Mercadona and the rest of the supermarkets spend tons of paper on receipts that no one reads. Now they want to change it

by

You go to the supermarket, you buy a couple of things (just enough for dinner), you go to the checkout, they give you the ticket, you put it in your pocket and you leave with the bag in the direction of the parking lot. Pure routine. Our daily bread. If the employer’s retail achieves its objective, there is one element of that scene, however, that will change radically. Which? That ticket that you will end up throwing away without even reading it. What has happened? Every year supermarkets print millions and millions of strips of paper in which in many cases only a handful of articles appear, so they end up in the garbage can without anyone having even looked at them. It is a waste, a waste of resources. For chains like Dia, Lidl or Mercadona, but also for the environment. So Asedas (Spanish Association of Distributors, Self-Service and Supermarkets) has had an idea: they want us to start printing receipts only when the customer requests it. What do they want? The news I advanced it on thursday theEconomist. Asedas has proposed to the Government that it slightly tweak the regulations that regulate tickets so that they are no longer printed systematically. That does not mean that they are no longer issued or that the customer no longer has a receipt that clarifies what they have purchased and how much they have been charged. The change would focus on support. The idea, clarifies Ignacio García, head of Asedas, is “that the ticket continues to be generated electronically for control purposes, but that it is printed on paper at the consumer’s request.” That is, the user can request the physical or digital ticket. Right now, remember theEconomistthe regulations provide that supers deliver the receipt in two ways: either in paper or digital format. What’s happening? Since not all clients are in favor of handing over their data (including email) to the chains, in the end they have no choice but to print it. Not only that. The employer’s data They show that many of the times we go to the supermarket we buy only a handful of items, so the receipts show small transactions, for low amounts that we do not even review. Result: those papers end up in the trash as they are printed. It is not even strange for the customer to reject them when the cashier offers them to them. Is it that serious? “Our companies have been confirming for years that, in about a third of operations, the ticket is abandoned at the checkout line,” confirm Garcia. It is not surprising if we take into account the data on the shopping basket managed by Asedas. According to their estimates, 30% of the operations registered in supermarkets respond to almost urgent visits, during which we take home at most four products and spend less than 10 euros. In 60% of cases, purchases involve between five and 25 products with average tickets of between 10 and 50 euros. Only the remaining 10% actually respond to large purchases. In practice, the fact that all operations end up reflected in a receipt means that the supers generate about 5 billion tickets that require the use of almost 4,500 tons of paper and a million-dollar expense. Is it important? Beyond the millions of receipts that are printed each year and the cost that this entails in tons of paper and euros, Asedas’ proposal is interesting for at least two reasons. To start with who throws it. Asedas presume to be “the first food distribution business organization in Spain” and cover 19,200 retail stores and 495 wholesalers. Between your partners Companies such as Mercadona, Lidl, Aldi or Dia appear. Another key is that its idea is in line with what is already done in other European countries. For example, in 2023 France said goodbye to the generation of tickets by default precisely because of the amount of paper it consumed. That doesn’t mean they no longer exist, but they must be requested. In the Netherlands, Switzerland and Sweden there have also been changes related to the generation of receipts. In Spain itself, some large chains they take time moving towards the digital ticket.

