Where Does Food Waste Come From?
Food waste can happen at almost every stage of a hospitality operation.
Over-ordering is one common cause. Customer numbers can change from day to day, making it difficult to predict exactly how much food will be needed.
Waste can also happen during preparation. Ingredients may be discarded during cooking and preparation, while food that has already been prepared may not be used during service.
Then there is food left by customers. Looking at what regularly comes back on plates can help businesses understand whether portion sizes or certain menu choices need to be reviewed.
These are some of the key areas businesses need to consider when tackling food waste in the hospitality industry.
Why Is Measuring Food Waste Important?
Before a business can reduce food waste, it needs to understand what it is throwing away.
WRAP recommends that hospitality and food service businesses measure their food waste to understand how much is being wasted, where it happens and why. This helps businesses prioritise the areas that need the most attention. (Source: WRAP's Hospitality and Food Service Guidance)
For example, a kitchen may find that a large amount of waste comes from overproduction, while another may discover that ingredients are regularly going out of date.
Without measuring waste, these patterns are much harder to identify.
How Can Hospitality Businesses Reduce Food Waste
Plan Purchasing Around Demand
Using previous sales, bookings, seasonal trends and expected customer numbers can help kitchens make better purchasing decisions.
The goal is not simply to buy less. It is to buy closer to what is actually needed.
Improve Stock Management
Regular stock checks and clear storage systems can help teams keep track of ingredients and use them before they become unusable.
Rotating stock and making sure older ingredients are used first can also reduce unnecessary waste.
Review Preparation Waste
Measuring what gets thrown away during preparation can highlight recurring problems.
Small changes to preparation methods, ingredient use or kitchen processes can help reduce the amount of food discarded before it reaches the customer.
Look at Portion Sizes
Food left on customers' plates can provide useful information.
If particular dishes regularly come back with large amounts of food remaining, businesses can review portion sizes or consider whether those dishes are meeting customer expectations.
This does not necessarily mean making every portion smaller. The aim is to understand what customers are actually eating and identify patterns of avoidable waste.
Make Better Use of Ingredients
Menu planning can also help reduce waste.
Using ingredients across several dishes gives kitchens more opportunities to use food before it reaches the end of its shelf life. Seasonal menus can provide another way to plan around readily available ingredients.
Thoughtful menu planning can therefore help kitchens make better use of what they buy rather than treating unused ingredients as inevitable waste.
Food Waste Is a Business Issue Too
The cost of food waste goes beyond the price of the ingredients themselves.
Figures from WRAP suggest that food waste costs the UK hospitality and food service industry around £3.2 billion each year, averaging approximately £10,000 per outlet. (Source: WRAP's Hospitality and Food Service Figures)
Businesses also invest labour, energy, storage and preparation time into food that is ultimately not eaten.
This makes food waste in the hospitality industry both a sustainability issue and a business efficiency issue. Reducing waste can therefore support environmental goals while helping businesses make better use of their resources.
How Pow Food Is Tackling Food Waste
For workplace catering, reducing food waste needs to be considered as part of the whole food operation rather than as an afterthought.
At Pow Food, zero-waste thinking is built into menu development and kitchen operations. The company has developed Zero Waste Kitchens and Zero Waste Menus, while also working with carefully selected suppliers and looking at waste from sourcing through to serving. (Source: POW FOOD Sustainability)
Pow Food also works with City Harvest to donate surplus meals, helping edible food reach people who need it rather than becoming waste. Its workplace catering service combines this approach with nutrition-led menus designed for London teams. (Source: POW FOOD Workplace Catering)
For workplace caterers, reducing food waste in the hospitality industry is not just about what happens at the end of a service. It starts with better planning, thoughtful menus and responsible sourcing, and continues through preparation, serving and surplus management.
By looking at the whole operation, hospitality and catering businesses can identify where food is being wasted and make practical changes that benefit both the environment and the business.
