Thanks to @suspended and @deimos for the suggestion!
Hey y’all, I am a basin chemistry engineer for the Department of Energy’s Savannah River Site in South Carolina. Our facility stores spent nuclear fuel from a variety of research and experimental reactors underwater. Our specialty is highly-enriched aluminum-clad fuel, but we have a diverse array of unusual fuels from around the world. A good overview of fuel types can be found here.
My primary responsibility is ensuring the basin water is kept highly pure to minimize corrosion to the fuel, as well as ensure it is free of radionuclides to the extent practicable. I’m happy to answer any questions I can about nuclear fuel, nuclear power, radioactive waste, etc.

Hello Tildes,
I've been doing bokashi composting for pretty much all my vegetable and fruit scraps since last year. Lately, I've been wanting to level up my game and recycle meat scraps and chicken/fish bones as well. That's how I came across these "foodcycler" devices. They basically chop up and dry food scraps in a sealed container. I assume it works much like how industrial composting machines work, except it's scaled way down. At around 300-400 dollars, they're certainly not cheap, and probably generate a lot of greenhouse gasses during the manufacturing process. What's more is, every time you run a cycle, it has to run for 4-8 hours, though the manufacturer says the device is "energy conscious."
I'm trying to assess whether I'll do more harm than good by buying one of these things to convert more of my food scraps. My ultimate goal is to try many different ways to recycle food waste and try to get my friends to try it out as well. Some of them have already shown interest in bokashi composting, but none has actually tried it out (too much work).
Do you think commercial "foodcycler" devices do more harm than good? How should we go about evaluating this?
Edit: I've asked this question on many different places, and it looks like the general consensus is there's no strong need for something like this unless you live in apartments, in a city/town that does not collect food waste. Some believe recycling food waste via the more traditional methods (e.g. bokashi, vermicomposting) would yield better results because the foodcycler would dry up and kill a lot of the bacterial presence, though I believe the dried up scraps can be somewhat "revived" by mixing them in wet soil. Nobody seems to be able to definitively tell whether using the foodcycler would be a net positive or negative, because there's no way to verify its manufacturing process. I may do an experiment on how much power it draws if I get my hands on one in the future.
