Food Waste That You Can “Re-Use”

It’s Zero Waste Week this week, and the theme is “re-use”. I talked last week about household items I use to generate less waste, particularly packaging waste. That got me thinking about food, or more specifically food waste. There are so many food “waste” items that can actually be re-used that I thought I’d write a list, to encourage you to think twice before committing something straight to the bin (even if it is the compost bin).

10 Food Waste Items that you can Actually “Re-use”

1. Spring onion roots

Those end bits you chop off of a spring onion with the roots still attached don’t need to go in the bin – they can be replanted and will re-sprout! Celery will do the same thing. If you grow your own you could cut them at soil level rather than pulling up, and leave the roots in the ground to re-sprout!

2. Vegetable peels

If I can avoid peeling my vegetables then I don’t do it, but occasionally peeling them is required for a particular recipe. Make sure the skins are scrubbed first, then save the peels, toss in a small amount of oil, sprinkle lightly with salt and spread out over a baking tray. Bake for around 10 minutes on one side, turn over and bake for another 5 – 10mins at a medium heat. Voila! Your very own zero waste vegetable crisps! I’ve made these using potato peels, as well as parsnip, carrot and beetroot peels – and they are all delicious : )

Potato and beetroot peels make great vegetable chips – just brush with oil and pop in the oven.

3. Veggie scraps

Rather than making vegetable stock with new vegetables, I save up scraps in my freezer in a big glass jar, and once the jar is full I use these. I use the tops and tails, stems and stalks, and the outer white layers of onion that aren’t suitable for cooking with. I tend to avoid using cabbage as it can be overpowering. Recently I’ve started separating in the freezer, so I have a big jar of onion tops, tails and skins, and a smaller jar of other bits and pieces, so I can make the stock into the flavour I want more easily.

4. Lemons (and other citrus)

Lemons are made of so many good parts, it just doesn’t make any sense to use one of them and throw the rest away! Before juicing a lemon you can zest it (remove the yellow skin) with a grater or zester, or even a potato peelers – just chop afterwards. The zest can then be frozen, or dried in the oven at a low temperature and stored in the pantry. The juice can also be frozen too (I use an ice cube tray, then transfer the frozen cubes to a glass container).

If you don’t want to zest them, the peels can be made into candied citrus peel. A final resort is to add the peels to homemade household cleaners (like vinegar) to give a citrus fragrance.

This isn’t just true for lemons – it’s perfect for all citrus fruit.

Zero Waste Week Re-Use Lemons Citrus

There’s no need to use just one part of the citrus fruit – use all the bits!

5. Egg Shells

This isn’t one you can eat – well, not one that I eat – but I think it’s worth mentioning as egg shells are one of those things that don’t break down well in compost or in worm farms. Not whole, anyways. When I’ve used eggs, I rinse the shells and leave to dry, and then pop into a jar. Once the jar is reasonably full (you can squish them to fit more in) I add them to my food processor and grind to a powder. If you don’t have a good food processor you can use a spice / coffee grinder, mortar and pestle, or even a bag (reusable of course!) and a rolling pin. The powder can then be added to compost, a worm farm or even directly on the soil.

Egg shells can be ground up to make a great soil additive.

6. Coffee Grounds

This is another food waste item that doesn’t need to go in the bin. Coffee grounds are great for the soil so even if you don’t have a compost bin or worm farm, emptying your coffee pot directly under a tree or shrub adds nutrients to the soil and saves waste. The caffeine in the coffee is also thought to act as a slug deterrent – hurrah!

Another use for coffee grounds is to make your own DIY body scrub. It’s a natural alternative to those plastic microbeads that are so damaging to the environment, and one that uses a waste product! Whether you just use the grounds on their own or mix with oils or other ingredients depends on your level of patience (I am all for the simplest option) but one thing is required – get a filter for your plughole or you’ll end up blocking your drain!

7. Carrot Tops

It just doesn’t make any sense to chuck the lush green tops that come with real carrots. I find that they make a great alternative to basil in pesto. You can use any pesto recipe and sub some of the basil (from half up to tho-thirds) with carrot tops. I still use basil to keep that distinctive flavour, but you can make it using carrot tops alone if you prefer. You can also use the leaves in salad.

