How does one manage a household sustainably?
The vast majority of people can be found at least once a week doing a big shop at the supermarket. Product after product goes into the shopping cart, until finally a batch of fresh goods, as well as numerous cans, Tetra Paks, and jars end up on the conveyor belt at the checkout. A significant portion of this shopping will sooner or later end up in the trash: An individual in Europe throws away an average of 7.5 kilograms of food per month. But how does this happen? And how can shopping and consumption be made more sustainable, both ecologically and economically?
Shop, cook, and consume sustainably
For a variety of reasons, an increasing number of people are striving to lead a life that is more sustainable in many aspects. Personal consumption behavior is often the main focus here: With our purchasing and consumption decisions, we actively contribute to regulating the use of plastic and natural resources, determining the use of land, and supporting certain industries.
If we throw away a considerable part of the food we purchase without using it, the balance is not very positive: We have not only unnecessarily consumed a lot of packaging material and indirectly utilized storage space and transportation services, but also wasted food that could have been put to better use elsewhere.
How does the fact of massive food waste fit with the pursuit of a sustainable lifestyle? In fact, very few people consciously decide to buy excess or to leave food unused. This behavior is rather due to a lack of planning: We do not have an overview of our supplies, we buy certain products multiple times, and let others that we have long forgotten rot away in the depths of our pantry.
Are there still pantries?
That there are still pantries today, and that in times when supermarkets offer a comprehensive range almost around the clock, they are not just a fringe phenomenon, became apparent at the latest with the outbreak of the Covid-19 pandemic: Bulk purchases were publicly discussed and more and more people began to stock their pantry for the coming weeks. However, most households do not have a well-managed space when it comes to storage rooms or cabinets. Ask yourself if you really know what food items you have at home right now. Do you check your supplies before every shopping trip? Or do you shop on impulse, ultimately undermining your attempts to live more economically and ecologically sustainable?
You probably have little to no idea what's in your pantry – and you're in good company. It's not uncommon to find canned goods that expired years ago or food covered with a thick layer of mold in the farthest corners of our kitchen or cellar cabinets. Almost weekly, we buy canned goods that we already have in abundance at home. But how can we tackle this problem efficiently?
How you can create order
Perhaps you're clearing out your pantry as part of the spring cleaning to create order. But is that really enough, or is a truly comprehensive inventory management necessary to maintain an overview? And how can this be achieved when hardly anyone has the time or inclination to fill out lengthy Excel spreadsheets or to set up a complicated household and pantry ledger? Fortunately, there are better solutions to keep track of your own stock, to be able to shop strategically, and thus fill the fridge and pantry efficiently and sustainably: Digital tools make it easy to manage pantry storage.
A major organizing action and smaller recordings after shopping are already sufficient for this purpose. Thus, only the barcodes of the stored products need to be scanned and the expiration dates manually entered into the app. As a result, a digital management of the refrigerator and pantry is created, ensuring that it is always clear during the weekly shopping what supplies are available at home. Ultimately, such digitization of the pantry leads to not buying items twice, to food no longer sprinting towards their expiration date under the radar, to less being thrown away, and to saving hard cash.
Based on the inventory management, the app can generate a shopping list that reflects the actual food requirements, not just the assumed ones, so that the personal stock can be replenished or consumed in a targeted manner. The dream of sustainable living no longer needs to remain just a dream.
Is it possible without an app?
Of course, food storage at home can also be made more sustainable and efficient without an app. However, the effort is significantly higher in this case, as inventory lists must be manually maintained and constantly updated. Those who do not own a smartphone or cannot or do not want to use an app for other reasons can, in principle, implement the concept of digital inventory management in an analog way and thus achieve their goal.
It is important to not only check the storage in the pantry sporadically, but to update the inventory list after every purchase and every use. Moreover, without an app, shopping lists must be created by hand again – so the need for groceries must also be constantly determined independently.
In conclusion: There are many ways to achieve a more sustainable pantry
In conclusion, it is clear that there are many paths to a more sustainable pantry. However, what all these paths have in common is that they rely on consistent logging of all available food items in the house. Only through such comprehensive recording can needs-based shopping and consumption be achieved. The new organizational method can be most easily integrated into daily life via an app, but if necessary, it can also be done by analog means. What may sound unfamiliar at first ultimately leads to success: statistically, it is possible to save 7.5 kilograms of food per person per month, in addition to significant savings in packaging, not to mention the positive impact on the climate and on one's wallet.
More clarity when shopping: How Open Food Facts and the Smantry app make nutrition transparent
Many foods look healthy at first glance – but what's really inside them? Are the nutritional values balanced? How processed is a product? And what impact does it have on our environment?
This is exactly where the Smantry-App comes in: It uses the globally open database Open Food Facts, to give you immediate clarity when scanning your items. But what's actually behind the colorful labels like Nutri-Score, NOVA or Eco-Score, that you encounter in the app?
Let's take a closer look at the background.
Open Food Facts: From the Idea to a Global Database
The journey began in 2012 with the founding of Open Food Facts – a non-profit organization that collects, analyzes, and makes food information freely accessible worldwide. The goal from the beginning was to provide consumers with scientifically substantiated information.
What started as a small project has now become a global platform with millions of products. And it is precisely this data that the Smantry-App uses to give you a clear overview directly on your smartphone.
An overview of the most important scores
1. Nutri-Score – how healthy is my product?
Since 2016, the Nutri-Score has been legally established in France – and it has quickly spread throughout Europe.
- A (green) means: very balanced.
- E (red) means: unbalanced, enjoy in moderation.
The rating is based on calories, sugar, salt, saturated fats – but also on positive factors such as fiber, protein, and the proportion of vegetables.
👉 So in the Smantry app, you can see at a glance whether a food item fits into your everyday life – or perhaps should be on the table less often.
2. NOVA-Score – how processed is it?
Not only the ingredients, but also the degree of processing plays a significant role for health. This is exactly what the NOVA-Score (integrated into Open Food Facts since 2018) shows you:
- 1 = unprocessed or minimally processed (e.g., fresh fruit, plain yogurt)
- 2 = ingredients such as vegetable oils, sugar, flour
- 3 = processed foods (e.g., bread, cheese, canned goods)
- 4 = highly processed products ("Ultra-Processed Food"), often with additives, flavors, and industrial processes
👉 With the Smantry app, you can instantly tell if a product is still 'close to nature' – or if it falls into the category of being highly processed.
3. Eco-Score (soon to be Green-Score) – how sustainable is my shopping?
Since 2019, Open Food Facts also includes an environmental assessment: the Eco-Score. It takes into account, among other things:
- CO₂ emissions from production and transportation,
- Packaging and recyclability,
- Origin and seasonal factors.
The rating is – similar to the Nutri-Score – from A (very eco-friendly) to E (less sustainable).
By 2025, this will become the Green-Score, which will take into account even more detailed data and thus provide you with even better guidance for sustainable consumption.
👉 For you in the Smantry app, this means: You can see not only whether a food is healthy for you, but also whether it is good for our planet.
What this means for you as a Smantry user
Currently, you can scan your products in the Smantry-App and view many details. The scores themselves are not yet integrated – but the integration is planned.
This means: Soon you will be able to see not only the nutritional values of a product but also how healthy, processed, or sustainable it is – all directly in your app.
Conclusion: Your Smart Nutrition Compass
The colorful labels are much more than pretty symbols. They are your quick compass in everyday life – whether you want to shop with health consciousness, reduce highly processed products, or pay attention to the environment.
With the Smantry-App you already have strong support for more transparency while shopping. And with the planned integration of the scores, it will become even more valuable – your smart nutritional compass for the future.

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.
