本計畫主要目的在於延續歷年全國各縣市之垃圾採樣及分析工作，透過縝密之採樣規劃與分析結果，建立長期連續性之垃圾基本特性資料，並掌握垃圾性質之長期變動趨勢；並期藉由本計畫之執行成果，作為未來制定未來垃圾處理政策、研發新穎資源回收與再利用技術、評估規劃安全性處理處置技術之重要參考依據。 根據今(102)年度採樣分析結果顯示，垃圾濕基組成中紙類、廚餘類及塑膠類約佔總物理組成比例之93.71%，其中紙類含量最高，約佔垃圾組成中41%，其次為廚餘類之36.53%及塑膠類16.18%，至於金屬類及玻璃類則分別佔0.45%及0.61%。皮革橡膠類、纖維布類及木竹落葉類含量之總和，約佔垃圾物理組成之3.80%。就本年度紙類及塑膠類之物理組成比例變化趨勢可知，均較近三年之移動平均值為高，分別由近三年平均值之38.7%及15.6%，增加至今年之41%及16.18%，亦即上述物理組成之比例，呈現逐年增加之趨勢。本年度廚餘類、金屬與玻璃類之組成比例，均較近三年之移動平均值為低，且呈現逐年降低之現象。此外，依據本年度採集垃圾中紙類之種類，主要以紙製衛生用品之其他紙類含量佔總垃圾之19%為主，至於紙張則約佔總垃圾之7%。垃圾中平均含水量為54.95%；由於垃圾中金屬、玻璃及其他無機成分含量較低，因此，可燃分均佔垃圾之40.86%以上；垃圾之平均低位發熱量為1960 kcal/kg。至於五個採樣縣市之垃圾中可燃物重金屬分析結果顯示，鋅、鉛、銅、鉻及鎘之平均含量，分別為20.2 mg/kg、4.94 mg/kg、11.0 mg/kg、10.1 mg/kg及0.656 mg/kg。根據長期垃圾採樣分析結果，有助於建立全國地區垃圾性質分析之完善資料庫，同時本計畫結果亦可提供未來垃圾管理策略之重要參考依據。

The objectives of this project were to establish the database of long-term physical and chemical characteristics of municipal solid waste (MSW) and to evaluate the variation of MSW composition and property by careful sampling, sample preparation and the analytical techniques. Therefore, this project was designed and implemented continuously for the sampling and analysis of municipal solid waste composition in Taiwan, from March 7, 2013 to March 6, 2014. This project was also well-planned to sample 22 MSW sources generated from municipalities in Taiwan (including 25 sampling points) once a season for every source and to analyze the physical and chemical compositions of MSW samples. In this work, the main analysis items were including physical composition, proximate analysis, ultimate analysis, energy content and heavy metals (Cu, Zn, Cr, Cd, and Pb) of combustible, respectively. In summary, according to the performance of this project, it can be useful in adopting the strategies of municipal solid waste management, developing the innovative technologies of recycling and recovery, and assessing the safe technologies of MSW disposal.
