The cost and environmental impact of food waste treatment depend on the technology selected to process food waste. In this study, five treatments including swine feeding, dried feeds for chicken, compost, anaerobic fermentation and incineration, have been examined and evaluated by life cycle assessment and cost analysis to evaluate the respective environment impacts and cost of a treatment. In addition, mathematical programming models were developed to analyze the optimal food waste management strategy based on minimal cost, minimal environmental impacts, respectively. The analyzed results indicate that the best treatment are compost and swine feeding under minimal environmental impacts, while dry chicken feed, swine feeding and compost are by order preferred for minimal cost oriented. An multi-objective programming model, is also developed and a case study in Taichung area was also analyzed to demonstrate the applicability of the developed model. Keywords: food waste, Life cycle assessment, cost-effective, mathematical programming model, replacement-effective.
