The present invention relates to an environmentally-friendly buoy comprising: a foaming body which has a cylindrical receiving space therein and coupling grooves formed in the edge of the outer surface thereof at intervals to be fixed to fixing members through wires; and a protection layer which is formed on the whole outer surface of the foaming body and prevents damage to the foaming body due to waves or wind. According to an embodiment of the present invention, the environmentally-friendly buoy prevents damage due to waves or wind by manufacturing the buoy using nature-friendly expandable polypropylene and expandable styrene and forming the protection layer on the outer surface of the buoy and reduces maintenance costs as the buoy can be used for a long time. |
