| Abstract |
According to the circular economy concept, developing packages based on biopolymers and agricultural residues and evaluating their environmental impact should be a global sustainability initiative. Thus, this work is focused on the design of biofilms using sustainable materials (starch and Agave fibers) modified by a green single-step method (GSSM) by ultrasound. Regardless of the botanical source (rice, corn, and potato), the morphological analysis revealed the disruption of starch granules in all sonicated films, which promoted higher content of amylopectin leaching out from the granules to the continuous matrix, increasing the proportion of double helices with more packing as short-range crystallinity and thermal analysis indicated. These changes, in combination with the high interaction with fibers, improved the stiffness values as the storage modulus indicated. The cradle-to-gate inventory-based study of economic and environmental impact demonstrated that corn starch and the GSSM process have the best eco-efficiency among the other starch sources and conventional methods evaluated. Furthermore, starch films containing Agave fibers showed the lowest environmental impacts regarding global warming, ozone depletion, freshwater eutrophication, land use, fossil resource scarcity, and water consumption. These findings can help producers and decision-makers understand the environmental and economic impact of the processes and raw materials used to develop sustainable packaging materials. |
