Composting Animal Bones
Most animal bones, meat and seafood can be composted, albeit at a much slower rate than other items. It is recommended that only small bones are added into the HOTBIN and carcasses carefully broke up into smaller pieces to speed up decomposition.
Composting Shells
Theoretically shells can compost down over a long period time. We would not recommend adding these to the HOTBIN because the shells would need to be broken into smaller pieces, probably with a hammer, which would result in hazardous sharp fragments.
