Biodegradation behavior of aliphatic polyesters in seawater |
| 초록 |
Polybutylene succinate (PBS) is one of the biodegradable aliphatic polyesters that would be degraded by microorganism and can solve the environmental problem caused by waste plastics. However, the biodegradation studies on PBS have been conducted in mostly soil or compost condition, and rarely done in water condition. In this study, the biodegradation test in seawater was conducted and compared with the result of the compost test, that is done according to the ISO 14855-2 method using microbial oxidative degradation analyzer. The biodegradability with seawater condition was lower than the one with compost condition despite its longer degradation time than the compost one, which might be due to its low concentration of microorganisms with the low temperature. On the other hand, accelerated test was also performed in the same seawater and its result was not far from the compost condition. |
