You can buy either large compostable bags to line the entire bin or use small ones you tie shut and than toss those into the bin.

Also I see they mentioned Bones, that's something your backyard composter won't get hot enough to deal with.

I've seen firemen seriously damage elevators cause they aren't properly trained to open them if something goes wrong. That turns into verify costly repairs and downtime. If I we're a building owner of turn them off than deal with damage.

i dont have an exact answer, but you can look on the website its self
