Owing to the recent advances in biopolymer field, the production of biocomposites is growing exponentially. Herein we report production and biodegradation studies of poly(butylene succinate) and nanocellulose composites. PBS is emerging biopolyester with properties comparable to polyethylene and polypropylene and compatible with conventional processing technologies. Considering the biodegradable properties of PBS and cellulose, we designed functional materials for advanced applications and non-toxic disposal routes. We compared conventional solvent casting method with our improved concentrate production and melt processing for enhanced properties. Loadings from 1 to 50 wt.% were prepared and tested under composting conditions (58°C, >50% humidity) to study accelerated disintegration of the prepared samples. Disintegration process was characterized by differential scanning calorimtery (DSC), Fourier Transform Infrared Spectroscopy (FTIR), laboratory scale testing and visual observations.
