Startups develop tech to eliminate harmful PFAS chemicals

Innovative startups are working to tackle harmful chemicals known as "forever chemicals" that are produced during the manufacturing of microchips. Companies like Oxyle AG are developing technologies that can destroy these chemicals rather than just remove them from the supply chain. Microchips are essential for artificial intelligence, and the semiconductor industry is growing rapidly, with chip sales reaching about $628 billion last year. However, the production process releases per- and polyfluoroalkyl substances (PFAS), which are linked to serious health issues like cancer and infertility. These chemicals can be found almost everywhere on the planet, affecting rainwater and human blood. Regulators in the US and Europe are beginning to impose limits on PFAS in drinking water. Despite this, many companies are still allowed to release these chemicals without restriction. For instance, a semiconductor plant was found to have PFAS levels as high as 623 parts per trillion in its wastewater. Oxyle AG's technology uses tiny bubbles to capture PFAS molecules in water, breaking them down into harmless substances. The process can reduce PFAS concentrations significantly, making it more effective than traditional filtration methods. Other companies are also exploring similar solutions, emphasizing the need for new technologies to meet evolving regulatory standards. Despite the advancements, regulatory uncertainty remains a challenge for widespread adoption of these technologies. Industry leaders believe that the semiconductor sector has the potential to address PFAS issues effectively. They advocate for improved waste management practices and continued collaboration between industries, governments, and researchers to find sustainable solutions.
