You may not have heard of tantalum, but chances are you’re holding some right now. It’s an essential component in our cell phones and laptops, and currently, there’s no effective substitute. Even if you plan to recycle your devices after they die, the tantalum inside is likely to end up in a landfill or shipped overseas, being lost forever.
As a researcher focused on critical materials recovery, I’ve spent years digging through electronic waste, not seeing it as garbage, but as an urban mine filled with valuable materials like tantalum.
Many elements used in creating electronic devices are toxic in and of themselves, or in the form of nano particle dust. Science articles use words like “can” cause, or “may” cause when it comes to these elements causing harm to biological life by further polluting the already massively polluted environment.
