Method for treating animal waste and other waste streams

摘要

A composition of one or more farm animal waste streams is made by bio-digesting the stream and then granulizing it, the granulized product being in a range of 0.1 to 0.5 inches in diameter and having a moisture content no greater than 15% or, more preferably, no greater than 7%. The method for making the composition includes the steps of (i) processing the farm animal waste stream in a bio-digester and (ii) granulizing the bio-digested farm animal waste stream. The bio-digester is preferably at a high temperature in a range of 160° to 180° F. The bio-digested farm animal waste stream can be mixed with a binding material such as coal-ash, sawdust, or an equivalent. The composition can then be applied sub-surface using a box or air seeder.

(i) processing the chicken litter in a bio-digester; and (ii) granulizing the bio-digested chicken litter to a moisture content no greater than 7%; (iii) sizing the granulized bio-digested chicken litter to a size appropriate for sub-surface application with an air or box seeder; and (iv) applying the granulized product sub-surface with the air or box seeder, a depth of the sub-surface application being at least 2 inches below surface level.
