If you've ever worked in a restaurant, you know the drill. At the end of the night, trays of perfectly good food go straight into the bin. Prepared salads, baked goods, prepped ingredients that didn't get used. It happens every single day, across every type of food business in Australia.

The hospitality industry is one of the largest contributors to commercial food waste in the country. And the cost isn't just environmental. It hits the bottom line hard.

The Numbers

Australia's commercial food sector (restaurants, cafes, takeaways, catering, and hotels) generates an estimated 1 million tonnes of food waste per year. That's roughly 40% of all commercial and industrial food waste in the country.

For an average restaurant, food waste can account for 5% to 15% of total food purchases. On tight margins, that's the difference between a profitable month and a loss.

Where Does Restaurant Food Waste Come From?

Overproduction

Most kitchens prepare more than they sell. It's built into the model. You can't predict exactly how many customers will walk through the door, so you prepare extra. Whatever doesn't sell gets tossed.

Spoilage

Fresh produce, dairy, and meat have short shelf lives. If stock isn't rotated properly or deliveries are too large, ingredients go off before they're used.

Plate Waste

Customers leave food on their plates. Oversized portions are a major contributor. Studies show that up to 30% of plate waste in Australian restaurants could be avoided with better portion sizing.

Prep Waste

Peeling, trimming, and portioning generates waste. While some of this is unavoidable, a lot of it could be reduced with better techniques or by finding uses for offcuts (stocks, staff meals, specials).

The Real Cost

Food waste costs Australian hospitality businesses an estimated $8 billion per year when you factor in:

Purchase cost of ingredients that never get sold
Labour cost of preparing food that gets thrown away
Disposal cost of commercial waste collection
Energy cost of storing and refrigerating food that's never used

For a single restaurant, that can easily add up to $20,000 to $40,000 per year in preventable waste.

What Can Restaurants Do?

Track Your Waste

You can't fix what you don't measure. Spend a week tracking what goes in the bin. Log the item, the quantity, and the reason (overproduction, spoilage, plate waste, prep waste). Patterns will emerge quickly.

Right-Size Your Orders

Use your waste data to adjust ordering. If you're consistently throwing away the same items, you're ordering too much of them. Work with your suppliers on smaller, more frequent deliveries.

Sell Surplus Through LastBite

Instead of throwing away end-of-day surplus, list it as a surprise bag on LastBite. Customers pay through the app and pick it up before you close. You recover revenue from food you'd otherwise bin, and you reach new customers who discover your business through the platform.

It's free to join. No sign-up fees, no commission, no listing fees. You set the price and the pickup window.

Donate What You Can

For larger volumes of surplus, organisations like OzHarvest and Foodbank accept donations from restaurants. You may also be eligible for tax deductions under the Sharing is Caring provisions.

Train Your Team

Kitchen staff are your first line of defence against waste. Train them on proper stock rotation (first in, first out), portion control, and creative use of offcuts. Many chefs welcome the challenge.

The Opportunity

Reducing food waste isn't just about saving money (though the savings are real). Customers increasingly choose businesses that take sustainability seriously. Listing on food rescue platforms, reducing portions, and talking about your waste reduction efforts can become a genuine competitive advantage.
