One billion tonnes of shame : the global crisis of food waste & where the issue truly begins

Every year, over a billion tonnes of food go to waste, harming our wallets, our planet, and our conscience. Discover why it happens, what it costs us, and how to waste less with practical, everyday tips.

Food produced
globally wasted
1 /5

Every year, one-fifth of all food produced globally is wasted.

Let that sink in for a second. One out of every five bites, gone. Tossed. Forgotten in the back of the fridge, left to fuzz over with guilt and mold, scraped off plates into trash cans like it never mattered. And it does matter. Not just because we’re throwing money away (which we are), or because someone, somewhere, would’ve been thrilled to have that bruised apple we just couldn’t be bothered with (which they would), but because this level of waste is simply insane.

It’s like we’ve collectively decided the planet is a buffet with no closing time.

Of course, most of us aren’t villains twirling our forks like, “Mwahaha, I shall waste this perfectly good pasta bake!” The truth is, there’s a whole mental load behind every meal. We’re juggling work, family, and a thousand little decisions before dinner even hits the plate. We forget what’s in the crisper drawer, misjudge portions, or stare at leftovers with zero brainpower left to get creative. It’s not evil, it’s habit, it’s culture, and it’s the exhaustion that comes from constantly thinking about food. And maybe, just maybe, it’s time to change that. We don’t need shame, just a spark of curiosity and creativity to turn what’s left into something delicious.

So, this isn’t a lecture. It’s an invitation, to think, to cook, to waste less, and maybe even feel good about it along the way.

Why we need to talk about the food we throw away

Because what’s rotting in the bin says more about us than we’d like to admit.

The Waste
is Real

Staggering stats that prove food waste isn’t just a side dish — it’s the main course.
Tonnes of food wasted
1.05 t
Quantity wasted per person
132 kg

Let’s start with the numbers, not because they’re the most exciting thing you’ll read today (they’re probably not), but because they hit hard. In 2022, the world wasted 1.05 billion tonnes of food. That’s 132 kilograms per person. Basically, imagine each of us lugging around a small refrigerator filled with rotting leftovers, forgotten takeout, and mystery items from the back of the pantry.

Even more maddening? Most of that waste (60% of it, to be exact) happens at home. Yep, not in the fancy restaurants or the big supermarkets (though they’re not off the hook either), but right in our own kitchens. That’s over 600 million tonnes of food chucked by regular people like you and me. People who probably meant well when they bought that bunch of kale and then watched it wilt into oblivion.

Wasted at home
60 %
Food wasted when reaching
the consumers
19 %

Food services (restaurants, hotels, catering) come next, wasting another 290 million tonnes, and retail (think grocery stores, markets, etc.) tosses out 131 million. Add it all up, and nearly one-fifth (19%) of all food that reaches consumers is binned. Not eaten. Not donated. Just gone.

And here’s the kicker: that doesn’t even include the food that disappears before it even gets to the store shelves, lost somewhere between the farm, the truck, the warehouse, and the display. That’s food we never even had a chance to forget in the fridge.

It’s overwhelming, right ? Even so, we have the ability to alter that.
After all, if the biggest chunk of the problem occurs in our own homes, then maybe that’s exactly where the solution starts.

From Fridge to Fallout

How wasted food drives emissions, deepens inequality, and takes a bite out of the planet

Here’s where it gets even more absurd, and honestly, kind of infuriating. Wasting food isn’t just about tossing out a bruised tomato or letting your leftovers grow fuzz in peace. It’s about throwing away all the energy, water, land, and labor that went into making that food in the first place. And spoiler alert : the planet notices.

Food waste is responsible for 8 to 10% of global greenhouse gas emissions. That’s nearly five times more than what the entire aviation industry emits. Yes, you read that right. We talk a lot about cutting back on flights, but barely whisper about the half-eaten salad we tossed last night that quietly added to the planet’s carbon bill.

And it doesn’t stop there. All that wasted food means wasted water , pressure on soil, deforestation to grow things no one ends up eating, and a big fat blow to biodiversity. It’s like taking a sledgehammer to the environment just to not finish your dinner.

Meanwhile, while we’re busy tossing perfectly good food, million of people go hungry, and over a third of the global population deals with food insecurity. That’s not just tragic, it’s obscene. It’s a broken system where abundance and lack coexist, not because we don’t have enough, but because we don’t manage what we have.

