After An Atheist Dies

[Dropship]

I was wondering, what if an atheist doesn't want a funeral or other religious practice after he or she (or other pronouns) dies? Is there any nonreligious practice with dead bodies?

Here in Britain you simply tell the undertakers what you want the vicar to say (or not say) at your funeral.
I think you can even not have a vicar if you don't want one.
You can go a step further and keep the costs way down by arranging to be buried or cremated in a cardboard box like a kentucky fried chicken which is how I'd prefer it for myself.
The vicar will say something over me like "Dust to dust, ashes to ashes, cluck-cluck-cluck"..

PS- Would anybody fancy a "space burial" like John Hurt had in 'Alien', wrapped up in a bedsheet and whooshed out of the airlock?
"Anybody wanna say something?" asked Dallas, but nobody did.
If I'd been there I'd have said something like "He was a good kid"..
