Philadelphia has just gotten a little cleaner, a little greener, with the help of the BigBelly. The BigBelly (I love typing that!) is a solar powered trash compactor used in place of traditional waste bins, which allows for more trash to be collected and reduces the number of pick-ups necessary from garbage trucks, thereby reducing fuel usage and emissions. They even send a text message when they are full, so that pick-ups can be routed to where they are needed most, saving even more time and energy. Brilliant!
