The Colombian innovator turning air pollution into raw materials
Colombia faces one of the most severe air pollution challenges in Latin America, with 99.3% of its population living in areas that exceed World Health Organization guidelines.
Against this backdrop, Colombian entrepreneur Mariana Pérez has developed a solution that tackles both environmental and health crises – earning her a place among the top ten innovators in the Young Inventors Prize 2025, awarded by the European Patent Office (EPO).
At just 27, Pérez is the founder of Ecol-Air, a startup behind a technology that captures not only carbon dioxide but also nitrogen dioxide and sulphur dioxide – gases linked to respiratory illness. Unlike traditional carbon-capture devices, her system mimics the human respiratory system, using artificial 'bronchioles' and 'alveoli' to absorb pollutants from the air.
'My invention is just like a giant vacuum that captures a volume of air and puts it through this system and breaks down all the contaminants into a tank,' she explains. Installed on chimneys or as free-standing air purification stations, the machine treats polluted air and processes the toxins into biodegradable polymers – materials that can be repurposed into sustainable packaging or industrial components like tiles and bags.
'We can transform the pollutants and contaminants into raw materials that can be used,' says Pérez, 'I decided to create this machine because people ignore that air is as important as water.'
Pérez's interest in air quality began when she was just eight years old. 'I remember watching rain wash residue off my dad's car and wondering where all that black dust went,' she recalls. That childhood curiosity grew into a passion for science, leading her to participate in school science fairs and eventually develop early prototypes of the machine that would inspire Ecol-Air.
'There were moments in my journey when I doubted myself,' she admits. 'But I believe all scientists need to realise that, while we can create incredible solutions for the planet, health and people, scaling our projects and turning them into businesses is what gives our inventions a real future. We can't stop at just having an idea; we need to develop it further.'
After facing initial scepticism from manufacturers, Pérez offered to install her units for free in large factories to demonstrate their effectiveness. Sumicol was the first to adopt the system commercially, followed by Incolmotos Yamaha. In 2021, the first air treatment plant using her technology opened in Girardota, processing 70 tonnes of air daily with an 82% efficiency rate, according to company data.
Now living in New York, Pérez is preparing for global expansion. 'Right now I'm focused on a global expansion because all the world needs to purify air,' she says. 'We are focused on trying to put our machine in large industries. Our invention is in the Commercial Readiness Level9 stage, meaning that it is fully functional, fully operative and, of course, tested, and ready to be adopted by the market.'
With her innovation, Pérez is directly addressing multiple UN Sustainable Development Goals, including SDG 3 (Good Health and Well-being), SDG 11 (Sustainable Cities and Communities), and SDG 13 (Climate Action). As one of the EPO's 2025 Tomorrow Shapers, she's helping reshape how we think about pollution: not just as a problem to contain, but as a resource to transform.

The Slovenian innovator transforming microchip manufacturing
Data centres are the digital world's powerhouses – but they come with a heavy environmental cost. Globally, they consume an estimated 460 terawatt-hours (TWh) of electricity each year, equivalent to the energy needs of 153 million homes. Without intervention, their carbon footprint could reach 3.2% of global emissions by 2025. Teja Potočnik, a 26-year-old Slovenian researcher, is working to change that. Her invention – an automated nanomaterial integration platform – optimises the manufacture of advanced semiconductor devices, otherwise known as chips. These advanced chips, in turn, power the servers and hardware that run today's data centres. By enabling the production of more energy-efficient chips, her innovation directly contributes to reducing the massive energy consumption of data centres worldwide. 'The problem we are solving is the ever-increasing demand for faster, more efficient and more powerful microchips. This is because of the demand of AI, quantum computing and data storage users', Potočnik explains, 'Our invention can help with the manufacture of more energy-efficient chips using nanomaterials, which means that there can be enormous energy savings.' This pioneering project has earned her a place among the selected innovators honoured at the 2025 Young Inventors Prize, awarded by the European Patent Office. As chips become smaller and more powerful, manufacturers are turning to materials like graphene, carbon nanotubes and quantum dots to push performance boundaries. But while these nanomaterials hold immense promise, integrating them at scale remains a major challenge. Potočnik's invention, LithoTag, addresses that bottleneck. By embedding nanoscale markers into semiconductor wafers, the platform enables precise alignment and integration of nanomaterials with high repeatability. This bridges the gap between laboratory research and industrial manufacturing. 'The industry cares about reliability, replicability, and integration into manufacturing processes,' she says. 'No matter how good a technology is, it holds little value if it can't be scaled.' Originally from Slovenia, Potočnik moved to the UK to study materials science and engineering, where she says she 'fell in love with nanomaterials'. Potočnik co-founded the startup Nanomation while completing her PhD in nanofabrication at the University of Cambridge. With backing from Cambridge Enterprise, she and her team filed a patent application and began exploring commercial partnerships with chip manufacturers. But it's not just about business: Potočnik's work directly supports the UN's Sustainable Development Goal 9 – Industry, Innovation and Infrastructure – by improving the scalability of sustainable microelectronics. It could lead to more energy-efficient consumer devices and data centre infrastructure, with widespread environmental benefits. Looking ahead, Potočnik envisions her technology becoming standard in advanced electronics manufacturing. 'The real advantage of our technology is that it can be applied to any material and any sort of electronic design, so we really hope to become the industry standard in integrating nanomaterials into advanced circuits,' she explains. Beyond the lab, the young Slovenian innovator hopes her story will encourage others to pursue bold, scalable ideas that can make a difference. 'To all the inventors who are thinking about realising their new idea, I would say just have an open mind and be brave,' Potočnik advises.

