well.....
Its not too politically correct these days,
but - years ago - dead whales have been towed well out to sea, and dispersed with copious amounts of Dr Nobel's rapidly expanding bait.
or, dragged ashore and turned into meat meal for stock feed, and blood and bone type fertilizers.
I'm pretty sure option #1 is frowned upon due to tree hugging latte sipping hippy types[collectively known as sooks] being incredibly noisy whingers and spoilsports,
and option #2 is illegal due to anti-whaling legislation banning the use of dead whales - no matter how they became bigger and stinkier than usual.
