Food waste is a massive issue in the restaurant industry. In fact, up to 40% of food in restaurants ends up in the trash. That’s not just bad for your bottom line—it also has a serious environmental impact.

When food waste goes to landfill, it produces methane, a greenhouse gas that’s 25 times more potent than carbon dioxide. Plus, all the resources that went into producing, transporting, and preparing that food are wasted, too.

The good news? Reducing food waste is possible—and it starts with tracking it. A food waste log is a simple yet powerful tool to help restaurants understand where waste happens, take action, and save money while improving sustainability.

What is a restaurant waste log?

A restaurant waste log is a record-keeping tool used to track and measure food waste over time. It helps restaurants identify problem areas, adjust purchasing and prep habits, and ultimately reduce waste and costs.

A typical food waste log includes details such as:

• Type of food waste, such as spoiled produce, expired dairy, or overcooked meals
• Quantity of waste, measured in weight or volume
• Reason for waste, such as overproduction, spoilage, or preparation errors
• Time and date, tracking when waste occurs
• Method of disposal, such as landfill, composting, or donation

By keeping a detailed log, restaurants gain valuable insights into their waste patterns. This data can be used to implement targeted strategies—such as adjusting portion sizes, improving inventory management, or repurposing ingredients—to cut costs and improve sustainability.

What are the benefits of a restaurant waste log?

A restaurant waste log provides valuable insights that help businesses cut costs, reduce waste, and improve overall operations. By tracking food waste, restaurants can optimize their purchasing and preparation processes, enhance food safety, and boost restaurant efficiency.

Identifying patterns and trends

A waste log helps restaurants spot recurring waste patterns—whether it’s overordering produce, discarding large portions of uneaten meals, or frequently tossing expired ingredients. By recognizing these trends, businesses can adjust purchasing habits, portion sizes, and menu offerings to reduce waste at the source.

Setting goals and measuring progress

Tracking waste allows restaurants to set specific, measurable waste reduction goals. For example, a business might aim to reduce spoilage by 20% over three months by improving storage methods or rotating stock more efficiently. A waste log helps measure progress and fine-tune strategies over time.

Saving money

Food waste directly impacts profitability. Every discarded ingredient represents lost revenue, from purchasing costs to labor spent preparing food that never gets served. By analyzing waste data, restaurants can minimize overproduction, streamline inventory management, and reduce unnecessary expenses.

Improving sustainability

Reducing food waste isn’t just about cost savings—it’s also an essential part of running a sustainable restaurant. Food waste contributes to landfill overflow and greenhouse gas emissions. Implementing better waste management practices, like donating surplus food, composting scraps, or repurposing ingredients, helps minimize environmental impact while improving food safety.

Encouraging better habits

A waste log fosters awareness and accountability among kitchen staff. When employees actively track waste, they become more mindful of portioning, ingredient usage, and food handling. Over time, this promotes restaurant efficiency and a culture of waste reduction, making sustainability a daily habit rather than an afterthought.

How to Perform a Food Waste Audit with a Food Waste Log

A food waste audit helps restaurants track, analyze, and reduce waste systematically. By using a food waste log, you can pinpoint inefficiencies, improve purchasing decisions, and cut costs while enhancing sustainability.

Step #1 – Define your categories

Start by categorizing the types of food waste you’ll track. Common categories include:

• Pre-consumer waste – spoiled ingredients, kitchen scraps, overproduction
• Post-consumer waste – uneaten leftovers, plate waste
• Storage waste – expired or improperly stored food

Defining these categories ensures consistent data collection and helps maintain an accurate food safety record for compliance and operational improvements.

Step #2 – Set up your log

Create a structured food waste log, either digitally or on paper. Your log should include:

• Date and time
• Type of food waste
• Quantity (weight or volume)
• Reason for waste (spoilage, overproduction, leftovers, etc.)
• Disposal method (trash, compost, donation)

Many restaurants use digital food safety solutions to streamline record-keeping and enhance accuracy in tracking waste.

Step #3 – Collect data

Train kitchen staff to record waste consistently throughout the day. Ensure they:

• Weigh or measure discarded food
• Document waste immediately to avoid missing details
• Note any recurring issues, such as frequent spoilage of certain ingredients

Regular data collection is crucial for analyzing trends and making informed decisions.

