These days, synthetic polymers threat to natural ecological systems. Biodegradable polymers have attracted as an alternative to current traditional thermoplastics. Accordingly, various biodegradable aliphatic polyesters including Poly(ε-carpolactone), Poly(lactic acid), and Poly(butylene succinate) (PBS) have been developed. Among them, PBS is one of the most promising biodegradable polyesters because of their low production cost and variable applications such as tissue engineering and fishery net. However, the mechanism of PBS-biodegradation is not completely discovered. In this study, PBS fibers are biodegraded in compost conditions. Fibers are buried in artificial compost during certain periods in 60℃ conditions. There were no weight-changes but we could verify evidences and establish mechanisms in biodegradation of PBS fibers indirectly. The PBS-biodegrading in compost conditions will contribute to the effective management of environmental problems. |
