Study on strategies to allow the integral use of lignocellulosic biomass


Lignocellulosic biomass represents an abundant and renewable source of carbon for the production of biofuels and diverse bioproducts, which can supply many of the modern society demands in a more sustainable and environmental-friendly way when compared to the procedures currently used. To assure the sustainability of the biomass conversion processes, it is important to optimize and to combine methodologies of extraction, synthesis and fractionation to allow a more integral use of the various components present on the lignocellulosic residues, including carbohydrates, lignin, proteins and extractives. The aim of this project is to study plant cell wall fractionation in some biomass types, optimizing the main processes for the production of bioethanol and cellulose nanowhiskers and focusing not only on the final products, but also evaluating the potential applications of the co-products obtained in the diverse steps of the conversion process. The main biomasses to be investigated will be eucalyptus pulp and sugarcane bagasse for the production of cellulose whiskers, and also elephant grass, both for bioethanol and whiskers production. The results obtained in the project will allow the development and the optimization of the methodologies for bioethanol and cellulose nanoparticle preparation in these biomasses, minimizing process time and energy consumption, but also searching to decrease the volume of useless co-products and to maximize the products that may follow in future synthesis routes, leading to an integral use of biomass, within the biorefinery concept.
