Reduce food waste - facts & figures + tips
How much food is actually wasted in Germany, Europe and the world?

Every year, around 1.3 billion tons₁ of food are thrown away worldwide. That's more than a third of the food produced worldwide. Food waste is a massive problem. To make this tangible, I'm now going to show you some facts & figures about food waste in Germany, Europe and around the world.

Food waste in Germany

In Germany, we actually manage to throw away 18 million tons of our food. This corresponds to around one third of the food consumption in Germany of around 54.5 million tons.₂ Here are more facts & figures on food waste in Germany:

  • 1,127 t of food we lose per hour
  • More than 2.6 million hectares of land are farmed to end up in the garbage can
  • 800,000 t of food goes into the trash unopened and untouched
  • Every German throws away the equivalent of about €300 worth of food every year₃.
  • 48 million tons of greenhouse gases are emitted for nothing
  • 39% (7.23 million t) of food waste is caused by the end consumer
  • About 5% (0.98 million tons) of food waste is due to crop losses
  • Approximately 60% (18 million tons) of discarded food occurs from producer to bulk consumer - This food is lost along the value chain
  • 19 t of food is lost per minute

Food waste in Europe

Food waste in Europe deals with about 88 million tons per year.₄

  • About 173 kg of food is thrown away per person
  • Dutch have the largest share (512 kg) of food waste per capita
  • Slovenia (72 kg) has the smallest share of food waste per capita
  • 5% of food waste is due to commerce
  • 12% of food waste is caused by the restaurant industry
  • 30% of food waste go to agriculture & processing.
  • 52% of food waste is attributable to private households

Food waste worldwide

Globally, food waste comprises about 1.3 billion tons. This corresponds to about 30 - 40 % of the food produced annually.

  • Approximately 180 - 190 kg of food is wasted per capita
  • Every day per capita consumed 2000 kilocalories (and harvested 4600 kilocalories)₅.

Consequences of food waste

Food waste has consequences for the environment and society
Growing food is hard work and ecological and also ethical consequences

As you can see from the facts & figures, food waste is gigantic. But which Effects and consequences does the negligent handling of the food produced actually have? We divide them into ecological and ethical consequences₆:

Ecological consequences of food waste

The fact that we throw away one third of all food produced is responsible for around 3.3 gigatons of CO2 emissions. After the U.S. and China, global food waste is therefore the third largest climate polluter. Food production requires valuable resources (e.g. arable land, Water, fertilizer, Energy, processing services and transport), which we have of course senselessly wasted with every food thrown away. However, not only production, but also utilization and removal result in resources and high costs. Agriculture is responsible for nearly 70% of all endangered species and we actually waste about a third of all food produced. This food waste simply has incredibly far-reaching consequences for our environment and must not be allowed to continue.

Ethical consequences of food waste

When we throw away food, it doesn't just have consequences for the environment. Food waste also impacts our society. We know that we throw away about a third of the food we produce, yet there are also about a billion hungry people on our planet. It is incredibly disrespectful behavior to throw away a large portion of our own food while people in other places are struggling to survive and need that very food. By buying massive amounts of food and eating much less, the price of that food also goes up. Even a more conscious purchase of each individual, can reduce food waste and also mean positive effects for the world population.

Food waste causes

Reduce food waste - facts, causes, consequences and tips
Food waste has various causes - From production, to trade, to the end consumer.

Around 60% of the food wasted in Germany alone is lost in the course of the supply chain. Food waste is caused by the fact that food has to be sorted out due to immaturity, pest infestation or diseases. Here I would like to give you a small list of some possible, main Causes of food waste show

Causes of food waste in production:

  • Food was harvested unripe
  • Pests have infested food
  • The food has diseases
  • Inadequate transport facilities
  • Storage capacities not sufficient
  • Cooling possibilities limited (after harvest and during processing)
  • Poor hygiene

Common causes of food waste in retail:

  • Sorting out unsold, perishable products
  • Deviation of shape, color and size
  • Special offers & special prices

These are the causes of food waste in the home:

  • Lack of purchase planning in the household
  • Best before date is mistaken for use by date
  • Lack of stock planning
  • Incorrect storage

In Germany, by the way, food is thrown away because...

