Abstract: Disclosed are systems and processes for drying livestock manure to produce suitable end-products such as animal bedding and soil conditioner or amendments. Dried manure made by the process can be recycled into the burner. Exhaust gases from the dryer and cyclone can be cleansed of particulate and/or used to heat and aerate trenches and/or lagoons used to digest wet manure. Biomass may also be used as fuel in the burner. Biomass may also be blended with wet manure to decrease water content prior to being dried in the dryer.
