The invention relates to a method comprising: irradiating a layer of lignocellulosic material with a series of doses of radiation, using more than one electron beam device, to deliver to the lignocellulosic material a total dose of radiation of at least 10 Mrad; cooling the irradiated lignocellulosic material using a heat exchange system; and hydrolyzing the irradiated and cooled material with an enzyme or microorganism to produce sugars. |