It doesn’t have to stop at carrot tops either – beetroot leaves, celery tops, in fact, most other leaves can be eaten raw or cooked with. You just need to get creative!

8. Juice Pulp

Juicing vegetables and fruit can be delicious, but so much waste is generated. The great news is, it can be made into food of its own! I make flatbreads using the pulp from juicing carrots and the same recipe should work with beetroot. You can also incorporate pulp into baking, or search for other recipes on the internet. It takes a small amount of preparation beforehand such as ensuring cleanliness, removing pips or seeds, and peeling if necessary (eg fruit such as apples). If you’re not sure what to do with it, you can always freeze until you have enough or you’ve found a recipe to try.

8. Nut Pulp

If you make nut milk, particularly almond milk, then straining will leave you with a large amount of almond pulp. I can’t believe anyone would throw this in the bin! Nuts are expensive, but also full of goodness. What a waste! Again, there are hundreds of recipes out there for using nut milk pulp. The simplest is to mix with s0me olive oil and a little salt, roll out, score into squares and bake – and you have crackers! There are plenty of both savoury and sweet recipes to try.

Whilst the pulp is freezable, another option is to dry out and store in a jar in the pantry. Spread on a baking tin and put into the oven on a low  heat, checking often. Once it dries, pop into the food processor to whizz into a powder, and finish in the oven to ensure no damp bits remain. The resulting powder is more of a flour as the fat has been squeezed out to make milk, leaving the fibrous part, and is great to use in baking.

9. Bread Crusts

Those dry scrappy bits of bread that have slowly turned into rocks don’t need to go in the bin. Ditto old bread rolls. Chuck them in the food processor, grind into breadcrumbs and freeze. Actually, they will keep in a jar in the pantry for a few weeks if completely dry (you can dry out in the oven first to be sure).

Zero Waste Week Breadcrumbs

Use stale bread and old crusts to make breadcrumbs.

10. The Liquid from Cooked Beans / Pulses

This can be the liquid from tins of beans, if you buy those, or the liquid from cooking your own. It has its own name – aquafaba – and it can be used as an egg replacement in baking as well as an egg alternative to make meringues and macaroons. Don’t just take my word for it though – check out the Vegan Society’s Aquafaba article to see what I’m talking about. I am completely fascinated by this – the idea of using something that you’d pour down the drain to make actual delicious food! You don’t need to be a vegan to think this is a great idea! So far I’ve eaten meringues made this way (not by me, by the accountant at work – she was as mystified and intrigued as I was!) and I was very impressed. Stay tuned for some experiments later in the year!

There you have it – 10 food items that you can re-use. Even if you’re a committed composter, it’s always better to find a way to re-use something than to rot it!

Now I want to hear from you! Things always seem obvious after the fact, but several of these were real “a-ha!” moments for me when I first came across them. I’m sure there are plenty more that I haven’t come across yet, and I need your help! I want to know what food waste items you re-use, and how. Have you had any great successes? Any fails? Any recipes you’d like to share? Please share your thoughts, experiences and tips in the comments below!

Zero Waste Living: 15 Things I Reuse (And One I Don’t)

It’s Zero Waste Week on 7th – 13th September this year, and once again I’ve signed up to be an ambassador of this awesome initiative. Of course I’ll still be talking about waste on the other 51 weeks of the year (you know me!), but I do love it when a community really gets together to draw attention to the subject, the issues and the solutions, and it’s such a great opportunity to spread the zero waste message just that little bit further ; )

This year the topic is “Reuse”. As someone who strives to be zero waste, I love to reuse things! It eliminates a lot of waste, but also a lot of spending on unnecessary things, and a fair amount of clutter too. Who wouldn’t want to get the most use out of the things they own?!

15 things that I swear by to live my Zero Waste lifestyle…

1. A reusable coffee cup.

Even if you don’t drink takeaway coffee, I think owning one of these is invaluable. I carry mine with me always. It’s useful for getting water from public water fountains or if you go into a cafe and find they only serve takeaway cups. If you fly, it’s great for drinking any kind of drink in a plane. I’ve also used mine at parties where wine was served in disposable wine glasses. If I’m buying ice cream I’ll use the cup rather than one of their disposable ones. Plus, because it was a lid, it’s great as an impromptu container.

Reusable Coffee Cups aren't just for coffee!

