| Novel polyester–polyurethane polymeric materials were formulated by combining a nat- ural aliphatic polyester, poly(3-hydroxybutyrate) (P3HB), with a synthetic aliphatic poly- urethane via melt blending. The resulting fully biodegradable compositions were func- tionally modified through the incorporation of urea, with the aim of enabling post-con- sumer utilization of the material residues as nitrogen-rich fertilizers. The fabrication pro- cess was systematically established and optimized, focusing on homogeneous blending and processability. Comprehensive mechanical characterization—including tensile strength, impact resistance, and Shore hardness—was performed. Among the tested for- mulations, composites containing 1 wt.% urea demonstrated superior mechanical perfor- mance and optimal processing behavior. Fourier-transform infrared (FTIR) spectroscopy was employed to investigate molecular-level interactions between polymeric phases and urea, while scanning electron microscopy (SEM) was utilized to assess the morphological characteristics of the resulting biocompositions. Comparative analyses of the physico-me- chanical properties and biodegradability were conducted among the urea-modified com- positions, binary P3HB–polyurethane blends, and neat P3HB. The observed improve- ments in mechanical integrity and functional biodegradability suggest that the developed urea-enriched compositions are promising candidates for the fabrication of eco-friendly seedling pots via injection molding technology. |