the dark history of mercury in the fashion industry

by

When we think of Alice in Wonderland one of the most recognized characters is ‘Mad Hatter’‘, an eccentric character with a top hat and a label that says 10/6. And although it may seem that the author of this story wanted to give that characterization to the famous rabbit, the truth is that all hats at that time had a serious problem which made them look too much like the classic rabbit. What’s behind. And the reality behind the character is much murkier and less colorful than in Disney or Tim Burton films. The expression “mad as a hatter” was not a literary invention in this case, but a quite popular medical diagnosis for the timesince for centuries the hat industry suffered a silent epidemic that led to serious neurological damage. and the culprit it was mercury. The ‘carroting’. To understand why hatters fell ill, we must look at how the felt was made between the 17th and 20th centuries that would give rise to hats. The raw material was usually rabbit, hare or beaver fur, and in order for these furs to become a high-quality, rigid and durable felt, they were subjected to a chemical process called “carroting”. This name came from the orange color of the carrots that the skins acquired when treated with a hot solution of mercury nitrate. But logically it was a death trap for the workshops of the time, just as collect NIOSH historical archives. Security issues. Although there are now strong regulations regarding safety at work, if we look back it was not like that. And the treatment was carried out in a poorly ventilated space, which caused mercury vapors to be released when the acid mixture was heated with the skins. By not being able to escape through any ventilation slits, the professionals who were constantly working with the skins ended up inhaling the mercury vapors. It was not a one-time accident, but rather a chronic exposure that accumulated in the body and directly attacked the central nervous system. A new reality. Although in the popular culture of the time the profession was directly related to being completely crazy, the truth is that current toxicological reviews indicate that chronic mercury poisoning produces a devastating and very specific clinical picture. And the hatters did not simply become ‘eccentric’, but also had Danbury tremorswhich are uncontrollable muscle spasms and intentional tremors that prevented fine movements. But there were also personality changes making pathological shyness, extreme irritability, depression and emotional lability the norm. The countries took note. Logically, this is something that had to be regulated to guarantee the safety of workers. France was one of the pioneers by prohibiting the use of mercury in the manufacture of hat boxes in 1898, but in Anglo-Saxon countries the industry was quite resistant to change. And the resentful. In the United States the process remained in force for decades. In this case, it took World War II for the tables to turn and it was not until 1941 when the use of mercury was definitively abandoned in key states such as Connecticut. But the reason was not the safety of its artisans, but rather that the war required a large amount of mercury to manufacture detonators, which forced the hat industry to look for substitutes such as hydrogen peroxide, as detailed in the industrial records of the time. Alice’s Hatter. It’s tempting to think that Lewis Carroll designed his character as a textbook case of erethism, but the evidence suggests otherwise. A classic analysis published in BMJ puts the dots on the i’s in this case, pointing out that Carrol knew the popular expression “mad as a hatter”, since he lived in a time where hatters with tremors were a visible social reality. However, the character of Alice in Wonderland It doesn’t quite fit the medical profile. The Hatter in the book is hyperactive, talkative, euphoric and a lover of riddles. Mercury erethism, on the other hand, is characterized by extreme shyness, social anxiety, and depression. It is likely that Carroll took the figure of the hatter and the idiom to create a caricature, but the identification of the character as “mercury poisoned” is a reading that we have made a posteriori.

The hypermarket is quite mortally wounded in Spain. There is an absolute winner: the Mercadona model

by

For years the plan was to take the car, go to the hypermarket on duty and spend a couple of hours walking through its aisles to collect everything we needed and a few other things that we could find because there was almost everything there. is passing away by leaps and bounds. From the boom of the hypermarket to its decline. It was the 90s when they became popular, but there has been a change in purchasing and consumption habits that were catalyzed by the pandemic. The 2025 data from the consulting firm NIQ (former Nielsen) collected by El País They speak of a share of 10.2% of total sales in Spain. And last year it grew by 1.2% unlike the previous year, where it fell by 2%. The problem, in addition to its small piece of the pie, is that the majority of food distribution channels in Spain grew more. The heirs of hyper. These Mercasa studies date from spring 2025 cited by The Economist where they reflect that supermarkets already concentrated 91.8% of the commercial surface in the state. And it is not the only one: the other alternative is proximity formats. It is true that the NIQ data shows that the medium supermarket (between 300 and 799 square meters) fell more than the hypermarket, but its share is four points higher. The small supermarket (less than 300 square meters) and the large supermarket (between 800 and 2,500 square meters) are the big winners: the former rose two tenths with a sales increase of 9.1% and the latter did the same by nine tenths to reach 57.1% of the market and 7.6% of turnover. Here there is an absolute winner: Mercadona, whose new openings exceed 1,500 square meters and which has also been transforming its 1,600 stores for years to replace the smaller ones. And its strategy is paying off: its share has risen to 29.5% in 2025 despite having 10 fewer stores. The Mercadona effect or how efficiency kills size. This change in trends opens a new battle for proximity: the growth is in the 1,500 square meter supermarket aka the Mercadona model or in the convenience store. Growing no longer means opening more centers, but rather having better centers: it pays more to close 10 stores because you have more efficient stores. On the other hand, last mile logistics is gaining weight: it is easier and more affordable to serve an online order with a network of small stores scattered throughout the urban center than from a distant hypermarket. In addition, the franchise format allows chains to expand their brand without assuming operating costs. The consumer has spoken. The NIQ consultancy reflects clearly this paradigm shift: purchase occasions per household have grown by 11% in 2025 and units per basket have decreased by 7.6%. In short: we buy more times but less quantity, a trend that benefits local stores and penalizes hypermarkets. Kantar’s reading points to factors such as smaller homes, a higher average age, an urban context that favors this type of purchase over American car culture. The chains are moving. The fact that the hypermarket is in decline, reducing its weight in the market, directly affects the operators that exploit this format, such as Carrefour and Alcampo, followed by Eroski and El Corte Inglés. In NIQ figures, the first lowered its share two tenths to 7.2%, the second fell from 3.1 to 2.9% and the Basque chain fell one tenth to 4.3% and El Corte Inglés did the same two tenths, to 1.6%. So they are adapting to this paradigm shift: In Xataka | Mercadona has understood that Spain no longer wants to make its potato tortillas.

