It is the quickest and easiest way to preserve food. But who has ever thought about how to store food properly in the freezer and what the benefits are?
Good advice is not expensive
We thought about this question and compiled our tips for you here. To use the freezer even more effectively, it is important to defrost it regularly. We'll show you how.
Of course, the sustainability aspect also plays a major role in this topic. Sustainability through energy efficiency. This is because a well-filled freezer with few air gaps requires less energy. This keeps the temperature constant. Frozen food retains its temperature very easily due to its consistency. More electricity must be used to cool empty space. You should therefore opt for square boxes that are easy to stack. Well-labelled and sorted by category, you can find the food you want in just a few easy steps. With a self-created barcode, the app can support you even better and you can immediately see how long the stock in the fridge will keep.
People often ask themselves how long frozen food will keep. This question is justified. There are different recommendations outside in the world wide web. Of course, just because the specified period has been exceeded does not mean that it is spoilt. Just test it out. You'll be surprised how much longer food can be eaten safely.

Defrost correctly!
Has a thick layer of ice already formed in the fridge? Then it's time to defrost it as soon as possible. This will save you electricity and give you more space for more food. We show you how to do it easily.
- Clear out food.
- Switch off the refrigeratoror fridge-freezer.
- Clear out all shelves and compartments.
- Lay out kitchen towels on the floor. These will catch the water.
- The ice will melt much faster due to the vapour spreading. This is also our tip! There are two options here:
Slow: Melt the ice slowly by opening the freezer or refrigerator doors wide open.
Fast: Place a pan of hot water on the base of the appliance and close the door. The ice will melt much faster due to the vapour spreading. This is also our tip!
- Depending on how badly the freezer compartment is iced up, defrosting will take some time. If you use our tip, you can check after just 15 minutes to see if the icing has come off. In the meantime, you can wash out and dry the shelves or drawers.
- Try to remove the ice carefully to avoid damaging it. If you still need to scrape it off, use a wooden spoon or plastic scraper. Pour the scraped ice cream into a bucket.
- Wipe and away. It is best to clean the icebox with a sponge and wipe all areas with warm rinsing water. Don't forget the seal! Afterwards, wipe all surfaces with a dry cloth. Otherwise the water will freeze and ice will form again very quickly.
- Refill. Now put all the food back into the freezer. This saves electricity when you switch the freezer back on, as it does not have to cool down to the standard temperature all by itself.
- Power on -now everything is super clean again and ready to go at the touch of a button.
As you can see, it's very simple and takes very little time. So let's go and declare the ice the war.
Have fun, Kira

New laws on food waste in Spain
Spain has recently passed a groundbreaking law to combat food waste. This law requires all actors in the food chain, from producers to retailers, to implement specific plans to prevent food loss.
Key provisions of the law:
Obligation to donate surplus food: Supermarkets with a floor space of more than 1,300 square meters are now required to form partnerships with non-profit organizations to donate surplus food that is still fit for consumption. These donations are exempt from value-added tax.
Offer of packaging for leftover food: Restaurants and bars are required to provide their guests with free, reusable or recyclable packaging so that they can take home uneaten food. The aim is to raise consumer awareness of food waste and encourage them to take leftovers with them.
Promotion of the sale of products with approaching expiration dates: Retailers should offer products that are nearing their expiration date or have aesthetic defects at reduced prices to encourage their sale and reduce waste.
Hierarchy of priorities for dealing with surplus food: The law establishes an order for handling surplus food. Priority is given to human consumption through donations. If this is not possible, the food should be used for the production of processed products. The last options include using it as animal feed or for energy generation.
Sanctions for violations:
Companies that violate the provisions of the law can expect fines ranging from 2,000 to 500,000 euros.
Critique and Outlook:
While the law is considered an important step in the fight against food waste in Europe, there is also criticism. Some voices argue that the strict framework of sanctions could disproportionately burden companies and that the law does not sufficiently address the role of consumers, who are responsible for a significant portion of food waste.
Nevertheless, the law is seen as a significant advancement in reducing food waste and promoting a more sustainable awareness in society.

