The large-scale industrial use of polysaccharides to obtain energy is one of the most
discussed subjects in science. However, modern concepts of biorefinery have promoted the
diversification of the use of these polymers in several bioproducts incorporating concepts of
sustainability and the circular economy. This work summarizes the major sources of agro-
industrial residues, physico-chemical properties, and recent application trends of cellulose,
chitin, hyaluronic acid, inulin, and pectin. These macromolecules were selected due to their …