Meet the inventors helping farmers keep fruit fresh longer
Each year, over one billion tonnes of food go to waste while hundreds of millions still face hunger. For Ugandan entrepreneurs Sandra Namboozo and Samuel Muyita, this crisis has a personal dimension. Growing up in farming families, they witnessed first-hand how quickly harvested fruit could spoil before reaching markets – leaving farmers with major losses and little return for their hard work. Motivated by this challenge, the pair developed a solution rooted in both science and sustainability. Their invention, a biodegradable sachet made from plant-based compounds, can extend the shelf life of fruit by up to 30 days. This breakthrough has placed them among the top ten selected innovators – called Tomorrow Shapers – of the Young Inventors Prize 2025, awarded by the European Patent Office (EPO). 'What brought us together was the fact that both of us came from an agricultural background,' says Muyita. 'We had identified and related with a problem that was at hand, so it was easy for us to team up and come up with a solution, which is Karpolax.' Their company, Karpolax, uses volatile organic compounds (VOCs) extracted from plants like cloves, lemongrass, eucalyptus and wintergreen to slow the ripening process and protect fruit from mold and bacteria. Unlike conventional synthetic preservatives, these sachets are natural, safe, and designed to release active ingredients gradually and specifically for different fruit types. In pilot tests conducted with Uganda's National Agricultural Research Organization, mangoes stored with the sachets stayed fresh for 33 days – triple the shelf life of untreated ones. The product has since been tested on bananas, apples, and oranges, and new versions are being developed for pineapples, berries, and capsicum. 'It's basically a sachet that we put in fruit boxes during storage or delivery,' Namboozo explains. 'It releases an active ingredient that helps preserve the fruit for an extra 30 days.' The duo met while studying at Makerere University in Kampala and launched Karpolax in 2020. Their vision was clear from the start: make scientific innovation directly useful to the people who need it most. 'Farmers are one of our biggest customer groups,' says Namboozo. 'We wanted to use our knowledge and technical skills to develop something that would not just end on a paper in a lab but really be used by somebody.' By 2023, their product had reached over 100 farmers, 20 exporters, and 250 market vendors. With plans to expand across East Africa—including Kenya and Rwanda—the team is scaling up production and product lines. Their work directly supports the UN Sustainable Development Goals, particularly SDG 2 (Zero Hunger) and SDG 12 (Responsible Consumption and Production), by offering a low-cost, eco-friendly way to reduce food loss and increase farmer incomes. 'Starting from zero, you need to source for that funding yourself,' Muyita recalls. 'We had some supervisors from the university who supported us and made us feel confident that we could succeed.' With growing recognition and real-world impact, their ambition is only increasing. 'Our vision is to be the world's leading fruit and vegetable preservation company,' says Namboozo. And for other young innovators, Muyita offers a simple message of encouragement: 'Believe in yourself. When you believe in yourself, believe in the fact that you have what it takes to make it. You will indeed make it.'

Marie Perrin pioneers rare earth recycling
Rare earth elements (REEs) are vital to everything from smartphones and laptops to wind turbines and electric vehicles – but extracting them comes at a steep environmental cost. Mining one tonne of REEs can generate up to 2,000 tonnes of toxic waste, including radioactive material. French-American chemist Marie Perrin is offering a cleaner solution. At ETH Zürich, she developed a fast, scalable process to recover europium from discarded fluorescent lamps – without the pollution of conventional methods. 'Today, I'm working on bringing to market a technology that I developed during my grad studies on the recycling rare earth elements,' Perrin says. 'They're in your phone, in your computer, and in a lot of green technologies, like wind turbines and electric cars.' 'We have a solution [...] to source these metals from the very waste we produce,' she says. The innovation earned her a place among the top ten Tomorrow Shapers in the European Patent Office's 2025 Young Inventors Prize. The patent-pending process begins by dismantling lamps to safely extract phosphor powder and remove mercury. The powder is dissolved in acid, then combined with sulphur-based molecules that trigger a redox reaction. A golden precipitate forms, rich in europium, while other elements like yttrium remain in solution. The solid is filtered, treated with ammonium oxalate to regenerate the extractant, and finally transformed into usable europium oxide. The method also reduces the need for toxic solvents and allows closed-loop reuse of chemicals. 'Our invention allows us to separate these elements more efficiently. And we do it from waste so that these critical metals are not thrown away,' she says. Born in the US and raised in Toulouse, Perrin was drawn to chemistry from a young age – not least because both her parents are scientists. ''My mum is a chemist, and early on, she shared her passion for chemistry, which really guided me in my studies afterwards,' she says, looking back. Perrin's PhD at ETH Zürich began with work on water purification rather than rare earth separation, but a shift came early in the project when, together with PhD supervisor Professor Victor Mougel, Perrin 'discovered that the molecules that we were using could be used for rare earth separation'. With support from ETH's Technology Transfer Office, Perrin filed a patent application, published her findings in science journal Nature, and co-founded the Swiss startup REEcover with Mougel and longtime friend Maria Pujos. In spite of REEcover's sustainability credentials, it has not all been smooth sailing. 'We reached out to many companies but struggled to make an impact at first,' Perrin recalls. 'When we began to make contacts, we realised that many industries do not have power over their supply chain.' Initially focused on lamps, REEcover is now expanding into recovering rare earths from magnets used in electric vehicles and electronics. The team is running proof-of-concept studies to adapt the method to other waste streams, aiming to push industry towards circular models. For Perrin, this is not science for science's sake. 'Our generation faces many challenges, from global pandemics to climate change,' she says. 'If you have an idea, be bold, be creative and keep pushing the boundaries of human knowledge.'
