When I die, I'd like my corpse to be dealt with as...expediently as possible. Whatever's cheapest and ideally has the least impact on other people and the environment. Unless of course it could actually help other people, in which case, take all of my organs, use me as a crash test dummy, use me to study the decomposition process, whatever, and THEN freeze me, burn me, compost me, etc.
It's unfortunate that the death industry in America is pretty much uniformly opposed to these ideas. Promession, or freeze drying, isn't legal anywhere in the country (though Kansas apparently considered it for a while?). Cremation is common enough, but you're still encouraged to spend a lot of money on an urn, if not a coffin and a burial plot and headstone as you would for burial.
Interesting fact in the video below-- if you did freeze dry your corpse and break it up into a fine dust, it couldn't be scattered like the ashes of people who've been cremated because the dust would still be organic material, which....isn't okay, for some reason. But you can totally bury it, and it will enrich the soil for planting.
As for composting, there's a company called Recompose that says it will open a facility in Seattle in 2021. It'll be opening there because Washington is the first and only state to allow human composting. According to sciencealtert.com,
"Once the composting process is complete, family and friends of the departed are encouraged to take some or all of the cubic yard of soil generated per person (amounting to several wheelbarrows of soil), and can use it to grow their own gardens, with remaining soil being used for conservation purposes."
I mean....sure? If you're into gardening, I guess? But really, I won't be offended if you don't. And not just because I'm not around any more to be offended.
