Abstract

Disperser assisted homogenization is a promising mechanical based disintegration process to improve the substrate biodegradability and biogas recovery from biomass. During dispersion, the extent of liquefaction relies on the dispersion parameters and biomass properties. Hence, assessment of the optimal parameters varies with type of disperser and biomass. Dispersion assisted homogenization of some biomass such as sludge is not only studied in lab scale but also investigated in full scale plants providing positive outcome. For instance, the large-scale investigation of disperser homogenization has attained nearly 40–50 percent increment in bioenergy recovery. However, research gaps in terms of energy and cost efficiency still exists. This review paper outlines the impact of disperser parameters, its efficiency in biomass disintegration and biogas recovery. It has been proposed to combine homogenization process in the bioenergy generation to investigate the energy and cost efficiency of the entire process.
