Our rivers have been contaminated with medications for years. The EU has a solution: let the pharmaceutical companies pay

When we read that one of the great environmental challenges of our time is the state of our rivers, our imagination travels directly to the fecal waterindustrial pollution or, lately, microplastics. In what we don’t usually think It’s in the medications. But the problem is real and the European Union is determined to solve it. How can medications ‘contaminate’? Drugs (whether for medical or veterinary use) have a very long life after consumption. And, inevitably, a good part of the medications end up being expelled from the body and entering wastewater. From there, despite the efforts of treatment systems, they reach rivers, lakes and seas. An increasingly solid scientific consensus. Although it is difficult to get a complete idea of ​​the impact of this type of pollution on the environment, the investigations that are appearing They make it clear that it is very far from being an anecdote. In fact, at least 631 pharmaceutical substances (human or veterinary) have been found in more than 71 countries on five continents. Many of them, at levels higher than those considered safe. In 2022, the CSIC analyzed 258 rivers and, after cataloging the Manzanares River as “the most contaminated by drugs in Europe”, warned that we were in the face of “a global threat to the environment and human health.” “Global threat (…) to human health”? Are we not exaggerating? In the case of antibiotics, to use an example we are all familiar with, this is clearly seen. We have been warning for years that the abuse of these medications leads to the emergence of multiresistant bacteria. That’s true on the consumption part, yes; but also in the part in which enormous quantities of them are dumped into nature every year (with the problems that this causes for ecosystems and the risks that it poses). Why is this news now? Because the European Union wants to take action on the matter and, as Oriol Güell explainsis introducing a whole new battery of measures in the renewed Directive on Urban Wastewater Treatment. The goal is to “reduce the compounds discharged into the environment by more than 80%”; the environment, the introduction of a whole series of “quaternary treatments” (ozone, activated carbon, new membranes, etc…) in the treatment systems. The problem? that the EU wants them to pay the affected industries: above all, pharmaceuticals and cosmetics. An idea that the sector has not liked. As expected, the application of the “polluter pays” principle in these terms has not pleased the sectors involved. Above all, because of the costs. According to the employers’ associations of both sectors, the application of the European directive would lead to an increase of about 500 million euros in Spain alone. And, beyond the expected conflicts between companies and administration, it is true that the movement is paradoxical. Not because it is not reasonable to charge the costs of water treatment to those who produce them; but because just a couple of years ago, Europe announced its intention to bet on having drug factories on the continent (and thus reduce its dependence on international supply lines). Towards a culture of responsible drug use. Be that as it may, in the end we always return to the same thing: the drug industry is heading straight into a very complex crisis in which health, economic, environmental and cultural issues intermingle so as not to lead us to a dead end. One in which we risk our health, the future and our lives.

A solar solution to supply the world with 22 Energy TW

A recent Ember report explained how Europe had eliminated coal as an energy source in 2024 and gave way to renewable energies, such as solar. In fact, in the same analysis, Spain registered a continuous increase in photovoltaic generation, reaching 21% of its electricity almost double that the European average (11%). So far everything is fine, but this boom of the solar is carrying that alternatives for the installation of panels in other surfaces, such as aquatic. International investigation. A study group, led by Carlos D. Rodríguez-Gallegos, has evaluated The state and potential of floating photovoltaic facilities (FPV) worldwide. For this analysis they have used the largest global database that collects the information of 1,142 commercial FPV systems from 2022. In addition, they took the geographical references of reservoirs, which cover a total area of ​​more than 2.2 million square kilometers. The object of study is to analyze its implementation and performance, in addition to studying advanced configurations such as bifacial panels, inclination angles and monitoring systems. The investigation had contributions from researchers from the You will be Singapore and from the National University of Singapore (NUS), as well as the Polytechnic Higher School of the Litoral de Ecuador, the Polytechnic University of Hong Kong, the Concordia University of Canada and the University ofokin of Australia. Asia, the leader. Almost 90% of the installed floating solar capacity is in the Asian continent and China leads it with almost half of the accumulated capacity. This world predominance is due to favorable, ambitious objectives focused on renewable energy and regulations designed to support the expansion of FPV. Although Asia leads the development of floating solar panels, Africa is also exploring this technology. Zimbabwe advance with a 250 MW plant In the Kariba dam, projecting to reach 1 GW. In Ghana, A 5 MW system In a reservoir it will be expanded to 15 MW, while Cape City, in South Africa, has completed several smaller projects. With abundant sun and limited water resources, Africa seeks to meet your energy needs through these initiatives. Take advantage of water areas. The installation of photovoltaic systems on aquatic surfaces has presented different benefits, according to the study. First, optimization of limited space in areas with scarcity of earth. In addition, FPVs help reduce the evaporation of water in reservoirs and to maintain the temperatures of the lowest solar panels, improving their efficiency. On the other hand, this technology avoids related conflicts about land use. To give an example, in the Swiss Alps, They have demonstrated that these facilities can prosper even in adverse conditions, reaching higher performance regardless of altitude. The study results. From the analysis that the average size of the FPV has increased in the last ten years of 0.09 MW in 2013 to 1.40 MW in 2022, and, in parallel, the average power density has gone from 82 W/m² at 123 w/m². Researchers have identified optimal configurations to maximize electrical performance, such as the use of solar monitoring systems and bifacial panels, which capture the reflected light, thus improving energy generation. In economic terms, FPVs have proven competitive. For example, the project director has signed up for an Indian initiative that achieved a cost of installation of just $ 0.41 per watt, which reinforces the economic viability of this technology against other renewable energy options. However, these facilities also face certain challenges such as the initial cost can be very high by infrastructure. In addition, technology adaptability to different bodies of water (sweet or salty) and logistics complexities can also increase costs. Looking at the high seas. Looking ahead, the research team plans to explore FPV applications on the high seas, investigating its energy potential, innovative designs and the challenges that costs and maintenance present. According to its estimates, covering only 10% of the surface of 249,717 continental reservoirs could generate a capacity of up to 22 TW, sufficient to satisfy all world consumption of electricity and up to 5% of the global water demand.
