The present invention relates to an environmentally-friendly system and a method for treating food waste in an environmentally-friendly manner, whereby, when a bag of food waste is admitted through an opening unit, the bag of food waste is automatically weighed and transferred to a reactor, and in the reactor, the bag of food waste is crushed, thermally decomposed and combusted by a high-temperature plasma torch of approximately 1,300C, and finally, particulates and hazardous components in the exhaust gas are effectively removed, and only purified gas is ejected to the outside. The system for treating food waste according to the present invention comprises: an opening unit which includes a hopper into which a bag containing food waste is introduced, and a conveyor unit which transports the bag introduced into the hopper; a combustion treatment unit; and an exhaust gas treatment unit which is connected to a gas exhaust opening of a reactor, and removes particulates, carbon monoxide, and NOx from a gas and a fluid mixture of particulates discharged through the gas exhaust opening, before emitting the same to the outside, wherein the combustion treatment unit comprises: a reactor having the opening unit through which the bag containing food waste transported by the conveyor unit is introduced; a crusher which crushes the bag containing food waste introduced inside the reactor; a plasma torch which is installed at an upper part of the reactor to apply a plasma flame to, and thereby combust, the food waste being crushed by the crusher; an ash discharge door which is installed at a lower side of the reactor to open or close a discharge opening formed at a lower part of the reactor; and the gas exhaust opening which is installed at one side of the reactor to discharge to the outside, gas and particulates generated during the combustion process. 본 발명은 음식쓰레기가 담겨진 봉지를 투입구를 통해 투입하면, 그 무게를 자동으로 계량하여 반응기로 이송하고, 반응기에서 음식쓰레기 봉지를 분쇄하면서 1300℃ 정도의 고온 플라즈마 토치로 열분해 연소 처리하고, 배기가스의 분진과 유해 성분을 효과적으로 제거한 후 정화된 가스만 외부로 배출할 수 있도록 한 친환경적인 음식쓰레기 처리 장치 및 방법에 관한 것으로, 본 발명에 따른 음식쓰레기 처리 장치는, 음식쓰레기가 담겨진 봉지가 투입되는 호퍼와, 상기 호퍼에 투입된 음식쓰레기 봉지를 이송하는 컨베이어유닛을 포함하는 투입부와; 상기 컨베이어유닛을 통해 이송된 음식쓰레기 봉지가 투입되는 투입구가 형성되어 있는 반응기와, 상기 반응기 내부로 투입된 음식쓰레기 봉지를 파쇄하는 파쇄기와, 상기 반응기의 상부에 설치되어 상기 파쇄기에 의해 파쇄되는 음식쓰레기에 플라즈마 화염을 가하여 연소시키는 플라즈마 토치와, 상기 반응기의 하측에 설치되어 반응기의 하부에 형성되어 있는 배출구를 개폐하는 회분배출도어와, 상기 반응기의 일측에 설치되어 연소 과정에서 발생하는 가스와 분진을 외부로 배출하는 가스배기구를 구비하는 연소처리부와; 상기 반응기의 가스배기구와 연결되어 가스배기구를 통해 배출되는 가스와 분진의 혼합유체로부터 분진과 일산화탄소와 NOx를 제거하여 외부로 배출하는 배기가스처리부를 포함하는 것을 특징으로 한다.