For centuries price has been a sign of quality. Generative AI is breaking that rule in dozens of sectors

by

For centuries, price has served as a cognitive shortcut. If something costs a lot it is because, for one reason or another, it must be worth a lot. An Armani suit, Bang & Olufsen headphonesa McKinsey report. The number has always served to convey certain information to us before seeing the product. It was compressed reputation. With the arrival of generative AI, that is ending in many sectors. Today a logo can cost 15 euros or 15,000. And be the same logo. A market analysis can come from a consulting firm with offices on three continents or from a guy in pajamas who knows how to wear Deep Research. The report may be indistinguishable. In fact sometimes the second one will be betterbecause the guy in pajamas understands the sector and the consultant assigned the junior who was free. AI is breaking the link between production cost and final result. Something very similar to what Antonio Ortiz, AI popularizer and former final boss of this house, in “Artificial Intelligence and unlinking effort and result“. If anyone can generate in minutes what previously required teams, weeks, and invoices with many zeros, price no longer communicates much about quality. It’s starting to be noise. and this will force a signal migration. From ‘how much’ to ‘who’, to ‘how’ or ‘why’. The questions that will matter are going to be “who signed this?”, “what process followed?”, “what human decisions were behind it?” That is, the process will become the product. It is already beginning to be seen with design studios that They obsessively document any iterationor consultancies that not only sell you the deliverable but also also access to the reasoning of their partners. More and more we are digital artisans who charge for showing how we work and not only for what we deliver. AI has made production almost free, so we are being flooded with digital content of all kinds, so scarcity shifts to criteria. Knowing what to ask for, what to discard, what makes sense and what doesn’t. to good taste. AI can do almost anything, and what it can’t, it will learn next year. Deciding well what to do and what not to do is still expensive. There, for the moment and luckily, there is no shortcut.

