As a result of increasing demand for alternatives to fossil energy, the agricultural biogas sector is in expansion and lignocellulosic biomass (LCB) represents an interesting renewable feedstock. Nevertheless, due recalcitrance complexity its structure, deconstructive pretreatments are necessary render possible biochemical conversions efficient exploitation. In this work, chemical-free, mild mi...

Solubilization of sewage sludge creates favorable conditions for anaerobic microorganisms to produce biogas. In this paper, we quantify the effect of heating pretreatment on the degree of solubilization of sewage sludge. The pretreatment process was carried out using a lab-scale industrial microwave unit (2450 MHz frequency). Response surface analysis was applied to determine the combination of...
