Making compost in a zero gravity environment

Space suit upgrade ideas.

NASA is offering a 30,000 dollar bounty to the right idea that helps mitigate human waste in space suits for 6 continuous days.

Maybe some genetically modified Black Soldier Fly grubs could live in a backpack compartment and convert body toxins into something more safe with the added bonus of space compost.

I think they are not so worried about dealing with the waste as moving it away for delicate anatomy, their current solution is a diaper, so the threshold for improvement is low.

Collecting the solid waste would be the hardest part, I imagine.

In a vacuum environment wou could simply let the moisure boil off. That would reduce the volume and kill most if not all bacteria.
