Abstract
System and apparatus for treating organic waste material, suited, for example, for the aerobic-thermophilic treatment of cattle manure. The waste material initially is commingled with an expanded, size limited dry cellulosic material in a mixing stage, preferably, a pug mill device, to achieve a bulk density and moisture content optimized for thermophilic digestion. A digestion arrangement is provided assuming a reliability for complete aerobic treatment of all material removed therefrom.
