Abstract

Background/Objectives: Since food waste was prohibited from being buried in the ground, each municipal government has installed food waste treatment facilities, and has treated the food waste by a method of making compost or feeds. Methods/Statistical analysis: However, in case of compost, salt could not be removed, accordingly the compost acted as a factor in withering the crops or hampering their growth. In case of making feeds, a problem of killing livestock was caused because it was not possible to remove toxicity that might be contained in the food. Therefore, a vicious circle was created, where food waste that could not be used as compost or feeds became waste again even after being treated. Findings: As a result, we got 4431kcal/kg as a heating low value from the dried food waste, so after heating around 400°C, the exhausting gas can be used as a fuel. Also we got the useful components ratio of 0.42%(N), 0.02%(P) and 0.4%(K) from condensate water, so this condensate can be used to liquid compost. Improvements/Applications: Therefore, this paper suggests measures for recycling the dried food waste into feeds or compost, reducing fuel costs by recycling the dry remainder into fuel, recycling the carbonized residues into cover soil, and utilizing condensate generated in this process as deodorant, external carbon source and liquid fertilizer.
