Evaluation of Performance Index for Optimization of Food Waste Treatment and Recovery Facility

This research was performed to evaluate the food waste recovery facility using optimization performance index. In 2014, the generated amount of food waste occupied approximately 27% in total municipal solid waste. The 97.2% of the food waste was recycled and the others were treated through landfill and incineration in the portion of 0.9% and 1.9%, respectively. In food waste recovery facilities of year 2014, the composting and feed facilities were 49.5% and 22.9%, respectively. The feed facility showed higher scores in all technological, environmental, and especially economical evaluations than those of composting facility. As results of overall optimization performance index, the feed facility has higher score of 61.5 than 52.7 of composting facility. It was demonstrated that the feed facility has the advantage, compared with the composting facility.
