Abstract

Degradation of PBSA in pond water or soil was evaluated based on dissolved oxygen consumption rate in test water. PBSA placed in pond water or soil over several months showed more rapid degradation rate than new PBSA. In case of water, however, PBSA or biodegradable plastics have some risk of water pollution such as inrease of turbidity and oxygen demand.
