do biosolids smell like?
Biosolids are an organic material and when managed appropriately will typically have a weak, earthy smell. This smell is not unpleasant. However, as with any organic material, if not properly managed, the natural decay process can produce strong, offensive odours. Therefore, one of the key focuses in biosolids management is ensuring that offensive odours are not generated. Management practices to avoid offensive odours include stabilising (chemically or biologically) or drying the biosolids to stop the natural decay process, or incorporating biosolids into topsoil after land application.
