It is generally not recommended to add bones to a home composting bin.
Bones take a very long time to decompose and may not break down completely in a home composting bin.
In addition, bones can attract pests and animals, such as rats and dogs, which may dig through the compost pile in search of food.
If you have leftover bones that you want to dispose of, it is generally better to throw them in the trash, rather than adding them to a home composting bin.
If you do choose to add bones to your compost, be sure to mix them with a large amount of other types of organic matter, such as leaves and grass clippings, to help neutralize the smell and reduce the risk of attracting pests and animals.
It is important to handle bones with care and to avoid coming into contact with them, as they may contain bacteria that could be harmful to humans.
