“…In the past, carbon‐based or inorganic fillers were used to achieve high physical properties; however, the resultant residue after degradation had a negative impact on the environment. Therefore, it is reasonable to use biomass‐derived or organic fillers that have no environmental impact after degradation and maintain the properties of biodegradable polymers 8–10 …”

Sustainability has become increasingly important as environmental issues continue to rise. Biodegradable polymers offer a sustainable solution as they use biomass. In this study, biochar (BC) prepared by the pyrolysis of biomass was compounded with polybutylene succinate (PBS) to enhance its Young's modulus, and the residual BC was shown to amend the soil, following degradation. The incorporation of biochar into the PBS matrix is strategically achieved through a BC with treatment involving an aprotic polar solvent. This process not only reduces the size of the biochar particles but also ensures their uniform dispersion within the PBS matrix. As a result, a remarkable 2.5‐fold increase in Young's modulus is observed, reaching an impressive 571.04 MPa, compared with the baseline Young's modulus of neat PBS, which stands at 220.92 MPa. Interestingly, the degradation rate of the resulting composites was comparable to that of neat PBS despite the decrease in the number of potential hydrolysis sites owing to the increased Young's modulus of the PBS/BC composite. These sustainable composite exhibited properties different from those of conventional PBS and is expected to be used in potentially novel applications toward environmental sustainability, such as in agricultural mulch films or electronic printing.
