1. A method for treating sludge generated in a wastewater treatment system, comprising the steps of:

  • concentrating the sludge to increase the percent solids content by at least 1.5;

    selecting a desired homogenizing pressure based on an input energy required to disrupt the sludge;

    disrupting at least a portion of the cellular matter in the concentrated sludge at the desired homogenizing pressure;

    digesting the disrupted sludge to produce methane gas; and

    converting the methane gas to an available energy source that may be input to the wastewater treatment system, the input energy required to disrupt the sludge being substantially the same or greater than the input energy requirement.
