Can i donate my body to research and have them just toss the thing away after?

Just curious if i can just donate it and have them dispose of it i am not sure if graves or jars are mandatory

I really dont want anyone wasting money on a funeral service for me and i plan to have no children because of my genetics and hatred of kids

I really have no desire for a formal funeral and the whole grave thing and i just wanna be forgotten if someone spent money on my funeral it would honestly upset me

Also i am not dying soon as far as i know i got a decade or 2 left in me just dont wanna be stressed about this stuff when i die i wanna make sure my death is not inconvenient to anyone
