Sugar cane bagasse and banana peel are potentially useful waste products of the food industry since they are rich in cellulose and starch, and could act as constituents or fillers in biodegradable composite packaging materials. The goal of this work is to investigate the incorporation of sugar cane bagasse (SCB) and banana waste (banana bagasse/peel/fibres (BF) or banana flour rich in starch (BS)) in physically cross-linked poly (vinyl alcohol) films. Films were prepared combining PVA as the major component with SCB, BF and BS individually, and with combinations of SCB/BF and SCB/BS respectively. These were characterised physico-chemically, morphologically and mechanically both as fresh samples and following degradation experiments in water and in soil. Physical interactions between the components of these PVA-based composites were detected. Samples containing banana constituents exhibited high water content, while the inclusion of sugarcane bagasse diminished failure strength relative to PVA-BF, PVA-BS and a PVA control, possibly due to the hydration of the bagasse. All PVA-based composite samples presented higher porosity and biodegradation in soil compared to pure PVA samples, suggesting that the addition of natural materials in the hydrogel stimulate the local biota. Hydrolytic degradation led to residual acetate groups on PVA, while degradation in soil led to the absence of acetategroups, the presence of soil and indications of microorganism action on the samples (biotransformation of polysaccharides in low-molecular-weight sugars). The PVA/sugar cane bagasse/banana composite films exhibit key properties necessary for useful biodegradable materials including as food packaging materials. Sugarcase bagasse should be reserved for cases where high strain capacity is less important.
