While it seems logical that many restaurants have already begun to reap the benefits of installing onsite worm composting operations, airports may not be the first place people would think of to have such systems in place. The Charlotte Douglas International Airport will change that fact when they open a $1.1 million recycling center in February 2012, to include a vermicomposting system that will use 300 pounds of worms to chow down on up to two tons of airport patron waste per day.
