American Antarctic food waste burned in Seattle

I found this article about the burning of the American Antarctic food waste in Seattle interesting.  I knew that all the waste had to be removed from the continent and was done at the end of every summer season, but I did not realize at least part of the trash was taken all the way back to Seattle to be disposed of/burned.  On the one hand it seems odd to transport it so far, but at the same time it is nice that it is not being outsourced to another country to take care of or have to deal with.
