What food waste has to do with climate change

Destruction of nature

With every food item that ends up in the trash, valuable resources such as farmland or water are also wasted. After all, the food was produced anyway, even if it wasn't eaten. Similarly, the product was packaged and transported to supermarkets or discount stores - which in turn means COโ‚‚ emissions. Because the transport routes are often very long. Fruit is imported from South America by plane and vegetables from Asia. By the way, very often by plane - which is particularly harmful to the climate.

Moreover, a large portion of our food is no longer produced in Germany, let alone locally. A prime example is the palm oil plantations, for which people are displaced from their land and rainforests are cleared and/or slash-and-burned. This releases the carbon stored in the jungle soils and large amounts of greenhouse gases enter the atmosphere. Biofuel made from palm oil is also not climate-friendly, by the way. To be more precise, it is three times as harmful to the climate as gasoline made from crude oil (Source: Regenwald.org).

The destruction of the rainforest also leads to the disappearance of many rare animal species such as the orangutan or the Sumatran tiger.

What can I do to prevent food waste?

Of course, not everyone has to become a vegetarian or vegan to do something about climate change. It already helps to pay attention to the small things, such as opting for local and seasonal products when shopping and focusing on organic. Unpackaged food also helps to protect the climate. Fortunately, there are more and more zero-waste stores in many cities and villages. But the most important thing is that food no longer ends up in the trash because it has gone bad.

For instance, I try to be creative with recipes to use up leftovers, like vegetables such as tomatoes and peppers. Sometimes that results in a casserole or a stew. Moreover, I always try to buy only as much perishable food as we can actually consume in a week.

PantryApp against food waste

Our founder Matthias launched the SpeisekammerApp primarily because he wants to declare war on food waste. The app is designed to make food management as easy as possible.

Using the app is incredibly simple. Just scan the products with the barcode scanner and record the expiration date and storage location - that's it - and you'll get the nutritional information right away. Food items that are not in our database can be entered manually. The app works on iOS, Android, and through the browser. Data is synchronized in real time across different devices.

From anywhere, you can also check, for example, which groceries are still at home, how much there is, and where the expiration of the best-before date is imminent. This helps you avoid duplicate purchases and use up products before they spoil. By doing this, you can actively prevent food waste and at the same time do something against climate change.

The best kitchen tools to turn leftovers into delicious dishes ๐Ÿฒโœจ

Hand on heart: Each of us has them โ€“ those little leftovers in the fridge or pantry that somehow never get properly planned for. But it's exactly these remnants that can often be turned into the most creative and delicious dishes! All you need are a few clever kitchen tools that make the work easier and get the best out of your ingredients.

Here are our favorites:

๐Ÿฅฃ 1. The powerful blender

Smoothies, soups, dips โ€“ a good blender transforms leftover vegetables, fruit, or even bread into a new dish in seconds. Perfect when bananas are a bit brown or the vegetables no longer look crisp.

๐Ÿ”ช 2. A sharp chef's knife

Sounds simple, but a really good knife is worth its weight in gold. It allows you to cut vegetable and meat scraps precisely and quickly. Moreover, cooking is just more fun when you have the right tools.

๐Ÿณ 3. A cast iron skillet

The all-rounder in the kitchen: fried potatoes made from leftover boiled potatoes, frittatas with yesterday's vegetables, or crispy bread cubes from stale bread โ€“ everything tastes twice as good in a cast-iron skillet.

๐Ÿฅ• 4. Vegetable Peeler & Grater

A modest tool with a big impact: grate carrot leftovers, turn zucchini into noodles, or finely shred cheese remnants. With a peeler and grater, you bring variety to your leftover cooking.

๐Ÿฅก 5. Storage Containers & Screw-top Jars

Without proper storage, nothing works. You can keep leftovers fresh, transport them, or even prepare them for the next meal prepping. Tip: Jars are also great for serving small amounts in style.

๐ŸŒฑ 6. Kitchen Scale

It's practical to know exactly how much is left over, especially with leftovers. This way, you can adjust recipes and avoid waste.

๐Ÿฅ„ 7. Personal Blender

The little brother of the blender โ€“ perfect for soups or sauces right in the pot. When only a small amount needs to be processed, it's super convenient.

How Smantry additionally helps you ๐Ÿ“ฒ

With the Smantry App you can not only keep an eye on your supplies, but soon you'll also be able to discover recipes for your leftovers. This way, you'll immediately know which tool to take out of the cupboard to save your food and create something new.

๐Ÿ‘‰ Because good tools and the right app are the perfect combo to combat food waste.

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.

Sharing supplies together โ€“ why the Shared Economy is now moving into the kitchen

The concept of Shared Economy has long been more than a short-term trend โ€“ it's changing our everyday lives. More and more neighborhoods, shared apartments, and community projects are discovering how practical it is to organize groceries together and manage supplies transparently.

Why sharing supplies is becoming increasingly popular

  • Save on costs: Bulk purchases become cheaper when more people participate.
  • Save space: Not everyone needs their own package of rice or pasta.
  • Better organization: Digital tools make it easy to see what is available.
  • Experiencing community: Food brings people together โ€“ as does camping together.

From the flatshare to the neighborhood

Especially in shared apartments or families with multiple households it pays off to keep a communal stock of supplies. But neighborhood projects or small communities are also recognizing the added value: shopping, storing, and using together.

How Smantry helps

This is where Smantry comes into play:

  • Community Feature: Supplies can be managed collectively.
  • Transparency: Everyone can see which items are available.
  • Efficiency: Duplicate purchases are avoided, leftovers are used up in time.

๐Ÿ‘‰ The shared economy doesn't stop with cars โ€“ it moves right into your kitchen. With Smantry sharing supplies becomes easier than ever.
