1. A process for treating solid waste comprising the steps of:

  • receiving untreated waste material at a receiving station;

    comminuting said waste material to provide a size limited material having a select maximum average particle size;

    elevating the moisture content of said size limited material by the agitation thereof in the presence of a select amount of water to provide a moisturized, size limited material;

    controlling the said select amount of water present during said agitation and controlling the residence interval of said agitation to derive a substantially uniform moisture distribution substantially throughout all portions of said size limited material of about 50 to 60% of the weight of said material;

    macerating said moisturized, size limited material without the further addition of moisture by subjecting it to counterrotative beating action to effect breakdown thereof to derive a pulpous material; and

    digesting and composting said pulpous material by inducing the aerobic decomposition thereof.