Leftovers and Letdowns

When waste hits your wallet and your conscience

If we imagine what it’s like to waste food at home, it’s like pulling money out of your wallet, crushing it into a ball, and tossing it in the bin. On average, households lose €100 to €160 a year this way. That’s a week of groceries, a dinner out, maybe even one of your bills. All gone because we forgot that half-head of lettuce existed.

But it’s not just about money. There’s a deeper discomfort, one that kicks in when you scrape untouched food into the trash while knowing that million of people go hungry every day. It’s hard to ignore the irony of overstocked fridges in some homes and empty plates in others.

And let’s shatter a myth while we’re at it : food waste isn’t a “rich country problem”. Globally, the difference in household food waste between high- and low-income countries is only about 7 kg per person per year. That’s barely a shopping bag’s worth. In other words, no one gets a pass.

Yes, it’s easy to feel overwhelmed. But the good news is that the power to make a difference starts right where you are : in your kitchen, at your table, and with the choices you make every day. Waste isn’t inevitable. It’s just been normalized. And it’s time to unlearn that.

What’s really going to waste in our kitchens

Because food waste starts long before it hits the trash, and the reasons are closer to home than we think.

Let’s face it, storing food properly sounds boring. It’s not glamorous. It doesn’t involve spice blends or new cookware. But it might just be one of the most powerful ways to stop wasting perfectly good food.

And yet, we’re messing it up, globally. Rising temperatures and extreme heat waves are already shortening the shelf life of fresh produce. Add inadequate cold chains, the systems that keep food chilled from farm to fork, and you’ve got a recipe for spoilage before the food even gets to your plate. This hits hardest in regions where reliable refrigeration is a luxury or where power outages are as common as mealtime.

But let’s not pretend home kitchens are off the hook. Most of us have, at some point, shoved spinach in the wrong fridge drawer, forgotten to close a cereal box properly, or left leftovers to morph into unrecognizable science experiments. Bad storage habits, like overcrowding your fridge or ignoring that “first in, first out” rule  slowly chip away at your grocery budget, one moldy item at a time.

It’s time to know what goes where, when to use it, and how to prevent your fridge from turning into a graveyard of good intentions.

Misjudged portion sizes

Your eyes are not your stomach, and neither is your trash can

We’ve all done it. Scooped an extra handful of pasta “just in case,” or roasted enough potatoes to feed a medieval army. Maybe it’s optimism, maybe it’s habit, maybe it’s panic at the thought of anyone leaving the table hungry. But either way, portion sizes are often more about guesswork than actual need, and that guesswork leads straight to the bin.

Sure, leftovers can be lifesavers. But they can also be a slow march to guilt if you’re not planning to eat them. That Tupperware of rice at the back of the fridge? You swore you’d use it. You didn’t. It now has its own ecosystem.

The problem isn’t just culinary. It’s psychological. We associate abundance with care, with love, with comfort. But when dinner ends with a heaping pile of food scraped into the trash, it’s not comfort, it’s waste.

The fix? Portion with intention. Start small, go back for seconds if needed. Learn what a real serving looks like (spoiler: it’s less than most of us think). And if you do have leftovers, treat them like the bonus meal they are, not an afterthought you forget by Thursday.

Impulsive Shopping

The real cost of that two-for-one deal you didn’t need

It starts innocently enough. You walk into the store for three things, maybe some milk, a lemon, and something vaguely green. Then it happens. The bulk aisle. The “family size” offers. The seductive whisper of “Buy one, get one free.” Suddenly your cart is full of things you might use, could cook, should eat, but probably won’t.

And here we are. You have faith that you’ll suddenly become the kind of person who eats “healthy” three nights a week, or finds a use for six avocados before Thursday (you probably won’t). And when those things go uneaten, they go straight to the landfill, along with your money and good intentions.

The issue isn’t the store, neither is your faith. It’s the lack of a plan. Without a shopping list (and a bit of self-restraint), the supermarket becomes a playground of waste. Promotions aren’t always your friend, especially if they lead you to buy more than your fridge, or your week, can handle.

