Toward safer disposal of printed circuit boards
Printed circuit boards are vital components of modern electronics. However, once they have served their purpose, they are often burned or buried in landfills, polluting the air, soil and water. Most concerning are the brominated flame retardants added to printed circuit boards to keep them from catching fire. Now, researchers have developed a ball-milling method to break down these potentially harmful compounds, enabling safer disposal.