  1. the expiration date has passed or the goods are spoiled (84 %)
  2. too much food was purchased (25%)
  3. because the package was too big (19%)
  4. the product does not taste / does not deliver what it promises (16%)

The causes of food waste are manifold and, in sum, a huge problem. But what can each and every one of us do about it? To answer this question, I have written down my best tips against food waste.

16. tips against food waste

Now here's the full broadside of good tips against food waste. With these 16 measures you can reduce your personal food waste.

1. it is called MINIMUM shelf life until...

Since we can get any food anytime, we tend to throw it away one day after the best-before date. But food can usually be enjoyed for much longer, because the date only gives an indication of when the food may no longer be edible. To be able to reduce food waste, you should simply take a close look at the food and estimate the shelf life yourself.

2. leftovers for soups & smoothies

Schmeißt du zufällig braune Bananen oder matschige Kiwis und Tomaten weg? Es gibt keinen Grund dafür. Weißt du wie du diese Lebensmittelverschwendung reduzieren kannst? Indem du diese Essensreste z.B. für Suppen oder Smoothies nutzt. Diese Lebensmittel sehen vielleicht nicht mehr so schön aus, dennoch sind sie ja genießbar. In einer Tomatensuppe oder einem selbst gemachten Smoothie aus Bananen und Kiwis weiß doch niemand, wie die Früchte zuvor aussahen. Und es schmeckt wie immer. Lebensmittelverschwendung reduzieren? Check!

3. take food from the restaurant

If you don't quite make your restaurant meal, that's no reason to throw that food away. To be able to reduce this kind of food waste, just have your leftover food from the restaurant wrapped. Usually, you'll get Styrofoam packaging. If you want to make it plastic-free, just take a stainless steel can with you to dinner. So if you know yourself well, you can prepare this wonderfully 😉.

4. bought too much? Invite friends!

If you've bought too many potatoes, mushrooms, carrots or spinach, that's no reason to throw away the excess food. Instead, simply invite your friends to cook and eat together to reduce food waste. In the same way, you can also just have a plastic free party or even ask your neighbor if he would like to have the food. This is one of many important tips against food waste.

5. throwing away crooked food is nonsense!

Do crooked carrots or potatoes taste worse? Of course not. Nevertheless, the average consumer is used to beautiful fruits and vegetables and gives crooked, ugly foods a wide berth. Unfortunately, these are therefore usually thrown away. To be able to reduce this food waste, we should buy these very crooked foods. I am a real fan of Etepetewhere you can get discarded food at a good price. An absolute win in the fight against food waste.

6. use apps against food waste

At the bakery or in restaurants, throwing away food is completely normal. Cool that there are apps that can help you reduce this unnecessary food waste. One of them is Too Good To Go. In this app, excess food and surplus food are offered for sale for a cheaper price. This app gets consumers and vendors to massively reduce food waste and throw away less food.

7. buy regional and seasonal foods

In this case, of course, the food waste does not happen directly in your home, but you can still reduce the general food waste. Prefer regional and seasonal foods, because they are not damaged during the often long transport from abroad and can therefore be sorted out. In addition, you can Purchase of regional products also expect a longer shelf life, and suppliers know exactly what has happened to the food so far. Buying food regionally and seasonally is a small adjusting screw in your head, but one of many important tips against food waste.

8. store food properly

Foodstuffs differ from one another and must therefore be stored differently so that they can be kept for as long as possible. Some foods last longer in the refrigerator, others must be stored in the light. Here, for example, are a few tips to make your food basically last longer:

  • Such natural beeswax cloth use instead of cling film
  • Potato and fruit crates (line with paper and store one on top of the other; also suitable for fruit)
  • Dry vegetables (e.g. chopped mushrooms, zucchini and tomatoes)
  • ... there are thousands more cool options!

9. pre-plan shopping against food waste

What food do you still have in stock at home? What do you want to cook today? Just answer a few questions like these and be sure which foods you really need. Only then you go off, to ideally plastic-free shopping. This will make your wallet happy and you can reduce your personal food waste.

10. eat up provides good weather!

Another of many good tips against food waste is, as grandma used to say, "Eat up and you'll have nice weather!" - In addition to nice weather, this is how you manage to reduce your food waste. You should only cook as much as you can and want to eat. Learn to judge your hunger better. Of course, you often have a little food left over after cooking. But why should you throw that food away? Keep it in the fridge instead. Many dishes can also be easily freeze plastic free.

