Warning over rare metals in gadgets

Modern technology is too reliant on rare materials whose scarcity could drastically set back innovation, a new report has warned. It suggested that as more and more devices are manufactured, supplies of key elements, particularly metals, will be strained. Potential substitute materials are either inadequate or non-existent, researchers said. One scientist called the findings "an important wake-up call". Andrea Sella, of University College London - who was unconnected to the study - tolwebsite The Conversation that it was the first time the issue had been explored in such detail. Researchers at Yale University, led by Prof Thomas Graedel, analysed the use of 62 metals or metalloids commonly found in popular technology, such as smartphones. Troubling It found that none of the 62 had alternatives that performed equally well. Twelve had no alternative, Prof Graedal found. The scope for serious disruption because of material shortages is increasingly troubling technology companies. Rare materials are expensive to extract, and their processing comes with considerable environmental concerns. Please turn on JavaScript. Media requires JavaScript to play. //
