摘要

台灣地區的家戶垃圾，廚餘約佔二至三成，這些廚餘通常為含水量高又具油漬之有機物質，易於腐臭又影響環境衛生甚鉅，若能將其回收再利用，不但有助於達到目前政府極力推動的「一般廢棄物資源循環推動計畫」，朝向「垃圾零廢棄」的減量目標，而建立一個資源永續利用的社會。目前國內對於廚餘的回收再利用，多以養豬和製作有機堆肥為主，其中以成本因子為決定採用何種處理技術重要的考量因子，本研究因此建立混合整數規劃模型，將各種成本因子納入考量，包括：清運成本、建造費用、廚餘養豬之標售價格、堆肥之標售價格等等，以分析在不同條件下，廚餘回收之最佳方案。本研究並以台中縣為例，驗證所建立之模式之適用性。

Among the household garbage in Taiwan, the food waste accounts for twenty to thirty percent. The food waste is organic material which usually contains high proportion of water and fat, it turns rancid soon and thus raise public concern. However, if it is recycled or reused, it will help not only to improve the recycling program which the government strongly promotes to reach the goal of “zero waste”, but also to establish a sustainable resource-recycled society. For the moment, in Taiwan, the recycled food waste is mainly used for pig feeding or as organic compost. The primary treatment cost is the most important factor that decides which technique will be taken. Thus, this research aims to establish a mixed integer programming model which takes all kinds of costs into consideration, including the transportation cost, the construction fees, the selling price of waste food as pig feeding and as compost, etc, to analyze the best program for food waste recycling in different conditions. A study case in Taichung County is also demonstrated to realize the suitability and accessibility of the model.
