If you absolutely must get rid of bones and cartalige of the turkey, boil it down into bone broth and strain the remaining bits off to break down in the trash, or (if the bones are soft enough.) mash it down into a bone "brick" to crumble and throw outside safely where it won't hurt any animals that finds it.

How small is safe? I wouldn’t want to risk it. Internal splinters in a small critter can be deadly. Just trash them unless you’re going to put the bones through a blender.
@CJLavoie When it comes to boiling down the bones, I'm talking smooshable between your hands level of softness. The smaller bits can be dangerous yes, but straining them off should help reduce the threat to the wild if you compost or throw out the remains of the bone broth. I don't own a trash compactor unfortunately, but I do reuse everything I can until all that's left is the smallest bones that can't be reduced to harmless moosh.
@PaganMother Sounds like you’ve thought it through. I wonder if a dash of vinegar would help soften them more? Anyway, hope you had a wonderful holiday!
@CJLavoie Yep! It should yeah, if you hope to reserve the bone broth for future use, it might help keep the broth for longer as well though I would be careful about how much vinegar you add to it. Maybe a half cup to several cups of water and bones should help soften them up for easier disposal.
