Food waste is not just a problem for restaurants — airports also have to deal with piles of this kind of garbage.
At one of the nation's busiest airports, Charlotte Douglas International
in North Carolina, each passenger generates half a pound of garbage on
average per visit. But instead of just sending all that trash to the
landfill, Charlotte has taken a different approach. It's the first
airport to put worms to work dealing with trash.
A dozen employees pluck out recyclables and sort through aluminum, plastic and more, so passengers don't have to do the sorting in the terminal.
In
the four months since this operation got under way, trash going from
the Charlotte airport to the landfill is down an impressive 70 percent.
Recyclables are crushed, baled and sold for cash. There are shirts
sorted and laundered and donated, and plastic cups collected. (The
shirts come from people who toss clothing when they suddenly discover
their suitcases are too heavy.)npr
