In my novel, the many moons of Jupiter and Saturn have been colonized, but I'm running into some logistical problems - namely, waste disposal. My first instinct was to dump it on-moon; while this is fine on places like Io, for others, like Europa, it won't work due to environmental reasons. So, would colonists be able to launch their waste into the hearts of Jupiter and Saturn and let the immense gravity do all the dirty work?
Some clarification by request: For purposes of ease-of-story and narrative, sub-light drives are common, but not very cheap. Admittedly, the exact math and speeds elude me, but I would put it comparable, price-wise, to commercial shipping on Earth today (expensive, but cost-effective). The waste, by and large, would be the everyday waste of colonists - any place with radioactive or dangerous waste would have long ago stopped worrying about standards of living, similar to a coal mining operation today.