Sustainable barbecue β how to make your BBQ eco-friendly & delicious
The sun is shining, the evenings are getting longer β it's finally BBQ season again! But even when barbecuing, you can save a lot of COβ, avoid waste, and even be really creative. In this blog, we'll show you how sustainable grilling works β without sacrifice, but with lots of flavor and responsibility. π±π₯
1. Shop regionally & seasonally
The foundation for sustainable grilling starts with shopping. Instead of relying on grill classics that have traveled far, it's worth taking a look at what's available locally:
- Seasonal vegetables such as zucchini, bell peppers, corn, or mushrooms are perfect for grilling.
- Fruits like peaches or pineapples add a sweet touch to the grill.
- Regional cheese or Tofu from European organic soy are great alternatives to imported or meat-heavy products.
π‘Tip: Use the Smantry App to see what ingredients you have at home and what you can conjure up with them.
2. Less (but better quality) meat
Meat has a high carbon footprint β but you don't have to give it up entirely. Pay attention to:
- Organic quality
- Species-appropriate husbandry
- Regionality
Alternatives such as marinated cauliflower, halloumi skewers, or homemade lentil burgers are not only climate-friendly but also really tasty.
3. Grill without aluminum foil
Aluminum foil is harmful to the environment β and can even be hazardous to health when heated. Instead, use:
- Stainless steel grill pans
- Grill baskets
- Banana leaves or corn husks as natural packaging
- Reusable skewers made of stainless steel or wood
4. Upcycling Recipes: Smartly Repurposing Leftovers
After barbecuing, there's often something left over. Here are a few ideas:
- Grilled vegetables can be turned into a salad or wrap the next day.
- Bread leftovers are turned into crispy croutons.
- Fruit leftovers are perfect for a fruity iced tea or sorbet.
The Smantry App helps you keep track even after the BBQ β and avoid wasting food.
5. Conscious Grilling: Ambiance over Mass Production
Sustainable grilling also means: Less is more.
- Eat consciously, instead of preparing extra-large portions
- Plan your shopping efficiently and without excess with the app
- Avoid single-use products like plastic cutlery or paper plates β a BBQ is more enjoyable with nice dishes anyway!
In conclusion: Sustainable grilling is easy β with the right planning
With a little preparation and creativity, your barbecue will not only be delicious, but also good for the environment. And the best part: You don't have to make any compromises. The Smantry App helps you to use everything you already have β for less waste and more enjoyment.

Food waste in international comparison β Who does what?
π«π· France β Legally Against Waste
France is considered a pioneer in the fight against food waste. Since 2016, supermarkets have been prohibited from throwing away edible food. Instead, they must donate or repurpose it. Schools and universities are increasingly focusing on educational programs for sustainable nutrition. As a result, France is now among the countries with the lowest proportion of wasted food in Europe.
π°π· South Korea β Smart Waste Fees
In South Korea, households pay for their food waste by weight β through RFID chips in garbage bins or special garbage bags with barcodes. This financial incentive has led to South Korea now recycling 95% of its organic waste. The system is combined with extensive educational efforts and the promotion of biogas and composting facilities.
π©π° Denmark β The movement comes from below
Denmark relies on the power of the community. Initiatives such as "Stop Spild Af Mad" (Stop Food Waste) have sparked societal debates. Moreover, supermarkets like Wefood exclusively offer food products past their best before date β and at low prices. The acceptance among the population is high, and schools are actively incorporating the topic as well.
π―π΅ Japan β Tradition Meets Technology
In Japan, food waste is also culturally associated with a strong sense of shame β this helps. Additionally, there is a focus on innovation: companies use AI for better inventory planning or apps that indicate when food should be consumed in the household. Bento shops also use data to precisely adjust their offerings to the daily demand.
π©πͺ Germany β Between Movement and Potential
Germany is making progress: Initiatives such as Too Good To Go, Foodsharing or apps like the Speisekammer App / Smantry help to reduce waste in everyday life. Legally, however, it is not as advanced as France β although the pressure is increasing. 40% of the wasted food occurs in private households β this shows how important individual solutions are.
π What we can learn from it
Whether through smart technology, legal requirements, or social movements: the fight against food waste needs many perspectives β and all are important. The good news: every single step counts.
With the Speisekammer App / Smantry you can start right at home β with smart pantry management, reminders for expiring food, and clever shopping planning.
