Polylactide-based renewable composites from natural products residues by encapsulated film bag: Characterization and biodegradability

► Using polylactide and natural products residues (corn starch) composites as a film bag material as bacterial fertilizer. ► Both of PLA and corn starch were biodegradable and absolutely harmless on environment. ► When the controlled-release film bags were degraded and the phosphate-solubilizing bacterium was released. ► The biodegradability of the bacteria-encapsulated film bag depends on the type of material used.
