The present invention relates to a marine waste recycling apparatus and a marine waste recycling method for recycling marine wastes such as starfish, jellyfish, and dead fish. Marine waste recycling apparatus according to the present invention, the upper surface is openable and openable, the body portion is provided with a powder processing chamber for accommodating marine waste therein; a magnetron part mounted on one side of the body part and heated by oscillating microwaves into the powder processing chamber; a rotary blade part installed inside the powder processing chamber and agitating and pulverizing marine waste; a sensor unit for sensing the temperature and humidity of water vapor discharged from the powder processing chamber; and when the temperature value sensed by the sensor unit is equal to or greater than a preset first temperature threshold, the magnetron unit is temporarily stopped to prevent carbonization of marine waste, and the detected temperature value is less than or equal to the second temperature threshold value and the detected humidity value is When it is less than the first humidity threshold, the heating operation of the magnetron unit is terminated, and a controller for terminating the grinding operation of the rotary blade unit when the detected humidity value is less than or equal to the second humidity threshold. The marine waste recycling apparatus and the marine waste recycling method of the present invention have the effect of processing marine waste into industrial resources and reducing environmental pollution.
