An eco-friendly buoy includes a foam including a cylindrical accommodation space in the interior of the foam, and coupling grooves at predetermined intervals at an outer surface circumference of the foam in order to fasten the foam to fixing members through wire; and a protective layer formed on an entire outer surface of the foam and protecting the foam from damage by waves or wind. The eco-friendly buoy is manufactured from eco-friendly expanded polypropylene and expanded styrene and has a protective layer on an outer surface thereof, thereby being protected from damage by waves or wind. In addition, the eco-friendly buoy may be used for a long time, thus reducing maintenance costs.
