Dive Summary:

• In 2010, more than 75 million tons of food packaging went into U.S. landfills, leading researchers to investigate how to cut down that number.
• Two Harvard scientists have developed a membrane-like material that is completely edible and made from calcium and magnesium ions.
• Another interesting aspect of this development is that the membrane can hold anything from liquid soup to ice cream and it can even be flavored.
   

From the article:

"Last month, a German-owned “common sense” supermarket chain, Billa, posted a picture of some bananas on its Facebook page. Harmless, right? Except for some reason, the bananas were peeled then packaged in Styrofoam trays wrapped with cellophane. It wasn’t the best PR move for a supposedly “environmentally conscious” company.

The images spread around the Web rapidly. Billa’s Facebook page was so overrun with angry comments that it was temporarily taken down. A spokesman for Greenpeace called what Billa did with the bananas “just madness.” Quickly enough, the company had apologized for its “one off” error."
