说明:  Certain wastes are preferably managed at a community level. Some household items do not decompose and can cause injury if not properly disposed of. For example, neither glass nor plastics can be used in composting, and plastic gives off poisonous fumes when burned. Bones and metal items do decompose, but the process is very slow batteries contain toxic chemicals. Bones, metal objects and broken glass can also be thrown into a latrine pit, but only if the pit is not going to be reused.
