Abstract
The poor biodegradation of liquefied biopolymer extricate and faster ingesting of hydrogengas, hydrogen production from control sample (raw waste biomass) with seed sludge
practicability is limited. In the present study, hydrogen gas generation potential of paper
industry waste(PIW) biomass was studied using sonication. During sonication mediated PIW
biomass pretreatment, power input and specific energy were varied for liquefied biopolymer
extricate. At optimum power (175 W) and specific energy (30667kJ/kg TS), sonication
method obtained 2330 mg/L of liquefied biopolymer extricate during PIW biomass
pretreatment. Then, the substrates namely sonication pretreated PIW biomass and control
(raw PIW biomass) were subjected to hydrogen assay. At 384 h of digestion, sonication
method got a maximal hydrogen production (17 mL/g VS) compared to control (3.8 mL/g
VS).Therefore, sonication mediated PIW biomass helps to diminish the biomass generation
by ameliorate the complex biopolymer liquefaction for boosting hydrogen production at large
scale.
