A solution turns green as it pulls cobalt from a spent lithium-ion cathode. A Rice University laboratory is developing an environmentally friendly method to recover valuable metals from used batteries.

Solution to Recycle World's Batteries

They literally have a solution to deal with the glut of used lithium-ion batteries.

Blocks of hexagonal-boron nitride foam treated with polyvinyl alcohol proved able to adsorb more than three times its weight in carbon dioxide. The reusable material was created at Rice University.

Foam Soaks Up Carbon Dioxide

The highly porous foam can be tuned for use in air filters.