Reusable coffee cups aren’t just for coffee! They make great reusable containers for all kinds of treats!

2. Reusable bags.

I was on the “bring my own bag to the supermarket” train back in the early 2000s, and would pack all my plastic-packaged goods into my own reusable tote – “oh no, I don’t need a bag!” Little did it occur to me that I could use reusable cloth / mesh bags for the produce I was putting inside the tote! Even if bulk stores aren’t local to you, reusable bags are great for buying loose fresh produce.

Reusable bags aren’t just for food shopping either! You can use that same reusable tote for other shops too. These days I always take my own bag to clothes shops, hardware shops, kitchenware shops…anywhere where I need to pick something up.

Reusable Bags for Zero Waste Week 2015

Reusable bags come in all shapes and sizes…there’s no need to limit yourself to one big tote!

3. A water bottle.

This is a total no-brainer for me. Aside from the fact that bottled water is predominantly unregulated and plastic leaches chemicals into the water (not to mention the ethics of bottling water in drought-stricken regions like California or countries where most of the population don’t have access to safe drinking water like Fiji), sucking water out of the ground trucking water across states and even across countries is a huge and unnecessary waste of resources. Most of us have access to municipal water at a fraction of the cost (as much as 300x cheaper). If you really don’t like chlorine or fluoride, it’s possible to get a water filter fitted.

If you’re in any doubt about bottled water, watch the documentary Tapped.

4. Reusable Cutlery.

I have a nifty little bamboo set that was a gift, but you can also find metal camping sets, and charity shops always have plenty of cutlery too if you want to avoid buying new. Alternatively, use what you already have in the kitchen! My set contains a knife, a fork, a spoon and a set of chopsticks. Plastic cutlery often isn’t fit for the purpose – have you ever tried to cut anything with a disposable plastic knife?! I’ve successfully peeled and de-stoned a mango with my wooden knife!

Reusable Bamboo Cutlery Zero Waste Week 2015

Reusable Bamboo Cutlery (it would be just as easy to make a set with op-shop finds) and I’ve added a stainless steel straw to complete the set!

5. A Reusable Straw.

Whilst I don’t use straws often, I think that single use straws are up there as the most wasteful plastic items out there. They are also one of the top 10 items found in beach clean ups. I have a stainless steel one which I keep in my cutlery pouch, and a glass one which I prefer, and came with its own cleaning brush.  Carrying a straw means I’m never caught out, but also it’s handy to lend to friends! I know from experience that there are a few drinks that need straws – icy drinks like dacquiris and fresh coconuts, for example.

6. Reusable Containers.

Just as it never occurred to me for years to bring my own reusable produce bags to the shops, it never occurred to me to bring my own containers, either. Now I take reusable containers (pyrex, stainless steel, glass jars and occasionally plastic) to the deli, bulk stores, Farmers Market and bakery to avoid any unnecessary packaging. It certainly makes unpacking much easier – everything goes straight in the fridge / on the shelf!

I also find them great for storing leftovers, keeping perishables fresher, and freezing food, as well as great containers for non-food items.

7. Cloth Wraps.

Containers are great, but bulky and not always practical – and if you stick to glass and stainless steel, they are fairly costly too! I have some reusable wraps (another gift) that I use carry lunch or snacks when space (or weight) it at a premium. They are also great for purchasing food to-go from cafes and avoid paper bags. If you don’t want to buy new ones you can make your own using old material (reuse…yay!) and beeswax (soy wax should work if you’re vegan). Find a tutorial for making your own beeswax wraps here. They are also great for keeping fresh herbs and salad leaves fresher in the fridge, and can be shaped and molded to cover bowls for leftovers.

8. Old Clothes.

Whilst I’d love to learn, I’m no sewer, and cannot whip an old worn shirt into a snazzy waistcoat or other wondrous design as seen on Pinterest. I can darn holes, and that’s it. Once my clothes are truly worn and past repair, they can still be reused. If you’re feeling creative, make into reusable food wraps (see above). I cut them into rags, where they begin life as dishcloths. As they wear further they are downgraded to kitchen surface cleaning cloths, bathroom cleaning cloths, floor cleaning cloths and finally toilet or bike cleaning cloths.

In the past I’ve been sucked in and purchased those “eco friendly” cleaning cloths. This makes no sense when I have suitable fabric at home that costs me nothing and wastes no new resources!

