How? Just because you get the right token back doesn't mean you got ashes from the body you asked them to cremate. They could be from any body in the oven with them.
Well I don't think they do cremations in groups like that. If they do then yeah there is no way to know who's ashes, but I would also say theres no way to prove they aren't and really in the end its all just carbon.
It doesn't bother me at all. I don't even really need a bag of ashes back. The memories are important.
I'm set up for my body to got the University because that's the cheapest way to dispose of a body. They tell you that your family can get ashes back but they all get mixed together.
Same here, my body goes to the local ned school. They'll return to he ashes if you want, but I don't care. I cleared it with my sister before signing the forms because she does care about cremains etc. Apparently the university has a memorial garden where they spread the ashes.
