How to reduce food waste: a guide for work and home

Australians throw out between $8-10 billion of food every year. That’s a whopping 4 tonnes of food and means 20% of the food we purchase ends up in the bin. This is equivalent to 1 out of every 5 grocery bags. Furthermore, the average Australian household throws approximately $1,036 worth of food away every year. Crazy right?

Out of the $8 billion, what do we waste every year?

It’s time we do something about this.

We hate food waste here at Order-In and we want to give you some tools and practical tips to reduce your food waste, both at home and at work. 


How to reduce food waste at work

Order corporate catering wisely

Use our handy quantity guidelines to ensure you order just the right amount of catering for your next working lunch or corporate event. Although it can be stored in the office fridge, most of our leftovers inevitably end up in the bin. It’s important to find the balance between too little or too much food. Have a chat to our friendly corporate catering experts if you need some advice. We'll will be happy to assist and ensure no one goes hungry, while at the same time, no food goes to waste.

Support sustainable caterers

If you’re after some catering that cares about the environment, check out our sustainability rating. At Order-In, we ask all of our suppliers a few questions regarding sustainability practices and give them a rating out of 5 depending on their answers. This means you can still enjoy delicious catering without having a guilty conscious.

Doggy bag it

Doggy bags are a great way to reduce food waste! Extra food can be placed in the office kitchen for other staff to enjoy, or allow staff to take doggy bags home.

Bring lunch from home

Packing a lunch from home can reduce food waste majorly. Whether it’s last night’s leftovers, a fresh sandwich, or even some fruit, packing food for the day means you don’t need to buy any unnecessary, single-use plastic and you have a set portion size. Plus, it decreases home leftovers and waste!

Aim for in-season food

Seasonal food is likely to be locally produced and be better for the environment. Food that needs to travel half-way around the world just to end up on your plate uses excess energy which means lots of greenhouse gas emissions. Local food not only reduces this impact, it’s also tastier and better for you! Plus, seasonal food is likely to be locally produced, which means you’re also supporting our farmers and growers. Win-win!

Reuse what you can, wherever you can

Use reusable plates, cups, cutlery, glasses and containers when you’re eating at work. Whether that means bringing things from home, or stocking the office kitchen with crockery and cutlery supplies, these little steps make a big impact in the long run.

At your next working lunch, conference or corporate event, use glasses and pitchers of water instead of bottled water.

When choosing disposal items, choose utensils and serve ware that can be recycled or composted.

At Order-In, we make sustainable packaging a priority. We recommend and provide bio-degradable corporate catering boxes and utensils to our corporate caterers.

Temperature control

Storing food correctly to optimise its lifespan not only avoids food poisoning, but gives people a change to polish off those leftovers before they head to the bin. Make sure your fridge and freezer are set to the correct temperature. Cold food should be stored in the fridge at 5 degrees or colder to reduce the spread of bacteria. The freezer should be less than -18 degrees. Store any leftover food in airtight containers or wraps.

Here are some additional tips for organising your fridge.

Donate, don’t discard

An estimated 1.9 million Australians go without food because they can’t afford it. We’re passionate about food and giving back to the community and support organisations like OzHarvest. If you’ve ordered too much food, or if a meeting has been cancelled at the last minute, don’t just chuck it. Donate your still-consumable food to OzHarvest and they’ll redistribute it to the people who need it most.

How to reduce food waste at home

Plan before you shop

Before you go grocery shopping, ensure you have an idea of what meals you want to cook throughout the week, what ingredients you already have in the fridge or pantry and make a shopping list!
This pre-grocery store checklist will make sure you don’t buy more than you need, or are unlikely to use. Who knew saving the environment could save you money?

Buy what you need

Buy only what’s on your list and avoid impulse buys! If you only need 1 capsicum for a recipe, don’t buy a bag because it’s on special. A lot of food waste comes down to simply buying too much at the supermarket to begin with.

Funny-looking produce is OK to eat

Food is awesome in whatever shape and size it comes in. Just because it looks funny or isn’t perfect doesn’t mean it’s not good to eat.

Tip: Instead of grabbing the last bunch of bananas, gather up a few of the singles that have been broken off. People usually avoid these perfectly delicious bananas and they end up being thrown away.

Fee fi fo fum

When unpacking your groceries, use FIFO (First In, First Out). This means moving older products to the front of the fridge, freezer or pantry and putting the newer products in the back. You’re more likely to use the older stuff first before it expires, thus reducing food waste.

Use your leftovers

Designate one day a week to using your leftovers or food items that are about to expire. Leftovers can be frozen and saved for later or packed for tomorrow’s lunch. Check out some easy lunch ideas for work here.

Make the most of what you've got

Vegetables, bones and meat scraps could be used to make stocks. Use rinds and citrus fruit zest to add extra flavour to meals. Don’t throw away overripe fruit – use it in smoothies, muffins or cakes. Wilted vegetables can be used in soups or combined with other ingredients to make a delicious and healthy juice.

If you’ve got a surplus of fruit, why not freeze it (mmm mango smoothies), make jam or chutney or pickle it.

Store it better

If you’re regularly dealing with pest problems, or throwing away stale chips, cereal and biscuits, it’s time to invest in quality, airtight containers. Reusing glass jars is also an inexpensive way to store food items and it’s environmentally friendly. Next time you run out of instant coffee, or use up a pasta sauce, simply soak and wash the glass jars for easy reuse! Proper storage solutions not only helps with food safety, but you will also have to buy less, more often.

It’s important to make sure your fridge is running at maximum efficiency so food stays as fresh as possible.

  • Check the seals and the doors close tightly
  • Keep your fridge at between 3 to 5 degrees and the freezer at between -15 to -18 degrees

More fruit and veggie storing tips

Here are some extra fruit and veggie storing tips to help keep them fresher longer

  • See ya later floppy celery sticks! Wrap celery stems in aluminium foil to keep them fresh and crunchy
  • Store onions and potatoes separately - keeping them together actually sends them off faster
  • Place potatoes in a paper bag and store in a cool, dark place. Don’t store them in the fridge as the cool temperatures will convert the potato’s starches into sugars more quickly
  • To keep carrots fresher longer, cut off the tops and wrap them in a damp cloth before placing in the fridge
  • Store apples in the fridge to keep them fresh and crisp

Keep up to date with use-by dates

Expiration dates don’t always mean the food is off. They’re just a suggestion for peak quality, however, if stored properly, most foods will stay fresh several days past the “use-by” date.

If it looks, smells and tastes ok, it should be fine to eat, otherwise, it’s time to toss it.
