Those whom feel compelled to 'do the right thing' by burying or cremating every humanlike corpse, you shouldn't read further.
Presuming you have no colonist immune to strong mood debuff from butchering humanlike and no joywire installed to compensate for such a debuff, the most practical use for corpses I've found without just burying them or leaving them to dessicate is to build a separate freezer for your corpse-feeding animals (cats, dogs, boars, most especially wargs and cougars, etc.). The great thing is they'll eat even rotten corpses with seemingly no ill effects, so be sure to put a check by 'allow rotten'. Unfortunately for now, colonists will also haul in dessicated corpses which are, unfortunately, useless.
Your colonists would get a mood debuff from entering that freezer, so I think its a really good idea to intentionally have only a single door going in, so the colonists will never try to take a shortcut through there and will only incur a mood debuff when going in there to haul stuff in. I prefer to keep the human corpses in their own room separate from hay, since I expect to haul in hay a lot and don't want to trigger 'Observed corpse' mood debuffs every time a colonist does so ... I tend to build a two-room freezer for animals with the first room (most generally accessible) for hay and rotten animal corpses (rotten animal corpses don't, despite some misconceptions I've seen, cause mood debuffs for 'Observed rotten corpse' -- only rotten/dessicated human corpses do that) and an interior room accessible only through a single door from the hay/rotten animal corpse room just for human corpses.
Since you aren't butchering, you don't get the huge stacking 'Butchered humanlike' mood debuff. And every time your critters feed on a human corpse -- particularly the carnivores such as wargs and cougars whom can't eat hay or kibble -- they won't eat your regular animal meat you use for your colonist meals. And if you play in tougher biomes/difficulty levels, it gives you a bit of a buffer from choosing between your own colonists starving or slaughtering your colony animals because you don't have enough food for your colonists and animals.
A bit of a 'step back' from this, if you're okay with occasionally butchering humans, I like to use human meat and hay on occasion to make kibble (but I try to reserve a couple human corpses as they build up for my carnivores ... I really like cougars as powerful colony defenders that can outrun fleeing raiders) ... that's a win-win if you can absorb the mood debuff for the butcherer and the rest of your colonists, as it really extends the food supply for your colony animals, even for herbivores (all of whom I believe can eat kibble that contains meat, even if they can't eat meat directly, with no ill effects).

) and their corpse has reached the rotted stage, setup a refrigerated zone near your carnivore sleeping area just for rotten corpses (its a bit of a pain I hope gets fixed in a future version -- give it a slightly elevated priority but not as high as your freezer, allow it to accept rotten) and your colony carnivores will chomp them down. Unfortunately, as I previously mentioned, corpses go from fresh to rotten to dessicated very quickly during a Toxic Fallout Event, so you'll have to act quickly if you spot a corpse that's already reached the rotten state -- don't wait for haulers to find it on their own but manually force a nearby colonists to haul that corpse immediately (do this for a regular fresh corpse too!).
