Bio solids are a nutrient- rich organic material resulting from the treatment of domestic sewage from a treatment plant.

The plant also sanitizes the solids of bacteria, viruses, and parasite so the transportation of disease is greatly reduced. There are three main uses of bio solids incineration, landfill disposal, and ocean disposal. Incineration method is preferred by some eastern U.S. cities.