The solution? Go in with a mission. Shop with a list. And ask yourself, “Will I really eat this?” before grabbing the extra-large tub of hummus. Your wallet, fridge, and future self will thank you.

Misunderstanding expiry dates

This yogurt is not trying to kill you, it’s just misunderstood

Let’s clear something up right now : “best before” doesn’t mean “bad after.” And yet, how many perfectly edible cartons of milk, sealed packs of rice, or half-full jars of pickles have been banished to the bin the second they hit their “best before” date?

It’s a tragedy of confusion. “Use by” (DLC) is the real deadline, especially for meat, fish, and dairy. It’s the food safety line in the sand. But “best before” (DLUO)? That’s more of a suggestion. The manufacturer’s way of saying, “This is when I’m at my peak, darling, but I’m still perfectly fine after.” Think of it like fruit that’s slightly past its prime, not photo-ready, but still totally snackable.

The problem is, many of us treat all dates like ticking time bombs. So we throw away food that smells fine, looks fine, and is fine, just because the calendar told us to.

But breaking rules and trusting your senses is acceptable at times. Open it, sniff it, look at it. Don’t let a printed number dictate your decisions when your nose, eyes, and taste buds are fully qualified. That small shift could save meals, and tons of waste.

Not Knowing How to Use Leftovers or Scraps

Your trash is basically gourmet, you just don’t know it yet

We treat food scraps like second-class citizens. Carrot tops? Gone. Broccoli stems? Tossed. Stale bread? Straight to the bin, like it personally offended someone. But these bits still have plenty of fight (and flavor) in them. They’re not garbage, they’re opportunity disguised as compost.

Leftovers and scraps are the kitchen’s best-kept secret. The stuff that makes magic when you’re too broke, too tired, or too stubborn to go to the store. A hunk of dry bread? That’s the start of croutons, French toast, or a damn good bread pudding. Carrot peels and onion skins? Say hello to the best homemade stock you’ve never made.

The problem isn’t the scraps, it’s that most of us were never taught what to do with them. We see a handful of wilted herbs and panic. We see three bites of pasta and assume it’s useless. But those little bits? They’re gold, if you let them be.

Start small. Freeze your veggie peels for stock. Blend your sad bananas into pancakes. Save your Parmesan rinds. And remember, if it still has flavor, it still has value.

Time to rethink what we call waste

Because changing how we consume starts with changing how we think.

Towards more responsible cooking

Less Pinterest perfection, more fridge-based reality

Cooking responsibly doesn’t sound nearly as fun as, say, flambéing something just for the drama. But it should be. Because real kitchen brilliance isn’t about following a flawless recipe, it’s about making something delicious out of what you’ve got, using every bit, and not making more than you’ll eat.

Responsible cooking is about strategy. It’s portioning like a pro, so you’re not feeding a small army when it’s just you and your dog. It’s knowing that leftovers are future-you’s lifesaver. It’s finally learning how to repurpose last night’s roast chicken into something that doesn’t feel like, well, last night’s roast chicken.

And once you stop cooking like you’re hosting a cooking show and start cooking like you live in a world with limited time, money, and fridge space, your meals get better. Smarter. More personal. You stop chasing perfection and start chasing flavor, efficiency, and the smug joy of making something amazing with what you already had.

That, my friend, is real kitchen power.

The Role of Seasonality, Local Products, and Zero-Waste Habits

The peach didn’t fly 5,000 miles so you could forget it in your crisper drawer

There’s something beautiful about biting into a tomato that actually tastes like a tomato. Not a bland, mealy imposter flown in from across the planet in the dead of winter. Just one, sun-kissed, slightly ugly, glorious tomato from someone’s garden or the farmer down the road. That’s seasonality. That’s local. 

And that’s where better eating, and less waste, begins. When we eat what’s in season, we’re not just getting better flavor. We’re skipping the long-haul trucking, the massive cold-storage facilities, the over-packaging. We’re giving the planet a breather and putting our money where it matters. Into local hands. And yes, we’re also giving ourselves a fighting chance at actually using the food we buy before it turns into science experiments in the fridge.

And then there’s zero-waste. Which sounds intimidating until you realize it’s just a fancy way of saying, “Don’t waste the good stuff.” That sad-looking parsley stem? Chop it. That cheese rind? Simmer it in soup. The apple peel? Dry it, sugar it, snack on it like you invented rustic cuisine.