The time it takes to get to a highway anywhere in Spain, on a revealing map

by

Faced with the pressing housing problem in Spain In large cities, one of the simplest solutions for those who can afford it is to leave stressed centers such as Madrid or Barcelona in search of more accessible municipalities and properties. How much? It depends on your budget, what your work is like and what the destination location offers you in such objective terms as services and infrastructure. And there is one essential to move: the distance to a main road. I speak with knowledge of the facts: this was a key factor when choosing a municipality to buy an apartment months ago. My new location has direct access to the highway and getting from there to my trusted padel club in Pamplona is 10 minutes longer than doing it from my old apartment, located in the center of the Navarrese capital. Although it is not ideal, my pocket has appreciated it and the sacrifice is profitable for me. Now, having chosen an idyllic municipality in the Navarrese Pyrenees would have been a very bad idea in terms of mobility (although bucolic on days like today). That was my personal decision, but given the prices, I know that I am not alone: ​​from buying in the capital to doing so in a municipality in the province there are price variations of up to 131% in Madrid or 126% in Álava, according to the latest Idealista study that collects La Razón. Because if the price of the property in Villagónadas de Abajo is the lowest in the province but it is where Cristo lost his lighter, already such. Well yes: the price differences are abysmal and the communications are too. An x-ray of territorial inequality and Spanish orography This map created by Digital Cartography With data from the Ministry for the Ecological Transition and the Demographic Challenge, this is evident. The cartography collects the minutes by car to a highway or highway from a good part of the Spanish state (if there are no this type of roads, as happens in Ceuta or Melilla for example, then they do not appear) with information from 2022. To see everything in a more intuitive way, they have used the colors of the traffic light, where green is what can cost you up to 20 minutes and red goes from one hour to 133 minutes in the maroon areas. The access time to a highway or highway in Spain. Digital cartography with data from the Ministry If we superimposed a physical map with a demographic one we would find a clear diagnosis of red zones in critical areas such as the Asturian massif and the Pyrenees, the muga with Portugal (especially in Zamora, Salamanca and western Extremadura), the Iberian System and the maximum expression of “Empty Spain” in the south of Teruel, the north of the basin and areas of Guadalajara or the Betic Systems. We know that in communications Spain It is a centralized state with Madrid as the nerve center and the lines of these main roads, although they do not appear on the map, can be intuited. Without going any further, it is not too difficult to imagine where the A-2 goes to Barcelona or the A-6 to A Coruña. That is the first clue as to why we find such an uneven map: the radial network model, which leaves enormous gaps in peripheral areas that are not linked to large state/European corridors. Obviously the extreme orography of the Pyrenees or the Iberian System makes construction difficult on a technical and economic level (it is not that it is not possible to lay out viaducts or tunnels, it is that it makes the cost skyrocket), but the Average Daily Intensity mandates: for a public work to be approved there is a cost-benefit analysis and if an area has a low population density, the ADI is low, making it difficult to justify the investment. On the other hand, there are environmental restrictions: some of these red zones coincide with national parks or protected areas. In this scenario, obtain a Environmental Impact Statement (mandatory in projects of this magnitude) is an impossible mission. The small print. Something that I greatly appreciated when I returned to Navarra is that there is no traffic… compared to Madrid. The rush hour for leaving work or school may be noticeable in a few minutes of delay, but it is light years away from the traffic jams that I have had to suffer in return or bridge operations when I lived in the state capital. Because although in Madrid almost everything is green, in practice those minutes correspond to a distance traveled respecting the limits of the road and assuming fluid traffic.

In 1901, a Spanish man had one of the ideas of the century: invent the remote control before television

