Who knew your morning coffee could help save the planet? Scientists just found that used coffee grounds can pull up to 98% of nasty metals like lead out of dirty water. Instead of tossing those grounds, they can be turned into powerful, eco-friendly filters. Even raw coffee waste works for metals like copper and zinc! Imagine cleaning up water pollution with something you’d normally throw away. Coffee just got even cooler. #Food #EcoFriendly #Sustainability
