Old ships, railroad cars re scrap metal
Awl --
Been watching History channel, and the scuttling of big-assed ships. Also, railroads, NYC Subways, go thru big expense to properly prep/clean old cars, to dump them in the ocean for coral reefs, etc. Now, if coral reefs are that important, OK..... But, if not, why go through all the expense to dump scrap in the ocean, when these mega-tons of steel could be recycled? With much less expense and chemical waste ito prep/cleaning, etc.? Esp. on military ships, where armor can be 15" thick!! And on railroad cars, where just *one* wheel is 700++ lbs of high quality alloy steel. Usually 8 wheels (4 wheels per "truck", two trucks per car), but sometimes more. Just curious. -- PV'd |
