The present invention is to prevent pollution caused by residual plastic in seawater by manufacturing buoys by injection molding raw materials containing biodegradable plastic. The present invention provides a biodegradable buoy which consists only of biodegradable plastic parts. The biodegradable plastic part is made of PLA, PBAT, and impact-resistant reinforcement. The PLA is provided at 85 w% to 90 w% of the total weight of the biodegradable plastic part, the PBAT is comprised of 5 w% to 10 w% of the total weight of the biodegradable plastic part, and the impact-resistant reinforcement is provided in an amount of 3 w% to 5 w% of the total weight of the biodegradable plastic part.
본 발명은 생분해성 플라스틱부만으로만 이루어지며, 상기 생분해성 플라스틱부는 PLA, PBAT 및 내충격 보강재로 이루어지는 것을 특징으로 하는 생분해성 부표에 관한 것이다.
