為評估嘉義市之生熟廚餘產量及其後續去化方式與管道，本計畫透過實地調查方式瞭解生熟廚餘產量。首先掌握嘉義市生熟廚餘產源並取各產業產量較高者，實地進行廚餘種類及數量調查，經調查結果嘉義市每日產出且回收約22公噸生熟廚餘及有機廢棄物，因此在設備處理量規劃建議以20公噸/日為基準進行評估，以實際掌握並有效處理嘉義市所產生之生熟廚餘及有機廢棄物。 本計畫蒐集國內外13種最新廚餘回收再利用處理技術、應用實例，並分析其技術特性、應用方式與限制，依據嘉義市現況及需求為原則進行前置評估，初評提出5種適用嘉義市之可行技術組合方案，其中3種為興設廚餘再利用廠(廚餘脫水高速發酵廠、併同焚化廠之廚餘乾燥廠及中小型廚餘厭氧發酵廠)及2種為興設廚餘前處理廠(廚餘破碎製漿前處理廠及廚餘壓榨脫水前處理廠)。再藉由層級分析法(AHP)與加權總合法(SAW)評估出最佳建議方案為廚餘脫水高速發酵廠。 本計畫依最佳技術方案及優選場址(湖子內區段徵收環保用地)進行營運模式、財務分析、場址規劃、執行方案及成品處理方案等內容進行整體性規劃。經評估分析各種興建營運模式，鑑於本案屬小型規模公共建設之廚餘再利用廠，為提升民間參與本案之誘因，優先建議之興辦方式為「興建採用採購法統包方式、營運採用採購法第99條委外營運方式」辦理。就財務分析面分別依兩種不同處理量情境設算民間觀點與政府觀點之效益分析，考量民間觀點之處理費收入屬於代營運業者之收入，而依政府觀點，在業者有營利條件下，政府可收取權利金或與業者協議降低處理費用，財務評估結果為可行。 目前嘉義市為無自主性廚餘處理設施之縣市，因此有必要積極推動自有的處理設施，除解決廚餘處理高單價，建立自有品牌，並利於長遠的發展策略。

To determine the kitchen waste production and its processing and end-use channels, this project conducted on-site surveys to understand the cooked and raw kitchen waste generation. Initially, the Chiayi City’s kitchen waste sources were identified, and the highest production sources were selected to conduct kitchen waste type and quantity surveys. Results show that Chiayi city produces and recycles 22 tonnes of daily kitchen waste and organic waste. Therefore, the daily treatment amount is set at 20 tonnes/day. This project compiled 13 different state-of-the-art kitchen waste recycling and treatment technologies and their actual cases of application, with analysis of their characteristics, applications and limitations. According to Chiayi city’s current status and demand to conduct a preliminary assessment, initially 5 types of feasible technical plans were proposed, 3 of which are building a new kitchen waste reuse facility (including a kitchen waste dehydration high-speed fermentation plant, a kitchen waste drying plant combined with incinerator, and a small to medium size kitchen waste anaerobic fermentation plant), 2 of which are building a new kitchen waste pretreatment facility (including a kitchen waste crushing and pulping pretreatment plant and a kitchen waste pressing and dewatering pretreatment plant). Then through the Analytic Hierarchy Process (AHP) and Simple Additive Weighting (SAW) approach, the best recommended approach is chosen to be the kitchen waste dehydration high-speed fermentation plant. This project will be based on the best technical solution and best site selection (Neihu district government acquired environmental protection land) for conducting the operation mode selection, financial analysis, site planning, execution of plan, and end-use product handling approach for overall planning. Upon analysis of each operation mode, and given that this project is categorized as a small-scale public construction, and in order to increase participation incentives, it is best recommended that the way of developing this construction should apply “conducting the procurement on a turn-key basis, while the operation mode should apply Article 99 of the Procurement Act by retaining a subcontractor”. With respect to the financial analysis, 2 different scenarios were used to predict the public and government’s perspective and their respective benefit analysis. Considering the public may see the treatment fee as part of the operating agency’s income, while from the government’s perspective, under the operating conditions, the government can collect royalties or negotiate with the operator to reduce treatment costs. Currently, Chiayi city is the only a city without its own kitchen waste treatment facility in Taiwan. Therefore it is necessary for Chiayi to actively develop its own treatment facility. Besides solving the high cost of treating kitchen waste, cultivating its own brand, it may also serve as a long-term development strategy.
