Hepatitis virus is a real hazard in handling biosolids. They are also more than just human excrement. Chemicals are often disposed of by pouring down the drain. The accumulation of heavy metals such as copper, zinc and arsenic can be problematic on soils where biosolids are applied. Composting can chelate metals but can't make them disappear.


Sure organic meal fertilizers can have junk in them but I think your generalizations are too broad.