11. preserving & freezing food

If you've bought too much groceries or can't make it all at dinner, you can simply boil down or freeze the rest of the food. If the strawberries are getting too soft, why not make some delicious strawberry jam and freeze it for later? There are so many ways to reduce your food waste.

12. buy food consciously (psychology)

This tip against food waste is primarily about your behavior when shopping. In the supermarket, for example, the art of advertising psychology ensures that you usually put more in the shopping cart than you want. By shopping consciously, however, you can reduce your food waste. I can give you the following tips against food waste when shopping in the supermarket:

  • Trade shopping cart for shopping basket (or burlap bag): There is much more space in the shopping cart and this tells your subconscious that something is missing. This is simple psychology and if you know it, you can reduce your personal food waste.
  • Special offers especially reconsider: Bulk discounts (XXL packages, 3 for 2, etc.) may seem cheaper at first. But if you buy too much as a result, you may also throw away some food. Again, think and shop consciously. This is one of the most important tips against food waste.
  • Buying "almost expired" food: If you know you're going to cook or eat them today, you can simply buy foods that expire promptly and are often marked down. So you also reduce the food waste of the supermarket. Because with high certainty the food would have ended up in the trash.
  • Buy only what is on your shopping list: The classic, well-considered shopping list is, in my opinion, the safest way to make sure you don't buy too much. Buy exactly only what you wanted to buy.

13. say NO to throwing away food and YES to increasing food!

Why would you throw away seemingly superfluous foods when you can simply multiply them. Ginger is one such example: If you simply put ginger on the windowsill, the plant will multiply by itself. Or if the potatoes are already sprouting, you can just plant them and get new potatoes. We have become so comfortable that planting already seems so far away. Yet it's natural, cheap, and helps you reduce your food waste. Here is another article about Healthy plants to grow yourself.

14. completely recycle food

Of course, this is not always possible, but it is a direct measure to reduce your personal food waste. Example broccoli: Many cook only the florets of this food, but the stalk tastes just as good! You can also eat the apple completely. If you want to reduce your food waste, you should simply eat everything that is edible in a food.

15. inspire others against food waste

You know the problem of food waste very well, at the latest after this article. Use your knowledge and your personal attitude to inspire others. Online and offline. On social media like Facebook, Pinterest or Instagram, you can reach a lot of people in one fell swoop. Talk to your friends at home about food waste, too. Simply advocate for less food to be thrown away. You'll make a difference.

16. foodsharing against food waste

At Foodsharing you share food with each other instead of throwing it away. On everyone can offer surplus food and also order it. I personally love the concept of foodsharing, as it allows everyone to reduce food waste and save a lot of money. And the idea is growing and growing. The more that join in, the better we can reduce food waste. Here is a short video that explains the principle of foodsharing in detail.

Reducing food waste is incredibly easy!

The fact that we throw away more than a third of our food, although it is urgently needed elsewhere, is inconceivable. But just such facts and figures, the causes and also the consequences for the environment and society are known. I hope that my tips against food waste will help you personally to throw away significantly less food. I am looking forward to your comments with your questions, your own experiences and of course your tips on food waste.

  2. Thank you for this article! As energy experts, we celebrate every contribution to food rescue. Because whoever saves food, as you write at the beginning of the article, also saves valuable energy. We just did an interview about this on our blog with food rescuer Daniel from the association Shout Out Loud e. V.. Daniel goes into more detail about the energy aspect and explains, for example, which foods require a particularly large amount of energy to produce and how this affects the carbon footprint. He also explains at which points in the production chain energy is needed at all.
    Have fun continuing to save food and save energy!

  4. Hi Christoph,
    It is an interesting but also miserable topic. Have 38 years ago made an apprenticeship as a food vendor, and even then we had to dispose of food. At that time, however, we still had the pig bucket that was picked up twice a week, is no longer allowed today. The problem was mainly the customers who always had to test the goods for ripeness with their fingers. Sometimes I would have loved to throw these people out of the store on edge. Unfortunately, it is not much different today than it was back then. As for the producers, a large amount of the field directly disposed of to keep prices high, I find the biggest mess.
    Keep up the energy for your project and greetings from Switzerland Peter

    1. Hello Peter, thank you for your comment. What do you mean by "disposed of directly from the field" and why?
      Stay clean,
