| Sumario: | Biomass is envisaged as a plentiful resource to produce foods, chemicals, materials, and fuels. It is renewable by itself, though the sustainability of its processing toward the end products depends strongly on the technological basis of such processes. Bioprocessing of biomass is a nature-driven strategy based on the catalytic capacity of living beings and their macromolecules, particularly their enzymes. Lignocellulosic biomass, the main fraction of agricultural and forestall biomass, is created worldwide at a rate of 181,500 MT per year. Moreover, food loss and waste biomass is rich in vegetable tissues. All this biomass has been, to some extent, the reason for several environmental and societal problems but it is also a key feedstock, a set of diverse and plentiful secondary raw materials for first, second, and third-generation biorefineries. Such biorefineries are based on physicochemical transformations of biomass, as it is usually refractory to biological transformations, followed by enzymatic and/or microbiological and cellular transformations. These biotransformation processes are presently being optimized, to create energy (electricity), energy vectors (hydrogen, biofuels), chemicals (fatty acids and derivatives, monosaccharides, derivatives, etc.), biomonomers (diacids, hydroxyacids, etc.), and biopolymers (Polyhydroxyalkanoates or PHA, bacterial cellulose, exopolysaccharides, etc.). Still, the biorefinery concept was built based on the petrochemical refinery considering a holistic perspective of the use of matter and energy, while key knowledge from the food and paper sector is also integrated, creating complex, integrated biorefineries to take full advantage of biomass as a sustainable feedstock. |
