This paper describes an economical means to recover nutrients from organic waste streams and, as an alternative to disposal, formulate them into high integrity granules for agriculture and specialty fertilizer products. Generators of waste streams such as manures, litters and sludges are becoming both financially and physically burdened with accessing adequate land for waste application. With mandated farm nutrient management planning, low cost land application of organic wastes is increasingly controlled. Many states limit waste application rates by nitrogen or phosphorous loadings tied to the needs of the subsequent crop and further reduce application rates by taking into account the nutrients from other materials, including crop residue, commercial fertilizers and current or previous applications of other waste streams. Although most of the waste streams are dilute, low density, amorphous and generally unusable in their raw forms, technology exists to upgrade them into high value products.
