, and ethical reasons. Various strategies can be employed across the supply chain, from food producers to human consumption, to curb food wastage. Here are some effective measures:

    1. Inventory Management:

    • Track and Monitor: Use inventory management software to monitor food usage, expiration dates, and stock levels.
    • FIFO (First In, First Out): Ensure that older stock is used before newer stock to reduce spoilage.

    2. Food Storage:

    • Optimal Storage: Store products at the right temperature and conditions to maximize shelf life.
    • Vacuum Sealing: Use vacuum sealing to extend the life of certain foods.
    • Regular Inspection: Regularly check storage areas for signs of spoilage or pest activity.

    3. Menu Planning and Portion Control:

    • Flexible Menus: Use menus that can be adjusted based on available ingredients.
    • Smaller Portions: Offer smaller portion sizes to give customers more choices and reduce plate waste.
    • Batch Cooking: Prepare food in smaller batches more frequently to avoid overproduction.

    4. Employee Training:

    • Waste Awareness: Train staff on the importance of waste reduction and provide guidelines.
    • Efficient Prep: Teach chefs and kitchen staff efficient food preparation techniques to minimize waste.

    5. Donations and Partnerships:

    • Donate Excess: Collaborate with local charities or food banks to donate unsold, but still edible, food.
    • Farmers and Suppliers: Work closely with suppliers and farmers to streamline orders and reduce surplus.

    Zero waste restaurants aim to operate without sending any trash to landfills. They implement sustainable practices throughout the entirety of their operations, from sourcing to serving. Here’s how zero waste restaurants typically work:

    1. Sourcing and Procurement:

    • Local and Seasonal Ingredients: Source ingredients locally and seasonally to reduce the environmental impact of transportation and storage.
    • Bulk Purchasing: Buy ingredients in bulk to reduce packaging waste.
    • Direct Relationships with Suppliers: Collaborate with suppliers who share the same zero-waste philosophy and can deliver products in reusable containers or packaging.

    2. Menu Design:

    • Dynamic Menus: Menus change based on the availability of seasonal and local ingredients.
    • Whole Ingredient Cooking: Utilize as much of an ingredient as possible (e.g., using carrot tops to make pesto).

    3. Food Preparation and Storage:

    • Reduce Overproduction: Cook in small batches and adjust based on demand.
    • Efficient Storage: Use storage techniques and equipment that reduce the need for single-use plastics (e.g., beeswax wraps, glass containers).

    4. Serve and Dine:

    • Reusable Serve-ware: Use reusable plates, glasses, cutlery, and napkins.
    • Avoid Single-Use Items: No plastic straws, stirrers, or disposable napkins. If needed, provide compostable or reusable alternatives.
    • Portion Control: Serve reasonable portion sizes to reduce plate waste.

    5. Waste Management:

    • Composting: All organic waste, like food scraps, is composted.
    • Recycling: Ensure proper segregation and recycling of materials.
    • On-site Treatment: Some restaurants have on-site systems, like biodigesters, to handle organic waste.

    6. Water and Energy Efficiency:

    • Use water-saving appliances and fixtures.
    • Opt for energy-efficient kitchen equipment and lighting.
