Australians waste, on average, up to 30% of all food purchased. In NSW, that’s about 315 kg of food per household, and more than $1,000 wasted each year. It’s a terrible shame, isn’t it?

It’s not only money wasted when we throw food in the bin – it’s also the vast amounts of resources, energy, and water it took to produce, process, store, refrigerate, transport, and cook that food.

Food wastage has deeper consequences than its monetary value, being just as much about moral significance and environmental impact as it is about saving a few dollars at the checkout. Australians threw away $8 billion worth of food in 2012 – just imagine the number of hungry mouths that could have fed!

The reality is that today’s world faces some dire scenes of pollution, climate change, water shortage, poverty, and hunger. And – surprise, surprise – food plays a huge roll in all those issues. The more food we waste, the bigger those issues will be.

So how can you reduce your waste?

Well if you cook, chances are you’ll end up with kitchen scraps. And with this in mind, let’s look at ways you can use these scraps instead of throwing them away. For some this could mean composting and worm farms; for others it could mean making a broth.

Here’s how you can reuse food scraps in the kitchen, both to eat and not to eat, with a few recipes to show you just how good it can taste and feel to reduce waste.

5 ways to use food scraps in cooking

Make a broth

Celery tops, onion and garlic skins, carrot peels, leek greens, and other veggie scraps are perfect for creating your own stock or broth. Simply save the scraps in a freezer-safe container until you have enough to cook up a big batch, and once the solids are strained out, toss them on the compost. Brown onion skin actually has tannins in it that when simmered slowly add a gorgeous caramel-coloured hue to your stock – although onion shouldn’t be added to your compost bin. For some flavour, add bay leaves, parsley, and thyme to your scraps and leave it simmering for at least 45 minutes, or in a slow cooker for up to two days. If you eat meat, save up leftover bones and add them to the broth as well. Bone broth has been shown to be beneficial for some people suffering from arthritis – so if you add 2 tablespoons of apple cider vinegar to help extract nutrients from the bones you could be making something tasty that’s good for your health as well.

Make a pesto

The green tops of carrots and radishes are perfectly edible – blend them up with some nuts and a little garlic for a delicious, waste-free pesto that’s a great alternative to the traditional basil and parmesan version. The carrot tops are deliciously sweet and pair quite well with macadamias. Your friends will surely be impressed!

Make a thick soup

Stems, like those from broccoli or kale, are great for making healthy soups that are full of fibre. Simmer them along with some onion, carrots, and celery until soft, blitz a little with a blender, season, and top with a sprinkle of cheese.

Make tea

Tea tastes even more delicious when it’s been lovingly homemade, and scraps like ginger, banana, orange, and apple peels are perfect for a quick infusion/tisane. Just add the peels to some boiling water with a little honey, leave to infuse, and enjoy.

Add flavour to oil

To enhance the full flavour of extra virgin olive oil, why not clean some olive pits to add to the bottle? Olives can be pretty expensive so you may as well get as much from them as you can – adding the cleaned stones really does give the oil a fruitier flavour. You can also try adding leftover bits of garlic, chilli, and the stalk of herbs like rosemary or thyme for different types of tasty infusions. Just remember to use a smaller bottle for this and keep it in the fridge, as adding ingredients can reduce the shelf-life of your oils.

5 ways to reuse food scraps, without eating them

Stop brown sugar from hardening

Place a small amount of citrus peel in your brown sugar to stop it from hardening. Just ensure you keep the sugar in the fridge to stop the peels from rotting!

Clean cookware with apple peel

Apple peel is a natural cleanser that’s cheaper, safer, and much kinder on the environment. Simply place the peels with some water in your dirty aluminium cookware, bring to a boil, and let simmer for around 30 minutes. The acid in the apple peels will remove stains and discolouration.

Make carrot oil

Carrot oil is wonderful for the hair and skin, and can easily be made using scrap carrot peel. Start by saving your carrot peel in the freezer until you have the peels from around 12-15 carrots. Place them in a saucepan or slow cooker and add coconut oil – or any oil of your choice – to cover. Using the lowest temperature setting, infuse the oil for at least 24 hours before straining with a cheesecloth or fine mesh strainer. Pour in a jar and store for 6-8 months.

Keep pests away

Prepare yourselves for a life-changing tip… Cucumber peels are one of the most natural and cost effective pest control solutions out there! Use the peel to reduce minor pest problems, such as ants, moths, mites, wasps, and silverfish. The more bitter the peel, the more effective it is at keeping bugs at bay. Just add the stips to a spray bottle with some water and apply around window frames, doorways, cupboards and the pantry.

Refresh your garbage disposal

If you have a sink-composter, you should occasionally throw citrus peels in this garbage disposal unit to remove unwanted smells. You can also freeze some peel in an ice tray and throw in a citrus ice cube every now and then to freshen the system and help knock off any debris caught on the shredders.

Put it into practice

You see, there really is no end to how you use your food scraps! They can be pickled and stored in the fridge, boiled and transferred into broth, infused into oil to make skin and hair feel soft, and used for all-natural cleaning. You can compost them, regrow them, crisp them up in a microwave, make delicious drinks with them, make sauces and soups with them, create coulis, pie filling and jam with them, and infuse them to make tea. And this is just the beginning!

There’s no excuse for not prolonging the life of your food scraps and making the most out of every part be it fruit, vegetable or protein. So put your thinking cap on and get creative in the kitchen and you could save well over $1,000 per year on your grocery bills. We hope you’ll be pleasantly surprised at just how great food scraps can be.
