This invention is directed to systems, devices and methods to beneficiate heat-dried biosolids or sludge pellets or granules as presently manufactured by municipalities or companies from a) dewatered municipal wastewater biosolids or sludges within the municipal wastewater treatment plant heat-dried biosolids production facility or from b) finished dry heat dried biosolids pellets or granules in a separate manufacturing facility from the municipal wastewater treatment plant to produce a fertilizer containing sufficient organic and inorganic plant nutrients to be valuable and saleable into the commercial agricultural industry. The present invention describes beneficiation methods to increase the plant nutrient content of the fertilizer and also to reduce the odors associated with traditionally-produced heat dried biosolids.