Step #4 – Analyse data

After gathering data for a set period (e.g., one week or month), review the log to:

• Identify the most common sources of waste
• Spot trends, such as frequent spoilage of a specific ingredient
• Determine if portion sizes or purchasing habits need adjustment

Step #5 – Implement changes

Based on your findings, adjust your operations to reduce food waste. Potential changes include:

• Optimizing inventory – order only what’s needed based on past waste trends
• Adjusting portion sizes – if customers leave food on their plates, consider smaller portions
• Improving storage – use first-in, first-out (FIFO) methods to reduce spoilage
• Repurposing ingredients – create menu items that utilize excess ingredients

Step #6 – Monitor progress

Continue tracking food waste regularly to measure the impact of your changes. Maintaining a detailed log also supports a strong food defence plan, helping restaurants identify vulnerabilities and prevent unnecessary waste.

How can I ensure my restaurant waste is measured and recorded accurately?

Accurate tracking is essential for understanding your food waste and making informed decisions. Here’s how to make sure your restaurant waste is measured and recorded properly.

Weigh or measure the food waste

Use a kitchen scale or measuring containers to record waste consistently. Measuring by weight or volume provides accurate data that helps in setting realistic waste reduction goals.

Record the type of food waste

Log whether the waste is raw ingredients, prepared food, leftovers, or spoiled items. Tracking different types of waste helps pinpoint issues, such as overproduction or improper storage.

Record the reason for the waste

Understanding why food is wasted is key to reducing it. Common reasons include:

• Overordering or poor inventory management
• Spoilage due to improper storage
• Overproduction in the kitchen
• Incorrect portion sizes leading to plate waste

Identifying patterns helps optimize purchasing and preparation processes.

Record the date and time

Keeping track of when food waste occurs can reveal useful insights. Do certain ingredients expire before use? Is there a trend of overproduction on specific days? This information helps improve ordering and scheduling.

Involve your staff

Your team plays a critical role in tracking food waste. Train staff on how to record waste properly and encourage them to suggest improvements. Engaged employees are more likely to support waste reduction efforts, just as first aid trained staff contribute to a safer workplace by handling emergencies effectively.

How do I analyze the data in my restaurant waste log?

Once you’ve collected waste data, the next step is analyzing it to identify trends and opportunities for improvement.

Categorize the food waste

Divide waste into categories such as:

• Prep waste – trimmings, over-prepped ingredients
• Spoilage – expired or improperly stored food
• Overproduction – food that wasn’t served
• Customer leftovers – uneaten portions

Categorizing waste pinpoints areas for improvement, from better portion control to smarter storage solutions.

Track the volume and frequency of waste

Recording how often and how much waste is generated helps measure the scale of the problem. If a certain ingredient is frequently discarded, it may indicate overordering or inefficient use.

Look for trends

Analyze your log to spot patterns over time. Are certain items wasted more than others? Do specific days see higher waste levels? Recognizing these trends allows for proactive adjustments in inventory, menu planning, and portion sizes.

Identify opportunities for waste reduction

Once you’ve reviewed the data, look for actionable ways to cut waste, such as:

• Adjusting ordering habits to prevent spoilage
• Refining portion sizes to reduce plate waste
• Improving storage methods to extend ingredient freshness
• Repurposing excess food into new menu items

By consistently reviewing your food waste log, you can make informed decisions that save money and improve sustainability.

How can I reduce restaurant waste once I’ve analyzed my log?

After analyzing your food waste log, take actionable steps to minimize waste and improve efficiency:

• Optimize inventory management – Order only what’s needed based on past waste trends. Use first-in, first-out (FIFO) methods to prevent spoilage.
• Adjust portion sizes – Reduce plate waste by offering smaller portions or customizable serving sizes.
• Improve food storage – Label and date ingredients, store perishables correctly, and monitor expiration dates.
• Enhance meal planning – Design menus that repurpose excess ingredients and minimize overproduction.
• Train staff on waste reduction – Educate employees on proper storage, portioning, and cooking techniques to reduce unnecessary waste.
• Implement composting programs – Convert organic waste into compost rather than sending it to landfills.
• Donate surplus food – Partner with local food banks or charities to give away safe, unsold food instead of discarding it.

By consistently applying these strategies, restaurants can cut costs, improve sustainability, and operate more efficiently.
