Abstract
Recent years recycling is recommended as one of environmental pollution control measures. In this study, we report the effect of material recycling on mechanical properties of poly (butylene-succuinate) (PBS). After fifth cycles of reprocessing, bending strength and bending modulus remained constant. Then the effect of reprocessing on bending strength after immersion in water was evaluated. By reprocessing the material degraded by absorbance the bending strength recovered to that of virgin material. This is because the water absorbed into the material is removed during reprocessing. By reprocessing the material degraded by hydrolysis, the bending strength remained constant compared with before reprocessing.
