Effect of Different Sugar Beet Pulp Pretreatments on Biogas Production Efficiency.

The objective of this study was to determine the effect of different sugar beet pulp (SBP) pretreatments on biogas yield from anaerobic digestion. SBP was subjected to grinding, thermal-pressure processing, enzymatic hydrolysis, or combination of these pretreatments. It was observed that grinding of SBP to 2.

Effect of enzymatic pretreatment on anaerobic co-digestion of sugar beet pulp silage and vinasse.

Results of sugar beet pulp silage (SBPS) and vinasse (mixed in weight ratios of 3:1, 1:1 and 1:3, respectively) co-fermentation, obtained in this study, provide evidence that addition of too high amount of vinasse into the SBPS decreases biogas yields. The highest biogas productivity (598.1mL/g VS) was achieved at the SBPS-vinasse ratio of 3:1 (w/w).

Effects of hydrothermal pretreatment of sugar beet pulp for methane production.

The effect of Liquid Hot Water treatment conditions on the degree of sugar beet pulp (SBP) degradation was studied. The SBP was subjected to hydrothermal processing at temperatures ranging from 120 to 200 °C. The relationship between processing temperature and parameters of liquid and solid fractions of resulting hydrolysates as well as the efficiency of their methane fermentation was determined.