by

Televisions change, technologies change, but there are interactions that last despite the passage of years, decades and even centuries. An example of this is the remote controller, which has historically allowed us to interact with devices from a distance, although what we currently know is very different from the first concept of remote control. Although televisions did not become more common in the last decades of the 20th century, the concept of the remote controller appeared much earlier. Specifically, in 1901. And a fact that you may not know is that one of the pioneers of the remote control was a Spaniard, the engineer Leonardo Torres Quevedo. The controller anticipated the televisions The history of the remote control dates back, as we said, to the first years of the last century. In 1903, the inventor, mathematician and engineer Leonardo Torres Quevedo (1852-1936) conceived, built and patented the first remote control in history. He called it Telekino, and as one might thinkIt is far from the controls for televisionsand other devices we see now. Miniaturization was not a reality until much later and the Telekino took up an entire table. Telekino in Abra. Image: Torresquevedo.org Of course, the Telekino was not created with the idea of ​​controlling televisions remotely, which in reality did not become a reality almost until the incorporation of the cathode ray tube (withthe pushfrom Telefunken and other manufacturers). The idea was to control airships without anyone being in danger in the tests, but finally he tried it with boats as they recalled in the written edition ofThe Countryin 2007, when the Institute of Electrical and Electronics Engineers (IEEE) recognized the invention by including it in its official list of milestones in the history of engineering. It was the first time that a Spanish creation became part of this list, in which we find inventions by Benjamin Franklin, Alessandro Volta and Guglielmo Marconi among others. Telekino, as you may have deduced, comes fromTV(from ancient Greek, “far”, meaning “at a distance”, “remotely”) andkinein(also from the Greek, “movement”), by the way. IEEE Recognition Plaque. Image: YouTube We already talked about Telekino inXatakaprecisely because of this historical recognition, also to remember that at the time it was not highly praised. In fact, Torres Quevedo himself would abandon the project as he did not receive sufficient support. The valuable legacy of Torres Quevedo One of the prototypes of the Telekino is located in the Torres-Quevedo Museum, in the Higher Technical School of Civil, Canal and Port Engineers of the Polytechnic University of Madrid. And thanks to a short (virtual) visit to that museum for the centenary of one of the Spanish engineer’s inventions we can discover more of them, also very relevant. Torres Quevedo is credited with nothing more and nothing less than the first Spanish airship, as well as the first ferry suitable for transporting people (or in other words, an open cable car for people). The invention was patented in 1887, and it would not be until 30 years later when it materialized, being launched on Mount Ulía in San Sebastián in 1907. Compensation also came in the form of international export, since the system reached neither more nor less thanto Niagara Falls. Thus, the callSpanish AerocarIt continues to operate today in the well-known region and celebrated its centenary in 2016, having completed more than 10 million transports without recording incidents. Torres Quevedo was also a precursor of modern computing with his Ajedrecista, considered the first chess computer game, and the electromechanical arithmometer, a calculator accompanied by a typewriter, a precursor to digital calculators.

China urgently needed a train station, so it was built in nine hours with 1,500 workers and 23 excavators.

by

Anyone who has done a work at home will have already experienced firsthand that they know when it starts but not when it ends, something that happens in domestic works and that we also see from time to time with public works. And large infrastructures take time, although we have seen real records such as this 10-story building in just 29 hours. Of course, in China. Precisely there, in the city of Longyan in the southeast of the country, is where they have made a train station overnight. Literal. And although the work is a milestone in 2026, the reality is that this reform in record time took place in January 2018 and that left Elon Musk with his mouth openwhich had no qualms in stating that “China’s progress in advanced infrastructure is more than 100 times faster than that of the United States.” As China Central Television narratedat 6:05 p.m. the station closed and only 17 minutes later the remodeling kicked off in an action that more than a construction seems like a synchronized swimming number until 3:30 in the morning, the time of the end. A kind of “open heart operation” in public works Only nine hours for a project that, although it is true that it was not a new station from scratch, was not exactly small: it consisted of a remodeling and connection of roads between a new high-speed line between Longyan and Nanping and three existing railway lines. Furthermore, they decided to do it at night so as not to interrupt daily rail traffic. Because at 6:22 p.m., 1,500 workers grouped in seven units were executing seven different simultaneous tasks, such as Zhan Daosong tolddeputy manager of China Tiesiju Civil Engineering Group, China’s leading railway construction company. To carry it out, they relied on seven trains and 23 excavators. Thus, while one group installed monitoring and signage equipment, another paved the land. The millimeter precision and rapport is such that Reminiscent of open heart surgery but transferred to public works: with workers distributed over a range of 1.5 kilometers in their assigned places and 23 coordination teams to ensure compliance with deadlines and processes. Something like this is not done overnight, but before the day of truth They did six large-scale drills to prepare. The decision to do it at night has an explanation: not to interrupt the day’s rail traffic because in fact, at 1:56 in the morning they already had the first test train accessing the new station. Because they had also estimated a verification period of three and a half hours in which three other trains accessed the facilities. At 5:53 in the morning the rehearsals were over: K297, a normal passenger train, arrived at the station. As impressive as the speed of the project, which involves enormous planning work and prior studies, was the achievement achieved: reducing the travel time between both cities from seven hours to just an hour and a half thanks to the high-speed train that travels along the track at 200 km/h.
