Lead-acid batteries are a huge environmental problem, especially in the developing world, where recycling rates are low and many people rely on them for household power. In July, a team of MIT engineers reported a straightforward way to recover toxic lead from old batteries to make a new kind of solar cell. One battery can supply enough material to produce enough solar panels to power 30 houses.
So-called reverse vending machines that give you cash for your bottles and cans have been a thing for a few years. Now, people in the United Kingdom, Brazil, and the United Arab Emirates can dispose of their used lightbulbs the same way, using machines that separate LEDs and compact fluorescents from incandescent bulbs. Built by U.K. firm reVend, the machines allow recyclers to remove and recycle the small quantities of mercury and other toxic substances found in fluorescents and some LEDs.