9. Old Towels.

You can cut up old towels as mentioned above, but another great use for worn towels and bed sheets is to donate them to animal shelters. They are always in need of them, and it might be a better use than cutting that bath sheet up into 62,000 dish cloths that you’ll be using for the next 15 years!

10. Reusable Cotton Rounds.

When I was a kid, I used a flannel to wash my face. As I grew into a teenager I began using disposable cotton rounds (or cotton wool) to clean my face (which chemical-laden cleansers) and to remove make-up. That clever marketing got to me! These days I use good quality soap, I have reverted back to a flannel and I have reusable fabric rounds for removing make-up, which I throw in the washing machine and re-use. You can buy these or Etsy, or if you’re crafty make your own from old clothes (see # 8).

11. A Body Brush.

Body brushing is great for increasing circulation and removing dead skin cells, and saves buying another product for the bathroom – particularly as these exfoliating products often come in non- or only partically-recyclable containers… and commonly contain plastic microbeads to act as the exfoliant!

12. Toothbrushes.

Once my toothbrush is no longer fit for using to clean my teeth, it gets relegated to the cleaning basket. Toothbrushes are great for cleaning grouting, tiles, awkward corners, taps and other fiddly places, and also for cleaning bikes.

13. Baking Paper.

I’ve had this debate a few times in Instagram and Facebook – if I’m zero waste should I be using baking paper at all? Which led me to write about The Rules, and conclude that whilst it might not be the most zero waste thing to do, it does mean my homemade chocolate brownies are infinitely more delicious. Maybe in the future I’ll change, but for now it stays. That said, I use it very sparingly, and yes, I reuse it. I find a quick wipe when it’s just come out the oven is enough to clean it, and there’s always the other side. I bake often, so it doesn’t end up hanging around for too long. When it’s finished, I use it to make worm farm bedding so it doesn’t go in the bin.

As long as the quality of my chocolate brownies is at stake, the baking paper stays.

As long as the quality of my chocolate brownies is at stake, the baking paper stays. But it always gets reused.

14. A Hankerchief.

We don’t buy tissues for our home. Instead, I use a handkerchief. My dad has always used a hankerchief, and as a kid I used to think it was completely gross. Isn’t it funny how you grow up and realise that a lot of what your parents did (and said, and told you to do) was actually not as daft as you thought?! (Note – don’t ever tell them I said that!) I started using one when I realised that you couldn’t buy boxes of tissues without the plastic around the dispensing hole. Then I realised that hankies make so much more sense, and they are far softer on the nose than any of those cleverly marketed and relatively expensive fancypants tissues ; )

15. Old Envelopes.

You can have a “No Junk Mail” sticker on your mailbox, and switch to paperless billing, and still people keep sending you stuff in the post. Grr! I use the envelopes as notebooks, to write shopping lists (pinned onto the fridge door) and I cut out squares of blank paper which I use to stick over the address to reuse other envelopes and mailing bags that I’ve received. Reuse is better than recycling, and I never need to buy these things!

…and One I Don’t.

  1. There’s one reusable item that some zero-wasters have adopted which I haven’t, and that is…reusable toilet paper (cloth wipes). It’s just not gonna happen in our house. I’m not opposed to the principle (although my husband draws the line here), but I think the constant need to keep up with the laundry (and bear in mind we live in a city with 40°C summers and no air con in our home) means the hygiene factor wins. I’m sure it works for some people, but it won’t be working for us!
toiletpaper

Recycled, ethical, plastic-free…but not zero waste : /

The thing about “reusing”; it doesn’t have to be about getting creative with empty bottles of dishwashing liquid and old toilet rolls. It’s as much about the everyday stuff that we use every day. Plus, because it’s stuff we use every day, being able to reuse (rather than buying new and then discarding to landfill)  has a far bigger impact – on our wallets, on the way we use our time, and on the environment. Why would you want to live any other way?!

Now I want to hear from you! What are your favourite things to reuse? What would you add to the list…or is there anything you’d add to the “No Go” list?! What have you found the most helpful in your zero waste journey? What has been the biggest struggle? Are you tempted to take part in Zero Waste Week this year, or have you already signed up and if so, what’s your personal challenge?! I love hearing your thoughts so please tell me in the comments below!
