This paper elucidates the pathogen concerns for animal wastes and municipal residuals and the applicability of current biosolids treatment processes to control their risks upon disposition. The importance of this are of focus can be attributed to the issues resulting from potential impacts of animal waste, these includes:

Possible release of infectious microorganisms with consequent public health concern.

High content of nitrogen in the waste (4 to 8% in cattle wastes).

High levels of phosphates in the waste (1.1% in dairy cow waste and 4.6% in hen waste)

High daily volume of cow waste (30 to 60 lbs. of manure and 2 to 4 gallons of urine per animal)

High quantities of BOD resulting in anaerobic degradation (emission of methane and hydrogen sulfide gases).
