“…Using these waste streams as raw materials to produce energy is a rational valorization strategy. Recovering energy with a reduced carbon footprint [14] is possible through different routes, such as thermal conversion via gasification [15], pyrolysis [16], or combustion [17], hydrolysis and fermentation to ethanol [18], bioconversion to other liquid biofuels [19], or anaerobic digestion to biogas [20]. Despite the immense efforts being undertaken to implement economically feasible techniques to convert residual biomass into advanced energy carriers, developing novel valorization approaches of commercial relevance is still a major requirement.…”
