The aim of this study was to elucidate the effect of hydrothermal pretreatment at 25, 100, 150 and 200 degrees C on fibre composition and the biomethane potential of sunflower oil cake (SuOC). An increase in pretreatment temperature from 25 to 200 degrees C caused a decrease in hemicellulose content in the solid pretreated fraction from 13 to 6% while the lignin content increased by 16%. Soluble compounds also increased with temperature. Digestion of solid fractions from pretreatments at 25, 100, 150 and 200 degrees C in batch assays at 35 1 degrees C resulted in methane yields of 114 +/- 9, 105 +/- 7, 82 +/- 7 and 53 +/- 8 mL CH4 g(-1)COD(added), respectively. The corresponding methane yields for the liquid fractions were 276 +/- 6, 310 +/- 4, 220 +/- 15 and 247 +/- 10 mL CH4 g(-1)COD(added). respectively. Therefore the overall methane yield was highest for SuOC pretreated at 100 degrees C; however, this value was only 6.5% higher than that achieved after pretreatment at 25 degrees C.
