Claim:
1. A method of producing sugars using a screw extrusion process, the method comprising: hydrolyzing one or more lignocellulosic materials with cellulase while conveying the one or more lignocellulosic materials through a screw extrusion process, the one or more lignocellulosic materials having been exposed to ionizing radiation; and discharging an extrudate from the screw extrusion process, the extrudate comprising one or more fermentable sugars released from cellulolytic hydrolysis of the one or more lignocellulosic materials; wherein the screw extrusion process utilizes a co-extruder having a first barrel and a second barrel; and conveying comprises conveying a first lignocellulosic material through the first barrel and conveying a second lignocellulosic material through the second barrel; and hydrolyzing comprises exposing the first lignocellulosic material to a first hydrolysis process and exposing the second lignocellulosic material to a second hydrolysis process.