It’s about paying attention to what we buy, to where it comes from, and to how damn much of it we throw away just because we didn’t think twice.

So next time you reach for that pristine plastic-wrapped mango in January, ask yourself: Is this worth the plane ticket?

Changing How We View “Leftovers” and “Scraps”

It’s not trash, it’s your next great meal in disguise

I’m not sure why, but we’ve come to believe that “leftovers” are a punishment and “scraps” are just trash with a fancier name. Like once food exits its prime-time dinner debut, it’s doomed to die a quiet, moldy death in the back of the fridge. But let me tell you, that’s where the real magic lives.

Leftovers are head starts. A second chance to not cook from scratch on a Tuesday night. That half-pan of roasted veggies? Frittata. That last scoop of rice? Fried rice. Those chicken bones? The soul of a damn good broth.

And scraps? Scraps are just ingredients that haven’t reached their full potential. Lemon zest brightens everything from cookies to vinaigrettes. Parmesan rinds add depth to soup like they’ve been training their whole lives for it. Even beet greens, yeah, the ones you toss without thinking, sauté into something shockingly tasty.

Changing how we see food “waste” starts with ditching the idea that value equals presentation. Just because it’s not plated like it’s about to walk onto a food magazine cover doesn’t mean it’s not worth eating, or celebrating.

Because when you start looking at your kitchen through this lens, something wild happens: you stop wasting, you start inventing, and suddenly, your cooking has soul.

Practical Tips to Reduce Food Waste at Home

Because saving food (and money) starts in your kitchen, not in a lecture hall

Let’s face it, most of us don’t mean to waste food. It just kind of… happens. A forgotten yogurt in the back of the fridge, a wilted herb bunch you swore you’d use. But with a little foresight and a few good habits, food waste can go from a regular guest to a rare visitor.

1. BEFORE SHOPPING

Before shopping, start with the basics: plan your meals (nothing fancy, just what you’ll actually eat), write a smart shopping list, and check what’s already hiding in your fridge and pantry. That way, you’re not buying your fourth bag of rice or letting fresh spinach turn into compost.

2. WHILE SHOPPING

While shopping, shop with your brain, not your cravings. Know the difference between “best before” and “use by”. One’s a suggestion, the other’s a deadline. And don’t underestimate the power of tech: apps like Too Good To Go or Frigo Magic can help you save food (and cash) with a few taps.

3. AT HOME

At home, storage is key. Organize your fridge so everything is visible and in the right zone: cooked food up top, raw stuff at the bottom, condiments in the door. Freeze extras before they become science experiments. And if you’re dealing with hot weather or poor refrigeration, be even more vigilant. Warmth speeds up spoilage.

4. IN THE KITCHEN

In the kitchen, don’t just cook, strategize. Portion properly, reinvent your leftovers, and try recipes that give new life to scraps: banana bread, broth from veggie trimmings, or pesto from carrot tops. A shriveled carrot or sad-looking bread still has plenty to give.

And if you still have too much? Share it. Give it to friends, neighbors, or donation groups. And maybe take a page from rural households, where composting and feeding animals are everyday solutions. Waste doesn’t have to be the end of the line.

While households
hold the fork,
governments & industries
control the menu.

Yes, we can each take small steps to waste less (if you’ve made it this far, gold star for you), but the scale of the problem demands more than individual action. The real weight of responsibility lies with those who shape our food systems, drive production, and influence what ends up on our plates.

Governments and corporations must step up. Not with empty pledges or greenwashed campaigns, but with concrete, ethical solutions that protect both people and the planet. That means reducing waste across the supply chain, prioritizing sustainable farming, and ensuring that the food we grow nourishes rather than harms.

It’s easy to feel small in the vast ocean of food waste, but that doesn’t mean our voices are meaningless. Change often starts with a single ripple, and like the butterfly effect, even a small action in one corner of the world can spark a chain of transformations elsewhere. Part of our responsibility is to speak up, to demand better from governments, industries, cities, and companies, because if no one starts the movement nothing will move at all.

Food waste isn’t just a household problem. It’s a system problem. And systems can be redesigned to feed more people, protect biodiversity, and safeguard our future. Because food belongs on plates, not in landfills.
