As part of a science project, a group of students have built a solar powered bin that sorts out all the trash that is dumped into it. The bin called Recycl-o-sort has three sensors that can distinguish between glass, plastic and aluminium containers or non-recyclable trash. A turntable passes each of the trash items through these sensors and then chucks it into the corresponding storage space. So after assorted butter cookies we now have assorted trash!
