Free Write - Colorado School of Mines Turn Food Garbage to Glass!

In Golden, Colorado, the Colorado School of Mines engineers found an alternative to digging into mountains for minerals.  They started mining the minerals from food waste.  They were able to turn putrid banana peels, eggshells and rice husks into crystal-clear glass.  Now, they are investigating other muck.  In their lab, they rigged up a cooking system that starts at a fridge, students donated garbage.  This garbage is ground in blenders, dried, then pounded into fine white powder containing pure minerals, such as silica and oxides, which are typically used in mining mined using heavy diggers and toxic chemicals.  An oven heated to 3,000 degrees melts the silica powder into a molten red substance that when it is poured into the molds morphs to glass.  Now, the US Government has registered a provisional patent on this!

  2. Wow, this sounds really cool! It always amazes me that someone can figure something like that out. Sometime, with all the news articles out there, it seems like our world is doomed environmentally, but stories like this certainly provide a glimmer of hope for us!
